Improving Vaifai reception with your own hands. How to increase WiFi sensitivity in a laptop

To use such a blessing of civilization as wireless Internet, people are already accustomed. But not always satisfied with how well their devices are accepted or distributed Wi-Fi. Is it possible to do something about it? Of course, there are options. Depending on what exactly you want to get, there are several different ways.

Strengthen distribution

There are several universal ways that help to make the quality of the signal better. All of them, by the way, are registered in the instructions for devices (routers), but it will be worthwhile to repeat them. So, how to enhance the WiFi signal for distribution.

Location

Pay attention to where your router is located. The radius of devices is usually 25-30 meters. Mobile (those produced by cellular operators to work with their SIM cards and tariffs) are somewhat less - 10-12 meters. However, all this will be not enough if the router is incorrectly. So that the signal is distributed everywhere equally, it is advisable to put it in the center of the room. It is very important that metal items be away from it. They significantly worsen the quality of the signal. For example, in the kitchen, the router is better not to be placed. Plate, refrigerator and household appliances can greatly spoil you online.

Interference

To other frequent reasons for a bad signal include various kinds of interference. For example, mobile phone signals. The closer the router is located to the mobile phone, the worse it distributes the Internet. How to deal with it? Someone just sits away from the router with the phone, but there are those who generally radically solved the problem. Some resourceful users simply turn the equipment with food foil. Why is it? She does not miss microwaves that emits a mobile phone. That is, it does not affect the reception signal and the transmission as a result.

Antenna

If your router is equipped with an antenna, then with it you can significantly improve the Internet distribution. For example, your device is located on the closet in the room, and you most often sit in the corner at the table. Just turn the antenna to the side where you are usually you. So the signal will not leave. If the regular antenna is too short, with a small radius of action, then you can replace it. A special wifi signal amplifier is not suitable for each model, but some still support such an option. It will be worth consulted with specialists before buying.

Another router - interference

In apartment buildings, many use Wi Fi-technologies. And, of course, almost everyone has its own router. It often causes problems. Signals overlap each other, do not allow devices to work normally. How to deal with it? First, you can try to rearrange your router. Secondly, twist the antenna, giving directional signal. What is not always convenient. Thirdly, you can use reflectors. How to strengthen the WiFi signal with them? Look for such devices in specialized stores. They usually attach to the antenna without giving the signal to spread beyond the foil. Yes, reflectors are made of it. Can be made independently, giving the desired form to the device. In this case, the signal from the neighboring router will simply not fall to you. So, distribution of the Internet on your device will significantly increase.

How to strengthen the reception on the smartphone?

Modern cell phones Not bad and pretty quickly catch various wireless networks. That's just not always well hold the signal. Especially when he is not from your router, but, for example, neighbor. Can you fight this? How to strengthen the WiFi signal to receive?

Special applications

If your phone works on the Android platform, there should be no problems with the amplification. Play Market. Contains a sufficient number of different applications that help to enhance the reception of the Wi-Fi signal. Testing several, you can stay on some one, ideally responsible for your requirements. Wi-Fi Overview 360, by the way, has earned many flattering reviews from grateful users. The application allows not only to increase the reception of the signal, but also significantly increase the reception radius. You may be caught even those distributions that are quite far from you.

For Apple products

Developers of the well-known company devices have taken care that their buyers do not suffer from poor signal quality. However, in addition to the iTunes catalog, different amplifiers appeared. Some on a paid basis, some gratuitous. For example, WiFi signal amplifier for Apple Wi-Fi Boost enjoys special demand because it has both Beta and Pro version. This application allows not just to catch a good signal, but also secure it to hold it. According to the principle "I caught - I will not let it go." Of course, in the reasonable limits of your movement from the location of the router.

Frequency

Usually wi-fi signals set all devices per standard frequency. And it is precisely that plays a significant role in handing out and reception. Especially if in an apartment building of such devices several. How to deal with it? How to strengthen the WiFi signal in this case? Change frequency! Of course, if it is supported by your router. Carefully read the user manual of your device. Perhaps all actions are performed manually. But the owners of mobile routers fight the frequency and the distribution channel is useless. Until cellular operators Do not give such an opportunity. It is possible that over time this flaw will be corrected.

Special utilities

Does your computer or laptop have become bad to catch the signal? Or was it originally not very good taken? There are some utilities whose installation will help strengthen the reception of Wi-Fi. It is advisable to download them from the software developers sites, since many files on the network are loaded by fraudsters and hackers.

Speedtest.net.

In general, initially it was an application for mobile devices. And at the moment, the developers have created a computer utility that significantly improves productivity and PC itself, and receiving a Wi-Fi signal. The program interface is simple and understandable, all settings in Russian.

Drivers

Often the problem of receiving the signal lies in the fact that the system drivers are simply outdated. How to deal with it? First, update all drivers on a computer or laptop. You can do this on the official website of your device or software. Secondly, you need to update the drivers of your router. This will also require an official website. If you already have such an option as automatic update Software, you can use it. In the end, if it does not affect the quality of the signal, it will at least do not hurt.

Instead of output

Before rushing to extremes and download many applications and programs, first decide on the location of the router. It is from this that in most cases the quality of the signal depends on the distribution and on the reception of devices. Try to remove all interference from the router to the maximum distance. Remember that the higher the device is located, the less it will intersect with signals of other home appliances. For example, a microwave, even at a remote distance, may worsen the Wi-Fi distribution at times. If you rearrange the router to a height that does not intersect with it, then quality will increase. It is not recommended to install the device on the floor, since the flooring can adversely affect the Wi-Fi signal.

In June 2007, a record was recorded: the longest wireless connection is set (382.9 km) using a wifi connection. Probably, it would be unreasonable to hope to repeat it within the private WiFi networkAlthough it is a tempting idea. We bring to your attention a few simple tips that will help maximize the quality of the signal and minimize the amount of interference with a small wireless fan-shuya.

Steps

Improving the quality of WiFi reception at home

Position cumbersome furniture along the outdoor walls of your home. If the signals no longer have to break through the large, bulky furniture, then the level of communication quality will only increase.

Minimize the number of mirrors. All metal surfaces reflect WiFi signals, including a thin metal coating that has most mirrors.

Properly place the network router in order to maximize its efficiency. The efficiency of the router mainly depends on its correct location. It is best to have a router:

Improve reception quality using a repeater or wireless bridge. If your main thing workplace Located far from the wireless access point and you constantly have to move to the edge of the room in order to have a better reception, install the wireless relay. Wireless repeater allows you to increase the area of \u200b\u200bthe coating without having to add additional wires or other unnecessary troubles. In order to quickly and effectively improve the quality of communication - place the repeater in the middle of the path between the access point and your computer.

• Wireless bridge (also sometimes called an Ethernet converter) applies to improve the quality of reception for wired devices. If you have any problems with the quality of reception on your wired devices, use an Ethernet converter in order to obtain an additional speed gain.

1. Instead of the WEP protocol, start using WPA / WPA2. WEP and WPA / WPA2 are safety algorithms that do not allow hackers to hack the network. The only problem is that WEP ("Wireless Encryption Protocol" - Wired Equivalent Privacy) is much less safe compared to WPA / WPA2 (Protected Wireless Access Protocol - Wireless Protected ACCESS). . So if you are still using the Internet via WEP, not WPA / WPA2, then consider the possibility of transition in order to prevent the potential hacking of your network.

   Limit the number of devices for which your WiFi will support MAC-addressing. The smaller the devices support your network, the higher and more reliable the transfer rate (usually). Limit the number of devices that will be able to access the network by creating a permitted list of MAC addresses. The MAC addresses of devices is identifiers for "Access Control Access (Data)" - (Media Access Control) and all participants of your network are used.

   • Create a list of enabled devices of devices. To begin with, determine the MAC addresses of devices, and then go to the configuration window of your access point to wireless network And configure the allowed addresses.

2. Do not leave B. open access The name of your network. If you do not want other people to try to enter your network, then first do not leave them any opportunity to learn that it exists. (Despite the fact that there is softwarewhich is capable of finding "hidden" networks, you still do not need to leave your network name in public domain.) Go to the Administration page of your access point and uncheck the Allow SSID Transfer check box. You can still get access to your network, but it will not be displayed on the computer in the list of available networks.

   Use of kitchen foil

   1. Use aluminum foil in order to reflect radio signals from the router.

      Before proceeding before, go to the network connections on the computer. Click on the name of your WiFi network. Another window will open. Pay attention to the speed / Mbit / s and write down the displayed number (for example, 72.2 Mbps). After you do this - tear the foil sheet, the size of the usual A4 format.

      Carefully bend foil sheet. It is easier and faster to do if you wrap a 2-liter plastic bottle in the place where the label is glued, and hold the sheet in such a position for about 5 seconds. Expand sheet; He must have a curved form.

      Place the curved foil sheet on its side (so that it remains in a horizontal position) behind the router.

      Return to settings for network connections. Check Mbps / Speed. It should increase compared to the speed that was before the addition of foil.

   Improving the quality of wifi reception on the road

   • If nothing helps, you can think about buying a WiFi repeater, which is necessary to enhance the signal between the router and the device.
   • You can also use reflectors. Use the NetStumbler program in order to properly place the reflector. As a reflector, you can use a CD, as well as anything that looks like a parabolic reflector. Reflector, of course, it is necessary to post behind the receiving device or antenna. As a result of its application, you can expect a large increase in signal strength. This focus also works with mobile phones.
   • Depending on the brand and model of your wireless router, you can replace the built-in software to other - open source codewhich will add much more features to set up and increase the power of the wireless antenna
   • The computer case itself can be a significant obstacle on the Wi-Fi signal path - try placing the case so that it does not create the barrier between network card and antenna router.
   • Adding an external antenna with a "high gain" (with a higher DBI value) often leads to an increase in signal reception quality and performance growth. It should be noted that the greater the DBI value, the stronger the signal spreads in the horizontal direction and is weaker in the vertical. If you need to cover several floors, the higher level of DBI will probably not help you. In this case, you should think about buying a Wi-Fi amplifier that will enhance your signal.
   • If you still need a larger coating range, then think about updating the version of the used version wireless Standard Before Wireless N or Wireless G with MIMO. These two technologies significantly increase the range of existing 802.11g or 802.11b networks.

   Warnings

   • Replacing the router firmware may result in cancellation warranty. If the replacement is not done properly, it can lead to irreparable damage to your router.
   • If you feed too high power on a wireless router modified in this way, it may permanently fail.

We remind you that attempts to repeat the author's actions can lead to a loss of a guarantee for equipment and even to failure, as well as problems in the work of software and OS. The material is given exclusively for informational purposes. If you are going to reproduce the actions described below, we strongly advise you to carefully read the article until the end of at least once. The 3DNews edition does not bear any responsibility for any possible consequences.

In general, materials with tips on setting up Wi-Fi in the network countless, but not all of them are equally useful. Strictly speaking, there is simply no universal council on this topic: everyone has different models routers and client devices, different working conditions and so on. But everyone's problems are the same: low connection speed, breaks, high delays. Nevertheless, we tried to collect the most relevant advice on their decision, making focus on simplicity. There are no chant technical things here, and the terms are the most-minimum. This is a conscious simplification.

Please note that the most typical situation is considered in an ordinary city apartment with one router. However, for a private one-story house, the principles are the same, but for two or more floors there are already nuances. Options with signal repeaters, additional access points and other triggers like PLC are not considered. The material is built according to the following principle: at the very beginning there is a list of key points, and then more detailed explanations for each of them. Each section does not depend on the other, that is, you can not fulfill the recommendations in the order that is shown in the article. Go!

Proper placement of router

Place the router is necessary so that:

• he, if possible, was equidistant from client devices and was not at the window;
• between the router and clients, as little as possible barriers from materials that strongly affect the signal;
• nearby there were no sources of electromagnetic radiation and powerful electrical appliances - especially microwaves, radionias, radio tubes and their bases;
• at least at the level of the usual working / writing table or higher, but not on the floor;
• antennas or housing were located as indicated in the instructions (for external antennas normally vertical location);
• he was freely ventilated and cooled;
• the most critical device quality device could be connected via cable, not by Wi-Fi.

Before digging somewhere in the settings or engage in other shaders, it is worth trying the easiest way to improve the work of home Wi-Fi - to properly place the router. Often, users are not interested in this question, and the installers of the provider do not burn with the desire to do additional workSo the router is placed there, much closer and easier to start the external cable. As a rule, it is an entrance hall or room closer to the shield on the site, which is not always optimal. In general, some universal for all advice is difficult to give, therefore it is better to experiment with the placement of the device. If it is possible to connect sensitive to access to a network of device on a wire, then it is best to do that. Wi-Fi is good, and "copper" is better!

The best option in theory is the placement of the router in the center of the apartment, at least somewhere at the table level or higher. The thing is that the antennas in home routers are almost always omnidirectional. If we speak quite simplified, then on top you can imagine that the signal is separated from the router with concentric circles, gradually weakening. So if it is located, for example, in the corner of the rectangular apartment, then three quarters of the coating will be abroad. It is clear that to put the device into the center is unlikely to succeed - it is necessary to somehow bring the provider and power cable. But on the plan of the premises, you can at least figure out where it can be placed so that the coating is maximum. And at the same time evaluate where the largest concentration of customers or where the most sensitive Wi-Fi-devices will be located - here's closer to them and you need to put a router.

At the same time, several more factors should be taken into account. The wireless signal in the open space is well distributed, but in real life between its source and consumers there are always some obstacles that affect it to one extent - absorb or reflect. These are walls, doors, interior items, household appliances and so on. The objects with a large metal content are the strongest on the signal: doors or beams, reinforced concrete walls and overlaps, metalized and mirrors, large household enclosures like a plate or refrigerator, some ceramic coatings and products. Little, but still very noticeable effects have large water volumes (large aquarium, for example), brick and stone (usually as part of walls), some finishing materials and insulation. Well, weaker influence objects from plastics, wood, ordinary glass, drywall, fabrics.

Now the Wi-Fi standard is able to work in two radio bands: 2.4 and 5 GHz. And the 5 GHz signal fastens faster than 2.4 GHz. A feature of both ranges is that they were generally initially not intended exclusively for Wi-Fi. On the contrary, these frequencies do not require licensing and separate registration of devices while complying with some rules, primarily relating to radiation power. In fact, in the same region of 2.4 GHz, many sources of signals coexist, which in this case are interference. These include various radio-controlled devices (from machines to drones), radionia, wireless music systems, radiotelephones (not DECT), keyboard / mouse and other manipulators with their own adapters. In general, all kinds of proprietary and not very communication systems, as well as a Bluetooth device, although it is specifically for BT that came up with the mechanisms of coexistence with Wi-Fi.

But this is really not all. Do you know what the worst animal for Wi-Fi? Ordinary microwave! It also works in the range of 2.4 GHz, and no protection saves from a powerful radiation leaks, which, at best, simply reduces the speed and stability of data transmission via Wi-Fi, and in the worst - the network completely extends. In the next place for the harmfulness of the same radiotelephones and radionans, which even in standby mode will seriously. And we do not consider hard cases when all sorts wireless systems naturally eaten the frequencies of several wi-Fi channelsAlthough the standard does not match. In general, virtually any electrical engineering can somehow generate electromagnetic noise, which does not necessarily affect the Wi-Fi directly, but completely capable to influence other components of the router. And from her router it is better to keep away - a minimum of meters in a pair. There is, however, another source of interference directly inside the modern routers is uSB ports 3.0! But they have long learned to cope with them: they are isolated from radio frequencies, and in the settings you can always turn on USB 2.0 mode. Also, a good helps from problems with them uSB cable 3.0 with normal shielding.

And of course, to interfere with your Wi-Fi can ... right, someone else's Wi-Fi! All modern routers in obligatory Regularly scan radio ester to work better. We will talk about the settings of the channels just below, but so far there is enough knowledge of the fact that your router constantly "listens" what is happening around. The above example with the placement of the device in the corner is bad not only by the fact that you ourselves lose the coating, but also in that this way the router begins to "hear" the neighbor Wi-Fi, which is most likely to your client devices of such a strong influence does not. For the same reason, you should not put a router by the window yes to the windowsill, since he probably "learns" about a pile of neighboring networks, which certainly do not "finish." Residents of a number of cities can separately "thank" one major ISP, which is not he himself, and dishonest subcontractors, strictly speaking - with the global network update, even grandmothers put routers with the Wi-Fi enabled, which they do not need a hundred years.

So, it is advisable to place a router taking into account the aforementioned factors. That is, it is necessary to put it so that between him and clients were smaller obstacles, and the obstacles themselves have affected the signal as little as possible. Well, and so that there is no sources of interference. In addition, it is worth paying attention to the orientation of the device and antennas - a typical location is usually drawn in the user manual. As a rule, the same external antennas must be stretched vertically. Finally, another one important moment - Routers have a property to heat up during operation, so that there are no need to place them next to heating and other heating fixtures. Be sure to follow the normal ventilation of the device. No, it is not necessary to start a separate fan for him, but the air flow should always be: the housings are not just done "holes".

Update software and firmware

To update the firmware and driver for all devices, it is worth:

• use the built-in OS mechanisms;
• go to the manufacturer's website, find, and then install latest versions BY.

From the general advice on the placement of the router, we turn to more practical. And the first will be the most obvious, but for some reason they regularly forget: Update on all devices! Seriously, decent manufacturers update the drivers and firmware is not just like that. We won't call this phenomenon in any way, but still the developers really if they do not drastically improve the operation of the devices, then at least make adjustments. For example, update the parameters for compliance with the rules of individual countries and regions that have a property regularly change. And in general, it has already been said many times that any complex modern device is in many ways, and not at all "iron".

For smartphones, tablets and other mobile devices, there are usually built-in firmware update systems. In the extreme case on official sites, they also laid out - along with enough detailed instructionswhich must be strictly followed. The same applies to the routers themselves - for them is most important to have the most fresher by. MacOS users are not particularly worried about what is all fresh drivers For native adapters come with updates itself. And even old challenge With Wi-Fi in Apple finally won. Linux users are generally unclear why this material read. For Windows options some. If it is a laptop or branded PC, that is, it makes sense to go to the manufacturer's website and search for fresh drivers in the download or support section.

If there is nothing on the site or it independent assembly, you will have to tinker a little, finding out exactly what Wi-Fi adapter is installed in the system. In Windows 7, you will have to go to the section "Control Panel \\ Network and Internet \\ Network Management Center and Sharing \\ Adapter Parameters Changes." In Windows 10, the path is the same, only in the "Start" menu, it is predefined to find the so-called classic control panel (you can simply start typing from the keyboard this name directly to the menu). In the opening section, all network adapters will be shown. We need an active wireless adapter, who has a non-gray icon and without a cross in the corner, if you are already connected to home Wi-Fi. When double-clicking on the adapter icon, a window will open with its status, where you need to click on the "Properties" button. The top will be the full name of the adapter.

Next, too, there are two ways. Or try to find fresh drivers - they are usually given in the form of a finished installer - on the site of the manufacturer of the adapter, but they generally speaking, not always there. If there are no there, it is better not to unconvent on all sorts of informal sites, and use the built-in in Windows update Drivers. In the same window, it is enough to click on the "Configure ..." button right under the adapter and in the new window go to the Driver tab, where, in turn, click the "Update ..." button. And there it is already clear that you need to choose automatic search. If you are afraid that something goes wrong, then before making all operations in the OS, you can make a recovery point according to the instructions for Windows 7 or. If all this has not improved the situation with the home wireless network, there is nothing to do - you have to refer to the settings of the router itself.

Channel selection and changeWi-Fi

To select suitable Wi-Fi settings, it will be necessary:

• use Wi-Fi an analyzer and choose the most far away from the adjacent channel;
• remember that for 2.4 GHz there are only three non-passing channels for the standard channel width and only two for the extended;
• know that for 5 GHz is most likely, only channels from the 36th to the 48th are suitable;
• touch the function of the Band Steering function, if there is something, and if necessary, turn it off.

It has already been noted that the router always scans the state of the ether around him. Why does he do it? We'll have to go deep into the theory. Previously, again, it was noted that there are allocated radio frequency bands. For better use They are divided into separate pieces, which are called channels. Depending on the region and the country, the rules of their use may vary, therefore it is important that the region has the same in the settings of both router and other devices. Sometimes it is determined by indirect features like the keyboard layouts, the interface language, time zone, the parameters of the adjacent Wi-Fi networks and so on. In the range of 2.4 GHz, there are 13 pieces such channels, but the work of Wi-Fi on any of them affects the adjacent channels too. In fact, the channels do not interfere with each other in five each other: 1, 6 and 11. Worse, it is quite acceptable and such a distribution: 1/4/7/11 or 1/5/9/13. If we are talking about more modern standards with a double channel width (40 MHz instead of 20 MHz), then there is no place for this place: without intersections, for example, only the 3rd and 11th channels will work.

What does all this mean in practice? But what - only in modern routers a relatively recently appeared the function of the dynamic selection of the Wi-Fi channel, depending on what other wireless networks are near and what channels they occupy. The idea is to choose such a channel for your Wi-Fi, which would further defend from those that are around. If there is such a function in the router, it is definitely to turn it on. Somewhere you can even choose the interval, it is often enough to change the channel once a day. And if there is no such function, you will have to make a choice of channel manually. There are many utilities for this. Windows users can use Inssider Lite, Acrylic Wi-Fi Home, LizardSystems Wi-Fi Scanner. For Mac OS X there is WiFi Explorer Lite, Airradar. Android has good free WiFi Analyzer analyzers and. But for iOS apple Once it has forbidden such utilities, so there are no direct analogues, but if you found something worthy, share in the comments.

The interface in all such utilities is about the same. You can view the list of Wi-Fi channels in neighbors and on the chart to see their signal level, as well as how many channels overlap nearby wireless networks. The signal level is indicated in negative numbers - the closer such a number to zero, the signal is stronger. For conventional 20 MHz width channels, it is simply shown its number, and for channels for 40 MHz, the numbers of two channels of 20 MHz are actually indicated, which are used. At the same time, such utilities show which neighbors work on the same channel as yours, and which channels overlap - and the other can interfere with Wi-Fi work. What about all this information to do? Everything is simple: in the settings of your router, it is necessary to set a channel that would have defended on all from neighboring networks and by number, and according to the signal strength.

In the range of 5 GHz, the principles of the same, only available channels here more, and they themselves are sewn (80 MHz or 80 + 80/160 MHz). All of them are broken into two large blocks: from the 36th to the 64th and from the 100th to the 165th Channels. Formally, all of them are permitted in the Russian Federation, but in fact even able to work with the second device channels can not be seen. Yes, yes, this is one of the main reasons why it is worth updating by. The top block is usually cleaner, that is, there are less neighbor Wi-Fi, but they will have to check each client separately on the subject of whether it can connect to home Wi-Fi. In addition, there is another nuance concerning regulation relative to the power and protection against the creation of interference for various third-party equipment. If you do not go into details, then all channels above the 48th can work worse than the rest.

In modern dual-band routers, a function is increasingly found, which is called Band Steering, Dual-Band Wi-Fi, Smart Connect or anything in such a spirit. Its essence is that the router automatically "pushes" customers into the range that it considers most preferred at the moment. Usually mandatory condition To work this technology is the same name. wi-Fi network For both ranges, so it is possible to disable it simply by renaming the network of one of the ranges. There is no single standard for this technology, and it works very differently. Optimal option, perhaps, it is worth considering the preferred connection to the 5-GHz network. Well, if nothing good is this technology in the work of home Wi-Fi does not introduce, you can turn it off.

Additional settings

What else can you do:

• abandon old devices with support only Wi-Fi 802.11b or 802.11g;
• choose right mode wi-Fi works, that is, 802.11n or 802.11g / n for 2.4 GHz and 802.11n or 802.11n / AC for 5 GHz;
• leave the auto battery of the channel's width, that is, 20/40 MHz for 2.4 GHz and 20/40/80 or 20/40/80/160 MHz for 5 GHz;
• try to disable non-standard additional Wi-Fi acceleration technologies;
• try slightly reduce the power of the radio module Wi-Fi;
• on mobile devices, disable access to 3G / 4G networks when in the Wi-Fi coating zone;
• check the power saving modes of devices and adapters.

Now there are two modern Wi-Fi Standards: 802.11n (2.4 GHz and 5 GHz) and 802.11ac (5 GHz). However, users can also have old devices that support, for example, only 802.11g, and even the ancient modern standards standard 802.11b or even 802.11a. The latter, however, is now very difficult to find, but if they suddenly have it, then it is best to completely refuse them (and if the router only supports 802.11b / g, then it is necessary to throw it out), since they can slow down significantly Wi-Fi work. Why? Because the router always tries to organize a connection, providing the most common opportunities for all clients, from which old devices can be comfortable, and new - not very. If there are 802.11g devices and you can also refuse them, then it is better to do so. In some models, routers have special settings that in theory allow old devices to connect so that they do not interfere with the new, but they do not always work correctly. The type of supported standard can be found in the description of the device or its wireless adapter.

So, for the range of 2.4 GHz, the 802.11n (only) operation mode is most preferable, 802.11g / N mode follows. For 5 GHz there is only one optimal option: 802.11n / AC. With the width of the channels, the situation is this: according to the rules, the router should understand and make all devices that meet the standard. So in the settings it is necessary to choose the option of 20/40 MHz (for 2.4 GHz) and 20/40/80 or 20/40/80/160 MHz (for 5 GHz). Some routers allow forcibly setting the maximum possible width of the channel. Yes, it sometimes helps to squeeze all the juices from wireless connectionBut not always and not for all devices. Moreover, if only stability is important, that is, it makes sense, on the contrary, to reduce the width of the canal. Similar settings can be checked on the side of the adapter by doing the same steps as in the driver update section, but by selecting the "Advanced" tab at the end. However, in these settings, such a variation of the names of the parameters is usually, which is better to be very accurately changed any of them, and if there is no confidence, it is not touching at all.

In routers there are more additional featureswhich is also worth paying attention to. Various "accelerators" can deliver a lot of headaches, as it is almost always technologies overlooking the standard. For old devices there are XPress or TXBurst functions, and in the new there is Turboqam / 256-QAM or NitroQam / 1024-QAM. BEAMForming technology (beam formation), usually available in Explicit formats (new devices) or implicit (old devices), as well as all of the above, can improve the work of some clients, but to harm others. About MU-MIMO can still not remember much, this technology on customers is still not available. However, it is possible to experiment with these settings, including / turning off them and watching the behavior of client devices. It is exactly necessary to leave the WMM option enabled, but with various systems Classification (QoS) and restrictions (shaping) will also have to check out different scenarios or turn off the us.

There is one more - absolutely contrintedient - setting relating to the power of the radio transmitter. You can usually either specify the power in the militates, or select / specify the power level as a percentage of the maximum. So, the maximum power is not always good! Without going into details, let's say that the decline, on the contrary, can significantly improve the quality of communication. To begin with, you can try to throw off the percentage of 15-25 - and see what will happen. Exactly the same story and external antennas that have a higher gain (which is not always true) and other "enhancements" Wi-Fi like self-made or purchased reflectors - they can harm. If you have a good relationship with your neighbors, then you can also set up non-changing channels for them, reduce the power and properly place the router - help others, and yourself.

Finally, for smartphones, tablets and other mobile devices there are also a couple of very simple actions. First, when you get into the Wi-Fi zone, you should disable access to mobile Internet, as well as options like Wi-Fi Assist (Help with Wi-Fi) in iOS. Secondly, everywhere it makes sense to check the settings of energy saving both for OS as a whole and for themselves wireless adapters. Both can affect the consistency of connecting to home Wi-Fi.

Conclusion

Finally, another simple but important Council: If you are not sure about your abilities, it is better not to be bother. And if you are afraid to forget what and where they changed, then use the function reserve copy and restore settings that are practically in any modern router. However, here are far from all and far from the most difficult for the setup setup, and experts may not even agree with some advice. Nevertheless, if none of the recommendations individually (or all together) did not help, then either they are not applicable to your situation, or it is really time to take care of the purchase of a new router, and even additional access points. We hope that it does not threaten you!

Amenities when used wireless technology Provided the distribution of gadgets in which WiFi integrated. Of course, traditional LAN ports do not lose their relevance, but already as a minor means of entering the network. Especially since on the street or in a public place, this port will not be required at all. However, the use of wireless access tools to the Internet has its drawbacks in the form of interference or insufficient coverage area. Therefore, a question arises about the means, at the expense of which it is possible to strengthen the WiFi antenna for its more efficient operation.

First of all, users appeal to equipment manufacturers, which note the dependence of the quality of reception from factors such as radius network security, Access point type, as well as the characteristics of the antennas themselves. Of course, the listed factors directly affect the quality of the signal, but if they do not allow to achieve the required quality of communication, it is not necessary to despair - there are many ways to solve this problem.

Proper location of the device

Before interfere with the settings and experiment with the modernization of devices, it is worth analyzing the location of the device in terms of optimal reception. First of all, it is necessary to consider that the access point should ensure the maximum possible coverage of the potentially used area - for example, in the office or apartment.

Also in response to the question of how to enhance the antenna, the WiFi-router signal and the overall quality of the reception, it should be noted the importance of free space for radio waves. That is, interior partitions protrude with a rather serious barrier and may make it difficult to broadcast the signal. Moreover, it concerns modern cellularly concrete walls with drywall trim, and even more brick reinforced facilities. It is possible to solve the problem by choosing such a point for the location of the router so that unhindered access is provided.

Channel Frequency Coincidence - What to do?

Software strengthening methods, unfortunately, the least popular with users, while the settings depends a lot. Start work improvement wireless devices At the program level it follows from the analysis of the frequencies on which the equipment functions. For example, if there are 10-15 networks in the house, it is obvious that good quality will have to forget, since with a greater probability the signals intersect and interfere with each other.

If you correctly choose a channel broadcast channel, then all questions about how to strengthen antenna WIFI.-Rueter, will disappear by themselves. But to select the channel you will need special program - For example, you can use the Inssider system. Use it is necessary in parallel with the WiFi adapter. INSSIDER installed on the computer will display data about all available channels, Introducing busy and free. In accordance with the information received, it remains only to reconfigure the mode of operation of the adapter to the appropriate frequency.

Increase the power of router

The unsatisfactory signal reception signal may be associated with the fact that the settings themselves impose restrictions on it. Actually, this is an elementary way to improve the quality of work on the network. To understand how to strengthen the power of the WiFi-Router antenna, you need to deal with the settings specific model Devices. Typically, the power adjustment is present in "Extended Settings", on which the network operation parameters depend.

In one of the tabs should be an inscription with reference to the transmission power. For example, on english language It may be the Wireless Transmit Power string. The adjustment indicator itself can be presented in different ways, in percent or levels of type "low", "high", etc. Thus, to obtain high power of the router and enhance the WiFi antenna, you should install maximum value This parameter. True, in SOHO-level modifications, such settings may be absent, and then only a special firmware will help, to integrate which it is advisable to contact professionals.

Configure according to standard and range

Again, many users are not familiar with the standard on which their device works. At the same time, two network standards are relevant to date: 802,11AC and 802.11n. The first is still unavailable in a wide circle consumers, and the second is considered one of the most powerful. If you plan to strengthen the WiFi antenna due to the fact that the device does not perceive the signal at all, then it is possible that the equipment is elementary operating on another standard.

The transfer of the gadget to the 802.11n format is usually performed in the main settings - in essence, this is the choice of parameters of the operation mode. It is also worth mentioning about 5 GHz, with which devices that support the 802.11n standard are operating. Unlike a more common range of 2.4 GHz, 5 GHz channels are still more or less free and not littered, therefore, the quality of work in this format is much higher.

Disable energy saving mode

When operating modern computers Economy saving issues have become particularly relevant. Mainly it applies to portable deviceswhich should work for a long time without charge. Unfortunately, only subject to increasing performance, you can strengthen the reception of WiFi on the tablet.

The antenna will work with minimal power settings if the device is switched to the energy consumption mode. This does not mean that it is necessary to install the most productive format of the computer, but the minimum level of power supply is better to avoid. The optimal option is to use a balanced mode that will not prevent full-fledged WiFi operation.

Disability antenna

This is a favorite way to improve the quality of reception of different antennas among folk craftsmen. Its essence lies in the fact that the working element of the reception is additionally equipped with metal devices in the form of foil pieces, tin elements and cans. Since it is possible to strengthen this scheme without harm to the device itself, it makes sense to experiment with different designs. Although some users note a good effect from such modifications, it is not worth waiting for a serious result. At least this method of solving the problem significantly loses the elementary replacement of the antenna to a more powerful model. Nevertheless, the coverage area when using metal supplements should increase.

Application of repeater

Installing a WiFi repeater is also installed to directly gain the power of the signal. The principle of operation of this unit is that it is included in the network as a regular client, but in the future plays the role of a distribution of the received signal, expanding the coating in accordance with the possibilities of its antenna. By sizes, the repeater is identical to the standard power supply, so much space does not take. Also its acquisition is beneficial in terms of simple settings and maintenance in general.

Using the repeater, you can not only enhance the WiFi antenna signal, but also to extend the coating using WDS technology. That is, the device will allow you to merge different access points without the need to use wired contacts. The cost of budget models of repeaters varies on average from 700 to 1000 rubles. More productive and reliable devices with advanced functionality can cost 2000-3000 rubles.

Extension cords for adapters

To save yourself from problems with receiving a signal via WiFi, it is recommended to initially acquire powerful adapters and, most importantly, with an external antenna. In this regard, the model of receivers integrated into tablets and laptops is less effective. However, for such devices it will not be superfluous to provide an extension. With it, you can move the modem in search of the optimal place to receive. If there is a question about how to strengthen WiFi antenna on a laptop, then this option will be even more advantageous, since the mobility of the device itself will expand the ability to search for the best location point. By the way, the length of the cables for USB devices can be up to 3 m.

Conclusion

It is rare to significantly improve the quality of the WiFi signal reception due to the use of one or even two ways. The fact is that the execution of all recommendations can be reduced to no if, for example, the minimum power level is indicated in the device settings. And vice versa, if all program parameters are focused on the optimal mode of operation of the equipment, the intercourse in the form of a interior partition will also spoil potentially high quality reception. Therefore, it is possible to significantly enhance the WiFi antenna only with an integrated approach to the analysis of its settings and the location assessment. As practice shows, the most effective decision In terms of enhancing the power of reception, it is still the purchase of more technological modern equipment. In particular, latest models Opening the possibilities of working in new providing high and stable data transmission.

Instruction

First, try to enhance the reception of the Wi-Fi signal. It is better without technical intervention. Disable the functions that allow you to enable the economical mode of operation of the adapter. Open the Control Panel menu and go to "System and Security". Now find and open the "Power" menu. Select the plan that you use while connecting to wireless access points.

Click "Setting the Power Plan" button. Now select Change Advanced Power Parameters. Find the Wireless Adapter menu and deploy it. Now open the Main Saving Mode. Select the option " Maximum performance"When working from a battery and from the network. Save the power settings.

Now try to increase the power of the Wi-Fi router. Naturally, the easiest and most logical way is to purchase a more powerful device. Unfortunately, this approach requires large financial costs. Therefore, start with the acquisition of a better antenna. Most routers have their own antennas that are easy to remove.

Examine the type of antenna fastening to equipment. Purchase a device with a similar fastening and connect it to the router. If the result received did not suit you, then try using the screwdriver to enhance the signal. Turn the top of the antenna to be able to connect the wire with it.

Take a piece of metal cable and solder it to the bare part of the antenna. The second end is connected with the computer system unit. In this case, it is better to connect to the rear of the block so that the signal spread into the side opposite from the wall. As an alternative, the system unit can be used metal curtains.

The quality of the television and radio signal does not always suit the audience and listeners. Moreover, interference may even be when there is a powerful antenna. In order to improve quality reception, the antenna needs to be adjusted correctly.

You will need

• coaxial cable, portable radio stations or mobile phones.

Instruction

If an antenna is directed, try reinstalling it so that there is no obstacles between it and the source of the signal. Such obstacles can be high-rise buildings or other structures, power lines and so on. You can try exactly the direction to the signal source. To do this, you can use the help of an observer controlling the signal at the receiver. To communicate with it, you can apply portable radio stations or.

If you have a plane polarization antenna (type "Wave Channel" and the like), check the polarization of the received signal. Adjust it according to the data obtained. To do this, you need to rotate the antenna relative to the axis aimed at the signal source. Most often enough just try turning the antenna by 90 °.

Efficiency antennas You can increase due to an antenna amplifier. But in this case, the gain limit is set to the level of interference. To reduce their level, use the shielded reduction, that is, the antenna is best with coaxial cable.

Efficiency antennasEspecially when taking long, medium and short waves, you can increase by installing additional grounding. It should also be borne in mind that the antenna must be consistent with the input chain of the radio. That is, it is necessary to connect it to the type and cable, which are recommended in the instructions for the receiver or.

note

The antennas of long, medium and short waves can be a length of long-length wires. The suspension points of such antennas are also recommended to be installed, based on the greatest volume of receiving the desired stations. That is, it is necessary to change the position of the antenna.

Helpful advice

If we are talking about room antenna, then the best solution There will be a stationary outer antenna. This will dramatically increase the quality of the reception. Also K. external antenna It is recommended to connect portable mobile receivers and TVs during their operation in stationary conditions.

The coverage area of \u200b\u200bthe Yota provider is much less than that of the operators cellular communication. Subscriber who lives on the border of the area of \u200b\u200bconfident receptionYou have to take measures to increase the signal level at the modem input.

Instruction

Do not attempt to connect any amplifiers to the modem. The output power of any wireless equipment, including 4G (WiMAX) standards, is limited. In addition, the amplifier can create an uncommon radiation on harmonics, which is also a violation.

Radio waves at the frequencies used for data transmission in the Yota network are delayed capable of conducting a current. In the house whose walls are reinforced concrete, it makes sense to bring the laptop along with the modem to the window. Even if it does not enter the base station, the signal level may increase. You can simply be like a laptop around the room - due to the presence of interference maxima and lows of the point with a high signal level may be anywhere.

Move the laptop to search for places of confident reception It is not always convenient, and if the computer is stationary, especially. The problem will solve the extension cord, which allows you to attribute a modem from a USB port to a distance of 2.5 meters. It must comply with USB 2.0 specification, otherwise the data transfer rate will decrease. Move the modem slowly because updating information about quality reception happens with a delay.

For focusing ultrahigh-frequency radio waves, parabolic mirrors can be used, similar to that apply in satellite antennas. Best results provide reflectors from such receiving devices. Modem Place in the focus of the mirror instead of the converter. Surrogate reflectors can also be used in the form of conventional metal pelvis, including painted. It is impossible to place the modem outside the room, since it is not hermetic. Place the whole design will have to right in the room. Antenna must be directed to the nearest basic station Yota network. If you do not know where it is, pick up the best direction by experienced.

Install and configure Wi-Fi router in your own apartment is no difficulty. But sometimes it is not enough, because there is not enough standard wireless access area coverage.

You will need

• metal wire, soldering iron.

Instruction

For amplification signal Wi-Fi There are several proven methods. Some of them require the acquisition of additional equipment, other - technical intervention in separate details of the device.

Let's consider gain signal Wi-Fi router, change it. You can simply purchase a similar device of another format. If you carefully examine the structure of the router, you will see: attached to the device through the threaded sleeve, i.e. It is not difficult to replace it.

If it is necessary to significantly increase the range signalThe existing antenna will have. Release its upper part of the insulating layer. Sold down to the open part of the antenna metallic wire. Otherwise, pull it out on open space.

If this was not enough, then solder the free end of the wire to the room television, having previously turned off the latest from other devices.

Connect between both Wi-Fi router with a network cable. Connect it to one end to port LAN That device that you have already been installed, and the other to the Internet (WAN) port of the second equipment.

Open the second router settings and create a wireless access point with parameters similar to the first network. In settings network connection To the Internet, select the type of transfer signal WAN.

Be sure to turn on dHCP feature in settings local network The first Wi-Fi router. If you are all done correctly, the laptops connected to any of two wireless will be able to access the Internet.

Tired of low speed of the Internet, but do not know how to strengthen the Wi-Fi signal? Use simple advice By setting up and installing equipment to bring the speed of the Internet to the fact that the provider is declared.

Low signal is not necessarily associated with network problems and technical work provider. The speed of the Internet can affect the settings and location of the router, working in the house of electronics, especially light garlands and microwaves. To enhance the Wi-Fi signal, it suffices to follow the following recommendations.

Update your router. The ability of the device over time could be outraged, which means that the reception and signal transmission indicators will be lower than the provider declared.

Change the location of the router. The higher the device will be installed, the stronger the signal you will receive. It is not necessary to place a router on the floor, behind the carrier or insulated wall, a metal door or in the far corner from the computer. Try to remove the router away from the electrocable. You will not be able to strengthen the Wi-Fi signal, if an aquarium is standing on the way to the router, a large mirror, a wardrobe with glass shelves or doors, a mirror, and halogen lamps will be used as lighting.

Change the frequency of the router, and you immediately notice strengthen Wi-Fi Signal. To do this, choose instead of 2.4 GHz frequency of 5 GHz. So you will reduce the effect of all electronics on the speed of the Internet. This is especially important if you are constantly turned on the nanny radio, it works, video surveillance is conducted or you often use Bluetooth.

Do not forget to update the software on your computer, and smartphones. Developers try to improve the performance of devices, including when working with a wireless network.

Repeators can become an effective Wi-Fi amplifier. For this, routers that you used before that can also be used. It is enough to update the antenna in such a router and use it as a repeater.

If you have a common router with neighbors in your house, you can configure Quality of Service (QoS), setting a certain priority for traffic. This is relevant if your neighbors of streamers, gamers or families with several children. Without configuring a guilty, they will take most of the speed on themselves.

Change the network security protocol on WPA / WPA2 instead of WEP or limit the number of possible gadgets for simultaneous connection. If you have a tick on the Enable SSID Broadcas point in the router wireless settings, it is better to remove it. So you can hide your Wi-Fi. Do not forget to set a password to your network.

Many users also wind up the rear case of the router and put shields from metal items for it. In some cases, this method allows you to strengthen the Wi-Fi signal without any additional settings.

A huge number of users refused wired Internet in favor wi-Fi technologies. Even some computer owners prefer to use a Wi-Fi adapter to get rid of network cables.

You will need

• room antenna, USB extension cord.

Instruction

There are several ways to improve Wi-Fi quality. This applies not only to routers, but also the equipment that takes. The fact is that the majority Wi-Fi routers And the devices such as them have a very scanty coverage area. Sometimes it lacks even at the house of medium sizes.

If you need to provide a high-quality signal on a large area, it is reasonable to use several routers to achieve this goal. They can be combined with each other, having achieved the creation of several access points. At the same time, you will still use only one cable with the Internet.

If a this option You are not satisfied, try to increase the Wi-Fi adapter coverage area. To do this, replace its antenna (antennas). Find a better quality equivalent or reinforcing the antenna yourself. Pick the equipment with which you will increase the antenna. For these purposes, both ordinary wires and a small room antenna are suitable.

Ideally, you need to use the antenna "". Remove part of the protective layer of the router antenna. Sleep the metal wire to the bare part. The second end is close to the room antenna lattice. This method allows to increase the signal by 20-30%. At the same time, you have the ability to hide the Wi-Fi router without losing the quality of the signal.

If you wish to strengthen the Wi-Fi USB adapter, you will need an extension. Most often system blocks Clean the table or remove into hard-to-reach places. Naturally, receptionand the signal in such places will not be the best. Purchase a USB extension of the desired size. Connect it and stick to it Wi-Fi. Place the adapter on the open space, for example, put it on the table.

In any country there are our folk craftsmen, inventors and just inventors. It would seem that to improve reception The signal Wi-Fi equipment will need to buy the appropriate equipment or move to the best places. reception Signal, but you can strengthen the quality of the signal to be with screwdrivers. No need to run to the economic store behind these materials, most likely they have at home.
