Strengthen the wi fi antenna signal. Improved receiving a Wi-Fi Router signal with your own hands

The performance of the Wi-Fi network delivers inconvenience in two cases. The first: weak and unstable. Second: Low data transfer rate. Both are solved easily even by a man with a humanitarian warehouse of the mind if he read our article or put a beer drawer to a neighbor.

An option with beer is definitely better and makes a revival in the Russian economy, and also gives a tangible GDP growth. But this option often has an incorrigible disadvantage: the neighbor may not exist. And then the will will have to read that we have been imagined here.

The most important thing. Clean that in the center of your Wi-Fi-network there is a modern full-fledged wireless router (Aka router). Keyword - Modern. The fact is that communication equipment develops as actively as the entire IT industry. Those standards, protocols and speeds wireless transmissionThat was the norm 5-7 years ago, now hopelessly behind. For example, not so long ago, the channel of 50-60 Mbit / s was considered a decent option for the house, for the family, for Ponte. And now inexpensive devices in a couple of thousand rubles declare theoretical 300 Mbps.

In his personal diaries, the captain clearly noted that the main obstacle to wi-Fi signal are walls and partitions. In addition to the walls, any shielding obstacle with a metal content may become a serious interference for a Wi-Fi signal - most often this mirror, aquarium or steel statue of Darth Vader. The demolition of all walls in the apartment is the optimal solution to all your problems, but it is troublesome, yes. It is easier to think about finding the optimal point of placement for the signal source. Your wireless router should be as closer to the center of the room and do not lie on the floor, and accommodate at least in the meter from the floor.

Launcing network search, you probably noticed that in your apartment there are still a couple-triple, and then a dozen of foreign Wi-Fi signals. Few people for some reason think about the fact that other people's networks work in the same frequency range as yours, and there is nothing good. According to standards, in Russia for wi-Fi works-set selected 13 frequency channels. We raised from the instructions for the popular ZyXEL KEENETIC router Lite Screenshot The configuration menu - it can be seen as in the "network client" router shows the channels engaged in neighbors. There are also individual programs that make the same thing, such as Inssider. You can only explore the resulting list, select the most free of 13 channels and set it the default router.

Many craftsmen manually pump up the antennas of routers, hanging tin on them, foil and so on. In fact, the game is clearly not worth the candle - it is better to buy a suitable high-power antenna. A considerable range of them on Wi-Fi equipment sites, and some look very exotic. The reinforcement coefficient of antenna is indicated in isotropic decibels (DBI). The standard antenna from the home router has a power around 2 DBI, but to find and buy an antenna with a gain of 10-20 dBi does not represent problems, and the situation with the availability of the signal is solved radical! But Foil also makes sense to tame - recently there was a particularly virtuoso lifehak with reflectors from the increasing interest.

Many modern models of routers are completed with a pair of antennas, and in the top models there may be even more. Usually it provides a good signal, but if not, then you will immediately change two antennas. In such a situation, it is better to put an additional point of signal distribution in the apartment - such devices are called "repeater" (Wi-Fi repeater). They cost approximately as an inexpensive router and runner in the settings.

Often a problem element in home network It is not a router, not layout of the apartment, but the receiving device itself. It is necessary to bore two things on my nose forever. First: If you have a powerful computer for games and multimedia, it is better to still connect it to a wire with a wired connection (a million reasons, and all of them are important). Second: if you're going to take Wi-Fi through the adapter, choose a not tiny device with margins (it is suitable only for gatherings in the coffee shop), and a receiver with a big antenna. Buying a Wi-Fi adapter with an adapter antenna helps and then when your laptop catches a pair signal, but in some kind of corner the room is much better. You can plug in the laptop Wi-Fi adapter, and place an antenna from it in that very happy corner.

Sometimes it happens that if there is wireless network In a building of 2-3 floors, WiFi signal does not reach some rooms, or there is a signal, but the connection speed is weak. One of the reasons why this may occur is incorrectly selected WiFi antenna for a router.

WiFi is a technology that works well only on "direct visibility". Any barriers in the form of walls, cabinets, mirrors and other very badly affect the distribution of the wireless signal. Therefore, a comfortable work on the network will depend on the rational choice of antenna for the router.

What are WIFI antennas

All WiFi antennas can be divided into two types: directed or omnidirectional antennas, which, in turn, are internal and external.

Omnidirectional antennas

The class of these antennas is the main to build wireless networks. The bulk of "home" routers is equipped with these antennas. They evenly distribute WiFi signal throughout the radius of their action. Basically, the omnidirectional antennas represent an ordinary pin, spreading the WiFi signal in the plane perpendicular to its own axis.

Option of an internal omnidirectional antenna

Please note - omnidirectional antennas must be installed only vertically. Then the propagation of the signal will occur in the correct manner, and the distribution area of \u200b\u200bthe wireless network will be maximum.

Sometimes it happens that you need to cover the wireless network with a large territory, for example, a production facility. Then the outer omnidirectional antenna is established on the central building, which has an amplification coefficient of 8 dB. Such an antenna is capable of transferring a WiFi signal within a radius of 600 meters at a rate of 54 Mbps and 1800 meters at a speed of 1 Mbps.

Option of outdoor omnidirectional antennas

Directional antennas

This antennas class is used to organize the WIFI network by the point-to-point type. Those. They work well if you need to connect, only with one access point or one computer.

Description of the directional antenna

Inside the building, antenna is able to "break through" impassable walls for WiFi Signal. A good option will be the use of a directional panel type antenna. This antenna is a flat rectangle that can emit radio waves in one direction. In this case, the gain can reach up to 6 dB.

Option of an internal directional antenna

But if you need to transfer the signal, for example, to the next house, then you can apply the outer antenna of the cylindrical shape. It is installed horizontally and heads towards the place where the receiver is located. With the help of such an antenna, you can achieve an amplification coefficient up to 18 dB.

Option of the outer directional antenna

If suddenly you are not quite sure where you need to position your antenna, you can use a universal directed option. This type of antenna is suitable for both internal installation and outdoor. The gain of about 8 dB.

Option of universal directional antenna

Principles of Placing WiFi Antenna

The power of WiFi antenna is influenced by many factors.

If the antenna is omnidirectional, then it is necessary to place it in the center of the building.
Antenna or router itself is better installed above the furniture level.
Check the router firmware, it must have the latest version.
It will be nice if the antenna will be located far from the windows, mirrors and steel structures.

Connecting the router to the external antenna and its setup

For example, selected router Mikrotik RV751U-2ND.

Connecting an external antenna

We take a router, and on the rear panel we are looking for the MMCX connector.

MMSX connector

To connect an external antenna you will need a special adapter that connects your router with an antenna. Usually these adapters have small size, approximately 20 cm, so they can be used two or three. One adapter can be purchased, but long. Now we produce the connection, as shown in the figure below.

Antenna connection option

After performing the physical connection of the router with the antenna, it must be configured to "see it".

Setting the router to work with an external antenna

Winbox utility is used to configure the router. Run it on your computer connected to the router and in the Connote field to select your router.

Selection of router

To include on the use of external antenna, we carry out the following actions:

Open the Wireless menu.
In the menu - Interface go to the NT tab.
From the list of Antenna Mode, specify the version of the work - Antenna b.
Click - approx.

Setting up router

After executing the settings, the external antenna should work in parallel with the internal one. Suddenly you want to work one external antenna, then remove the checkboxes from the field - chain0, and leave the chain1. Do not forget to harm - Apply, to save the settings.

An example of setting up an external antenna

Setting the power of the transmitter

In this router, there is an opportunity to programmatically configure the power level of the Wi-Fi transmitter. This feature can be useful if you need to transmit a signal from an external antenna for a long distance.

To adjust the power, perform the following actions:

Open the Wireless menu.
B Wireless Tables Indicate the WLAN1 Wi-Fi interface.
In the Interface menu, press the button - ADVANCED MODE.
Select the tab ..., and there the TX Power item.

Setting the power of the transmitter

In the window that appears, you can configure the transmitter power. In TX Power Mode, you can select the power setting mode, and in TX Power specify the power itself.

Selection of power installation modes

Types of installation modes:

Default - In this mode, the power is selected from the table located in the memory of the router.
card Rates - power selection mode by a special algorithm using the power value specified by the user.
Manual - here you can set your power for each speed.
all Rates Fixed - At all speeds, the power is the same, the user specifies it.

Strengthen the WIFI signal simply and easy

We are all familiar with such concepts as the Internet and Wi-Fi, almost everyone knows how to enter the worldwide network and work there, having fun and do many other things. But few people know what is the directed Wi-Fi, how to organize it and configure. In this article we will tell you all the main points related to this topic.

The main types of antennas

Directional antennas - this is what helps us to install a directed Wi-Fi-signal. They are used to increase the transmission distance from the Wi-Fi router to the reception point.

Antennas for Wi-Fi are divided into two types - directed and omnidirectional. Each of them is necessary to obtain certain results. For example, take a directional antenna that concentrates the incoming and outgoing signals into one bar, which allows you to significantly increase the transmission distance and reception of the Wi-Fi signal. This kind of antenna is ideal for creating a Wi-Fi network, where information is needed to transfer information from one point to another. In other words, if you see or know that there is a directed antenna near you, you can try to install a Wi-Fi-bridge, mounted your directional antenna. The quality of the signal will be at a high level.

This is obtained due to the fact that the signal is concentrated in one thread. To make it easier for you to understand and manage the reception and signal transmission distance, some factors should be taken into account.

The first factor is Transmitter power. What it is higher, the more you can transmit your signal to the longer distance.
Second factor - Power Wi-Fi Antennas. It depends on the quality of the transmission and reception of signals.
Third factor - cable and its length. Consider that the larger the length, the worse there will be a signal, and vice versa.
Fourth factor - interference. It should be in advance to see what will stand on the path of your signal and whether he can break through them. The fewer obstacles and interference, the better the signal.

If you take the perfect example, which in life is practically unrealistic to meet, then 10 kilometers can pass from transmission before reception. In real life, this distance will be almost a half kilometer.

Unlike the first antenna, the omnidirectional distributes and receives a signal from all directions. Accordingly, the distance to which it can distribute and get a signal is shorter several times. If you take, again, the perfect example, then the maximum distance will be up to 1 kilometer, and in reality and less. But it should be understood and aware that the person who sets the omnidirectional antenna does not seek to distribute Wi-Fi on as much distance as possible, there is a completely different goal. This antenna is installed on the floors in offices, apartments, or on a whole building, if its structure allows the signal to be made through.

How to install an antenna at home?

If you install the antenna at home, then you need to know where your signal comes from. In the modern city, the signal is very easy to lose due to the fact that at home are very close to each other and can simply interrupt it or distort it. Each obstacle that occurs on the path from the signal can or partially skip it, or reflect, or not to miss it at all.

Take the following example. Suppose you have a router at your home, which works 500 meters of great visibility. You are from it through the wall. Knowing that a similar wall skips a signal by 15% after herself, we get a distance of 75 meters. In other words, the router will hand out the signal through the wall at a distance of 75 meters. But if you connect antenna to it, you can get rid of this problem.

To enhance the signal wi-Fi Router, you can use different ways, From the configuration of the wireless connection before installing a primitive reflector or purchase of the repeater. But before purchasing additional equipment or make reflecting screens, you need to figure out which factors affect the signal range.

From which the size of the coating zone depends

The transition range of Wi-Fi affects a number of factors:

Incorrect location of the router.
The presence of walls on the signal path, their material.
Interference from other devices running at the same frequency.
The number of wireless networks around.
The power of the antennas, etc.

For example, if you put a router to the farthest corner in the apartment, then the signal on the tablet through a pair of walls will be noticeably weaker than on a laptop that is in one room with a router. In addition, if the device detects many neighboring access points, this also affects the signal quality - wireless networks intersect, creating interference.

These shortcomings can be eliminated at home without special financial costsbut if you want a real increase in coverage zones, or you just have a big house in several floors, then best way Strengthen the signal will be acquiring a repeater. But first let's see what you can do without buying additional equipment.

Setting up router

If you purchased a router and found that it does not cope with the coating of an apartment or at home, then do not rush to go after another router or a Wi-Fi signal repeater. Try to configure the wireless network - for example, find a freer channel. The more wireless networks use one channel, the weaker the signal. Use the Inssider program to find the least loaded channel.

Run the program and click "Start Scanning".
Look, what channels are occupied by neighbors routers.

The channels are partially overlapping, so it will not work alone. But if everyone has a channel 1, and you put 8, then the impact will be minimal. To change the channel:

Open the router web interface in the browser (address, login and password should be listed on the housing).
Go to the main wi-Fi settings And specify the free channel number.

You can select 12 and 13 channels in the router interface, but if you want maximum compatibility with devices, then set a value from 1 to 11. Some devices do not support work with 12 and 13 channels, so, for example, on android wireless network will simply be detected .

Another way to strengthen the reception of the signal on the phone is to set the operation of 802.11n in the router settings. Most routers by default sets a mixed 11BGN Mixed mode, but if it is forced to be transformed into N, the coverage area and the speed of the Internet driven over the wireless network will increase.

Open the router interface in the browser. Go to the Wireless Settings section.
Select 802.11 N mode and save the configuration.

Unfortunately, there are also restrictions here too. Old devices do not support 802.11 N mode, so it will not be possible to detect the access point on them. In this case, you will have to set back the mixed mode of operation, which will negatively affect the signal quality. On some routers, you can additionally increase the transmission power. On D-Link it is done like this:

Open the web interface, go to advanced settings.
In the "Wi-Fi" field, go to additional settings.
Install TX power 100.

Usually by default and so maximum valueBut it is better to check this moment. On the routers asus And the TP-LINK order will be a bit different, but the essence is saved - you need to specify the maximum possible transmission power.

Using additional equipment

On YouTube, you can find different options for the design of amplifiers and reflectors that users make their own hands. The use of silver plated mirrors, foil and even cut tin cans. The principle of operation of the reflector is simple: the signal from the antenna does not disperse in all directions, but receives a specific direction.

But if you wish noticeably increase the coverage area, then you should think about the use of special equipment. You can offer three options:

Buying a new router working on a relatively free frequency of 5 GHz.
Acquisition of more powerful antennas (suitable if the router is removable external antennas).
Install Wi-Fi Repiiter.

The optimal option is to install the repeater, although the purchase of a new router is also a good idea. Replacing the antenna will work, but the effect will be less. In addition, really powerful antennas are not suiced, so it is more profitable to take a repeater or enhance the signal using another router operating in the repeater mode.

The repeater does not create a second network, but only enhances the signal from the router. Suppose the router is in the room, and in the kitchen the wireless network is not available. If you install the repeater in the middle of the path, the signal will enhance and the wireless network will appear in the kitchen.

Configuring the repeater usually does not cause questions and is simultaneously pressing the WPS buttons on both devices. It is important that you will not notice that the laptop or the phone is connected to the repeater, and not to the router: the network still remains alone, that is, you can safely install a local connection.

Optionally buy a repeater: if there is a second router, you can configure it to work in the repeater mode. Let's see how this is done, on the example of ASUS network equipment:

In the repeater mode, not all routers are able to work. But if there is a possibility in the interface to turn on the repeater mode, then there will be no problems with the coating of the premises with the wireless network, because the bunch of two devices will give a signal at all corners of the house.

Tips on how to strengthen the Wi-Fi network signal, modern Internet provides a huge set. But the disadvantage of many articles is that helpful information Hardened on the mountains of recommendations that are not related to a given problem or matter, but absolutely indirect. As a result, the user tries to increase the Wi-Fi signal area using settings that cannot be applied to solve such tasks. They are simply useless for the network, and even more so for the radius of its activity.

Updated and large instructions :.

The task of gaining a Wi-Fi network signal involves an effect on the change in the radius of its coating and the work distance Wi-Fi. You can often encounter a problem when it is impossible to use Wi-Fi in long beds, although the router is restored, and I have not been identified with its work. There may also be inconveniences if possible wireless data transmission on different floors of one room.

Factors affecting the territory of distribution of Wi-Fi signal

What is the radius of the Wi-Fi network depends?The answers to this seemingly simple question, there is a lot. An important role in the distribution area of \u200b\u200bWi-Fi is played by factors:

The number and power of the antennas of routers;
Wall thickness indoors;
number wireless Systems transmission data located in the neighborhood;
Location peripheral deviceproviding Internet access;
Other interferences.

Often, when purchasing a router, buyers are asked to choose such a device that will provide a stable signal for the dwelling with a different number of rooms or a private house. But it is impossible to advise something specific in such cases, since it is necessary to study many conditions. The area of \u200b\u200bthe room can be the only factor to pay attention to when buying a router. For an apartment with one room, the option of equipment is not quite suitable at a price having one antenna whose power is 3 DBI. To ensure the Wi-Fi network signal to the room with a fairly large area, you need to take into account other characteristics of the router. At the same time, the price factor should not be taken as the basis for the acquisition of the necessary equipment. For comparison, the device has a number of benefits: several antennas, a function to increase the radius of Wi-Fi activity from ASUS. But if it is used along with another model, less expensive, at the same distance, the result of its work is not largely different from the router model with a price smaller several times. Despite the fact that the last option is equipped with antennas located inside the device.

Changing equipment settings to increase wireless Wi-Fi signal strength

In the presence and installation of equipment for accessing the Internet in a residential, office space, you can try to independently affect the power of the wireless data network signal. The following tips will help you do. First you need to decide on how to solve the task:

Remower the router to enhance the signal
Resort to additional devices or devices

Search and Channel Change on Router

Step number 1: search and Channel Change on Router. The impact on the active work of your network can provide networks that are used by neighbors. They have a strong load on the channel, on which the operation of your network depends. Whether it can be found if the device installed in your room sees neighboring networks available for connecting.

Without experiments, do not do here. There are several action options in this case:

Set up any statistical channel
Select channel auto
Used additional program make a choice of free channel

What you choose must be consolidated in the settings of the data transfer device (router).

Square attention to the instructions on replacing and installing the frequency range in this article makes no sense. It is easiest to take advantage of the useful article. It contains information about the essence of the channel and the method of finding unloaded from them. For routers of various models, the frequency range varies according to a specific method.

Network translation in 802.11n

Step number 2: Transfer your network to 802.11n. The B / G / N mode (11BGN Mixed) is standard setting For the wireless network. For routers with an antenna number, more than one can be forcibly changing the choice in favor of 802.11n is characterized by the new advantages of the router: improved Wi-Fi broadcast, raising the speed and expansion of its operation.

In the opening tab find item Wireless network modeand set the command only in n mode ( N Only).

The described technique is clearly displayed below on the example of the ASUS router.

The step is completed by saving the setting and the full restart of the device. When problems are detected while connecting the router, it is necessary to return to the mixed mode of operation.

Checking power transmission

Step number 3: Check the transmission power in the router settings.The power of the Wi-Fi network can be set independently. Unfortunately, this possibility is not presented for all devices and serves to a greater extent to reduce power, but pay attention to this fact is still worth it.

For equipment from the manufacturer ASUS, you need to use the tab with the point Wireless network - professionally.In its lower part, the following is available: " TX POWER transmission power management.The power indicator is regulated by the measurement unit - percentage. It clearly has this kind:

For tP-LINK routers The change in parameters occurs with Wireless. — Wireless Advanced. To determine the parameters of the signal strength provided TRANSMIT POWER.Maximum power is indicated by the word HIGH.

Additional devices to increase the territory of active wireless network

Installation reputers, or setting up the second router in the amplifier mode.

This method differs from all others with its special reliability and efficiency. But, on a row with this requires additional material costs for the purchase of a repeater. This device enhances the signal and is installed in a place where Wi-Fi can still be caught, but its signal is already quite weak. It works on the principle of the repeater and transmits the network signal further. In the article, you can read in detail with this small device.

To perform the functions of the repeater, you can use additional routers from ZyXEL and ASUS manufacturers. It is possible to set the repeater mode, guided by the following techniques:

Change the router antennas to more powerful.

Using this method, the Wi-Fi network can be increased, but slightly. The result from the change of antennas is not effective. Moreover, as in the first case requires additional investments of funds. Yes, the price for removable antennas for the router is not so great, but is it worth spending money if it won't be any sense?

If you decide to change the antennas, you need to take the most powerful.

Buying a new router, transition to 5 GHz.

Since most routers operate at a frequency of 2.4 GHz., Then a device with a 5 GHz work range. It will be operated much more efficiently. This is explained by the comparative freedom of this range and the absence of numerous interference. As a result of this - an increase in the speed expansion of the radius of the wireless network.

To the transition to another range and purchase of a new router is resorted in the case when different other networks affect your network. Problems with low speed, permanent "glitches" and access lies to be resolved with the acquisition of a new expensive router with a 5 GHz work range.

Tip 1. Select the correct location of your router.It is worth using the Council, because most routers are installed either in remote premises or in the hallway. As a result efficient work Wireless network should not be expected.

The best location of the router will be the room in the center of your home or office, and you should also know that the walls interfere with the passage of the Wi-Fi network.

Tip 2. Homemade amplifiers For Wi-Fi antennas.The device can be done using sweater materials. For this, foil is suitable and tin. This is stated by many articles of folk craftsmen. In practice, you can put a foil or tin near the router so that the signal is cut off and changed the direction, but there is little effectiveness. Moreover, from aesthetic point of view, such a solution looks not very good.
