No WiFi connection. Internet Network Cable from Routher

We will analyze the problem situation when the phone is connected to Wi-Fi, but there is no Internet. It looks like this: next to the name wireless network writes "connected", but when trying to open any site in the browser, an error is issued Web-page is unavailable or 404 NOT FOUND. . Chrome in such cases still writes. The same applies to other software programs that use an Internet connection for their work or at least check updates when starting, will also issue an error of connecting to your web server.

In this article, we will tell you in detail how to solve the problem with the Internet on your computer, telephone or tablet. Read carefully, perform all the steps and you will definitely find the reason why you do not have an Internet connection when working Wi-Fi connection.

Problem collection

Before making any changes to wi-Fi settings Routher, computer or phone, find out the following points. It can simplify the search for the cause of the absence of the Internet or narrow the search for:

is the Internet paid and did the funds ended in the account?
is there any access to the Internet on a wire from a stationary computer?
is it possible to enter the Internet on Wi-Fi from other devices that use the same Wi-Fi router?
is there a problem with the Internet connection when connected to another Wi-Fi network?

Depending on the answers to these questions, you can already become more or less clear, which is most likely the problem is. For instance:

if there is no Internet at all - neither by wire or Wi-Fi, then the reason can be both blocking access on the side of the provider and the fault of the router. Next, we specify the provider, whether everything is in order with the line and the score, and then check the performance of the router.
if the Internet is on the PC on the wire, but there is no on any Wi-Fi device, the problem most likely lies in the settings of the router wireless network. The same output can be done if the Internet appears and works without problems as soon as you connect to another Wi-Fi network from the same device.
and if it turns out that on all devices, order, and only one there is no connection to the Internet, the problem is obviously in this "client".

Wi-Fi is connected, but the Internet does not work. What to do?

So, if you have a Wi-Fi is really "connected", but there is no Internet (Sites are not loaded, Skype and Viber does not connect, the laptop displays the yellow network icon with no access to the Internet, follow these steps to troubleshoot the problem. Steps are listed according to the probability factor.

1. Restart the router

Sometimes it happens inexplicable failure on router . Wherein the local network And Wi-Fi is working fine, but there is no access to the Internet. This can happen with very long-lasting operation of the router without rebooting and when changing the provider's network. Just in case: it is written how to restart D-Link remotely.

2. Restart the device where there is no internet connection (phone, laptop)

Sometimes on the smartphone (tablet, laptop) there is some failure (glitch) which can cause a similar problem. Visually, it seems that everything is fine, but there is no Internet without visible to the reasons. In order to exclude such a failure, restart the device.

3. Reference to Wi-Fi network

This step is very important, despite its simplicity and appointment at first sight. You need to forget the Wi-Fi network, and then connect to it again by entering the password (security key). It can solve the problem and restore the Internet connection, for example, if network settings have been changed user or virus.

4. Set the correct date on the Android device

Invalid date Maybe the cause of the Internet problem. At the same time, sites will open, but antiviruses may not work, Google Play. Market, etc. .

5. Disconnect the proxy server

If on your computer or Android device A proxy server is enabled, a situation may also be observed when Wi-Fi is connected, and there is no Internet. Usually such a problem occurs on android.

6. Check the Internet connection settings on the router

Go to WAN or Internet settings on the router. (). Check to be indicated correct connection settings , such as the:

connection type with the provider (view in the contract or on the website of the provider);
login and password, if any required (view in the contract);
the MAC address is correctly specified (check in the contract. If you have reset the router, you may have to go to the Internet provider's office with a passport and contract and ask to prescribe a new MAC address of the router WAN-port).

If your provider uses a PPTP connection, and you have a configuration on your router and now instead of PPTP selected an IPoe (dynamic IP), then naturally the router will not be able to connect to the Internet. In this case, sites will not open on any device.

7. Change the wireless channel

Wireless equipment, which is located next door and works on adjacent channels, can create interference Your router. Try changing the Wi-Fi channel.

And even better, it will first check which channels are more free. This can be done using the Android or Inssider application for Windows.

8. Install WPA2-PSK + AES Encryption for Your Wi-Fi Network

WPA2-PSK encryption algorithm is the most protected. And AES encryption will provide high speed and safety. Most devices, not even new, successfully operate in WPA2-PSK mode with AES algorithm.

Wi-Fi is connected, but the Internet does not work: other causes of the problem

Weak signal

If there is also such a problem from the client device to the router, there can also be such a problem: the device received an IP address, but there is no Internet. Therefore, you first need to check whether the Internet appears when approaching the router (if possible). Then - if the problem is precisely in the distance - somehow try to cut it. If the router is yours, place it in the middle at home.

Some organizations provide free Wai Fi, but in order for you on the Internet, you need to start the browser, enter a password or go through some other authorization procedure. For example, specify the phone number and enter the code from SMS. With such networks, it is better not to contact any information about yourself not to be in order to avoid problems. It is much easier to find another point of access without such nuances.

If you have done everything, but you still have no Internet connection through an active connection via Wi-Fi, there is another option: Configure the static IP address. This method is not a solution in the full sense of the word, but in some cases helps to bypass the problem and access the Internet. To do this, on the smartphone, call the Wi-Fi network connection properties, check the check box. Show additional parameters And select Static IP:

I hope this instruction helped you identify and fix the problem with an Internet connection and now all your devices go to the network, both on wires and wireless network. Questions and additions to the article Write, please, in the comments.

Before you begin to find out why Wi-Fi or Internet does not work, you should know (especially for those who only purchased a Wi-Fi router), which is just enough to connect the provider cable to the router, it still needs to be configured (configure Internet and Wi-Fi network ). All the following methods are valid if you have worked Wi-Fi and the Internet before you, and then suddenly stopped or you cannot connect a new device to Wi-Fi. For convenience, I divided the article into two parts, the first is dedicated to the impossibility to connect to the wireless network, the second part will respond to your questions if you connected to the Wi-Fi network, and there is no Internet.

Cannot connect to Wi-Fi network.

Reloading the router.

The first thing you need to do when problems with connecting to a Wi-Fi network is to restart the router. To do this, simply disconnect the power supply from the router and later connect again. After 1-2 minutes. The device will boot, then try connecting again to the wireless network. To further avoid such situations, I recommend to update the router firmware (perhaps the manufacturer knows about the problem and corrected it in the new firmware).

Enabling Wi-Fi module on a laptop.

Check if Wi-Fi is enabled on a laptop, I will not turn all the ways enable Wi-Fi I described in the article How to enable wi-fi on a laptop .

Changing the wireless network mode.

If you are trying to connect the device (laptop, smartphone) to which more than 5-7 years, it is necessary to consider that it may not support modern mode wi-Fi works -n.. Therefore, you need to switch the router to operation mode, which is supported by the device or enable mixed mode b / g / n. More information about Wi-Fi modes is described. In order to switch the wireless network mode, you need to go to the web interface of the router, go to Wi-Fi settings and select the appropriate mode.

Deleting the SSID refined network name.

One of possible problems It is possible to connect to Wi-Fi - it is a duplication of the Wi-Fi network (SSID). Suppose you came to your acquaintances, they have a Wi-Fi network called "home", you have successfully connected to it. Time passed and already from other acquaintances or at home you met the same network name. Laptop (this also applies to tablets, smartphones) Attempts to connect to the network using a saved earlier password, but it cannot succeed because a new password is used for this name. To solve this problem, you must remove from the list of saved Wi-Fi networks The coinciding network.

To do this, right-click on network icon In the lower right corner of the screen and select "Network and Shared Access Center".

After that you will see a list of saved wireless networks. If you see that the network to which you are trying to connect is in this list, you must delete it from this list. Select the network and click the Delete button. After that, to connect a wireless network, you will need to enter a password.

No Internet via Wi-Fi.

Checking the payment of the Internet.

The simplest thing that may be with a non-working Internet - it's time to pay for it or work from the provider. To find out the situation, call the provider and check if you have a debt for the Internet and are not working on the line.

Static IP address.

One of the problems not to work the Internet may be a prescribed static address not with the network settings that are necessary. In this case, I recommend using automatic receipt network settings. To do this, you need to get into the Network Management Center and Common Access. One way to do this is the right mouse button on network icon In the lower right corner of the screen and select "Network Management Center and Common Access".

Another method is to use hot keys + , Enter the command NCPA.cpl And press ENTER.

It does not matter how much way you used the result will be one - the network connections window will appear on the monitor. Next, you need to click on the wireless connection with two mouse clicks, in the state window that opens, select "Properties" in the Properties window "Internet version 4 (TCP / IPv4)"

Problem with router.

The Internet may not work because of the router failure, the simplest thing that can be done is to restart it. Situations occur when the router resets the Internet settings, then it is necessary to connect to it on a web interface and re-enter the Internet settings, to further experience less problems with the router, I recommend updating its firmware.

Conclusion

In this article I described all methods for solving problems with Wi-Fi and Internet. If the specified methods did not help you, you can describe in detail the problem in the comments and, along with the readers of this site, will try to help you.

Very often we are found such a problem as the lack of access to Wi-Fi. Basically, this problem occurs in the Windows operating system. What is the reason, and what will all be solving the problem? This is now we will try to find out.

So, there are several reasons why the laptop cannot connect to Wi-Fi. Problems, with the settings of the laptop itself, outdated drivers. Let's consider in more detail these reasons and find ways to troubleshoot.

1. The easiest way
The problem lies in the absence of a connected wireless adapter on the laptop itself. In each model of the laptop, the manufacturers are installed on the P keys button on or off the Wi-Fi adapter. Look at the keyboard and find the Wi-Fi symbol, usually it is located on F5, F10 or F12.

Next, we find the Fn function button and simultaneously press the FN and F12 several times (you click on the key where the Wi-Fi icon is drawn), we look at what happens if there are changes. Sometimes it happens that the Fn is not active, because there are no installed drivers, if you press the F12 and FN, the laptop does not respond in any way, then check the FN key, adding or losing the volume.

In addition to the adapter, you need to check whether the network card is connected in the network connection settings. Simultaneously clamp Win + R. In the window that opens, there is a "Open" string, clog it into it: ncpa.cpl and click OK.

A window opens, choose a wireless connection there. If it is written "Disabled", then right-click (PCM) Click on the wireless connection and in the "Enable" click on the window that opens. We are waiting for 2-3 minutes or simply.

Did not help? So we do the following:
Cleash Win + R. The execute window opens, in the "Open" line, drive the device devmgmt.msc and approx.

The device dispatcher window opens. In the list we find the name of your router (there should be the word Wireless or Wi-Fi) Click named Router PKM, and we look if there is a team "Enter". If you see this command in the drop-down window, it means that the network card is not turned on, so you need to click on it and turn on. All, then you check whether Wi-Fi connected.

2. The second reason neither connection is not installed drivers.
Mostly such a problem occurs when Windows is suspended on a laptop.
If the non-professional system installed, it could not, which led to the Wi-Fi disconnection.

To check it, you need to make several simple manipulations:
Through Win + R go to the "Run" window, let the devmgmt.msc command, choose the name of your router from the list. If there are no drivers, then instead of the name of the router, the standard "Ethernet - controller" will be specified.

So, in the list instead of the name of the router, we found "Ethernet - controller". There are two ways to solve the problem:
After installing Windows, outdated drivers for a network card were used. We do the following: We raise your computer, on the day we read its full name and the model number specified on the label.

Next, open the browser, we find the official website and, in the support department, by the number of the model number, pour the required driver package for Wi-Fi. After downloading, you install the driver, and send a laptop to reboot. Sometimes it is not necessary to reinstall drivers, just update enough.

True, for this, too, you need to download the driver from the official site, but you do not need to install it. In the Device Manager, press the PCM by the name of the adapter and then select the "Update Drivers" command. After that restart the laptop and check if Wi-Fi connected.

3. Esch one way to eliminate connection problems.
Press the startup, then the control panel and open the network management center and shared access. We find a wireless network connection, climbing the left mouse button (LKM) by name, window appears: "Status".

Click on "Properties", in the newly opened window appears a list in which we find item: IP version 4 (TCP / IPv4) by clicking on it twice the LCM, a window opens with the DNS settings and the parameters of IP addresses.

Here you definitely put the box next to the box: "Use the following IP address". Indicate the parameters exactly as an example, click OK, and check.

4. WLAN disabled services.
If all of the above methods did not help, it remains the last to check the WLAN autoinavolder service. Of course, the shutdown occurs extremely rarely, but everything sometimes happens, and check does not prevent. So, we press the already familiar combination of Win + R, drive the SERVICES.MSC command and click OK.

In the window that appears, we find: "WLAN autonavructure services" we click on it by PKM, in the drop-down window, run the "Run" command.

Recently, there are many questions on the Internet regarding the problems on setting the access point in Windows 10. Namely, when the device (phone, tablet or other laptop) cannot connect to the access point (distribution) on Wi-Fi, launched on a laptop or computer Wi-Fi router. In this case, users note that there is a continuous receipt of IP address or authentication. And in all cases it is written that it is impossible to connect to this Wi-Fi network. At the same time, many users note that it happened after the next update of the Windows system, and before that everything worked fine.

An interesting point: difficulties with the connection of devices occur regardless of the option to set the distribution: at.

So, if you have Windows 10 and you distribute wireless connection Wi-Fi with a laptop, but the devices connected to it cannot connect to this access point (endless stage of receiving an IP address or complexity with authentication), then this article is what you need. Before writing this manual, I tried several options, including with the launch of the mobile access point. As a result, all my devices connected without problems and never issued errors.

Solutions to problems with the distribution of Wi-Fi from a laptop

You launched an access point on a laptop, which costs Windows 10, but connect to this point the tablet, smartphone or other laptop is not possible. The device gives an error " getting IP Address" or " authentication". Sometimes the system issues " unable to connect to a wireless network". If one of the cases described above takes place, I recommend that you take the following measures:

1 . First of all, I advise you to disable the installed on your laptop antivirus. I'll say right away: it is unlikely that the point is precisely in this, but still recommend it with this simple action. It is enough just to turn off the firewall built into the antivirus program. Also, it will not be superfluous to disable the Windows 10 firewall. Or maybe you have yet installed any programs or applications that can block the connection of devices to the access point?
2 . Check if you have open shared access to the distribution of the network. Make it can be going to " properties"Network providing Internet access for a network configured for distribution.

This is an important point in setting the access point! Here you can face various problems that will be told in the article. If you find that the Internet is not open, then in " properties"This connection will be indicated:" IPv4 connection" or " without access to the network"(" Without Internet access "). So this way:

Attention! Be sure to check the shared access parameters! Make sure that there is an inscription near your connection " public network" or simply " open accessible"(See in Picture).

After selection restart the laptop And again check the sharing settings. Now try to connect to the access point:

If there is an automatic receipt of the address, and there is no connection to the access point, then you need to turn around register the IP and DNS address in manual mode . The IP address must differ from the address of the modem last digit, in our case 192.168.0. (2 ....). The subnet mask will automatically appear, after clicking the mouse over the input field. Value DNS can be used From Google Standard (8.8.8.8 and 8.8.4.4). The screenshot below shows how to do it:

4 . You can try the following: Remove the available connection to the network and create it again. This can only be done in the case of a high-speed PPPoE connection. After creating a connection in "Properties", you need to open sharing networks. In this case, no addresses manually prescribe not required!
5 . Check out the following services:

- Service automatic setting WLAN;
- Common access to Internet connection (ICS);
- Routing.

These services should work by default, their launch is carried out automatically. It rarely happens that for any reason their work turns out to be interrupted. You can check it out by going to " control Panel", Further " system and safety“, “administration"And then in" services"(You can use windows search). If some of the services is disabled, then you need to connect it.

6 . If nothing of the above helps solve the problem with access, then you need to reset the TCP / IP and DNS protocol. It does not always help it, but try certainly. To do this, launch command line from the person of the administrator by pressing the right mouse button on " start"And follow the two commands alternately - inserting into the string and pressing input:

netsh Winsock Reset.

netsh int ip reset c: \\ resetlog.txt

After execution you need reload Laptop, After downloading the system, run the distribution of Wi-Fi again, without forgetting how to open sharing.

7 . There is another original solution that can be applied after all attempts and solution options is a simple reinstalling of the operating system. After reinstalling Windows 10, in almost all cases, problems with access point disappear, including with access through mobile hot spot. Therefore, if you reinstall Windows 10 for you - it is not difficult, it is worth trying.

With such a problem, each user faces everywhere. The laptop simply does not want to connect to Wi-Fi. Sometimes it helps or router, but sometimes these actions remain useless. And the laptop sees and recognizes the network, but it does not want to connect. At the same time, other devices work perfectly with the network. Well, let's try to figure out what is what, and how to resolve a dilemma.

Of all the many reasons for possible, we allocate two large categories. The first includes problems with a computer, and the second - with the router. Therefore, all further ways of influence will be considered, based on this gradation.

We define who is to blame: a laptop or router? If you immediately start setting up one or another system, you can lose a lot of time, and the result is not achieved. Therefore, it is very important to determine which device cannot transmit the signal: your technical machine or a small receiver with an antenna. And you know it very simple. Try connecting another device to Wi Fi. If the signal is accepted, the router works. Similar steps with a computer, simply by connecting it to another wireless network, for example, a neighbor (nothing if you arrive in the door opposite and ask the password). Usually, some of the two components will definitely detect the problem.

Most often a type of message: "Failed to connect to ..." occurs on Windows 7. It is difficult to understand what it is explained, but the fact remains.

Check Drivers

At that moment, when there is no connection to the Internet, such an icon is displayed on the panel:

Let's start with the inspection of the driver's performance. You can see it in the device manager, which is called from the properties of My Computer:

In the proposed list, find the network adapters and see which driver is suitable for your computer. Open its properties. With satisfactory condition, it will be written: the device works fine.

If everything is fine with you, as indicated in the picture, then everything is fine with the drivers. If at least one item does not match, then install them.

Check the connection

For switching on Wi Fi on a laptop, a special small button is responsible. It can be on the side or bottom of the case. She regulates the state of bluetooth. If there is no such, then a combination of keys selected in the screenshot is suitable:

At the final moment of the Windows connection, it loves to issue such a message:

Try to take advantage of the presented and click "Troubleshooting". In history there are cases when it helped. It is difficult to say which problems cause this error. They are hidden much deeper than the ordinary user can get. Therefore, the solution is one thing: first restart the router and then the laptop. This is the most reliable method that helps in 96% of cases.

A fairly common problem today is that WiFi does not connect on a laptop. Usually no data transmission wireless interface is due to incorrect setting software. First point in this the list is coming Random shutdown of the adapter on the keyboard or using a special layer on the housing. Next, you need to check the driver (a program that manages the work of the adapter) and, if necessary, reinstall it. At the last stage, check the network settings. Phaood

the execution of all these items in most cases allows you to eliminate such a problem when WiFi does not connect on a laptop.

Turn on adapter

On the keyboard of most modern mobile PCs, there is an extended function keyboard. It can be used by pressing special keys - "Fn". In this case, the standard set of characters stops working, and you can only enjoy additional. It includes a key with an antenna and extending waves. On most models, it is located in the functional set "F1" ... "F12". If you press the "Fn" immediately and without releasing its key with an antenna and extending waves, then there will be inversion of the current state of the adapter. If it is turned on, it will turn off. To return it to the initial state, you need to press the previously presented key combination. It is important to pay attention to led indicator WiFi. If it is turned off, then it will have to turn on, then the adapter will be in the on state, and will be possible.

Second possibility to turn off wireless network card - Using a toggle. The principle of operation is similar to the previously reduced, with the same combination on the keyboard. When transferring it from one position to another picture will be similar - WiFi does not connect on a laptop and the corresponding indicator does not light. To turn on the adapter, it must be returned to its original state. Depending on the model

mobile PC, can be used both the first and second way of disconnection. In premium models, their combination is possible.

Check Driver

Next you need to check the correctness of the installation of the network adapter driver. Its failure can lead to the fact that the laptop does not connect to WiFi. First you need to find a disc that comes complete with the device. If it is not, then you download the installer from the site of the official manufacturer on the Internet. Then go to the address Start \\ Panel here reveal the item " Network adapters"And look at wireless card. If there are no icons in front of it - it means that it is proceeding for the next stage. We highlight our wireless adapter with the left mouse click and click "Del". This deletes existing drivers. Then we launch the installation of new from the disk or downloaded file. After that, it is recommended to restart the system. If it did not solve the problem, go to the next stage.

Check network settings

At the final stage, check the connection settings. To do this, open

double-click the left button "Current connections" (label with increasing chopsticks On the right side in the list that opens, select the properties of the required Next, you need to check the type of encryption (it should be the same as on the router) and password for access. If the password accidentally changed, It is necessary to check the PC for the presence of viruses. After all three stages are such a problem, when WiFi does not connect on a laptop, in most cases it is solved.

Conclusion

If all the operations set forth in the article are fulfilled, and the result is not achieved, that is, it makes sense to seek help from a qualified specialist. As practice shows, in most cases the proposed manipulations allow you to solve such a problem at which the laptop has stopped connecting to WiFi, and the transfer of a wireless network is restored.

Each user of the smartphone once faced such a problem as the infinite receipt of the IP address - the phone does not connect to WiFi And that's it! In this article I will tell you what to do if the phone does not see WiFi, and instead he constantly writes something like a "authentication error", "Obtaining IP" or "Saved". But I will immediately make a reservation, which is meant that firstly, the smartphone itself is in good condition. And secondly, WiFi network on the router is also configured correctly and everything works on other phones or computers.

I will list the most popular causes of errors at once:

Invalid IP address
Wireless radio channel
Encryption type
China, his mother ..

To directly dispose of a problem when the phone does not see WiFi, which are possible related to the router, try to restart it and make sure that it is turned on by a DHCP server. That is, the router automatically distributes the IP addresses to the devices connected to it.

In addition, you need to make sure that the network SSID is not hidden in the parameters wireless communication on the router - often to protect the connection from "prying eyes", activate this function, due to which the phone does not see wiFi NetworkAlthough it really works.

The reasons why the phone does not connect to WiFi

Now in detail about each item. The first thing I immediately do in case the phone does not connect to WiFi, - I ask a static IP address on it.

For Android and iPhone, this is done almost the same - go to "Settings\u003e WiFi", we see our active connection to the network and click on the arrow (on Android) or on the "I" icon on the iPhone / iPad.

IP for your phone from the range of addresses specified in the router and available for use. If the address of the router 192.168.1.1, then for the phone you can assign 192.168.1.45, for example.
Subnet mask - 255.255.255.0
Router is an IP router. In most models, by default, it has an address or 192.168.1.1, or 192.168.0.1 - try them if it does not work, contact the network administrator.
DNS is also an IP router, or you can use one of the Google public addresses - 8.8.8.8 or 8.8.4.4.

On the android phones It will be necessary to make a page at the bottom to the "IP settings" drop-down menu and change the DHCP to "Custom". Opens additional forms To enter the same parameters.

What if the phone does not see WiFi?

And some more ways to solve the problem, if we are talking about the fact that the phone does not connect to WiFi.

Possible reason Authentication errors can wage in the choice of radio channel for your wireless signal. I talked about it in detail in the article about, so long to explain how to configure it, I will not. And here it is worth noting that modern routers support work up to 16 channels, while the older standard, which the smartphones adheres, had only 11 channels. If your router is configured to the automatic channel selection mode, it can easily switch to channels 12 or 13 (it is 13 channels that are allowed for use on WiFi in Europe), and accordingly, the phone simply does not see it. So if you want a constant and stable connection on all devices, adjust the channel on the router manually from 1 to 11.

If the phone on Android, I want to upset you a bit - the Android kernel does not always work correctly with the WPA2-TKIP encryption type, so if you have such a type of encryption, it may be the cause of Internet problems, and that the phone is written "Connecting Saved" , "Obtaining IP" and other nonsense. This is especially true of cheap Chinese products.

China's theme cannot be circumvented and relative to the routers themselves - often their products have not quite standard operating modes - both by channels and encryption and by other indicators, so the modes of the Chinese router may not be fully understood by the "purebred" android. Exit - change the router to produce a better brand and model class above.
