Problems with WiFi router - diagnosis and solution. Typical problems with Wi-Fi routers Wan state is broken

You have configured your wireless router, but for some reason it does not want to work. Let's look at the most common problems in setting up a Wi-Fi network with routers and ways to solve them.

Here are the most typical problems that users encounter when, it would seem, they have configured everything exactly and according to the instructions:

The router status indicates that the WAN connection is down;
The Internet is available on the computer, but is not available on a laptop, tablet, or other devices;
I can’t access the address 192.168.0.1 or 192.168.1.1;
A laptop, tablet, smartphone does not see Wi-Fi, but sees neighbors’ access points;
Constant disconnections;
The provider's local city resources, torrent, DC++ hub and others are not available.

The WAN is broken or the Internet is only available on the computer.

The main reason why this problem occurs with a WiFi router is the connected WAN connection on the computer. The point of setting up and operating a wireless router is that it will establish a connection to the Internet on its own, and then “distribute” access to other devices. Thus, if the router is already configured, but the Beeline, Rostelecom, etc. connection available on the computer is in the “connected” state, then the Internet will only work on the computer, and the router will take virtually no part in this. In addition, the router will not be able to connect the WAN, since it is already connected on your computer, and most providers only allow one connection from one user at a time. I don’t know how clearly I was able to explain the logic, but even if it’s not clear, just take it for granted: for everything to work, a separate provider connection on your computer must be disabled. Only a local network connection should be connected, or, in the case of a laptop, etc., a wireless network connection.

It is impossible to access the address 192.168.0.1 to configure the router

If you encounter the fact that when you type the address to access the settings of your router, the corresponding page does not open, do the following.

1) Make sure that in the local network connection settings (your direct connection to the router) it is set to: obtain an IP address automatically, obtain DNS addresses automatically.

UPD: Check whether you enter this address exactly into the address bar - some users, when trying to configure the router, enter it into the search bar, resulting in something like “The page cannot be displayed.”

2) If the previous point did not help, use the run command (Win+R keys, in Windows 8 you can simply start typing the word “Run” on the start screen), enter cmd, press Enter. And in command line mode, enter ipconfig. Pay attention to the “Default Gateway” value of the connection used for configuration - it is at this address that you should go to the router administration page. If this address differs from the standard one, then perhaps the router was previously configured to work on a specific network with certain requirements. You can reset it to factory settings. If there is no address at all at this point, then, again, try resetting the router. If that doesn’t work, you can also try disconnecting the provider’s cable from the router, leaving only the cable that connects it to the PC - this may solve the problem: make the necessary settings without this cable, and after everything is configured, reconnect the provider’s cable. Pay attention to the firmware version and, if relevant, update it. If this does not help, make sure that the “correct” drivers are installed for the computer’s network card. Ideally, download them from the manufacturer's website.

Settings are not saved

If for some reason the settings are not saved after entering them and clicking “save”, and also if you cannot restore the settings previously saved in a separate file, try performing the operation in a different browser. In general, in case of any strange behavior of the router admin panel, you should try this option.

Laptop (tablet, other device) does not see WiFi

In this case, a variety of options are possible and they are all approximately equally common. Let's go in order.

If your laptop does not see the access point, then first of all, check whether the wireless module is turned on. To do this, look at the Network and Sharing Center - Adapter Settings in Windows 7 and Windows 8, or Network Connections on Windows XP. Make sure your wireless connection is turned on. If disabled (displayed in gray), then enable. The problem may have already been resolved. If it doesn’t turn on, see if your laptop has a hardware switch for Wi-Fi.

If the wireless connection is turned on, but is constantly in the “No connection” status, make sure that the required drivers are installed on your Wi-Fi adapter. This is especially true for laptops. Laptop computers often use specific hardware, and using drivers (not just for network equipment) recommended by the manufacturer can avoid many problems.

If the previous option did not help you, try logging into the “admin panel” of the router and slightly changing the wireless network settings. First: change b/g/n to b/g. Did it work? This means that the wireless module of your device does not support the 802.11n standard. It's okay, in most cases, this will not affect the speed of network access. If it doesn’t work, try manually specifying the wireless network channel there (usually “automatic”).

And one more unlikely, but possible option, which I had to deal with three times, and twice for the iPad tablet. The device also refused to see the access point, and this was solved by setting the United States region in the router instead of Russia.

Constant disconnections

If the connection constantly breaks during operation, make sure that you have the latest firmware installed; if this is not the case, update it. Read the forums: perhaps other clients of your provider with the same router that you have already encountered such a problem and have solutions to this matter.

Problem setting up the router. Can't login to admin panel

First of all, we will look at the case when we are unable to log into the control panel of the router. This is the same “admin panel”, page with settings, personal account, web interface, etc. If we cannot access the settings of our device, then accordingly we cannot configure it, or change some parameters.

As it usually happens. From the device that is connected to our router, we go to the IP address 192.168.0.1, 192.168.1.1, or by hostname (address of letters). And an error appears in the browser that the page is unavailable.

Important point! In order to enter the router settings, you do not need an Internet connection. The connection status on your computer may show a yellow exclamation mark.

Main reasons and solutions:

The device you are trying to access settings from is not connected to the router. The connection can be either via cable or Wi-Fi. Check the connection.
Some IP settings are registered on the computer. You need to set automatic receipt of addresses. For more information about this, see the article linked below.
Make sure you are going to the correct address. Usually the address is listed on the router itself.
If possible, try logging into the web interface from another device.

No internet connection. Problems with WAN. Internet only works on PC

The most important thing in setting up and operating a router is the correct configuration of the connection to the Internet provider. It is very important. Now I will try to explain everything in simple language. Every internet service provider uses some type of internet connection. It could be:

Dynamic IP– a popular type of connection for which you don’t need to configure anything. The computer or router itself receives the address from the provider and everything works.
Static IP- rarely occurs. To configure it, you need to register static IP addresses issued by your provider.
PPPoE, L2TP, PPTP– popular connection types, to configure which you need to specify a username, password and/or server address.

After installing the router, we go to its control panel. In the section where Internet connection settings are set. It is usually called "Internet", "WAN", "Internet". In this section, we select the type of connection that our provider uses and set the necessary parameters. Which are issued by the provider when connecting to the Internet. On TP-Link routers it looks something like this:

Of course, on devices from different manufacturers, these settings will differ.

If you had the Internet connected to your computer, and a high-speed connection to the provider was configured on the computer, then after installing the router you do not need to start it. We simply configure this connection on the router, and it will launch it itself. And we simply connect the computer with a network cable. Without starting any connections.

It is precisely because the router is not configured correctly that the Internet may not work on the devices connected to it. There will be an error "No Internet access". I wrote a separate instruction about this: .

Sometimes it happens that the Internet only works on one computer, or only when the computer is turned on. All this is also due to incorrect settings. Or when you run a high-speed connection on a PC. I also wrote about this: .

I think we've sorted this out.

Problems with the Wi-Fi network on the router

This malfunction should be divided into two categories to avoid confusion. Because the solutions there will be different.

When the router does not broadcast the Wi-Fi network at all. Your laptops, tablets, smartphones do not see the network.
When there is a Wi-Fi network, devices will connect to it, but the Internet does not work. No internet access.

People often write to me saying that the router has stopped distributing Wi-Fi. And try to understand, the wireless network has completely disappeared, or it is there, but the devices do not access the Internet. Let's look at these two situations.

When the wireless network disappears completely

Reboot the router. If it doesn’t help, then check the button that is responsible for turning the wireless network off and on. It is available on a large number of models. It looks something like this:

It may have been pressed accidentally.

Also, please note that for some reason the router may have reset the settings, and now the Wi-Fi network has a standard name. It is indicated on a sticker on the bottom of the device.

When there is Wi-Fi, but no Internet

We also first reboot the router. Let's see if the Internet has disappeared on all devices, including cable. It would be nice to connect the Internet directly to the computer and check if it works. Maybe the provider has some kind of problem.

I wrote in more detail about these problems in the article:. Both problems are addressed there. Everything is detailed and with screenshots.

Slow Wi-Fi speed and unstable wireless connection

As for the speed of the Internet over a wireless network and the stability of this network, everything is very ambiguous and blurry. When you install a router, you need to be prepared for the fact that the speed will be lower than via cable. And the speed of the Wi-Fi network itself depends on a large number of different factors: the router, the speed provided by the provider, the type of connection, interference, the number of neighboring networks, the signal level, the device you are connecting, etc. I have already talked about.

Some tips:

Check the cable speed to see how much lower it is over the air.
Try changing the channel of your Wi-Fi network. Read how to do this.
Test speed on different devices. Perhaps the problem is in the client itself (device you connect). It may have an outdated wireless adapter installed. You can try updating the wireless adapter driver (if it's a computer or laptop).
You can experiment with the network operating mode settings and channel width. Read more about this at the link below.
Update your router firmware. If it turns out that the problem is there.
Transition to 5 GHz frequency. If the poor speed is due to interference or a large number of neighboring wireless networks, then it may make sense to think about choosing Wi-Fi support at a frequency of 5 GHz. Might be useful: .

As for the unstable operation of the wireless network, you can apply the tips that I wrote about above. Or just follow the link: .

The router has to be rebooted frequently

This problem looks like this: everything works, the devices are connected, the Internet is available, and at one moment access to the Internet disappears. On computers, a yellow exclamation mark appears next to the connection icon. This happens on all devices simultaneously. Reboot the router (turn off and on power), and everything works again, until the next such break.

The Internet may disappear several times per hour, day, week. But this is a little annoying, you constantly need to reboot the router. If you do not reboot, access to the Internet will not appear. Of course, I cannot say with complete confidence, but most often this problem arises with budget, weak routers, or already old devices. And most likely the break occurs precisely at the moment of increased load on the router. Video, online game, torrent, etc.

Why does this happen: due to some hardware problems on the board of the router itself, or in the power supply (as often happens), it simply cannot withstand the load and freezes. It’s difficult for me to explain this from a technical point of view, but we don’t need it.

What you can try to do in this situation:

Update the firmware. This is the first thing to do.
Disable programs on your devices that may overload the network. For example, torrent clients. If you don't download anything.
You can reset the router settings and configure it again. Maybe some parameters were set there earlier that you have already forgotten about, and which affect the operation of the network device.
See if your router is getting hot. Place it in a place where it will cool well.
If you have a lot of devices that create a heavy load on the network, and all this on different devices at the same time, and at the same time you have a budget router for $15, then most likely you will have to change it to a more powerful one. Especially if you observe breaks at times of increased load.

Settings are not saved, the web interface is displayed crookedly

I often hear about problems when the router does not want to save the specified parameters. After clicking the save button, either nothing happens or some error appears. Also, there are often cases when the settings page is displayed somehow crookedly. There are some sections missing, inactive links and buttons, everything has moved out, etc.

Whenever you encounter such cases, the first thing to do is try setting up from a different browser. Or better yet, from another device.

If the router still does not save the settings, then try to reflash it. Or return it to the store (if it's new). Since it is possible that this is a hardware failure. And the settings may disappear after each power outage. And this is not normal, it shouldn’t be like this.

The indicators on the router are lighting/blinking incorrectly

Indicators, which are found on almost every router, signal possible malfunctions or breakdowns. For example: if the Wi-Fi indicator does not blink, then the wireless network is not working for some reason.

What a specific indicator is responsible for and its operating modes should be described in the instructions that were included in the kit. Depending on the manufacturer and model, this information may vary.

If, for example, all the indicators are on and do not go out, or only the power light is on, sometimes with an indicator in the form of a gear, then this very often indicates a hardware failure of the router.

And if this happened during a firmware update, then perhaps there is a chance to restore the router. How I did it with TP-Link in .

But as practice shows, the strange behavior of the indicators on the router means a breakdown in the hardware. The first thing you need to do is reset the settings. But this doesn't often help. And in most cases you have to buy a new router. Since repairing this equipment is not always justified. So it might be useful to you.

Afterword

Of course, it is impossible to collect all the problems and their solutions within the framework of one article. In addition, there are a lot of different manufacturers and different models of routers on the market, everyone has a different Internet connection and different devices. And a lot depends on this. Those same errors, symptoms and problems can vary greatly. Well, you need to understand that this is technology, and any technology breaks. Sometimes there are such cases and breakdowns that it is simply impossible to give them some kind of logical explanation.

When some kind of malfunction appears, many are simply sure that it is something in the settings. You just need to press one button and everything will work. Perhaps I will upset you, but this is not so. More precisely, this is not always the case. Routers often break down, something burns out in them, power supplies fail, LAN and WAN ports burn out. It is clear that it is almost impossible to fix this with your own hands and at home.

To understand what the problem is and how to solve it, try to analyze why the malfunction occurred, what could be the problem, how other devices behave, etc.

Be sure to write in the comments. Ask questions, share tips and your observations on this topic. Best wishes!

In this article we will talk about troubleshooting common problems with Wi-Fi routers.

After setting up the router, problems may occur. Among all the problems, the most common ones are:

Frequent loss of connection and poor Wi-Fi speed

If the connection is constantly disconnected and the download speed via Wi-Fi is very low, it is recommended to change the wireless network channel. An important point: this will not help eliminate router freezes.

Also check the firmware version of your equipment and update if necessary. Look for reviews from other users about your provider; perhaps solutions to the problem have already been found.

WAN breaks

In most cases, the reason for this is that the desktop computer is connected via WAN. Only one WAN connection is available to the user, and if it is used by a computer, the router will not be able to connect the WAN and “distribute” the network to other devices. To fix the problem, you will need to remove the separate connection to the provider on your desktop computer by setting up a local network connection.

I can't access the router settings page

If your browser does not open page 192.168.0.1 or 192.168.1.1 with router settings,

1. Enter the address directly into the address bar, rather than into the search box.

2. Check connection settings. Having selected a local network connection, check the boxes: obtain an IP address automatically and obtain DNS automatically.

3. Use the “Run” command (Win + R keys). Type cmd and press Enter. Enter the ipconfig request. Among the displayed data, find “Default Gateway”. You need this address to configure the router. If there is no address in this item, reset the settings on the router. You can also try disconnecting the ISP Internet cable from the router, leaving only the one connecting it to the computer. Configure the router again, and then connect the cord to the router.

If there is no address in this item, reset the settings on the router. You can also try disconnecting the ISP Internet cable from the router, leaving only the one connecting it to the computer. Configure the router again, and then connect the cord to the router.

Router settings are not saved

If after entering the settings, they are not saved, try repeating the same thing in another browser. This is also recommended if you have problems setting up your router.

Laptop, tablet, smartphone does not see the Wi-Fi network

If wireless networks are not displayed on your device, first check whether the wireless module is turned on.

On Windows laptops, this can be done in the Adapter Settings section of Network and Sharing Center. Check if your wireless connection is turned on. The problem may be exactly this. Your laptop may have an external Wi-Fi switch. It must be enabled.

If the problem is not resolved, check the installed drivers of your Wi-Fi adapter. Perhaps they need to be updated. Updates are located on the laptop manufacturer's website, but look for drivers specifically for your model.

If the above methods did not help, try changing the router settings. Put b/g/ instead of b/g/n. Did it help? This means your device is not compatible with the 802.11n standard. If there is still no connection, specify the Wi-Fi network channel manually.

On tablets (often iPads), the same problem can be solved by changing the Russia region to United States in the router settings.

Torrent or other resources do not work

Some Internet providers restrict access to torrents or game servers. You will need special settings for static routes in your router. Most likely, you will find all the necessary information on the forums of your provider.
