Problems with wi-fi. Why does the Wi-Fi router not work and what to do? What to do if the Wi-Fi module burned out or is constantly buggy

While working with a PC, laptop, tablet and other devices, users sometimes have the following problem: the router does not distribute Wi-Fi, but the Internet is on the computer. To fix the problem, you will need to perform a few simple manipulations using the recommended methods designed to debug the system's performance and achieve the desired result. Consider the main situations when the router stopped distributing wi fi.

In addition to a computer or laptop, other devices are connected to the Wi-Fi network: a tablet, smartphone, TV, etc. They all work on different systems, but they face a problem that gadgets are not able to connect to a wireless network.

In order to fix this problem, you must first restart the router, and then try to connect again. If a this way does not help, you need to re-create a wireless connection on the network device itself. The wi-fi network name must contain only latin characters. You can also try changing the password, and then reconnecting to the wireless network so that the router is able to distribute the Internet.

The device connects to a wi-fi network, but does not go online

Often the problem when the router cannot distribute “wi-fi” occurs due to device settings failures: for example, time / date desynchronization. It is also possible to reconnect the personal network again. Sometimes it helps to reset the settings to the factory settings on the device connected to the Internet, as well as on the router.

Damaged or incorrectly connected cable

Often the problem when the router stopped distributing wifi, but the Internet is working, is the mechanical damage to the Internet cable or its incorrect connection.

First of all, you need to check if the Internet cable is connected correctly. It should be included in the WAN connector of the router, marked in blue. You should also make sure that one of the LAN ports yellow color(directly for the network card of the computer) the corresponding cable is also connected.

The indicators on the router do not just light up, but, as a rule, signal an Internet connection, as well as the use of one of the ports. When the network cables are properly and securely connected, but the indicators do not light up, you should check the condition of the insulation for mechanical damage: breaks, kinks, etc. In the presence of such problems, the router, of course, is not able to distribute the network.

Problems with the router

There are also options when there is Internet on the network equipment, but the router does not distribute the Internet via wifi. The causes of the problem are different, often associated with the incorrect operation of the router itself. Some users believe that if the router stops distributing the Internet, the device stops being functional. However, it is worth debugging the parameters of the adapter, as well as the computer itself.

Signs that determine the failure of the router:

The laptop or computer does not detect the Wi-Fi network.
The connection is unstable. There are constant disconnections and reconnections.
The modem gives out extremely slow speed.
The device is connected to Wi-Fi and the router is working, but there is no access to the global network.

Thus, before replacing your router, which is unable to distribute the network, you should check and reconfigure it. The solution to the problem, when for some reason the router does not distribute “wi-fi”, but the Internet is on the computer, is carried out not only by programs, but also by hardware verification.

If the wireless connection is not established, then the problem is in the wifi settings on the router. But if the rest of the devices are stable, the problem lies in the equipment making useless attempts to connect via wifi.

Each router has a special button that is responsible for turning the device on and off, with the help of which the router reboots. In order to check its physical health, you should press the button and make sure that the indicator with the Wi-Fi icon lights up on the case. If this happens, the router is technically sound and, in all likelihood, is able to distribute the network.

There are a lot of reasons for software problems when the router does not distribute the Internet via wifi, ranging from the features and settings of the network card to blocking the Wi-Fi connection by antivirus. Among the most common problems are errors in the configuration settings of the operating system itself. This is especially true in cases where the computer was previously connected to another provider. To check or reconfigure on Windows 7, you will need to take the following steps:

Open "Network and Sharing Center".
Click on the "Change adapter settings" button.
Click on "Wireless Properties".
Next, a small window will open where you should find the line "TCP / IPv4 protocol" and go to its properties.
The above manipulations will open the network card settings. Here, opposite the corresponding lines, you should enter your own IP address, gateway and DNS server addresses, if they are known. Sometimes it is recommended to set markers on the automatic address acquisition functions.
After entering and confirming all changes, restart the computer. Internet setup is complete.

If the above manipulations did not have the expected effect, you need to dive directly into the interface of the router itself. This is necessary in order to change the address in the wireless adapter settings.

To do this, you must perform the following steps:

This manipulation is performed in order to exclude the simultaneous operation of several routers, for example, with neighbors when the single channel mode is in effect. This channel related issue is quite common. For greater efficiency, it is recommended to try and compare the work on each of the channels.

In addition, you need to check whether the Wi-Fi distribution function is enabled on a specific router in its settings.

If the wireless network settings section of the router does not contain a checkmark next to the Enable Wireless Router Radio item, it must be checked in order for the router to be able to distribute the network. In some situations, it will be reasonable to reset the settings to the factory settings, and then completely reconfigure everything. To do this, press and hold the button on the router for at least ten seconds.

Connected device problems

Computers and laptops sometimes have erroneous network settings using incorrect addresses or parameters, which should be double-checked before connecting gadgets to the Internet. In addition, some antivirus and other security programs can block the connection and access to the Internet. In some situations, it is recommended to reinstall the wireless device driver.
Devices with various systems have different parameters, so often the problem when the router stopped distributing “wi-fi” is not only in the connection settings.

Conclusion

This article discusses the situation when a working router for some reason stopped distributing wi fi (device network), recommendations are given for resolving such a problem when the router works, but does not distribute the Internet.

Hello, friends. If you are having problems with Wi-Fi operation router, or setting up Wi-Fi and you have already looked at the article, which by the way is the most popular on this site, then you probably noticed that the article has collected a lot of comments, or rather questions about various problems about setting up and operating a Wi-Fi network.

Of course, the questions there are very different, we have already dealt with some, and I wrote separate articles about their solution, for example. And I can't give a concrete answer to some questions yet. But after analyzing the comments a little, I noticed that there are a lot of questions of this type: the laptop and other devices stopped connecting to the Internet via Wi-Fi, or the Internet via Wi-Fi often cuts out, you have to restart the router.

In fact, there can be a lot of reasons that lead to such problems and almost always and they are different for everyone. For example, I'm on my router TP Link TL-WR841N I have never noticed a Wi-Fi network break, and judging by the comments, this happens very often for others.

Even more interesting case, which I also met in the comments, is when the Internet is working, and at one fine moment the Wi-Fi network stops working. Devices either do not connect at all, or connect, but work with the network status without access to the Internet, or access is limited. Phones and tablets connect to Wi-Fi, but sites do not open.

What to do if the Internet through Wi-Fi stops working?

Problems with Wi-Fi Internet:

WiFi internet stopped working
Wi-Fi drops frequently
Wi-Fi internet is very slow
Devices connect to the router once.
The device connects to Wi-Fi, but the sites do not work (the sites do not open).

If you have one of the above problems, or a similar problem, then I have one tip that may help solve it. Friends, I do not guarantee anything, but it's worth a try, in many cases it helps.

Every Wi-Fi network operates on a dedicated channel. When configuring the router, the default is "Auto", and everyone advises, including myself, to install the Channel (Channel:) on the "Auto". This means that the router itself will look for a more suitable channel and use it. The thing is that there may be interference from a nearby Wi-Fi router and then a variety of problems with Wi-Fi may appear. Refusal to connect to the network, network without Internet access, and frequent breaks.

You need to try changing the value of the Channel (Channel:) parameter to any number from the list, or if you have a specific value set, then try changing it to “Auto”.

How to change the channel (Channel) on a Wi-Fi router?

Everything is simple here, so you should not have any problems. You need to go into the settings of the router, well, I hope you already know how to do this, I have already written about this many times. Apparently it will be necessary again, very briefly :). Connect the router to the computer network cable(at the time of setup) and enter the address of the router 192.168.1.1 in the address bar of the browser. Enter your username and password and click "Send", enter, or whatever you have, it doesn't matter.

I will show an example on, but even if you have a different model, or even a company, then I think that the process of changing WiFi channel does not differ much.

Go to the tab “Wireless” and on the left we find the item “Channel”.

Near it there is a drop-down menu in which you can select a channel. I advise you to try several channels, at your discretion, after each channel change, do not forget save changes by clicking the “Save” button and reboot router. If you already have a certain number set next to “Channel”, then try setting the value to “Auto”.

There is a program that you can see which channel is already occupied by neighboring Wi-Fi, and which is not, it's called inSSlDer. But I will not describe it here, because it is more suitable for wifi settings networks for more stable operation. And this is the topic of another article. Although if your devices find a lot of neighborhood networks, you can try this program.

Try the method that I described above, it definitely won't get worse. And judging by the reviews on this site, the steps to change the Wi-Fi channel on the router really help to solve the problem with unstable Wi-Fi, or in general, solve the problem when not a single device wants to connect to the Internet via Wi-Fi, or connects, but the network does not have internet access. Good luck.

The router does not respond to the connection to the mains

I'm sorry, but your router is most likely completely "dead". On every router (well, almost everyone) There are performance indicators.

And if, when the device is connected to the outlet, these indenters do not get hot, then this is very bad.

What can be done?

Well, first check if there is a power off button on the router. Here is such a button on the TP-LINK TL-MR3220:

If the button is on, then you need to check the power supply, maybe it's in it. Usually, power supplies burn out more often than the routers themselves. Perhaps the neighbors have the same router, run and ask for a couple of minutes.

If the device still does not work, then return it under warranty. And if there is no guarantee, then it is better to throw it away and buy a new one than to give it for a paid repair. Although, you can take it to the workshop, it may not be very expensive to repair it.

Why is this happening?

For many reasons. A manufacturing defect is possible, but most likely the router burned out due to unstable mains voltage, a thunderstorm, or moisture. If possible, connect the router through a voltage stabilizer. Well, or just turn it off when you see that there will be a thunderstorm now.

This was the most severe case, now let's look at lighter breakdowns.

The router stopped working, does not distribute the Internet

If suddenly there was a problem with Wi-Fi, for example, all devices stopped connecting to the router, there is a connection, but the Internet does not work, etc. then do not rush to throw your router out the window :).

First you need to find out that the problem is really in the router, and not in the device you are trying to connect. How? Just try to connect another device (laptop, tablet, phone). If only one device does not connect, then the problem is most likely in it. Well, you understand what I mean.

The problem is in the router, what needs to be checked and how to solve the problem?

Do not rush to immediately go into the router settings and immediately change something there. And then set it up in such a way that it will definitely not work. Believe me, I'm not just writing this :).
Reboot your router. Restart your computer (phone, tablet).
Call your ISP and ask if there is a problem on their end. Explain your problem to them. Perhaps the Internet is not working due to problems in the provider's equipment.
Check if you have paid for the Internet and whether it is active (You can also ask your ISP for this).
Check all connections. Internet cable that connects to the router. It is advisable to check this cable outside the apartment (house). Maybe you just cut the cable. On purpose or by accident, it happens.
Look at the case of the router, maybe there are some interesting buttons that someone accidentally switched. For example, there may be a button to turn off the Wi-Fi module. If you press it, the devices will not see your wireless network.
Go to the router settings and see if the settings have been lost. This may be the Internet will not work. Especially, check the WAN tab, where the settings are from the provider. If it crashes, set it up again. Here is an example article for you.
Try changing the channel in your router settings. Here is a detailed article. How might this affect obscure Wi-Fi issues? Perhaps your neighbors have installed a router and not one, I will introduce neighbors from above, below, on the sides. And just all the channels (or the one you are on) busy. That's when the problems begin, which are even difficult to explain.

Have you tried everything and nothing helps?

Then, I advise you to give the router for repair, again under warranty. And if there is no guarantee, then for a paid repair, or buy a new one. Before that, you can ask a friend who understands this matter (if there is one) so that he looks at the router, settings and connection.

Real case. My TP-LINK TL-MR3220 router worked fine for several months. Then, suddenly, it stopped detecting the connection of a 3G modem. I connected different modems, the modem is powered, but it does not appear in the control panel. I tried everything, even the special firmware that TP-LINK support sent me - did not help. You can read more in the article.

This is what I mean if it happens technical problem in the router (there's something going on there), this does not mean that it simply will not turn on. It can work, but it doesn't work the way it's supposed to. And it can be very long and painful to set up, flash, check, etc.

Don't suffer. You paid money for this device. Call the support of the manufacturer of the router, explain the problem to them. I'm sure no one will give you best advice than they are.

If support cannot help you over the phone, they will advise you to apply for a warranty (if any). And there it is up to you to decide whether to go for repairs, or buy a new device.

Good luck!

Why Wi-Fi does not work on the phone: possible reasons

All problems can be divided into two groups according to their origin:

incorrect ones that interfere with the transfer of data from the access point;
wrong settings for Wi-Fi router, due to which the mobile device cannot connect to the wireless network.

Let's consider all cases in more detail.

The Internet does not work on the phone via Wi-Fi due to a malfunction of the device itself in the following situations:

Failure of the wireless network adapter in the smartphone;
Wrong settings in the device menu.

In the first situation, you need to take your smartphone to a repair shop so that the experts restore the adapter to working order (often it comes out of its connector when it is shaken or dropped) or replaced with a new one. If Wi-Fi stopped working after repair, then all the blame lies entirely with the service center.

In the second situation, you can try to set up a Wi-Fi connection yourself. To do this, go to the settings menu.
Depending on the manufacturer and operating system, you should select the "Wireless Network" section.
Next, click turn on Wi-Fi
and select your home router from the list of found access points.

If the smartphone does not see the Wi-Fi router at home, but connects to other modems, then the problem is in your router.
If this did not help and the Internet still does not work on the phone via Wi-Fi, then you can try to make a Hard reset or just reboot mobile device.

In order to make a Hard reset, dial the command *2767*3855#. Attention! AT this case all data will be deleted from internal memory phone (contacts, photos, videos, programs, settings). Therefore, do not forget to backup or copy them to your computer.

We figured out why the smartphone does not see the Wi-Fi network. But what if the phone connects to the router, but the Internet still does not go?

Let's try to solve this problem.

Why is Wi-Fi not working on my phone after connecting?

If your device is properly connected to the wireless network, then it does not want to access the Internet through a mobile browser, then you need to reconfigure the router. Carefully review the list of blocked devices in the modem settings - perhaps your mobile device got there.

Also check out our detailed article on this topic:

We have prepared detailed instructions for those users who do not have Wi-Fi on the router. We will also consider questions such as why the Internet does not work through a router, and what to do if the router does not work. Below is a list of solutions to the most common home router problems.

Make sure Wi-Fi is on

If you are using a laptop, make sure Wi-Fi is turned on. Most laptops have function key to enable / disable Wi-Fi on the computer. For example, on an Asus laptop, this is the F2 key.

Make sure the wireless connection is enabled

If you have turned on Wi-Fi on your computer, but the Internet is still not working, then you should check the wireless connection. To do this, click "Start" and start typing the following text on the keyboard "View Network Connections". Then you will see the corresponding section, go to it.

In the window " Network connections” will display the wireless connection on the laptop. Right-click on the wireless connection and select "Enable". If you see "Disable", then the network connection is already enabled.

Make sure the SSID and security key are correct

If your computer or laptop shows multiple available wireless networks, make sure you are connecting to the correct SSID (name of your router) and that you have entered the correct security key (password). If you connect to a neighbor's router and enter the wrong security key, of course, the Internet will not work.

Make sure the Internet is working

If you are connecting to the right router, but wi-fi still does not work, make sure the Internet works at all. It is possible that the problem is not with your computer, but that the Internet simply does not work.

Try connecting to the router through another device, such as a smartphone, tablet, or laptop. If the Wi-Fi works on another device, then it is safe to assume that the problem is with the computer.

Restart your router

If the router is not working and is not sharing Wi-Fi, the first thing you should do is to reboot it. Quite often, popular routers have errors that prevent one or more devices from connecting to the network.

You need to disconnect the power from your router, wait 10-15 seconds, then reconnect the power. Wait a few minutes for the router to reconnect to the Internet, then check the Wi-Fi on your device. If the problem is still present, try restarting your computer.

Turn off firewalls

If you have several firewalls installed on your computer, this may be the reason why the Internet does not work through the router.

To make sure that the firewall is not causing problems with your Wi-Fi connection, we suggest that you temporarily disable the firewall. If the Wi-Fi works, then you should permanently disable the firewall or even remove it.

Restore Windows to an earlier copy

If at one point your Wi-Fi stopped working on your router, try restoring Windows to an earlier copy. In some cases, bad software or incorrect settings can cause problems with your Wi-Fi adapter or problems accessing the Internet.

Reinstall your wireless device and drivers

Corrupted drivers or other problems with the wireless device may be the reason why the Wi-Fi router does not work. Make sure you don't have driver issues by following the steps below.

Open the dispatcher Windows devices(right click on Start and select Device Manager).
In Device Manager, expand the Network adapters section to view all network devices.
Highlight your Wi-Fi or wireless network adapter and press the Delete key on your keyboard to remove the device.
Once the device is removed, close all windows and restart your computer.

After the computer is booted, the Windows operating system will automatically install the necessary drivers for the network card.

Move the router to another location

It is possible that the Internet through the router does not work for you, because the computer does not receive sufficient signal strength. Make sure the router is located close to the computer and its antennas are pointed at your device.

If the location of the router is the problem, then you should consider purchasing a Wi-Fi extender (also called an extender or extender). Install it between the router and the problem area to increase the Wi-Fi coverage area and eliminate interference.

Update your router firmware

If you have tried all the methods above and nothing helps, then you can try updating your router's firmware to fix the problem. Search the Internet for instructions on how to reflash your particular router model.

Operating system malfunction

Still not working Wi-Fi on the router? Another reason may be corrupted files in the operating system. We suggest a complete reinstall operating system Windows.

Faulty hardware

If you have tried all of the above suggestions, and Wi-Fi still does not work on the router, the router itself is probably broken, or the Wi-Fi adapter on the computer. In any case, you should check the wireless connection on a computer with another router, or connect a smartphone or tablet to your router to find out for sure what the problem is.

If the problem is in the computer (laptop), then you need to take it to a service center for replacement motherboard or network card.

If the router is defective, you will probably have to buy a new one, because routers are almost unrepairable.

That's all! We examined the most common reasons why the router does not work, as well as what to do to make Wi-Fi and wireless Internet appear.
