Why does the computer lose wifi. We solve the problem with disabling WI-FI on a laptop

Very often there are cases when Wi-Fi on a laptop turns off by itself. Now we will figure out why the Internet over Wi-Fi disappears, and how to solve this problem. If you have come to this page, then you most likely already have such a problem. We connect our laptop to Wi-Fi, the Internet works, but sometimes it disappears by itself. There is one important point here: Wi-Fi does not turn off at all, but simply goes into the status "Without access to the Internet", or "Limited" (and a yellow exclamation mark appears). Well, the internet doesn't work. Although, there are times when the computer is completely disconnected from the wireless network. This problem is not uncommon on Windows 7, Windows 8, and Windows 10. So it doesn't matter what operating system is installed on your laptop.

As a rule, the connection to Wi-Fi is lost periodically, or after waking up from sleep mode. There are times when the internet stops working for a few seconds and then reappears. In any case, this creates a lot of inconvenience. You have to wait, restart your laptop, file downloads, watching movies, etc. are interrupted.

Important point! We will look at solutions when the Internet is disconnected on only one laptop. That is, other devices that are connected to your router continue to work normally. If the Internet disappears on all devices, both via Wi-Fi and cable, then this is already a problem in the Wi-Fi router, or some kind of problem with the Internet provider.

If you have a problem observed only on one computer, then now we will try to solve it.

Why does the Wi-Fi connection disappear on a laptop?

The main reasons for disconnecting the connection with the router:

  • Interference on the channel on which your Wi-Fi network operates. Or, a weak wireless network signal.
  • Disabling the Wi-F adapter to save power (Wi-Fi disappears when waking up from sleep mode)
  • Unstable operation of the Wi-Fi adapter driver.
  • Problems with the router

I will show on the example of Windows 7. If you have Windows 8.1, or Windows 10 and the Internet also disappears every 5 minutes (may be more or less) then these tips are for you. As for Windows 10, there are now a lot of problems with drivers. Therefore, when the connection is broken in the "top ten", I would first of all advise experimenting with the wireless adapter drivers and try to follow the recommendations from this article:.

Disconnecting Wi-Fi due to interference and weak signal

Our home wireless network operates on a specific channel. As a rule, there are many other, neighboring networks in the radius that can interfere. Interference can also be from other household appliances. And in conjunction with a not very stable wireless network signal, this can lead to disconnection of the Internet on a laptop. A yellow exclamation mark "no internet access" may appear, and work again after a while.

Also, disconnection can occur due to a bad signal when you move far from the router, and on the laptop, where the signal strength is displayed, there are one or two divisions left. In such cases, the connection may disappear altogether. If the Internet is constantly cut off in those rooms where the Wi-Fi network signal is weak, then we need to strengthen the signal of our network so that the connection is more stable. I wrote about this in an article:.

As for problems with interference, here you need to experiment with the channel on which your network operates. You can try using a special program to find the freest channel, and set it in the router settings. Or, just set some kind of static channel in the router settings. How to do this, I described in detail in the instructions: If you already have a static channel, then set it to Auto.

This is how the channel change on the Tp-Link router looks like:

Pay attention to the conditions under which disconnection from the Internet occurs. This can be for example moving around the house, or only in certain places (rooms). Then it will be easier to find the cause and eliminate it.

What to do if the Internet disappears after waking up from sleep mode

This is because Windows disables the Wi-Fi adapter during sleep mode to save power. And when you exit sleep mode, the adapter can no longer work normally, and you need to restart the laptop. Also, problems are often observed when the laptop is running on battery power. We need to disable the wireless adapter, and set the maximum performance when running on battery and mains.

Let's set up the power plan first. Press keyboard shortcut Win+R. Copy command control powercfg.cpl in the "Open" line, and click on the button Ok.

A window with power plans will appear. I advise you to choose Balanced. Next, click on the link next to this plan Setting up a power plan.

Next we open Change advanced power settings. We are looking for a section Wireless network adapter settings, open it and install Maximum performance during mains and battery operation. Click Apply and Ok.

We prohibit turning off the Wi-F adapter to save energy

Turning off the adapter will not save us a lot of electricity, but problems in its operation may appear. Therefore, you need to prevent Windows from turning off the adapter.

Click Win+R, copy the command mmc devmgmt.msc and press Ok.

The device manager will open. Find and open a tab Network adapters. Then, right-click on the Wi-Fi adapter (its name should contain the words "Wi-Fi", "Wireless") and select Properties.

Go to the tab Power Management, and uncheck the box Allow this device to turn off to save power. Click Ok.

We reboot the laptop, and check how the Internet via Wi-Fi will work.

Internet may drop due to driver issues

If the Wi-Fi adapter driver is outdated, or the wrong driver is installed, then a variety of problems with the wireless connection may appear. Open device manager as I showed above (press Win + R, and execute the command mmc devmgmt.msc). Open a tab Network adapters. Find your wireless adapter (name will be "Wi-Fi", 802.11n, or "Wireless"). There may be a yellow exclamation mark next to the adapter. This means that the device is not working properly.

Even if there is no warning icon, try updating the driver for this adapter. Perhaps this will solve the problem with turning off Wi-Fi. Just update not through device manager (the system will say that the update is not needed), and download the driver from the official website of your laptop manufacturer. Required for your model and your operating system. Download and install the driver. I wrote in more detail about installing the driver in the article.

Still, you can try to select one from the already installed driver versions, remove the driver, or roll it back. I described all these actions in more detail using the example of Windows 10 in a separate article:.

What to do if the Internet periodically disappears on all devices?

If your Internet connection disappears simultaneously on all connected devices, then the problem is already in the router. I wrote about it at the beginning of the article. On computers, the connection status becomes "no internet access".

And on mobile devices (smartphones, tablets) the internet just stops working. And after such failures, you should always restart the router, only after that the Internet starts working again. Moreover, such breaks usually occur at times when the router is under heavy load: we are downloading something (especially from torrents), watch online videos, play online games, connect some other devices to Wi-Fi, etc. And basically, this problem is observed on inexpensive routers.

This is understandable, they simply can not withstand the load, and "fall". Saves only reboot. My friend has exactly the same (which is from Kyivstar provider). After connecting the smartphone and laptop, everything works well. Just turn on watching online video, after a while the Internet disappears.

What can be done:

  • Connect the Internet without a router, directly to the computer, and check the operation. To eliminate breaks on the provider side.
  • Updating the firmware of the router, this very often helps. We have instructions for all popular router manufacturers on our website.
  • Disable torrent clients on devices (if any). They create a load, due to which the Internet disappears.
  • If you have Internet through a 3G / 4G USB modem that is connected to a router, then such breaks most likely occur on the provider's side.
  • Well, buying a more powerful router.

It seems to have missed nothing. Write in the comments how you managed to get rid of this problem.

Wireless Internet is very convenient, modern, but it is not always problem-free. Some failures that cause a lot of trouble for users occur on their own time after time. Today we will talk about why the Wi-Fi network disappears. As a rule, such incidents are relevant for laptops, which, it would seem, are simply designed to work specifically with wireless networks, supporting the idea of ​​​​creating an ideal mobile solution.

Diagnosis of causes

Since there may be several causes of the problem, we will consider each separately below. In general, to begin with, you will need to do some diagnostics and check if there are any problems with the power supply of the router and the device itself. In the case of the first, everything is determined quite simply, to check the second, you need to try connecting other devices to the network - tablets, phones.

If everything works fine, it is possible that the problem is only with the computer, and you need to consistently check the operation and settings of its adapter.

energy saving

The next thing we should do if the Wi-Fi network is lost is to diagnose using the system. Click on the wireless network signal icon and find the item "Diagnosis of problems", and then follow the instructions. Perhaps this option will help you.

Open "Start" and in it find the "Control Panel" we need. Now we need the settings that are hidden under the Power Options icon.

There will be several options here, and if you do not want to set high performance, then you need to select at least "Balanced mode".

In case of unacceptability and this option, you can only set the consumption separately for the adapter. Click "Setting the power plan" next to the desired option.

Now "Change advanced options".

Here we scroll down and find the “Adapter Settings” item - you need to open the parameter tree, then open the “Energy Saving” sub-item again and set “Maximum Performance” in the “Battery” and “Network” parameters.

Everything that could be done here, you have done - now click "OK", "Save changes" and close the window.

The second option also, in a sense, depends on the power settings - it happens that when the user sends the computer to sleep, after turning on the adapter still remains in this mode.

Click "Start" again and click on "My Computer" and select "Properties".

Inside it will be a lot of equipment, but we are interested in network adapters. Having opened the tree with them, we are looking for the one with the Wi-Fi attribute and double-click the left mouse button.

Here we are looking for "Power Management" and uncheck the box "Allow the device to turn off to save power." Next, click "OK" and test how everything works. To be sure, the best option is to reboot the device after all these operations.

Sometimes the problem may be in the oxidation of the adapter contacts, not connecting it after cleaning or repair, or in the device drivers. In the first two cases, only mechanical intervention will help. To update the drivers, you need to find the name of your model and go to the official website of the manufacturer to download the necessary programs.

This is all that could be done on the computer side if the Wi-Fi network was lost, and now we will consider solving the problem on the side of the distributing point.

If the reason is in the router

If, after all the checks, you came to the conclusion that the problem is with the distributing device, then you can’t do much here: when the router is turned on and working normally, even without special settings and the provider’s cable plugged in, the network will be determined and should not disappear.

I bought a D-Link DIR-651 router, set everything up according to the instructions and ran into a problem that when the computer and power are turned off, the router resets the DNS server settings.

Foreword ... Solution of the problem with the router (router), see below ↓

It all started with the fact that I first connected the router via LAN to a desktop computer. I wrote down everything I needed, the router turned on and started working, the Internet appeared, and I was delighted. Then I thought that I should check the Wi-Fi.

I turned on the laptop, he himself found a wireless connection to the router, connected everything, the Internet started working, and the sites began to open. Well, I also decided to check the wireless Wi-Fi connection from my phone and tablet. And everything turned out well there, the connection was successful, and the Internet appeared.

The next day, turn on the router, then a laptop, and ! Or rather, writes that the network without access to the Internet. There is a wireless connection itself, Wi-Fi is working and the network is connected, and in the corner near the clock, the icon is drawn that "a network without access to the Internet."

At first I thought it was a problem with the ISP. I think as a copywriter - logically, you need to turn on your desktop computer and see if there is Internet there! I turned on the computer that is connected via LAN to the local network - the Internet is working.

Why on a laptopWi-Fi network disappears?

I bought a D-Link DIR-651 router, set everything up according to the instructions and ran into a problem that when the computer and power are turned off, the router resets the DNS server settings. Foreword... Solution...

Some laptop users periodically complain that Wi-Fi disappears on their device for no reason. It is worth noting that the problem is not just in the loss of access to the Internet, but in the loss of connection to the router's Wi-Fi wireless network. Moreover, this can happen quite often during the day, according to the reviews of many laptop owners.

If you are facing exactly the same problem, then know that in this article we will look at possible causes and solutions for it.

Wi-Fi signal range of the router

So, let's try to find out what's wrong with Wi-Fi on your laptop. First of all, we recommend that you check the signal strength from your Wi-Fi router. Think about whether your laptop is too far from the router, as this may be the reason for the ever-disappearing network. You may be constantly losing connection to your Wi-Fi network due to the fact that your laptop is physically far from the router's capture zone. The Wi-Fi adapter can and does catch on to a weak signal, but then it weakens so much that the connection can no longer be maintained. Also, do not forget that various obstacles in the form of walls, furniture and various household appliances can affect the propagation of the router signal.

Changing the distribution channel of the Wi-Fi network

Like, experimented with the signal range, but the wireless network still disappears on the laptop? Okay, then let's move on. Another reason why you may lose Wi-Fi on a laptop is interference or a busy wireless network distribution channel. By default, in the settings of any Wi-Fi router, there should be an automatic selection of a channel for distributing a Wi-Fi network. However, perhaps this is where the problem lies. You need to log into your router's control panel and try setting a different channel for your wireless network.

To enter the control panel of your router, you need to connect it to your computer using a network cable, and then enter the address indicated on the Wi-Fi router or on its box into the address bar of the browser. For example, quite often you can open the control panel using the address http://192.168.1.1 or http://192.168.0.1. After opening the control panel, go to the wireless settings and find the channel setting for Wi-Fi. If you have automatic channel selection, then try setting some static one from the drop-down menu. If they are static, try using automatic selection.

Save your settings and see if the Wi-Fi situation on your laptop has changed. If yes, then leave the channel settings set in the router control panel and safely use the connection on your laptop. If there are other devices, make sure they also connect normally to the router's network. However, if your laptop Wi-Fi adapter is still constantly disconnecting from the wireless network, then it means something else is at fault.

Disabling power saving mode

Another reason why your laptop is constantly disconnecting from the wireless network can be the power saving mode that is set in your power plan settings. Your laptop may be unplugged while in power save mode. So, right-click on Start and select "Power Management" from the context menu.

After opening the power settings window for the system, click on the link "Advanced power settings". In the next window that opens, you can see which scheme your laptop is running on (you could choose different power schemes through the battery icon in the notification bar). Select the power plan you want, and then click on the "Set power plan" link.

In the window with the options to turn off the display and sleep mode, click on the link "Change advanced power settings". A small window will open with a list of power options, among which you need to find "Wireless Network Adapter Settings". Open this setting by clicking on the plus icon on the left side, and set the value to "Maximum performance". Save the change in laptop power settings. You just have to uncheck one box in the Wi-Fi adapter settings.

Click on the keyboard Windows+R to invoke the Run utility. Next, enter the command devmgmt.msc and press Enter to open Device Manager. A window will open in front of you with a list of all the equipment present on your computer. Expand the "Network adapters" section and find your Wi-Fi adapter in it. Right click on it and select "Properties".

Here you need to go to the Power Management tab, as you might have guessed. All that remains for you is to uncheck the option "Allow the computer to turn off this device to save power." Once everything is done, save the changes made and restart your laptop. Now test your wireless network connection.

Reinstalling laptop Wi-Fi adapter driver

Well, are there any results? Does your laptop stay connected to the network for a long time? Well, if the problem still remains, then we have only two options left: the driver for the Wi-Fi adapter is not functioning correctly, or the device itself has been damaged. Finally, you have to test the theory with a bad driver for the adapter, but if nothing changes after that, you will have to go to a service center or buy a new adapter.

So, let's try to reinstall the driver for the Wi-Fi adapter. Fortunately, this is extremely easy to do. First you need to find a driver package for your Wi-Fi adapter on the Internet, for example, you can do this on the official website of the laptop manufacturer. Once you've downloaded the driver, save it a bit for later, as we're now going to uninstall the driver for the Wi-Fi adapter.

Open Device Manager as shown above and open Network Adapter Properties. Go to the "Driver" tab and click on the "Remove Device" button. As soon as you click on this button, your Wi-Fi adapter will disappear from the list of devices. Close the Device Manager window and return to the downloaded driver. Run the driver installation, wait for the installation to complete, and then restart your computer.

Try connecting to the router's wireless Wi-Fi network and see if your laptop disconnects from it. Quite often, a problem of this kind arises precisely due to the fault of the driver for the Wi-Fi adapter, which, for some reason, began to work extremely unstable and with a bunch of failures, for example, it can cause constant interruptions in Internet access or even disconnect from the wireless network .

We hope that reinstalling the driver was able to fix your problem. However, if the laptop still keeps disconnecting from the wireless network, then, as we suspected, something is definitely wrong with your Wi-Fi adapter. As already mentioned, in this case, contact technical specialists or buy an external Wi-Fi adapter.

Found a typo? Select the text and press Ctrl + Enter

I recently discovered that on my new Windows 8 laptop. The first thought was: “Why is Wi-Fi buggy, because everything is fine on the other laptop?”. In the end, I just turned Wi-Fi off and on again, but then I noticed that it shouldn’t be like this and I have real problems with Wi-Fi on my laptop.
I immediately entered into the search: "", and as a result I received a million forums where everything was blurry. After thinking for a bit, she added: why does wifi turn off on laptop", but here everyone kept saying that set up a router. In the end, I gave up and began to look for a solution to the Wi-Fi problem on my laptop myself.

Why does WiFi turn off on a laptop, what are the options?


In case you just then it's too early to worry. It is possible that WiFi on your laptop is constantly turning off due to a poor Internet connection. Another reason why WiFi is turned off on a laptop may be that there are too many obstacles between the laptop and the router. But if you notice that you , then there may be other reasons:

  1. Perhaps the Wi-Fi on the laptop disappeared due to a violation of the connection to the DNS server.
  2. , it is easy to check the Internet through another laptop or smartphone.
  3. Perhaps Wi-Fi is disconnected on the laptop due to a defective module.
  4. Or maybe you just have a power saving mode, which is why WiFi on your laptop is constantly turned off in order to save battery.
  5. The drivers on your network adapter are outdated and therefore WiFi periodically disappears.

The first three options are easy enough to check if you have a second laptop or tablet with Wi-Fi. In my case, the problem was in point 4.

Wifi keeps disconnecting on my laptop, what should I do?

The solution to my problem, why the Wi-Fi on the laptop disappeared, I outlined in detail in a step-by-step instruction with a photo:








Method 2. How to fix the problem if Wi-Fi is turned off on a laptop?

There is a second way to solve if WiFi is constantly turned off on a laptop:



What to do if Wi-Fi is still disconnected on a laptop?

If your WiFi periodically disappears, you need to update the drivers, you can do this in the same place by going to the properties of the network adapter:
