Almost every modern laptop has a built-in Wi-Fi module that allows you to connect wirelessly and create your own access points. Users have cases when Wi-Fi is turned off on a laptop. Below will be described methods that allow you to understand the cause of the problem, and then fix it.

It is worth noting that the problem can have two directions: software and hardware. Software includes various adapter settings in a laptop, router, and Windows. The hardware most often refers to a physical malfunction of the device. And it also happens on any version of the operating system, be it Windows 7 or Windows 10.

Reasons for turning off Wi-Fi on a laptop

When working on a computer, there are cases of spontaneous disconnection of Wi-Fi. As a result, the Internet disappeared on all devices or only on the laptop. This is not necessarily a critical error, there may be other reasons:

connection with the router is interrupted due to a weak signal;
the network is turned off to save energy;
failure on the driver side;
interference due to various devices;
physical failure of the Wi-Fi module.

Video - why Wi-Fi turns off:

The first few phenomena can be easily eliminated. As for the physical malfunction, it is necessary to find a suitable module and replace it.

Energy saving settings

The quickest way to try and fix your Wi-Fi issue is to go into the power plan settings on your laptop. The point is that when going into sleep or hibernation mode on some laptops, the system may turn off the Wi-Fi module. The same thing happens in the Power Save mode, where many computer components operate at reduced frequencies. If your laptop model turns off the Wi-Fi adapter itself when saving power, then you can configure the parameter accordingly as follows:

Open the Run window using the Win+R keys.
Enter the command "control powercfg.cpl".
A window with power settings will open. There we select the option "High performance". Or, in the already installed mode, click on the item "Setting the power plan".
In the window that opens, click on "Change advanced power settings".
We find the option "Wireless Network Adapter Settings".
In the next step, we find the section "Power saving mode" and change it to the item "Maximum performance".
We save the settings.

Thus, the wireless adapter should not be disconnected periodically. If this problem persists, move on to other fixes.

Low reception signal and interference

When connected to a router other than your own, you may notice a weak signal level, due to which Wi-Fi flies. This can be seen on the network icon and the number of sticks that are responsible for signal strength. Of course, even with poor reception, the connection can be stable, but at some point, the connection may break due to interference from other wireless devices.

In other words, interference may occur due to the presence of the following objects and phenomena:

The power grid is unstable;
metal objects located near the signal receiver and transmitter;
thick walls, due to which the network is constantly disconnected;
devices that emit waves of different frequencies make the Wi-Fi connection unstable.

The easiest way to get rid of this problem is to put the device, in our case a laptop, closer to the router and remove all kinds of objects that are objects of interference.

Changing properties in Device Manager and reinstalling the driver

This option is also very simple. You can restore Wi-Fi on a laptop using some task manager settings that need to be changed in the energy saving section, and we will also try to reinstall the Wi-Fi adapter driver. Now you need to perform the following series of actions:

In Windows 10, press the combination Win + X and go to the device manager. Perhaps you have the Windows 7 operating system installed, then open the Run window using the Win + R combination and enter the following: devmgmt.msc.
Open the "Network Adapters" section and look for something like this "Wi-Fi Adapter".
Go to its properties using the right mouse button.
Switch to the "Power Management" tab, uncheck the "Allow the computer to turn off this device to save power" option.

Steps to reinstall the driver:

An unsuccessful attempt could also occur, which means that Wi-Fi periodically turns off again. Then we try to remove the driver, and restart the computer. It usually reinstalls itself automatically. In addition, install the already downloaded driver.

Now, when the router loses the network, the above software methods will fully help to get rid of the problems that have arisen. Now, as for the router.

Problem in the router

When a user is not connected to their own network, fixing the problem can be several times more difficult. Having your own router, you can at least restart it. The wireless network crashes for the reasons described below.

Note that many modern budget-type routers often hang and Wi-Fi turns off. This problem occurs due to increased network load, for example, when a user downloads large files via torrent.

Power outages are a known cause. Eliminating the phenomenon is not always easy, but it is recommended to restart the device, then disconnect it from the network for a few minutes.

Another option is when several devices work on the same channel. What to do in this case? Change the settings from the router control panel, where you need to change the channel number to a free one.

Additional actions:

connecting an Internet cable directly to a computer or laptop;
updating the software (firmware) of the router;
temporary refusal to use torrent programs;
using another router.

All the options discussed in most cases help fix problems with Wi-Fi disconnecting every 5 minutes. If one method does not help, go to another and so on.

Now the user should not have a question why the Wi-Fi connection is disconnected on the laptop

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.

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 there, in the “Battery” and “Main power” parameters, set “Maximum Performance”.

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".

There will be a lot of equipment inside it, 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.

As mentioned above, check the power of the device - perhaps the contact is loose somewhere or the power supply is becoming unusable.

The problem may lie in the firmware that has flown down, but it’s quite difficult to identify this, because in the event of a failure you can get into the settings and visually everything will be fine, but the Wi-Fi network still disappears over and over again.

In any case, if the router is already malfunctioning, flashing it is unlikely to harm it. Just go to the official website of the manufacturer, open the instructions and download the firmware. If after that there are no improvements, then most likely you will have to go for a new router.

Setting up a Wi-Fi router is not so difficult, however, after that, despite the fact that in general everything works, a wide variety of problems are possible and the most common of them include the loss of a Wi-Fi signal, as well as low Internet speed (which especially noticeable when downloading files) over Wi-Fi. Let's see how to fix this.

I will warn you in advance that this instruction and solution do not apply to situations where, for example, when downloading from a torrent, the Wi-Fi router simply freezes and does not react to anything until the reboot. See also - all articles (problem solving, setting up different models for popular providers, more than 50 instructions)

One of the most common reasons for a Wi-Fi connection to drop

First, about exactly how it looks and specific symptoms by which you can determine that the Wi-Fi connection is disappearing precisely for this reason:

A phone, tablet or laptop sometimes connects to Wi-Fi and sometimes doesn't, with almost no logic.
The speed over Wi-Fi, even when downloading from local resources, is too low.
Communication with Wi-Fi disappears in one place, and not far from the wireless router, there are no serious obstacles.

Perhaps the most common symptoms I have described. So, the most common reason for their appearance is that your wireless network uses the same channel that is used by other Wi-Fi access points in the neighborhood. As a result of this, due to interference and “clogging” of the channel, such things appear. The solution is pretty obvious: change the channel, because in most cases, users leave the Auto value, which is set in the default router settings.

Of course, you can try to perform these actions at random, trying different channels until you find the most stable one. But you can approach the matter more reasonably - to determine in advance the most free channels.

How to find a free Wi-Fi channel

If you have an Android phone or tablet, I recommend using a different instruction:

First of all, download the free inSSIDer program to your computer from the official website http://www.metageek.net/products/inssider/ . ( UPD: The program has become paid. But they have a free version for Android). This utility will allow you to easily scan all the wireless networks in your environment and graphically display information about the distribution of these networks by channel. (See picture below).

Signals from two wireless networks overlap

Let's take a look at what this graph shows. My access point, the site uses channels 13 and 9 (not all routers can use two channels at once for data transfer). Note that you can see that another wireless network is using the same channels. Accordingly, it can be assumed that problems with Wi-Fi communication are caused by this factor. But channels 4, 5 and 6, as you can see, are free.

Let's try to change the channel. The general idea is to choose the channel that is as far as possible from any other sufficiently strong wireless signals. To do this, go to the router settings and go to setting up a wireless Wi-Fi network () and specify the desired channel. After that, apply the changes.

As you can see, the picture has changed for the better. Now, with a high degree of probability, the loss of speed over Wi-Fi will not be so significant, and incomprehensible disconnections - so frequent.

It is worth noting that each wireless network channel is 5 MHz apart, while the channel width can be 20 or 40 MHz. Thus, when choosing, for example, 5 channels, the neighboring ones - 2, 3, 6 and 7 will also be affected.

Just in case: this is not the only reason why there may be a low speed through a router or a broken Wi-Fi connection, although one of the most frequent. This can also be caused by unstable firmware, problems with the router itself or the receiver device, as well as problems in the power supply (voltage jumps, etc.). You can read more about solving various problems when setting up a Wi-Fi router and the operation of wireless networks.

In this article, we will talk about what to do if the WiFi network on a laptop turns off spontaneously. It is worth noting that the operating system is completely unimportant here, since such problems are found on XP, Windows 7 and 8. It is very important to disassemble all the reasons, since not every user is able to deal with this on their own.

Also, such problems are found on a variety of models of wireless Wi-Fi adapters. Since the point here is not at all in the manufacturer and company, but in the principle of operation and system settings of the operating system. So, to business.

The wireless connection on a laptop may turn off on its own for the following reasons:

Shutdown to save power.
Weak wifi signal.
Driver failures.

These are all the reasons why the WiFi network is turned off on a laptop. All of them are easily eliminated by making some settings or reinstalling the driver for wireless equipment. Let's analyze all the points in more detail.

Weak Signal and Sources of Interference

Very often, the reason that the WiFi network on the laptop is constantly turned off is a weak signal and various sources of interference. The fact is that, like any other radio signal, WiFi can also fluctuate. That is, the signal level is not stable.

It changes under the influence of certain factors:

Mains voltage.
Various electrical appliances that create strong interference with the WiFi signal.
Metal objects located between the signal source and the laptop.

If your computer is located far enough from the router, then the signal strength may disappear from time to time. Because of this, a disconnection from the network occurs. The fact is that the signal itself fluctuates a little. If the computer is located close to the router. That is imperceptible. However, when the signal level reaches 8-10%, such fluctuations can cause a Wi-Fi connection to break.

Also in this case, various metal objects located between the laptop and the router can cause interference. Even worse, if there is any device nearby that creates interference. For example, a mobile phone or a microwave oven. To fix this problem, simply move the computer closer to the WiFi router.

Disabling the WiFi adapter to save power

In a laptop, one of the most important factors is its autonomy. Therefore, the developers have created a program to save energy. According to it, if you do not use any module for a certain time, then it will automatically turn off. Also with the Wi-Fi connection adapter. It may spontaneously turn off if you do not use it.

But there are also such cases that the program does not work quite stably and the connection regularly breaks at certain intervals, regardless of whether you use the Internet or not. In this case, you just need to disable this feature on the laptop.

To do this, click on the battery icon in the tray (lower right corner of the desktop). Select "Advanced power options" from the menu that appears.

A window will open where you can select a power plan. Here you need to enter the "Power Plan Settings". We are interested in the parameters of the type that you are using (it is better to do the following steps for all types).

So, now click "Change advanced power settings". In the simple window that opens, find the "Wireless Network Adapter Settings" item. Open a thread. You will see "Power Saving Mode". Open it.

Now you see all the modes available to you:

From the network.
From the battery.

In both cases, select the "Maximum performance" item. This means that the WiFi adapter's automatic power-off feature to save power is disabled. This will keep your wireless module from being disabled.

You have done the above steps, and WiFi is still disconnecting. This suggests that your operating system is also set to save power. In order to disable this feature, you should open the Network and Sharing Center.

This is done by right-clicking on the WiFi network icon in the tray. Next, select the appropriate item. In the window that opens, we are interested in the "Change adapter settings" section. Here we simply find the shortcut for the wireless network (or wireless network connection) and right-click on it. Select "Properties".

This will open the menu. We are interested in the "Network" tab. In it, click the "Configure" button. Next, select the Power Management tab. Here you just need to uncheck the box "Allow the computer to turn off this device to save power." Click OK and close all windows.

Checking the performance of Wi-Fi hardware drivers

Why does the WiFi network turn off on a laptop? The above steps did not help, what should I do? This indicates that the hardware drivers are not working correctly. In order to check this, press the key combination Windows + R, in the window that appears, write the following command - mmc devmgmt.msc and press "Enter". This will open Device Manager. Here we are interested in " Wireless adapters". Open the branch and check if any module is highlighted with an exclamation point . In addition, the name of the wireless equipment must include its name and full model, for example, Broadcom 802.11n Wireless Network Adapter. If you just have "Wireless Equipment" or "Wireless Network Adapter" written, then you should update the driver.

Also, a failure can occur as a result of power outages or due to a large number of subscribers. All these reasons give one effect - the router freezes. To fix it just restart it. Unplug the WiFi router's power supply from the outlet for 7-10 minutes, then turn it on again. Unfortunately, this phenomenon cannot be completely eliminated, since budget devices are simply not able to withstand high loads without negative consequences, and at some point they will still fail.

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...

As practice shows, the biggest problems for users when working with Wi-Fi and routers are not caused by the connection process and not even the setup process. The biggest problem is the moment when, after setting up, the Internet regularly disappears, a message about an interrupted connection constantly pops up, or you just can’t open a single site on your laptop. In this article, we will try to find out what causes such problems, and what to do if Wi-Fi turns off on a laptop.

The reasons for automatic network shutdown are quite common.

What could be more frustrating than experiencing connection drops when working on a laptop? Just now everything was fine, and you calmly watched the movie online, and now the playback stopped, the movie paused, and the Internet disappeared altogether. You may encounter this problem for a variety of reasons. The most common are the following:

Your laptop is in battery saver mode. This leads to the fact that after a set period of time when the device is completely idle, the wireless connection is automatically terminated, the Wi-Fi adapter stops exchanging packets with the router and thereby saves battery power.
The router through which you access the network is too far away or there are obstacles between it and the laptop. The consequence may be a weak level of the received wireless signal, which leads to regular disconnections. This happens, as a rule, automatically and imperceptibly for the user.
The Internet signal received by the router via cable or cellular network and converted into a wireless Wi-Fi signal is too weak. At such moments, you can observe that the laptop is still connected to Wi-Fi, but the Internet refuses to work. Also, a weak signaltransmitted over the cable may cause the wireless connection of the router and laptop to turn off automatically.

The router through which you access the Internet is unstable, constantly freezes, spontaneously reboots. In this case, Wi-Fi in your laptop is automatically turned off until the router is turned on again, its software is restored, or until a forced reboot.
Your laptop has an incorrect or outdated wireless network adapter driver. As a result, the operation of the adapter becomes unstable, and it may spontaneously interrupt the connection or not find available networks at all.

Here we have listed only the most common problems that users regularly encounter. But at the same time, many do not know what to do next and how to get rid of problems.

Battery saving mode

We definitely recommend that you first check if the power saving mode is activated on your computer. This is a built-in feature of the Windows operating system that monitors how you use (or do not use) certain elements of the system and certain components of the PC. If any of them is idle without work for a long time, it is automatically turned off by the system. Windows does this in order to save battery power, which is sometimes the only source of power for a laptop.

To disable battery saving by interrupting the wireless connection, you need to open the Control Panel of your PC, find the Power Options category and select the Power plan setting that is currently installed on your system by default. Everything you need is under the Change advanced power settings link. In the small system window that opens, go to the following path: Wireless network adapter settings > Power saving mode and change the values to Maximum performance. Click Apply and close all windows. This procedure will get rid of the situation when the Internet is turned off at the request of the operating system.

Weak router signal

Generally, a weak signal coming from a Wi-Fi router can be the reason why the connection to the network regularly disappears. Since the signal of the router is the most common radio wave, a variety of factors affect its power, which can also affect the quality of the connection. Not always the remoteness of the laptop from the router is the main reason for the decrease in signal strength. These may be additional barriers located between the receiver and the wireless signal translator. For example, in a large room consisting of several rooms or offices, the walls separating the laptop and the router can significantly reduce the quality of the connection. In such cases, it is worth considering revising the location of the router or expanding the network radius with the help of special amplifiers.

Also, the quality of the connection may be affected by the presence of electrical appliances that involuntarily interfere with the propagation of radio waves. As a result, the display regularly shows an error about the loss of connection.

Metal objects between the Wi-Fi router and the laptop also significantly reduce the stability of the connection on the wireless network through which you access the Internet. Keep this in mind when organizing your home LAN.

Weak network signal

If the signal from your ISP via cable or cellular network is too weak, the router may become unstable, turning off the access point and losing connection with devices connected to it. In such a situation, it is better to contact the provider's support service, describing in detail the essence of the problem. If we are talking about a mobile router and its operation in places of uncertain signal reception, where a message about searching for a network is displayed on the display of the router or mobile device, an external antenna can improve reception quality. To clarify information about network coverage of specific settlements, you should also contact the representatives of the provider.

Unstable operation of the router

If you observe unstable operation of the router, which leads to a regular disconnection of the wireless connection, we recommend that you restart the device several times and closely monitor its further work. Or go to its control panel, check for software updates and install them if necessary. Since the router is running a special operating system, it, like any other, can accumulate system errors, work not quite stably and require periodic updates.

A complete reset of the router may also help. We recommend doing this only if you know its settings for your provider and can configure it again after the reset. Otherwise, contact the provider through the official website or by calling the hotline.

Driver failure

If the driver for the wireless network adapter has not been updated in your laptop for a long time, or if you began to observe problems with disabling Wi-Fi after the last reinstallation of the operating system, it may well be that an outdated or not the most suitable driver is installed. We recommend that you find out the manufacturer of the network adapter installed in your laptop and download the latest driver. We recommend doing this without fail on the official website of the manufacturer.

Conclusion

Whatever the reason for your laptop's Wi-Fi dropping out, one of these troubleshooting steps can help you get your network back to normal. If you tried all the instructions in this article, but none of them helped to identify the cause and get rid of the problem, you should contact the service center to test your router and network adapter in your laptop, as the problem, apparently, lies somewhat deeper.

Hello, friends. If you have problems with the operation of a Wi-Fi 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 the operation of the 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 have stopped connecting to the Internet via Wi-Fi, or the Internet via Wi-Fi often breaks, 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.

An even more interesting case, which I also met in the comments, is when the Internet is working, and at one point 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 parameter (Channel:) 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 via a 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, I think that the process of changing the Wi-Fi channel is not much different.

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 setting up a Wi-Fi network 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.
