Why does the Internet turn off when I turn on Wi-Fi. Unstable Internet operation over Wi-Fi: some tips to solve the problem

All tips

Thanks to wireless routers Using the Internet is much more convenient. Wires do not get tangled underfoot, and the laptop can be installed in any convenient place. However, sometimes the connection begins to act up, which causes great sadness for people who are used to spending a lot of time on the Internet. Why does the Internet on my laptop disappear via WiFi? How to determine what exactly is the cause of the malfunction? Can I solve the problem myself? Let's take a closer look at what to do if WiFi on your Windows laptop 7 or 10.

How to find out that the problem is in the router

First of all, the “prime suspects” must be ruled out. Therefore, if WiFi is lost on the laptop, you need to try connecting to wireless network using any other gadget. For this you can use mobile phone, game console or tablet. If there is no wireless network signal on any device, then we can confidently say that the problem lies in the router itself.

Based on this, it is easy to come to the conclusion that in a situation where the Internet will work properly on third-party gadgets, the cause of the breakdown is related to the operation of the laptop computer.

Laptop problems

If the router works well, then you should switch directly to computer equipment. On a laptop, the Internet via WiFi disappears in this case for several reasons. If the laptop does not see any available connections at all, then it is recommended to check whether the wireless module is disabled on laptop computer. As a rule, the operation of this unit is indicated by a corresponding light indicator located on the laptop body. If the light is not on and WiFi has disappeared on the laptop, then you need to connect the module yourself.

To do this, click certain combination keys (usually Fn+F2, but it all depends on the device model), after which the required node will be forced to turn on. Also on some modern laptops The button for turning on the wireless connection is located on the laptop body. In this case, you need to find it and click.

On some laptops it is completely absent. What to do in a situation where WiFi on a Windows 10 laptop is lost? In this case, you need to go to the section called “Networks and Internet”. Next, just find the wireless connection tab and see if the corresponding module is enabled.

What should those who lost WiFi on their Windows 7 laptop do? In this case, the described method will not work. Then you can connect an external keyboard to the laptop’s USB connector, which has the coveted Fn key. If you don’t have such a device at hand, then it is recommended to use a little trick. Every system has an on-screen keyboard. To activate it, just click on the “Start” button and enter the corresponding query in “Search”. After that all you have to do is click on on-screen keyboard combination with the Fn button.

If the problem occurs after reinstalling Windows

If WiFi has disappeared on your laptop, it’s worth remembering your latest actions. The OS may have been recently reinstalled. In this case, sometimes all default settings are reset.

To correct the current situation, it is necessary to hardware enable. It is performed using the same technology for all versions of this OS. To connect the network module, just:

Go to “Network and Sharing Center”.
Select "Change settings".
Find in the list that opens desired name wireless network and right-click on it.
Select “Enable” in the list that opens.

If after these manipulations the situation has not changed, then perhaps in order to answer the question “Why does WiFi disappear on the laptop?”, you will need to check the functionality of the router drivers. This is a fairly common problem that can occur at any time for no apparent reason.

Checking the Wi-Fi driver

Regardless of the laptop brand, after connecting the router for the first time, the corresponding software. Based on this, it’s easy to guess that the router should be in the list of devices in the “Device Manager”. It will appear there regardless of whether the drivers are correct. To update them, you just need to perform a few simple manipulations:

Click on “My Computer” with the right mouse button.
Select “Management” from the drop-down menu.
Go to "Device Manager".
Find the section called “Network Adapters” and find the router you need.

As a rule, a warning sign is displayed next to a module that is not working correctly. In this case, you need to click on it right click mouse and update the current drivers.

Usually the system finds them in automatic mode through the Internet. However, when the WiFi on the laptop is lost, this will be somewhat difficult to do. You need to download drivers from the manufacturer's official website using another device. After this, you should save the files on your computer and try going to Device Manager again. Only in this case it is advisable to choose not automatic search drivers, but indicate the address that will lead to the folder with the downloaded files.

Antivirus

This problem is extremely rare, but it should not be ruled out. Some antivirus programs check the strength of the router's signal encryption and conclude that it is weak. In this case, the antivirus may block the module for security reasons. Therefore, it is recommended to add the router to the exceptions. Or you can try disabling the antivirus for a few minutes and connecting to the wireless network again.

Obstacles to the signal

In the case where there is no connection to the network since moving to new apartment- most likely, something in the room is blocking the wireless waves. If the router is installed in a separate room, then perhaps the walls are too thick for signal transmission or the reinforcement elements are too massive.

Everyone knows that the level of communication quality is indicated by a triangular icon with several dots on it. The more there are, the better the signal. Therefore, after moving, it is recommended to pick up the laptop and walk around the apartment with it. If only 1-2 marks are displayed in any place on the screen, it is better to stay away from that area. Here the signal will be simply disgusting.

In addition, you should avoid other obstacles between the laptop and the router. Therefore, it is not recommended to place the router behind a TV or microwave oven. However, sitting too close to the router is also not advisable. This can also negatively affect signal strength.

If all else fails

When everything has been tried, all that remains is to use the simplest remedy, which often helps in a wide variety of situations - reboot the computer and the router itself. In this case, the router needs to be disconnected not only from network cable, but also unplug it from the power supply. After restart Internet distribution will not start immediately, so you should wait a little.

You need to check with your Internet provider to see if there are any renovations going on in the house. This may also result in signal loss.

Let's consider today the problem when the Wi-Fi network is unstable, and when the connection to the Wi-Fi network is periodically interrupted, or the Internet connection is lost. It seems to me that this is even worse than when the Internet does not work at all. Because the problem is not clear, everything seems to work, but not as it should, the signal disappears, devices turn off, and other incomprehensible moments. It’s just that when something doesn’t work, it’s at least clear where to look for a solution, but in such a situation nothing is clear at all.

What causes an unstable Wi-Fi connection:

Periodic disconnections of devices from the Wi-Fi network. Or the Internet simply breaks for a while (), and everything starts working again. A very popular problem that causes a lot of inconvenience. For example, a laptop is connected to a Wi-Fi network, and the Internet is working. But periodically a yellow one appears near the connection icon Exclamation point, and the Internet disappears. Loading files gets stuck, etc. And, as a rule, the connection is restored after a while.
Devices do not connect to the Wi-Fi network the first time, or do not see the Wi-Fi network.
The Wi-Fi network completely disappears and appears.
Very low speed Internet via wireless network (everything is fine via cable).
When the Wi-Fi connection only works close to the router.
The wireless network signal level is constantly changing.

This, of course, is not the entire list of problems that are associated with unstable operation of wireless networks. There may be many more. Very often, Wi-Fi works fine for a while, and then problems begin and go away again. You may also notice the appearance of problems, for example in the evenings, or at other times of the day.

If you have something similar, and you seem to have an Internet connection, but you can’t always use it ( use without any problems), then now we will try to fix everything.

Changing the wireless network channel when Wi-Fi is unstable

This is the first and most important tip that you should definitely try. We know that every Wi-Fi network operates on some channel. If there are many of these networks, then they begin to interfere with each other, and interference appears. As a result, Wi-Fi is unstable. Well, and various incomprehensible problems that I wrote about above, and which you have most likely already encountered.

Need to change Wi-Fi channel network in the router settings. Details about channels, about finding a free one and about changing to different models routers, I wrote in a separate instruction:

You can try asking some static channel (if you have Auto), or vice versa, set Auto if a static channel was selected. In the article linked above, I wrote about finding the freest channel using the inSSIDer program. You can use it.

You just need to go to the router settings, go to the tab where you configure the wireless network, and in the Channel item change the channel. This is what it looks like on Tp-Link routers:

And on Asus routers:

After each channel change, do not forget save the settings and reboot the router. Be sure to try several options. It should help.

As for interference, it can be created Appliances. Do not place the router near microwave ovens, cordless phones, etc.

The Internet is cut off via Wi-Fi: router firmware, and other tips

Almost always, such problems in the wireless network occur due to the router. Not rarely, this is due to the firmware. Therefore, I strongly recommend updating the firmware of your router. We have instructions on our website for all popular manufacturers. Here's an example:

It is also possible that the wireless network may be unstable due to some technical problems with router. Something with the board itself, or the power adapter. By the way, it is power adapters that very often cause such problems. The router just doesn't receive proper nutrition and connection breaks appear, etc. Well, strong changes in the power supply can affect the operation of the router. If the Internet goes out after you put some kind of load on the router (online videos, games, torrents, connecting new devices, etc.), then this is usually due to an inexpensive (not powerful) router.

Need to eliminate problems on the ISP side. It may well be that the connection is broken on its end, and the router has nothing to do with it. It’s very easy to check, just connect the Internet directly to your computer and check its operation.

For many people, the connection breaks down in those rooms where there is very bad signal Wi-Fi networks. When, for example, only one division of the network signal remains on the device.

In such a situation, you need to increase the range of your Wi-Fi network. We have an article on this topic:. Or, install . After this, problems with Internet interruptions should disappear.

And if you find a lot of devices at home available networks, which operate at 2.4 GHz (as is most likely your network), and changing the channel, and even changing the router does not produce results, and the Wi-Fi network is very unstable, then this problem can be solved by purchasing a router that supports operation at a frequency of 5 GHz. This frequency is practically free. I just know a case where there were a lot of wireless networks in the house, and Wi-Fi was simply impossible to use until they switched to the 5 GHz frequency.

If the Internet disappears on only one laptop

And of course, it’s not uncommon for all devices to connect and work with a wireless network without any problems or disconnections, but one device keeps disconnecting, losing connection, etc. It’s not hard to guess that most often this device is called a laptop and runs on Windows.

In such cases, it is imperative to update the wireless adapter driver. I wrote how to do this. It is possible that the problem may be in the hardware. And it appears very often after disassembling the laptop (cleaning dust). Why is that? During assembly, the antenna that is built into the laptop often suffers. These are the problems with working with Wi-Fi networks. Very often, after this the Internet only works near the router itself.

Update: changing Wi-Fi network properties

Open Network and Sharing Center shared access" and click on your Wi-Fi network. In the new window, click on the "Wireless network properties" button and check the box next to "Connect even if the network does not broadcast its name (SSID)". Click Ok.

If it doesn’t help, and Wi-Fi continues to fall off, then in the same window, on the “Security” tab, you can click on the “ Extra options" and check the box next to "Enable Federal Information Processing Standard (FIPS) compatibility mode for this network."

You can restart your computer. Thanks to Alexander for this advice. He suggested it in the comments to this article.

Here are some tips if you have any: interesting information on this topic, personal experience, then write in the comments. You can ask questions there, I will definitely answer!

Happy laptop owners sometimes experience situations when wifi suddenly turns off and the Internet no longer works. This problem is not uncommon and can constantly arise due to completely various reasons. This publication will discuss ways to solve such a problem.

Imagine you are reading a news article, watching an online movie, communicating with friends in instant messengers or through voice communication when suddenly access to the Internet is disconnected, the computer stops seeing available connection, and its resumption constantly wastes precious minutes, which are always in short supply. In this regard, before starting to solve the problem turning off wifi, it is worth understanding some of the reasons leading to this error.

The most common reason for periodic disconnection of Internet connection lies in system utility laptop energy saving. The program, after certain periods of machine inactivity, breaks the wireless connection due to which the Wi-Fi module stops seeing and exchanging data with the router in order to save energy.

An unlikely, but valid reason is that the access point is located too far from the device receiving the signal or operates behind an obstacle. As a result, the signal strength becomes so weak that wireless adapter The laptop is not able to catch it, as a result the connection is disconnected. This is why it is so important to purchase devices with a powerful transmitter.

Often, the Internet signal transmitted via cable and converted in the router into demon wired connection, too weak and, despite working Wi-Fi modules, access to the network is impossible. Besides, weak signal cable connection may cause automatic shutdown connecting the access point and laptop.

Unstable wifi work router, which periodically manifests itself in reboots and freezes. In such cases wireless device the computer will do automatic restarts, and the connection will disappear, disconnect and resume again after full recovery operation of the access point.

Outdated or inappropriate wireless adapter driver wifi connections laptop also leads to periodic disruption of uninterrupted operation, or even the computer does not detect available wireless connections at all.

The problems described above are the most commonplace, but other reasons also occur and it is necessary to remember that each specific case is in some way unique and its resolution requires a whole range of measures to restore a lost connection.

Disable power saving mode

Since all laptops have built-in autonomous elements supplies, they are usually accompanied by special programs or are used standard means operating system to make energy saving efficient. To disable the power saving mode, which is implemented by disabling the wireless adapter, you need to open the “Control Panel” and find the power and energy saving icon there. In the window that opens, you need to find and select the power supply scheme setting. Next, you need to open the “Change advanced power settings” link. In the window that opens, open the adapter settings wireless connection, find the “Power Saving Mode” icon and there, change the values to maximum performance mode, in other words, prohibit the program from turning off the wireless adapter. Now operating system will not be able to interfere with or interrupt the wireless connection.

Weak access point signal

The quality of a wifi router signal can be affected by a variety of obstacles, from room walls to electrical appliances. Often, the cause of signal loss may be a malfunction of the antenna of the Wi-Fi transmitting device.

To eliminate this problem, you should use the trial method. It is necessary to identify the cause of the constant interference, gradually moving the laptop away from the distributing access point and checking how the adapter works, because any metal objects contribute to the deterioration or loss of the radio wave signal.

Signal propagation

If you suspect a weak signal coming through the wire from your provider, then you should contact customer support and find out the cause of the problem, which is why you lose access to the RuNet. When we're talking about about the network provided mobile operator, then it may be worth making attempts to strengthen the signal by changing the location of the transmitting device.

Problems with Wi-Fi distribution device

In case of obvious problems with the wifi router, a series of reboots can help. If the device does not work as required and continues to disconnect, you can, alternatively, check the settings of the access point; perhaps the provider has changed some parameters. You can also check for updates on the equipment manufacturer’s website and, if available, update the software through the settings menu.

Driver problems

If the working machine is not the latest, then why not check for updates, perhaps you should think about installing a fresh one wifi drivers network devices. To do this you need to find out the manufacturer network adapter and download new version from its official website and then install it on your personal computer.

If any problems arise related to disconnecting Wi-Fi, you should use the above tips and only then, perhaps, it will make sense to contact a specialized service center for detailed equipment diagnostics. Now you know why wireless connection may be torn and able to find a solution to this problem.

Wi-Fi is a technology that allows electronic devices to transmit data or connect to the Internet wirelessly. Nowadays, using Wi-Fi is becoming very common and we can see this technology being used by a wide range of devices such as smartphones, tablets, game consoles, smart TVs, etc.

However, this technology has a number of limitations. Firstly, it is not as secure as a wired connection, but this is solved by using Protected Access Encryption (WPA2), which prevents unauthorized access to the network. If you do not have sufficient knowledge to set up your home or office network, then it is better to entrust this matter to professionals. Simply fill out the form at http://kompom.kiev.ua/ and the setup will be done quickly and efficiently.

Another problem: Wi-Fi drops out periodically. Usually, when there is no activity, the phone or tablet loses connection with the Wi-Fi router and does not see the network until Wi-Fi on the mobile device is restarted. There may be several reasons why the Wi-Fi connection is lost; in this article we will look at several options for solving the problem when Android loses the Wi-Fi network.

If you encounter a problem Wi-Fi shutdown on your Android device, try the following settings and you will be able to connect your device wirelessly without much hassle.

Wi-Fi network overflow

The biggest obstacles for Wi-Fi signal create neighboring wireless networks. The problem is that most Wi-Fi devices operate in the already occupied 2.4 GHz band, and high density signals can interfere with each other, reducing the speed and performance of networks.

Solution: Use a dual-band router that can operate on both 2.4GHz and 5GHz simultaneously. The 2.4 GHz frequency band will be supported by most devices, but it only has three non-overlapping channels. On the other hand, 5 GHz has 23 non-overlapping channels, increasing the likelihood of no interference in this band. If your router can operate in the 5GHz band, use it to solve your Wi-Fi network congestion problem.

Setting up a Wi-Fi channel

The 2.4 GHz Wi-Fi band has 11 channels and each of them is separated from each other by a 5 MHz band and has a width of 20 to 22 MHz. This means that each channel will overlap adjacent channels by 10 MHz and this is referred to as overlapping channels.

Solution: In the case of channels 1, 6 and 11, there will be no overlap causing interference, since these are not overlapping channels. To work on these channels, users will need to go into the router's settings and find a setting called "Channel" or " Wireless channel" From the drop-down menu, you need to select desired number channel.

Most manufacturers resort to various methods to increase battery life. Android users smartphones are forced to include such energy saving features in their devices. One such feature is turning off Wi-Fi when the phone is inactive or when the device has low level battery charge. Such Wi-Fi features in sleep mode create problems when connecting to the network as needed.

Solution: Simply configure your Android device's settings and make sure you always have Wi-Fi turned on, even when your device is not in use. To do this on devices running Android 2.3 Gingerbread and above, you need to do the following. Go to Settings menu – Wireless network– Wi-Fi and select More – Wi-Fi in sleep mode do not select “Do not turn off”.

On those devices running Android 4.0 ICS and higher, go to Settings - Wi-Fi, select Advanced and install Wi-Fi option during sleep – “Always”.

Change DNS servers

Changing DNS servers may solve Wi-Fi problem when the Internet network on the phone disappears. Go to Settings - Wi-Fi and turn on Wi-Fi. If this famous network, you will have to “forget” it and then connect it again. When you see the password entry window, click on Extra options and select “Static” from the IP settings in the dropdown menu. Then scroll down and enter the IP address of the DNS server you would like to use in the DNS1 and DNS2 field. Now enter Wi-Fi password and connect the network.

Reset to factory settings

If none of these methods help, try hard reset your Android device. If you then have problems where you lose your Wi-Fi connection, then it could be a hardware problem. You may have to take the device to a service center to have the problem fixed.

We looked at the most common reasons for Wi-Fi disconnection that occur in Android devices. We hope this will help solve the problem and allow you to set up a stable WiFi connection. In addition, please note specialized applications, because in Google store Play there are many applications, the use of which will help ensure a reliable connection. Some of them are Wi-Fi Fixer, Fix My Wi-Fi, Wi-Fi Analyzer and others.

Recently I began to notice that the more people buy different equipment with WiFi - routers, modems, access points, TVs, tablets, etc. - the more problems arise with the wireless network: the signal disappears or it is very low, the data transfer speed jumps or it is very low, devices periodically fall off and can no longer connect. There are quite a few reasons why Wi-Fi turns off, and these can be: software settings, and hardware failure. In general, a wireless network itself is a very capricious thing, the stability of which depends on many factors and conditions. Today I will talk about the most common problems and failures due to which bad reception or disappears altogether WiFi signal.

The WiFi signal suddenly disappeared

— the router shut down. Try rebooting it by turning off the power for a couple of minutes and turning it on again.

— If you have a laptop or tablet, check the battery charge. On many mobile devices To save energy, the Wi-Fi module can be forcibly disabled. Moreover, on laptops with Windows 8 and Windows 10, this option is often enabled in the adapter properties.

It is also worth checking the settings of the power supply circuit used.

— Approach the router at a distance of approximately 2 meters. No signal? Then you need to know for the test working device with wireless network interface— tablet, smartphone, phone, etc. If it works without problems, but your laptop cannot connect, then most likely there is a problem with the adapter driver. Try reinstalling or updating it.

It didn’t help and WiFi still turns off on the laptop? Take it to the service center.
By the way, on laptops and tablets there is often a case when, due to bad contact The antenna turns off during shaking. In this case, you need to open the case and solder it back.

If the test device also does not see the home network, then the problem is on the router’s side. Try resetting it to factory settings using the “Reset” button and setting it up again.

If it doesn’t help, take it in for repair.

Poor or unstable Wi-Fi signal level

The reason for the deterioration in wireless quality home network Most often, there are several more access points nearby. This is another one common reason Why does Wi-Fi turn off? Lately in apartment buildings this is just some kind of punishment. Almost every apartment has a router and in every entrance there are a dozen or two networks. In this case, there are two options: the right one and the cheap one.
—Correct option, but more expensive. Why? But because you will have to buy equipment operating at a frequency of 5 GHz, fortunately now it is already relatively inexpensive. Inexpensive dual band router will cost about 3 thousand rubles. For example, Totolink A2004NS router.

I think it’s clear that for a computer and laptop you will also need to buy additional adapters - that’s another couple of thousand. But with smartphones and tablets, things are worse - some already have support for the 5 GHz band, but simpler and cheaper ones will have to be left in the old range. But there will be no more problems with channel overlap and interference from neighbors.
— The cheap option is labor-intensive and hemorrhoid-intensive. Firstly, you will need to constantly scan the range with the inSSIDer program in search of a free channel, and then set it in the router settings.

Secondly, you will still have to drag most devices closer to the modem or router, since even if the selected channel is free, interference can come from busy neighboring ones. And there’s no getting around it. Just cover the house with 5 layers of foil.

I don't have networks in my neighborhood, but WiFi still turns off. Why?

In this case, the most common reason is the incorrect location of the access point in the apartment. To provide it with maximum coverage area, it must be located as close to the center of the home as possible. If you have points where Wi-Fi from the router still does not reach, then you need to set additional device- repeater.

The quality of the wireless network signal is greatly affected by:
- plasterboard (walls made of it or their finishing with plasterboard)
— reinforced concrete walls(reinforcement has a critical influence)
- water. Very often in houses or apartments they like to place a large, very large aquarium against the wall. After this, a pandemonium with the network may begin in the next room and the owner will be visited by the question “why is Wi-Fi turned off?!”
— electronic devices . If there are a lot of electronics (TVs, microwaves, radios) and the like in the space between the router and the computer (laptop, tablet, smartphone), then you will immediately notice a deterioration in the quality of work.

Don’t forget that the reason why WiFi turns off can be software or hardware. router malfunction.

In my memory, there is one case with the D-Link DIR-615 K2. The owner complained to me - “Wi-Fi is disappearing!” I checked the settings - everything is correct. But after some time the access point simply turns off. And through the LAN ports of the router everything works fine. The solution was a simple firmware update, after which the problem was successfully resolved.
Another case was with a device from QTech, where the contact fell off when dropped from the table internal antenna. The manufacturer regretted the solder. We opened it, soldered the antenna and WiFi does not disappear. Although, if you are not comfortable with a soldering iron, then if you suspect that Wi-Fi is disappearing due to a hardware malfunction, take the device to a service center.
