The wifi signal disappears. Why does the Internet disappear through the router? Low reception signal and presence of interference

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 on their laptop turns off. Below we will describe 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 the laptop, router and Windows. Hardware problems most often include a physical malfunction of the device. And this 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:

the connection with the router is interrupted due to a weak signal;
the network is turned off to save energy;
fault on the driver side;
interference from 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, you need to find a suitable module and replace it.

Energy Saving Settings

The quickest way to try to fix a Wi-Fi problem is to go into the power plans 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 Energy Saver mode, where many computer components operate at lower frequencies. If your laptop model turns off the Wi-Fi adapter itself when saving energy, then you can configure the parameter accordingly like this:

Open the Execute window using the “Win + R” keys.
Enter the command “control powercfg.cpl”.
A window with power settings will open. There we select the “High Performance” option. Or, in the already installed mode, click on the item “Setting up a power plan”.
In the window that opens, click on the item “Change additional power settings.”
Find the option “Wireless network adapter settings”.
In the next step, find the “Energy saving mode” section and change it to “Maximum performance”.
Save the settings.

Therefore, the wireless adapter should not be disconnected periodically. If this problem persists, move on to other fix options.

Low reception signal and presence of interference

When connecting to a router other than your own, you may notice a weak signal level, due to which Wi-Fi drops. This can be seen on the network icon and the number of sticks responsible for signal strength. Of course, even with poor reception, the connection can remain stable, but at some point, a break in the connection may occur 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 emitting waves of different frequencies make the connection to the Wi-Fi network unstable.

The easiest way to get rid of this problem is to place 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 your laptop using some task manager settings that need to be changed in the energy saving section; 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 Win+X combination and go to the device manager. You may have the Windows 7 operating system installed, then open the Run window using the “Win + R” combination and enter the following: devmgmt.msc.
Expand 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 and uncheck the “Allow the computer to turn off this device to save energy” option.

Steps to take when reinstalling 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 automatically. In addition, install the already downloaded driver.

Now, when the router loses the network, the software methods described above will fully help you get rid of the problems that have arisen. Now, regarding the router.

The problem is 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, at least you can restart it. The wireless network crashes for the reasons described below.

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

A known cause is power outages. 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 operate 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 router software (firmware);
temporary refusal to use torrent programs;
using a different router.

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

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

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

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

Wi-Fi router signal range

So, let's try to find out what is wrong with the 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 network that always disappears. Perhaps you are constantly losing connection to the Wi-Fi network due to the fact that your laptop is physically far away from the router’s coverage area. A Wi-Fi adapter may be able to latch on to a weak signal, but then it weakens so much that the connection can no longer be maintained. Also, do not forget that the propagation of the router signal can be affected by various obstacles in the form of walls, furniture and various household appliances.

Changing the Wi-Fi network distribution channel

Have you gone around and experimented with the signal range, but the wireless network still disappears on your laptop? Okay, then let's move on. Another reason why Wi-Fi on your laptop may disappear is interference or a busy wireless network distribution channel. By default, the settings of any Wi-Fi router should automatically select the channel for distributing the Wi-Fi network. However, perhaps this is the problem. You need to go into the control panel of your router and try setting a different channel for the wireless network.

To access the control panel of your router, you need to connect it to your computer via a network cable, and then enter the address specified on the Wi-Fi router or on its box into the address bar of your 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 Wi-Fi channel setting. 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 the settings and see if the Wi-Fi situation on your laptop has changed. If yes, then leave the channel settings in the router’s control panel and calmly use the connection on your laptop. If you have other devices, make sure that they also connect normally to the router's network. However, if your Wi-Fi adapter on your laptop still keeps disconnecting from the wireless network, then there is something else going on.

Disabling Power Saving Mode

Another reason why your laptop keeps disconnecting from the wireless network may be the power saving mode that is set in your power plan settings. Your laptop may be disconnecting from the network in power saving mode. So, right-click on Start and select “Power Options” from the context menu.

Once the power settings window for the system is open, click on the “Advanced power settings” link. In the next window that opens, you will be able to see which scheme your laptop is running on (you could select different power schemes through the battery icon in the notification panel). Select the power plan you need, and then click on the “Set up power plan” link.

In the window with options for turning off the display and sleep mode, click on the link “Change advanced power settings.” A small window will open with a list of power settings, among which you need to find “Wireless network adapter settings.” Open this option by clicking on the plus icon on the left side and set it to “Maximum performance”. Save the change to the laptop's power settings. All you have to do is uncheck one box in the Wi-Fi adapter settings.

Click on your keyboard Windows+R to open the Run utility. Next, enter the command in it 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 you have to do is uncheck the “Allow the computer to turn off this device to save power” option. Once everything is done, save the changes you made and restart your laptop. Now test your wireless network connection.

Reinstalling the 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. The last thing you have to do is test the theory with a bad driver for the adapter, but if after that nothing changes, 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. After downloading the driver, set it aside for later, as now we will remove 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 your router's 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 lot of glitches, for example, it can cause constant interruptions in access to the Internet or even disconnect from the wireless network .

We hope that reinstalling the driver was able to resolve your issue. However, if the laptop still keeps disconnecting from the wireless network, then as we suspected, there is definitely something 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

When starting a laptop with Windows 10 / Windows 7 or a buggy Windows 8, one day you may find that the wireless network icon - wifi - has disappeared. What to do then? How to fix it?

Wi-Fi (Wireless) is the most widely used wireless connection between a laptop and the Internet.

Wireless Wi-Fi connection is almost a monopoly in its industry and the versatility of this solution is beyond doubt.

It minimizes compatibility issues and this technology is rapidly developing.

Unfortunately, the more users use it, the more errors and malfunctions arise, one of them is that the icon is missing or has disappeared.

ATTENTION: the entry below is already a little outdated (written at least 5 years ago), so I recommend looking for a solution in a new one, written quite recently -

No wifi icon

To connect to a Wi-Fi wireless network, you must have an appropriate receiving device (for example, a network adapter) that is compatible with the sending device (for example, a router).

When you start your laptop, you should be able to view detected networks by clicking the wireless network icon. It happens that the icon is not displayed - it has disappeared. Why?

If you're using a mobile device, you'll first need to find out if it's in Airplane mode, which disables the ability to communicate.

If after starting the device in standard mode the wireless network icon is still not displayed, check whether the network card is running.

In laptops, it is launched using a special switch (on the case) and through a combination of function keys.

To do this, launch Device Manager (Control Panel → Hardware and Sound → Device Manager), select Network Adapters, open Properties, and launch the appropriate settings.

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, the Wi-Fi module can be forcibly disabled to save energy. 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 for the test you need a known working device with a wireless network interface - a 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 poor 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 the quality of a wireless home network is most often the presence of several more access points in the neighborhood. This is another common reason why Wi-Fi turns off. Lately in apartment buildings this has been 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. An 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 install an additional device - a 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 when it fell from a table, the contact of the internal antenna fell off. 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.
