The wifi network disappears. Why is the connection interrupted? Wi-Fi is unstable. Why does the Internet cut out via a Wi-Fi router? What to do if the Internet via Wi-Fi stops working

On a laptop. Thus, the connection to the Internet is broken, important notifications and alerts do not arrive, but, as you know, it is impossible to live without the Internet. Many blame device manufacturers for this - laptop or router, although the problem is most often easily solved with a couple of mouse clicks.

Today we will study the main possible reasons for the occurrence of such a situation, and find out what to do if WiFi on a laptop stops working.

WiFi turns off on a laptop - we solve the problem!

If the laptop’s connection to the Internet via WiFi is unstable and constantly breaks down, then there may be several reasons for this - either certain operating system settings, a device malfunction, or poor communication from the provider or cellular network operator.

Perhaps you should also pay attention to this video to understand what factors affect the stability of the WiFi connection.

Disable battery saving

The main reason why WiFi constantly turns off on laptops lies in the power and energy saving settings. Since a laptop is a battery-powered mobile device, manufacturers are trying to reduce the power consumption of the device in favor of greater autonomy and longer battery life.

By default, device performance when running on battery power is slightly reduced in favor of energy saving. Also, to avoid wasting electricity on unused functions, the operating system turns off some computer components. For example, if the WiFi connection is idle or not actively used, the WiFi adapter can be disabled to save power. Therefore, your favorite laptop, left unattended, carefully disables unnecessary functions and deprives you of a stable connection to the Internet.

Power settings are located in the control panel. However, please note that the manufacturer often installs additional programs that allow you to control power consumption, and the reason for WiFi turning off may be hidden in them.

Open the taskbar and select Power Options. The control panel and the item we need can be easily found using the search.

In the power supply window that opens, you can see which power management scheme is currently active for you, and also proceed to its detailed settings.

In the window that opens, you can configure the screen timeout and sleep timeout. We are interested in the point that changes additional power options.

Find the item responsible for WiFi operation. Here it is long called a wireless network adapter. Change the value to high performance.

After changing the power plan, reboot your device and check if the problem is resolved.

Reboot the router

If the problem persists, rebooting the router may help. The easiest way is to turn off the power and turn on the device.

You can also reboot the device through the administration panel by going to 192.168.0.1 or 192.168.1.1 in your browser, entering your username and password, and clicking the appropriate button. The exact address and reboot method depend on the device model, and the login and password must be changed from standard admin/admin to your personal ones.

Checking the network signal and the stability of the Internet connection

We discussed how to increase the speed of a wi-fi router and the Internet in one of the previous articles. In our situation, it’s worth paying attention to how far the router is from the laptop and what obstacles the signal passes through.

If, in addition to WiFi, the Internet is unstable over a wired connection, it may be worth calling your provider and resolving the issue of poor Internet with them.

Internet speed can be easily checked using an online service speedtest.net- after all, if the values differ from those declared by the provider to a lesser extent, this is a reason to be puzzled by the quality and level of the signal.

Reinstalling the driver

Reinstalling the wireless adapter driver may also help. To do this you need to do the following:

go to the website of your laptop manufacturer;
enter the model of your device;
select the operating system;
download the latest version and install the new driver.

The method for downloading software varies depending on the device manufacturer and model. Try to download the latest versions of drivers for your operating system and device.

We have looked at the most popular reasons that lead to laptop WiFi constantly turning off. It’s good if the problem was solved by changing the power plan, and the performance of both the router and the laptop does not raise any questions. If the problem cannot be solved, it may be worth contacting a specialist.

You can also understand when there is no Internet at all. Most often, this signals problems with the provider if none of the devices can connect. But what to do if WiFi drops out at certain intervals. Here the problem can lie almost everywhere. Sometimes the device constantly disconnects, but after a few seconds the connection resumes again. In this case, you may notice loading interruptions or lags in the game.

In the operating system, in the lower right corner you can see a yellow triangle or even a cross. Or the connection speed may be slow. For example, pages barely load, although there is a connection. The signal level can be strong, and then fades and disappears again.

First of all, go to your router and reboot it. Just in case, before turning it on again, wait 2 minutes so that the device cools down a little; sometimes this happens when a large number of devices actively use the Internet. The receiving device must also be rebooted.

Reasons

Let's try to think about why Wi-Fi falls off:

The wireless network constantly disappears due to problems on the provider’s side - perhaps the lights were turned off during the day or night and the central switch to which your device is connected just hung;
Periodically falls off every few days. This may indicate the imminent end of the router.
An unstable or poor connection may be due to viruses or a broken driver. Or someone from the family turned on “Torrent” for a race - then everyone gets the channel.
The communication signal disappears - either the router is disconnected from the network due to light, a bad outlet, or the end device is very far from it. A reader once contacted me and complained about a similar problem. Later it turned out that it was all due to one load-bearing wall with steel beams, which jammed the signal.
The Internet breaks down only on one device: computer, laptop, phone, tablet. Perhaps the problem is in the built-in module or there is a power saving mode that turns off the network itself.

Communication channel

If the connection suffers only via the wireless standard, then most likely there are some shortcomings in the router settings. Modern routers operate on the 2.4 GHz standard; this standard has only 13 channels. Of these, only 11 are most often used. If you live in an apartment building and you have a lot of neighbors, then they can jam you.

For example, a couple of routers may be sitting on the same channel with you. If you actively use a wireless network, they will simply interfere with you. In general, when you reboot the router, the device itself should select the optimal channel. But if all the channels are clogged, he may not be able to do this on his own. Therefore, our task is to independently find a free channel - there are a number of programs for this. And then change it in the Internet center settings.

I have already written in detail about this. In addition, I would like to say that it is also worth setting the channel width to 20 Hz. The fact is that the channel width can affect interference; the narrower it is, the less interference from neighbors.

Reflashing the router

Updating the router's internal software often helps. On some devices, you can update the router directly through the Web configurator. For some, you need to download the firmware from the official website. There is no point in writing about each device, and on our portal we have separate articles for each model. To do this, enter the name of your router and the word “reflash” into the search bar. Then proceed according to the instructions.

Laptop setup

Very often this problem appears on the Windows 10 operating system. But perhaps it will help with versions 7 and 8.

Click on the “WiFi” connection;
Select the connection in the upper right corner, as in the picture above.
Go to network properties;
Check the box so that the laptop module constantly tries to connect to the network, even if it doesn’t see it.

Without leaving the cash register, in the same window in the second tab, turn on the “FIPS” mode.
And so we check our connection.

Wi-Fi disappears after waking up from sleep mode

In the Start menu, enter “Power Options” in the search bar and go to the section.

Next to the enabled mode, click on the link. If you have the “Energy Saving” mode turned on, I advise you to turn it off and switch it to “Balanced”.

Follow the first link above.

In the settings of the wireless network adapter, set the mode as in the picture above.

"Where Legs Grow From"

You need to understand which device is falling off. You can also do a test. Connect several devices to the router at once and see which device falls off. Very often Wi-Fi turns off on Apple phones. But often this happens due to incorrect settings or an old OS. On this subject we have.

If it turns off on all devices or the connection is very bad, then you should call your provider. I once had the same problem - I had the Internet, but it was impossible to access websites. In the process of solving the problem, it turned out that the switch that was in the attic was hanging. Therefore, we find the provider’s phone number and call him.

If everything is fine with the ISP, then the problem may be in the router. Try turning it off for about 10 minutes. If this does not help, then switch the power supply to another outlet - there may be a problem there. A friend of mine had a problem with a transistor inside the power supply. It burned out and kept shutting down.

Another very common problem is a low-power router. For example, if you bought a cheap router for 1200 rubles, there is a high probability that it will turn off under high load. For example, if the whole family tries to use the Internet in the evening. Some download, some watch movies, and some play.

If the router loses connection once a week, but recently the gap has become shorter, then most likely the device begins to fail. If it is old, then it’s time to think about purchasing a new Internet center.

Android phone problem

Go to “Settings” – “Network and Internet”;
Next, select our network and delete it;

If all else fails, try updating your operating system if there is an update. Resetting your Internet and Wi-Fi settings may also help. You can try resetting the application settings. If this does not help, if I were you, I would try to do a hard reset to the factory configuration. Perhaps the system broke down due to some programs or even viruses.

Wi-Fi not working on your laptop? Then you've come to the right place.

There are quite a few reasons when a laptop cannot connect to a Wi-Fi network. This article will provide an algorithm for solving this problem, taking into account the frequency of possible causes.

Step 1: Diagnose the source of the problem

If the connection to the wireless network is unsuccessful, the problem may not be in the client device (netbook, ultrabook, etc.), but in the router settings.

To do this, you need to try to connect to the wireless network using any other device equipped with a Wi-Fi module - another laptop, netbook, tablet, smartphone, etc.

If you were able to connect to the wireless network, the problem is with your computer. If the connection fails, the problem is in .

Step 2. Hardware enable the Wi-Fi module of the laptop

So, based on the diagnostics that we carried out in the previous step, it was determined that the connection problem occurred on one of the client devices of the wireless network.

As a rule, all laptops are equipped with light indicators for the operation of the wireless module and have a specific key combination to turn it on.

Pay attention! A glowing indicator indicates that the adapter is turned on. The absence of backlight indicates that the Wi-Fi adapter is turned off.

Most manufacturers place indicator lights on the front or one of the sides of the computer.

Less common is the location of indicators near the touchpad or on the monitor body.

On some HP models, a module status light may be built into the power button on the keyboard.

To turn on the Wi-Fi module, a key combination is used, which consists of a special Fn key and one of the system keys from F1 to F12.

Look carefully at the system (function) keys and find the Wi-Fi connection icon on one of them.

On some older models, in particular from the company, you can find a solution for turning on the Wi-Fi module in the form of a two-position switch.

Such a switch is usually located on one of the sides of the laptop or on its front side.

Below is a list of keys that can be used to enable/disable the Wi-Fi module on the most popular brands of laptops.

Acer: Fn+F3

Asus: Fn+F2

Dell: Fn+F2

Fujitsu: Fn+F5

Gigabyte: Fn + F2

HP: Fn+F12

After the adapter is turned on in hardware, connect to the wireless network. If the connection fails, move on to the next step.

Step 3. Software enable the laptop's Wi-Fi module

In addition to the hardware enablement of the wireless adapter, which we dealt with in the previous paragraph, there is also a software enablement, which is performed directly in the operating system installed on the laptop.

To enable the wireless connection adapter in Windows 7, you must complete the following steps: on the notification panel (near the clock), select the Internet connection status icon “Network and Sharing Center”.

In the left column, select “Change adapter settings.”

In the list of connections, you need to pay attention to the indication of the “Wireless network connection” item. If the adapter is disabled, it will not be highlighted.

To enable it, right-click on the icon and select enable.

The icon color should change.

Now you need to pay attention to the notification panel area. In the first case, the laptop's Wi-Fi adapter is turned on, but there is no network to connect to (usually this is a problem with the router).

In the second option, the adapter is turned on and you need to find your network in the list of connections and connect.

After software enabling the adapter, we try to connect to . If the connection fails, move on to the next step.

Step 4. Installing/reinstalling drivers for the Wi-Fi module

To check whether the driver is installed, you need to right-click on the “My Computer” shortcut, which can be found either in the “Start” menu or on the Desktop, select “Properties” in the context menu, and select the “Manager” menu in the left column of the window that opens devices".

In the window that opens, you need to find the “Network Adapters” menu and find the name of the wireless adapter, which contains part of the name “... Wireless Network Adapter” or “Wireless Network Adapter …”, where instead of “…” there should be the name of your wireless adapter, for example, Atheros , Realtek, Qualcomm.

In our case, this is Atheros Wireless Network Adapter. Right-click on it and select “Properties”. In the menu that opens, you need to make sure that “The device is working normally.”

Important! If you do not find the name in the “Network Adapters” menu, you need to install drivers. Drivers can be found on the disk that came with the laptop, or by searching the Internet.

Step 5. Fix connection problems in the router

In the first step of our article, we looked at how to determine with a high degree of probability the possible reason why it is impossible to establish a Wi-Fi connection.

Since there are quite a lot of routers, and even more firmware for them, in this paragraph we will give general recommendations for troubleshooting the problem.

1. Try to reduce the distance between and the router. Try to ensure that there is direct visibility between the devices and as little interference as possible (walls, partitions, ceilings, microwave ovens, radiotelephone bases, etc.).

What to do if Wi-Fi on a laptop does not work

Why doesn't Wi-Fi work on my laptop? You can find out by running system diagnostics. You will learn how to do this in the video presented.

Recently, wireless technologies have almost completely replaced wired ones from our daily lives. And now almost every home, institution, and office has a WiFi router that allows several computers or mobile devices to access the Internet at once.

WiFi technologies certainly have their advantages, but they also give rise to certain inconveniences. If you suddenly Internet disappeared with an active wireless connection, or to router access point If you can't connect at all, then you've come to the right place. In this article we will talk about the most likely causes of problems and give tips on how to resolve them.

Problem 1: WiFi is connected, but there is no Internet

Since access to the Internet is provided through a network cable connected to the router (router) by the Internet provider (WAN port), and only then “distributed” via a LAN or WiFi connection, the first thing you must do is: eliminate the problem on the provider side.

It's very easy to check this by looking at WAN indicator in the router. As a rule, this is a globe icon or the inscription “WAN”.

If WAN indicator is off, it means the cable is damaged or there is no connection with the provider. In this case you should contact the provider's technical support.

If indicator flashes, - there is a connection, but there is no Internet connection. This may be the result router failure. It will be required reboot. To do this simply turn it off with the button and turn it on after a minute. Wait until the router is completely configured (the gear icon stops blinking) and reconnect to WiFi on your computer. If the problem persists, contact your provider's technical support. As a rule, such problems are resolved by employees within 3 minutes.

Problem 2: The Internet periodically disappears

It happens that the Internet disappears and then appears again. There are several possible reasons.

1. Poor Internet connection. The best way to check the quality of your Internet connection is to use one of the tips from.

2. Router problems. Reboot it as described in the section above.

3. Poor WiFi signal. If the WiFi indicator on your computer or other device shows a weak signal, check how far the router is from the computer. The more walls there are in the way, the worse the signal. However, there may be another reason - poor contact with the antenna or its incorrect location. Make sure that the antenna is securely screwed to the router body and is not damaged.

4. Laptop WiFi adapter problems. A yellow exclamation mark may appear next to the WiFi icon in the system track. Try turning the adapter off and on. To do this, the laptop has a special function key - an antenna icon or an airplane (turns on airplane mode). Another method is performed from a Windows system: click on the WiFi icon in the system tray and in the side menu that opens (Windows 8), move the Wi-Fi mode parameter slider first to the position Off, then On. Next, reconnect to the access point. If it doesn't help, restart your computer.

Problem 3: Unable to connect to access point

A very common problem is when you cannot connect to a WiFi hotspot. There are several possible options here, so the procedure is as follows:

First of all, you need to make sure that your adapter is turned on and not in airplane mode. To do this in Windows 8, just click on the WiFi icon in the system tray and check the item in the sidebar that opens Airplane mode(should be Off.) And WiFi(should be On.). You can see the screenshot above.
Next, check if the adapter finds the desired access point. If it doesn’t find it, make sure your router is plugged in and working. Doesn't help? Let's move on to the next step.
Restart the adapter using the method described in paragraph 4 of the previous section. If it doesn't help, reboot your computer.
In case the adapter finds other WiFi networks, But does not see your access point, - there may be a problem with encryption. Try and configure WiFi security settings so that you do not need to enter a password - item “Wireless mode” -> Wireless protection -> Disable protection. That is, there should be no encryption on the network. After this, most likely, your access point will appear in the list of networks. If you really need a WiFi password, try changing the encryption type to WEP.
If the computer does not find any WiFi network and rebooting does not help, the reason may be a failure of the adapter itself.

Bottom line

We hope that this article included all possible options for WiFi problems and that one of our tips helped you. If we missed something or you have any clarification, please leave comments. And, of course, like the post and share it on social media. networks!)

Electronic gadgets: computers, laptops, smartphones and tablets are found in every home. To ensure that all devices receive unlimited access to the Internet, users install routers in their apartments. These devices provide wireless access to the network from a single exit point. But here people are faced with a situation where the Internet periodically disappears through the router. We'll tell you how to solve the problem yourself, without involving specialists.

wi fi can disappear on any device

Possible reasons

If the Internet speed fluctuates, check the router's access to the network. When access is stable, the indicators should glow a steady green light. When there is a problem on the line, the indicators flash. The network disappears due to interference or incorrect device settings. You can solve the situation by rebooting the router; there is a button on the back panel for this.

WATCH THE VIDEO

If the Wi-Fi connection is lost, the following messages are displayed on the monitor screen:

No internet access. The problem is caused by an incorrect connection or a problem with the line. In this case, the Internet via cable connection and remote access disappears.
Obtaining an IP address. due to incorrect network settings. Check the setting in Network Sharing Center.
Lost connection. If it is constant, adjust the power setting. In particular, disable disabling network adapters to save power.

If the signal is unstable and the speed leaves much to be desired, contact your provider’s technical support.

Important! The provider's responsibilities do not include setting up a home connection if this item is not specified in the connection agreement!

If there are no technical faults on the line, but the signal level is still low, perhaps the problem lies in the reception. If Wi-Fi on your phone is lost, move your gadget closer to the access point. The speed has increased, which means there is interference on the path between the device and the router. The way out would be to install an additional amplifying antenna. When the signal level does not depend on the distance between the device and the access point, you need to look for a free connection channel. This situation is typical for apartment buildings, where several routers operate at the same frequency. Let's look at how to solve this problem.

How to connect to a free frequency?

If Wi-Fi on the router has disappeared, then you need to install the InSSIDer program on your computer. The application will scan for available wireless networks and display free channels with a graphical image.

Please note that the utility costs money. The free version is only available for Android mobile devices.

Let's understand how the utility works.

From the same graph it is clear that the fourth channel is free. To troubleshoot connection problems, you need to connect the router to a different frequency.

Please note that it is recommended to select a channel that is farthest away from other frequencies in use. It is worth considering that the frequency width varies between 20-40 MHz, and the channels are located 5 MHz from one another. Accordingly, the selected frequency will invariably overlap with neighboring ones. Choosing the right channel will fix the problem when the laptop loses the Wi-Fi network. It is worth noting that router models have from 11 to 13 channels of available connection, so reconfiguring the device will not be difficult.

If the network on your phone disappears, the mobile application will help. This utility will not only determine the free frequency, but will also help check the quality of reception at various points in the apartment. The application displays a graphical representation of wireless networks, allowing you to select the optimal frequency. Thanks to this, you can correct the situation when Wi-Fi on your tablet or mobile device disappears.

Other options

You need to check the default settings of the router.

The installed parameters must match the recommended ones. If there are discrepancies, the device does not work correctly. Some routers may not be able to handle the flow of information.
In addition, budget models do not support dual-frequency operation. High speed and dual-stream connection overheat the router. The result is unstable operation and causeless connection breaks. In this case, the solution to the problem is to replace the router.

There are several options for getting out of the situation; using the tips provided, you can establish a stable wireless connection in your apartment.
