I started experimenting when WI-FI on modern smartphones periodically disappeared. On both. The modem needed to be rebooted. Started changing channels WI-FI settings. Did not help. I thought it was the modem's fault. I bought another one for the experiment, the same one, used. Did not help. I started changing the settings again. Changed the standard b/g auto to only b, only g. I changed the transfer speed from automatic to maximum (54 Mbit/s). I even changed the transmitter power. Unsuccessfully.

Using the Insider 1.2.8.0331 program (suitable for my XP on a laptop with a WI-FI adapter), I found out that somewhere close neighbors have very powerful WI-FI, the signal of which is only slightly weaker than that of my weak old “unicorn” Pirelli. The 5GHz band is completely free, but my Pirelli only works in the 2.4 GHz band. :(((Moreover, the neighbor’s router is turned on in automatic channel selection mode. I saw how it suddenly changed channel from 11 to the first. So maneuver by “running away” to free channel I don't have a chance.

I tried to overcome the “one-hornedness” by purchasing a new “two-horned” router TL-WR841N, connecting its “WAN” input to the output of one of Pirelli’s “LANs”. Based on the laptop, I estimated that the “two-horned” signal was a little stronger. HIS WI-FI did not disappear even when neighbor's WI-FI“ran into” his channel. I seemed to have solved the problem, I thought about turning off Pirelli’s WI-FI and using two routers. Then I tried to experiment with old Pirelli (something better affordable price I can’t find it for DSL). I remembered that if you just remove the Bluetooth speaker from the smartphone, when the sound starts to stutter, the radio transmission most often stops, and the smartphone pauses. This is because the smartphone not only transmits a signal via Bluetooth, but also “communicates” with the speaker. The connection is disrupted - the smartphone goes into a stupor.

I thought that using WI-FI I could try to facilitate communication between the router and smartphones and laptops. After all, it not only transmits a signal, but also encrypts it using WPA. I decided to temporarily disable encryption. And, lo and behold, the WI-FI stopped interrupting altogether!!! Then I turned on the simple ancient WEP encryption- Also full order! Insider 1.2.8.0331 showed that all competing networks use WPA, WPA-2, WPA-T, etc. encryption. Now I only have WEP. The moral of this story is this. If I'm set to WEP, my router doesn't even try to read the neighbor's WPA-encrypted signal. There is interference, it produces noise, but my native signal level on smartphones and laptops is sufficient. Changing the encryption helped the router add selectivity and tune out powerful interference. Even when the powerful neighbor’s WI-FI “sits” on my channel and simply “breathes down my back.” That's how I understood it. Maybe it will be useful to someone. Specifically, weak encryption is not a problem for me. The signal of the “one-horned” Pirelli sharply weakens as we move away from our apartment. And if someone pushes himself and connects to my network, he will have DSL speed, and the desire to interfere will immediately disappear. :)))

Interesting experience, Thank you!
But I still wouldn’t recommend setting the type WEP security. The problem is not only that it is not safe. There may be problems connecting new devices to Wi-Fi networks.

I have MODERN smartphones Xiaomi Redmi 6 32/16 GB (Android 8), or, instead of one of them, Windofon ( Windows mobile 8.1/10) Nokia Lumia 535.0 (2014). To be fair, the TL-WR841N router, which initially works with WPA encryption, has two WI-FI: encrypted and open, for a maximum of 32 guests. I immediately turned it off there open WI-FI, so that with my DSL I don’t lose the Internet, losing its speed (512-1024 KB/s) to the speed of the oldest switching modem (56KB/s) connected to telephone line, popularly called “donkey”. I remember my donkey, I even kept two living specimens. :))) In short, the TL-WR841N router has the opportunity to test the refusal of encryption as a way to overcome powerful interference.

I only left one with my Pirelli non-standard setting: instead of “b/g mixed” - “g only”. But this is not important at all, and does not save you from interference.

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 via voice communication, when suddenly access to the Internet is turned off, 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 wifi shutdown, 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 idle time, makes a break wireless connection Because of this, 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 the laptop's wireless adapter is not able to pick it up, resulting in the connection being disconnected. This is why it is so important to purchase devices with a powerful transmitter.

Often, the Internet signal transmitted via cable and converted into a wireless connection in the router is 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 work wifi 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 not suitable driver adapter wireless wifi connecting a laptop also leads to periodic disruption uninterrupted operation, or even the computer does not detect available wireless connections.

The problems described above are the most commonplace, but other reasons also occur and it is necessary to remember that every specific case is unique in some way 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 batteries, they usually come with special programs or use standard means operating system to make energy saving effective. 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 link “Edit Extra options nutrition." In the window that opens, open the adapter settings wireless connection, find the “Power Saving Mode” icon and there, change the values ​​to maximum mode performance, in other words, prevent the program from disabling the wireless adapter. Now the operating system will not be able to interfere with the wireless connection and interrupt its operation.

Weak access point signal

For quality wifi signal The router 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 it comes to 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

With obvious wifi problems A series of reboots can help the router. 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 the wireless connection can be interrupted and you can find a solution to this problem.

With development information technologies it has become difficult to imagine life modern man without the Internet and, in particular, a wireless network, thanks to which he always stays connected and has the ability to quickly resolve all sorts of issues. This is why a sudden connection loss makes the user nervous and stressed in fear of missing something important. This article will cover all possible reasons why does it turn off? WiFi connection on the phone and ways to solve them are given.

Causes of problems

In most cases, problems with connecting to a wireless network can be caused by the following reasons:

• errors in Wi-Fi network settings;
• router malfunction;
• third-party programs downloaded to the phone;
• low quality software.

To solve the problem, it is necessary to correctly diagnose the source of its occurrence. In many cases, this can be done independently, without the help of specialists. You can troubleshoot problems using the recommendations below, which are given for any phone operating system. Sometimes the Internet may work slowly and poorly due to network congestion, as too many devices are connected.

Errors in router settings

The first step is to check for errors in the router settings. To do this, you need to log into the control panel by opening it through a browser. Address to enter settings, as well as required password and login are usually indicated on the body of the router itself. Standard, local address router: “192.168.1.1”, username and password are the same: “admin”.

After gaining access to the settings parameters, you need to check them:

• the inclusion of a DHCP server, which is responsible for automatic receipt IP addresses;
• channel width (shaping) is set automatically, can be from 5 to 40 MHz;
• channel selection is also performed automatically;
• the data transfer rate should be set to the maximum of the presented values;
• The choice of region is rarely the source of the problem, so it is better not to change it;
• Security Settings.

You can download the file with the software on the official website of the device manufacturer. To reflash the router, you need to go to the “System Tools” section and to the “Firmware Update” category. After that, you will need to specify the path to the firmware file and update it.

Router malfunction

If the router settings did not help determine why Wi-Fi stopped working, you need to check the device itself for problems.

The correct operation of the router is shown by light indicators:

• The power indicator indicates that the router is connected to electrical network. Should always be on. The backlight color may vary depending on the router model.
• The system indicator displays information about correct operation devices. Should blink constantly.
• The WAN indicator shows Internet access via cable.
• The WLAN indicator indicates that the Wi-Fi network is active.
• Indicators LAN connections shows local connection to the router, which do not affect the operation of Wi-Fi.

Router operation

If the WLAN indicator is not lit or blinking, you should check whether the wireless network distribution is disabled: many routers have a button to limit the methods used to connect to the Internet.

The problem may also be directly in the connection of the router to the Internet - the WAN indicator does not light up. These may be problems on the provider's side, which can be easily checked by connecting network cable to the computer. If the indicator does not light up even when the cable is connected, then most likely the WAN port of the router or the cable itself is broken, and you should contact a specialist.

In situations where the Internet connection is poor, you can reboot the router using the power button or disconnect from the network. A technical breakdown of the device is also possible, in which case you need to contact a repair service or buy a new one.

Availability of third party programs

Another reason why the wireless network on the phone disappears is that the device is infected with viruses. To eliminate it, you need to install an antivirus and, if available, eliminate it. malware. It is worth understanding that antivirus software are also external and can interfere normal operation Wi-Fi.

It often happens that there are programs installed on your phone that block the Wi-Fi connection. One of these is special program, allowing you to save battery power. The principle of its operation is to automatically turn off unused modules, but sometimes there are failures and wifi adapter turns off even when using the Internet. This problem may be indicated by the fact that Wi-Fi on the phone constantly crashes. To solve it, you need to disable or uninstall the mentioned program.

Low quality software

Some users are faced with the fact that their phone stops seeing possible Wi-Fi networks for connecting. The problem may be due to unlicensed software installed or a change in factory settings. In such a situation, you need to reset current settings or reinstall the software.

On phones whose manufacturers are more responsible for quality software and, as a result, to the brand image, this rarely happens. That is why you should pay special attention to choosing the brand of smartphone.

Problems with your phone and the networks connected to it can often be resolved on your own. However, you should not try to figure out internal problems without experience, since physical intervention can lead to damage to the device. If the information presented in this article does not help, you should contact specialists at diagnostic centers.

We regularly use Wi-Fi connections, at work and on vacation; this technology wireless communication has become such a part of our everyday life that it is difficult to imagine life without it. A common error is when Wi-Fi turns off spontaneously on Android devices, can disrupt the execution of urgent tasks, which means this problem must be solved or prevented.

Reasons for an unstable connection

The first step is to determine why the network is unstable. There are many reasons why Wi-Fi connection on Android is unstable. Here the most common of them:

• Firewall mobile antivirus blocks the connection.
• Software malfunction.
• Incorrect router settings.

It is worth noting that the last two points are related to the Android operating system only indirectly: that is, the reason unstable connection lies not in the smartphone or tablet, but in the router and its settings.

So, let's take a closer look at these errors and their solutions.

What programs affect the connection?

Most often, the error when Wi-Fi turns off on Android is associated with the use of mobile antivirus programs. The fact is that the Firewall of such applications simply blocks the network in order to increase security.

Similar problems can be created by other applications that are somehow related to the work wireless module. Eg, Virtual router or Portable WiFi Router. Such programs can make certain changes to the parameters of the wireless module, resulting in failures. The solution is to remove such programs. If this does not help, then you should perform a factory reset.

Software failure

Sometimes the problem with connecting to a wireless network occurs due to a software glitch. For the most part, Android loses Wi-Fi connectivity after a software update, but quite often and just out of nowhere. In this case, the first thing you should try is a general data reset. Enter your device settings. In the “Accounts” tab, find the “Backup and reset” item.

On older ones Android versions Data reset is located in the “Confidentiality” section.

It is worth remembering that after performing the reset, all data contained on the device’s internal memory will be deleted. Therefore, it is recommended to first save them to your computer.

If the problem does not disappear, then there is only one option left - flashing the device firmware. If your smartphone or tablet is still under warranty, then it is better to contact a service center, since independent firmware you lose your warranty. If the warranty period has expired, then you can try to flash the device yourself: it is quite simple, and there is a lot of information on the Internet on how to do this.

It happens that you seem to have configured it correctly Wi-Fi, and he sometimes disconnects on its own. On outdated laptop models, there was a mechanical lever on the side to turn on the Wi-Fi network, which users accidentally turned off and the Internet and the network disappeared. Most users did not even realize that this lever existed. Today, on modern laptops, these levers have been removed and the controls have been transferred to the keyboard, but no one dares to write instructions for laptops, relying on the user’s intuition. The average person, even when he is advanced, generally suffers for a long time trying to find a simple solution, only because there are no instructions for the keyboard control keys. A person believes that if he gets a new laptop with the OS already installed, then it will be configured and all functions will be enabled. Thus, we need to list the most common reasons why the connection seems to be established, but keeps getting interrupted.

1. The signal source (router) is very far away and the signal is very weak. Install an antenna that will amplify the signal or make one yourself. Pay attention to the indicator in the lower right corner of the monitor, which looks like a ladder; it displays the signal level of the router.

2. Located near your network powerful source interference Install an amplifying antenna or make one yourself.

3. On your old laptop, find the lever with the network icon and switch it to the “On” position.
On modern laptops this can be done using the keyboard. Find the “Fn” key (usually in the bottom rows). Press and hold it, press the key with the Wi-Fi icon (looks like an antenna with diverging waves). Along with this, the power indicator with the same icon on the laptop body should light up.

4. The most common reason for modern laptops The communication services of pre-installed operating systems are disabled by default. To check and activate services, you need to go to the “Start” menu - “Control Panel”, select “Programs and Features”. In the “Programs and Features” tab, click on “Turn Windows features on or off.”
In the window that pops up, point the arrow at each item that is not checked in turn, and read the hints about what they refer to. Check the boxes next to all items that relate to the network, Internet, TCP protocol. Click OK. Wait for everything to install and reboot.

If you have installed licensed Windows and it is not contaminated with viruses and experimental software, your connection interruptions will stop. In other situations, calling a specialist is required.

Hello. Laptop owners very often contact me with questions regarding problems with connecting to the Internet. In the article, I have collected effective methods that will help fix problems with wifi on a laptop running Windows 10. Most often, the signal disappears or the wireless network adapter turns off spontaneously. Now let's look at these defects in more detail.

The laptop finds desired point access, connection is made, the Internet is working. But not for long... After a while it is displayed in the tray Exclamation point on the network connection icon. This indicates the limitations that have arisen. I have to connect again, but soon the problem makes itself felt.

Also, there are times when a red cross appears on the network status icon, indicating an unidentified connection error. Most often, such troubles appear after a system update or. But first you should check whether other devices (smartphones, tablets) can connect to the access point in order to exclude a malfunction of the router.

And sometimes the laptop simply does not see wireless networks. Or they either appear in the list of available points or disappear. I am sure that many of you have encountered similar problems.

Proven solutions

Now we will look at several ways to eliminate them. I recommend using them in the order in which I will describe them.

Deleting a Wi-fi profile

There is a possibility that some changes have been made to the router settings, and the laptop is trying to use an “outdated” profile to connect. To delete it and trigger the creation of a new (updated) one, use the command:

netsh wlan delete profile name=

As practice shows, it is not the connection process or even the setup process that causes the greatest problems for users when working with Wi-Fi and routers. Most big problem There comes a time when, after setting up, the Internet regularly disappears, a message about an interrupted connection constantly pops up, or you simply cannot open a single site on your laptop. In this material we will try to find out what causes such problems and what to do if Wi-Fi on a laptop turns off.

Reasons for automatic network shutdown are quite common.

What could be more annoying than experiencing a connection dropout while working on a laptop? Just now everything was fine, and you were calmly watching a movie online, and now the playback has stopped, the movie has paused, and the Internet has completely disappeared. WITH similar problem you may encounter for a variety of reasons. The most common are the following:

1. Your laptop has battery saving mode enabled. This leads to the fact that after specified periods of time complete downtime device, the wireless connection is interrupted automatically, the Wi-Fi adapter stops exchanging packets with the router and thereby saves battery power.
2. 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 intake wireless signal, which leads to regular connection breaks. This usually happens automatically and unnoticed by the user.
3. The Internet signal received by the router via cable or cellular network and convertible to wireless wifi signal, 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 signal transmitted through the cable may cause the wireless connection between the router and laptop to turn off automatically.

1. The router through which you access the Internet is unstable, constantly freezes, and reboots spontaneously. In such Wi-Fi case in your laptop is automatically disabled until the router is turned on again, its software is restored, or until a forced reboot.
2. Your laptop has the wrong or outdated driver adapter wireless networks. As a result, 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 whether the power saving mode is activated on your computer. This is a built-in feature of the operating room Windows systems, which monitors how you use (or don't use) certain elements systems and certain PC components. If any of them is idle without work long time, it is turned off automatically by the system. Windows does this in order to save battery power, which is sometimes the only power source 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 Configure power plan, which is set by default on your system to this moment. Everything you need can be found at 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 help you get rid of the situation when the Internet is turned off at the request of the operating system.

Weak router signal

Typically, a weak signal coming from a Wi-Fi router can cause the network connection to drop out regularly. Since the router signal is the most common radio wave, its power is affected by the most various factors, which may result in poor connection quality. The distance between the laptop and the router is not always main reason reducing signal strength. These may also 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 thinking about revising the location of the router or expanding the network radius using 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 displays an error indicating that the connection has been lost.

Metal objects between Wi-Fi router and laptop, also significantly reduce the stability of the connection in the wireless network through which you access the Internet. Take this into account when organizing your home local network.

Weak network signal

If the signal from your internet provider via cable or cellular network is too weak, the router may become unstable, turning off the access point and interrupting the 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 with uncertain signal reception, where on the router display or mobile device A message about searching for a network is displayed; an external antenna can improve the reception quality. To clarify information about network coverage of specific settlements you should also contact your provider's representatives.

Unstable operation of the router

If you are watching unstable work router, which leads to regular disconnection of the wireless connection, we recommend rebooting the device several times and closely monitoring it further work. Or go to its control panel, check for software updates and install them if necessary. Since the router runs a special operating system, it, like any other, can accumulate system errors, do not work very stable and require periodic updates.

May also help full reset router settings. We recommend doing this only if you know the settings for your provider and can reconfigure it yourself after resetting. Otherwise, contact the provider through the official website or by calling the hotline.

Driver failure

If your laptop’s wireless network adapter driver has not been updated for a long time, or you began to experience problems with Wi-Fi disconnecting after the last reinstallation of the operating system, it may well be that an outdated or not the most suitable driver was installed. We recommend that you find out the manufacturer of the network adapter installed in your laptop and download the latest driver. We definitely recommend doing this on the manufacturer’s official website.

Conclusion

Whatever the reason for your laptop's Wi-Fi turning off, one of the troubleshooting instructions below may help you get your network back to normal. If you tried all the instructions from this article, but none of them helped to identify the cause and get rid of the problem, you should contact a service center to test your router and network adapter in your laptop, since the problem, apparently, lies somewhat deeper.
