Why does wifi turn on spontaneously on my phone? WiFi turns off on a laptop - we solve the problem! Reasons for an unstable connection

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. The biggest problem is 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 the 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. You may encounter a similar problem 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 set periods of complete inactivity of the 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 the received wireless signal, which leads to regular connection interruptions. This usually happens automatically and unnoticed by the user.
  3. The Internet signal received by the router via cable or cellular network and converted into a wireless Wi-Fi signal is too weak. At such moments, you can observe that the laptop is still connected to Wi-Fi, but the Internet refuses to work. Also, a weak 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 this case, Wi-Fi on your laptop is automatically turned off until the router is turned on again, its software is restored, or until a forced reboot.
  2. Your laptop has an inappropriate or outdated wireless adapter driver installed. 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 Windows operating system that monitors how you use (or do not use) certain system elements and certain PC components. If any of them is idle for a long time, it is switched 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 the power plan that is currently installed on your system by default. 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 an ordinary radio wave, its power is influenced by a variety of factors, which may also affect the quality of the connection. The distance of the laptop from the router is not always the main reason for the decrease in 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 located between the Wi-Fi router and the 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 where signal reception is uncertain, where a message about searching for a network is displayed on the display of the router or mobile device, an external antenna can improve the quality of reception. To clarify information about network coverage of specific settlements, you should also contact your provider’s representatives.

Unstable operation of the router

If you observe unstable operation of the router, which leads to regular disconnection of the wireless connection, we recommend rebooting the device several times and closely monitoring its further operation. 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, not work very stable and require periodic updates.

A complete reset of the router can also help. 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 the installed driver is outdated or not the most suitable one. 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.

With the development of information technology, it has become difficult to imagine the life of a modern person without the Internet and, in particular, a wireless network, thanks to which he always stays in touch 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 look at all the possible reasons why the Wi-Fi connection on your phone turns off and will provide ways to solve them.

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. The address for entering the settings, as well as the necessary password and login, are usually indicated on the body of the router itself. By default, the local address of the router is “192.168.1.1”, the 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 automatically obtaining an IP address;
  • 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 the electrical network. Should always be on. The backlight color may vary depending on the router model.
  • The system indicator displays information about the correct operation of the device. Should blink constantly.
  • The WAN indicator shows Internet access via cable.
  • The WLAN indicator indicates that the Wi-Fi network is active.
  • LAN connection indicators show local connections to the router that do not affect Wi-Fi operation.

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 the 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 present, eliminate malware. It is worth understanding that anti-virus software is also external and can interfere with the normal operation of Wi-Fi.

It often happens that there are programs installed on your phone that block the Wi-Fi connection. One of these is a special program that allows you to save battery power. The principle of its operation is to automatically turn off unused modules, but sometimes there are failures and the Wi-Fi 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 the current settings or reinstall the software.

On phones whose manufacturers are more responsible for the quality of software and, as a result, for 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.

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:


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:


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 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

Hello! I have an iPhone 6s on iOS 10.3.2. After switching to standby mode, Wi-Fi turns off after 3-5 minutes and switches to mobile Internet mode. When you exit sleep mode, Wi-Fi turns on after 2-3 seconds. Tell me how to fix this situation?

In fact, Wi-Fi in standby mode does not turn off, but goes into a low-power standby mode. Disconnection from Wi-Fi may be caused by settings or features of the router. Some routers automatically disconnect consumers that do not request or forward packets over the network.

What can be done

1. First, check the operation of the iPhone in any other place with Wi-Fi (at work, at a neighbor’s). The main thing is that the router is different. Most likely there won't be a problem there. You can even turn off your mobile Internet during the check.

Wait for the phone to “fall asleep” and try sending messages to it via instant messengers for which notifications are configured in iOS ( Settings - Notifications).

2. The next step is to check the iPhone's connection to the router. We show you how to monitor connected devices to the network.

From a computer or other smartphone, see if the connection with the iPhone is lost after it goes into sleep mode.

3. If you find that your iPhone “falls off” from the network in standby mode, you need to tinker with the router settings.

  • Look for the setting first IP address lease time. Increase the value of the variable to several weeks or even a month.
  • Sometimes it helps to turn off the device EAP encryption. Try turning it off.

Wi-Fi is a technology that allows electronic devices to transmit data or connect to the Internet wirelessly. These days, the use of Wi-Fi is becoming very common and we can see this technology being used by a wide range of devices such as smartphones, tablets, gaming 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 helps prevent unauthorized access to the network. If you do not have sufficient knowledge to set up a 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 are facing the problem of Wi-Fi turning off on your Android device, try the following settings options and you will be able to connect your device wirelessly without much hassle.

Wi-Fi network overflow

The biggest interference to the Wi-Fi signal comes from neighboring wireless networks. The problem is that most Wi-Fi devices operate in the already occupied 2.4 GHz band, and the high density of 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 the desired channel number.

Most manufacturers resort to various methods to increase battery life. Android smartphone users are forced to enable such power saving features in their devices. One such feature is turning off Wi-Fi when the phone is inactive or when the device has low battery. Such features of Wi-Fi 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 Advanced — Wi-Fi in sleep mode do not select "Don't turn off".

On those devices running Android 4.0 ICS and higher, go to Settings - Wi-Fi, select Advanced and set the Wi-Fi during sleep option to "Always".

Change DNS servers

Changing DNS servers can solve the Wi-Fi problem when the Internet network on the phone disappears. Go to Settings - Wi-Fi and turn on Wi-Fi. If it's a known network, you'll have to "forget" it and then connect 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 your Wi-Fi password and connect to the network.

Reset to factory settings

If none of these methods work, 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 have 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 Wi-Fi connection. In addition, pay attention to specialized applications, since there are many applications in the Google Play store, 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.
