Wifi cuts out. Wifi not working on laptop. How to reconnect. Unstable operation of the router

Modern life is hard to imagine without access to the Internet. And it is especially unpleasant when the Network turns off by itself at the wrong moment. Such problems often occur with wireless connections on mobile devices. What could be the reasons for such failures, why WiFi suddenly disappears on the phone, and how to solve such a problem? The article below describes the main situations when WiFi is turned off on a smartphone and recommendations for troubleshooting.

The main reason why WiFi is turned off on the phone is incorrect router settings. The router itself may be fully functional, but it will not work effectively due to poor location or incorrect configuration.

Also, the quality of communication is affected by a large number of other access points that are within the range of the router. As a rule, in such cases, the Internet periodically reconnects on all wireless devices (tablets, mobile phones, smart TVs, laptops), which causes a lot of inconvenience.

Important: WiFi connection stability can be affected by household appliances operating on the same frequency as the router (microwave ovens, cordless phones). When you are near them, the WiFi connection may also be interrupted.

To solve the problem, first of all, you need to disconnect the router from the power supply, then connect it again. This will help if errors have accumulated in the router software, due to which the Wi-Fi began to “fall off”. Further, if WiFi is unstable, you can proceed to setting up the router. Then you need to go to its web interface. This can be done on a device connected to its Network:

Note: for iOS phones, you need to configure the router so that in the 2.4 GHz band it works on channels 1 to 11. When the router is running on the 12th and 13th channels, the iPhone will not see such a Wi-Fi network. This is not the case with Android smartphones.

It is also possible that as a result of a failure on the router, a reset occurred. If the Network name and password were different from the factory ones, WiFi access on the phone could disappear by itself, and the device would write messages like “ ”. Then you will have to reconnect to the Network, as well as restore all the settings of the router (specify the type of encryption, enable the DHCP server, specify a different wireless network password). All this is also available in the quick setting mode.

Important: sometimes the provider can block access to the web interface of the router at the firmware level, so you won’t be able to enter the settings in the usual way. In this case, you should contact technical support.

If all the data is set correctly, but the Wi-Fi on the phone is unstable, you need to proceed to the next diagnostic steps.

Router malfunction

Perhaps the router has a software or hardware malfunction that does not allow it to work stably. If the previous recommendations did not improve the smartphone's WiFi connection, you can reflash the router. This is done in exactly the same way - through the web interface, but then you will need to go to the system settings related to the software update. You can download the firmware file from the official website of the router manufacturer (the company name is indicated on the top of the device case and on the factory sticker at the bottom). Instructions for different types of routers are different, so you need to clarify the procedure for your device. After flashing, you will need to restore the Network settings (can be done through the "Quick Setup").

The software update did not help, is the distribution of Wi-Fi still unstable? Perhaps the problem lies within the device itself. An obvious malfunction of the router can be determined by the fact that some mandatory indicators are not lit or are lit in red. The power indicator, Wi-Fi and WAN indicators must be lit.

Important: when buying a new router, it is advisable to immediately check its serviceability, since a hardware problem can be identified already at this stage.

Note: after a long time of operation, most routers begin to freeze, spontaneously lose their Wi-Fi connection, home devices begin to “fly out” of the Network. In this case, it is recommended to install a new router and compare the operation of both devices. If the phone does not disconnect from WiFi on its own with the new device, it is most likely time to replace the router.

The presence of third-party programs that interfere with the connection

Suppose there are no problems with the router. Then why does the Wi-Fi on the phone turn off by itself? If the same Wi-Fi works well on another phone, viruses may be the cause of connection problems. If you suspect that your phone is infected with malware, you should download a mobile antivirus and scan the device. As a result of automatic scanning, all viruses will be neutralized. However, anti-virus programs themselves can interfere with the use of the Internet via WiFi, so it is advisable to check in the settings whether the anti-virus does not prohibit connecting to certain types of networks or certain sites.

Bad software on the phone

Most users of iOS and Android devices download applications from the official store. However, some programs are expensive, and some applications do not allow publishing the store itself, and therefore many programs can be downloaded from unofficial sources.

By installing a hacked application on your device, the user risks the safety of his device, since no one controls the security of such software. It is likely that after installing an unlicensed version of the game, the smartphone will start to work incorrectly, including the loss of WiFi connection on it. This problem is solved by removing unlicensed programs and completely resetting the smartphone to factory settings.
Similar problems can also arise when unofficial firmware is installed on the phone, which are presented in abundance on thematic resources by enthusiasts. As a rule, they do not have enough “strength” to release a quality software product, and therefore some service applications may not work properly under the control of such software. When asking the question why on the phone, it is always necessary to check the device for low-quality programs.

Incorrect phone settings

It is possible that the problem with turning on WiFi is caused by incorrect smartphone settings. First of all, it is recommended to check the power saving settings: most modern devices go into power saving mode when a certain percentage of battery charge is reached. In this mode, performance is sharply reduced, including the operation of the wireless communication module, for example, it may turn off after a while when not in use.

On Android smartphones (from version 4.0), you can disable this option as follows: open the Settings menu, go to WiFi, select Advanced > WiFi in sleep mode. Three options will be displayed in the menu: “Do not turn off”, “Only when powered from the network”, “Always turn off (more mobile data)”. To less often, you must select the first item. Then click "Save".

Conclusion

Most of the problems with WiFi on the phone can be solved on your own, the main thing is to correctly determine the cause of the constant shutdowns. But if the above methods did not solve the question of why the access point on the phone is turned off, you may need to reflash the device. Detailed algorithms and current firmware versions can be found on specialized resources.

However, when installing third-party software, there is a risk of losing the warranty on the device and its final damage, so that it will no longer turn on at all. If the problem is of a hardware nature, it is better to seek help from the service center specialists who will tell you if the radio module needs to be replaced.

The network is a very tricky "object": if it exists, then it is immediately gone! Today we will look at another common problem of spontaneous Wi-Fi signal disconnection on laptops. So!

You have a network: computer - Internet - laptop, but the signal on the laptop constantly disappears. Familiar?

What could be the problem?

There are several reasons why this problem occurs. Here they are: 1) violations when connecting to the DNS server; 2) old drivers on network adapters - sources of failure; 3) problems with the module (rarely, but it happens); 4) the router itself broke down (rarely, but it also happens).

All these reasons are not very common, but they have a place to be. But there is another reason that rarely anyone pays attention to, but, nevertheless, it is she who is the most common.

What are you doing to keep your laptop battery charged for as long as possible? Well, well, think. That's right: you put it into power-saving mode. By the way, very often this mode is configured in laptops by default. Yes, this is very true, because the battery holds a charge longer. But this is where the reason for the constant Wi-Fi break lies, friends!

Way to solve the problem

Here is a simple, understandable and accessible algorithm for solving the problem.

Regardless of what operating system you have, the essence is as follows.

"Start" - "Control Panel" - "System and Security" - "Power Options". Now you see: you have a "tick" in the item "Energy saving". Right there you have an active system link "Configuring the power plan" - click on this link. On the next page you will see another link "Change advanced power settings" click. You will get a Power Options window where you will see a menu. In this menu, find the item "Wireless Network Adapter Settings" and open it (click on it). The sub-item "On battery" will open and right there (opposite) you will see options for setting energy saving. So: the option "On battery: maximum power saving" will be enabled there. It is because of him that your Wi-Fi disappears. The solution is simple: select the option "On battery: maximum performance." Click "Apply" and "OK". Everything.

There is another option to fix the problem with Wi-Fi. Open the System and Security folder. In the "System" item, select the line "Device Manager" - "Network Adapters". At this point, find the adapter that is responsible for Wi-Fi (for example, Qualcomm Atheros AR9485WB-EG Wireless Network Adapter, in general, there should be the word Wireless). Double-click on this adapter with the left mouse button. A window will open with the properties of your adapter. Open the "Power Management" tab and uncheck the "Allow the computer to turn off this device to save power" checkbox. Click on "OK". Everything.

Good luck dancing with a tambourine, friends, and see you soon!

Wi-Fi disappeared on the laptop and a red cross is everywhere - this is the most common mistake. Although any user of modern devices has ever experienced problems with wi-fi connecting to the Internet. Unstable Internet (or even its complete absence) is usually very annoying, you want the problem to be solved as soon as possible, but it cannot be solved on its own - you need to diagnose the problem and make efforts to solve it. Just today we will look at the most common problems of wi-fi connections to the Internet and how to solve them.

Why wifi disappears - reasons

There are incredibly many reasons that could potentially cause the absence of a stable wifi connection (or connection in general), this is a banal removal to an excessively long distance, and the presence of any radio interference in the access point coverage area, and the presence of all kinds of shielding elements between the router and you. However, most often the network disappears due to software errors and hardware malfunctions.

Problem Diagnosis

If the Internet is lost via wifi, and there are no obvious signs of a hardware malfunction (a broken router antenna, for example), and approaching the access point to a distance of 3-5 meters did not help, you should start looking for software errors. The mechanism for their detection is individual for each specific OS and gadget. And yet, in the case of the most popular devices, such as Windows laptops, smartphones running Android and Iphone, there are some universal recommendations that, with almost one hundred percent probability, will help to detect the software cause of the lack of a signal.

If your gadget is running less popular operating systems, such as symbian, windows mobile, or even some kind of "self-written Chinese OS", it is not advisable to carry out software diagnostics, since there are usually no built-in mechanisms for this in such operating systems, and flashing will take much less time than "picking" in the program kernel.

What to do if wifi is missing on a Windows laptop

The reasons for losing a wifi signal on a laptop can be conditionally divided into three categories:

If, when you press the corresponding key on the laptop, the indicator of the wifi module (the light next to which wifi is written or the corresponding icon is drawn) does not light up, then the problem is in the device itself. Check if the corresponding option is enabled in the BIOS. To do this, restart the laptop and press the corresponding key in the first 3-5 seconds of loading. As a rule, this is F2, F8 or F12. However, the BIOS boot initiation key may be different - carefully read the notification that appears when you turn it on (usually the button you need is written at the bottom right). It is worth noting that your BIOS version may not have the option to enable the wifi module, so it is recommended that you first read the user documentation or enter a combination of: ““name of your laptop” wifi bios” into the search engine.

Lost wifi in windows

If the indicators of the wifi module and router are on, but there is no signal, you should check if wifi is enabled in Windows itself. Right-click the appropriate taskbar icon (the bar at the bottom or top of the screen), then click: “network and sharing center” => “change adapter settings” => find the icon for monitors with a wifi signal strength scale => “enable”.
Also, instead of right-clicking on the icon on the taskbar, you can click "start" => "control panel".

Often the reason that wifi disappeared on a laptop is faulty drivers. Right-click on the "computer" shortcut, select "properties" => "device manager" and find "network adapters". Make sure the adapter is turned on. If there is a yellow triangle next to it, select “update drivers”.

The reason for the unstable work of wifi may be the high load of the router. Check and disable the most active users!

If the laptop sees other networks, but cannot connect to the one that interests you, the problem is in the router settings. To diagnose it, you need to connect to the router using a cable or other device and type the debug address in the address bar of the browser: "192.168.0.0". In the window that appears, enter: "admin / admin". Next, you should check if wifi signal transmission is enabled, and if your device is on the “black list” of the MAC filter. You should also make sure that the router allows the simultaneous connection of several devices.

If the connection to the router fails even through the cable, you should hold down the "reset" button on the router and wait 10-15 seconds.

If none of the above helps, try calling your ISP and ask if it's getting feedback from your router (when it's up and running). If not, then most likely your router hardware has failed.

Wifi is constantly or periodically turning off on a laptop, what to do?

If the signal on the laptop appears and then disappears, and no matter what access point you are connected to, most likely the problem is in the system power plan settings. To fix this problem, select the "maximum performance" mode, however, be aware that this will affect battery life. Also, disable automatic hibernation - very often, after waking up from sleep mode, the wifi adapter de facto remains turned off until the next reboot.

Wifi disappears on iphone, what to do?

First, make sure that the problem is in the iphone, and not in the router - often, users mistakenly believe that wifi does not work on the iphone, although the reason is in the access point. If your gadget sees other networks, the iphone is working. Second, make sure you have the latest version of iOS.
If updating iOS did not help, click: "Settings" => "General" => "Reset" => "Reset Network Settings".
If that doesn't help, the iphone is faulty.

If the gadget does not connect to any network at all, either flashing it or going to the master will help. If it connects to some networks, but not to others, you should enable the bgn broadcast mode on the desired access point and try to set a static signal broadcast channel instead of the Auto mode. This can be done through the router settings menu (the above address is 192.168.0.0). It is also worth noting that not all android devices support pairing with wifi relayed through a laptop in forwarding mode (when the laptop acts as a router).

Lost internet via wifi, but there is a wifi network

If the device is connected to an access point, but there is no Internet, check the cord going to the router and contact your provider. If the problem is only on a specific device, try clearing the cache or using a different browser. You should also make sure that the device (not the memory card!) has at least 10% of the memory.

What to do if the wifi icon is missing

If the icon itself has disappeared, you should make sure that wifi mode is enabled. If there is no option to enable wifi, or the icon does not appear, you will have to reflash the smartphone or update the laptop drivers.

So, in the article all the most common problems with wi-fi Internet access were considered, and ways to solve them were also proposed. If you read this article, faithfully followed all the above recommendations, but your wi-fi still didn’t work, feel free to take your device to a service center, since you (most likely) won’t be able to fix the problem at home.

As practice shows, the biggest problems for users when working with Wi-Fi and routers are not caused by the connection process and not even the setup process. The biggest problem is the moment when, after setting up, the Internet regularly disappears, a message about an interrupted connection constantly pops up, or just not a single site can be opened on the laptop. In this article, we will try to find out what causes such problems, and what to do if Wi-Fi turns off on a laptop.

The reasons for automatic network shutdown are quite common.

What could be more frustrating than experiencing connection drops when working on a laptop? Just now everything was fine, and you calmly watched the movie online, and now the playback stopped, the movie paused, and the Internet disappeared altogether. You may encounter this problem for a variety of reasons. The most common are the following:

1. Your laptop is in battery saver mode. This leads to the fact that after a set period of time when the device is completely idle, the wireless connection is automatically terminated, 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 disconnections. This happens, as a rule, automatically and imperceptibly for 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 signaltransmitted over the cable may cause the wireless connection of the router and laptop to turn off automatically.

1. The router through which you access the Internet is unstable, constantly freezes, spontaneously reboots. In this case, Wi-Fi in 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 incorrect or outdated wireless network adapter driver. 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 if 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 elements of the system and certain components of the PC. If any of them is idle without work for a long time, it is turned off by the system automatically. Windows does this in order to save battery power, which is sometimes the only source of power 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 the Power plan setting that is currently installed on your system by default. Everything you need is under 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 get rid of the situation when the Internet is turned off at the request of the operating system.

Weak router signal

Generally, a weak signal coming from a Wi-Fi router can cause the connection to the network to drop out on a regular basis. Since the signal of the router is the most common radio wave, a variety of factors affect its power, which can also affect the quality of the connection. Not always the remoteness of the laptop from the router is the main reason for the decrease in signal strength. These may 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 considering revising the location of the router or expanding the network radius with the help of 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 shows an error about the loss of connection.

Metal objects between the Wi-Fi router and the laptop also significantly reduce the stability of the connection on the wireless network through which you access the Internet. Keep this in mind when organizing your home LAN.

Weak network signal

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

Unstable operation of the router

If you observe unstable operation of the router, which leads to a regular disconnection of the wireless connection, we recommend that you restart the device several times and closely monitor its further work. Or go to its control panel, check for software updates and install them if necessary. Since the router is running a special operating system, it, like any other, can accumulate system errors, work not quite stably and require periodic updates.

A complete reset of the router may also help. We recommend doing this only if you know its settings for your provider and can configure it again after the reset. Otherwise, contact the provider through the official website or by calling the hotline.

Driver failure

If the driver for the wireless network adapter has not been updated in your laptop for a long time, or if you began to observe problems with disabling Wi-Fi after the last reinstallation of the operating system, it may well be that an outdated or not the most suitable driver is installed. We recommend that you find out the manufacturer of the network adapter installed in your laptop and download the latest driver. We recommend doing this without fail on the official website of the manufacturer.

Conclusion

Whatever the reason for your laptop's Wi-Fi dropping out, one of the troubleshooting steps provided can help you get your network back to normal. If you tried all the instructions in this article, but none of them helped to identify the cause and get rid of the problem, you should contact the service center to test your router and network adapter in your laptop, as the problem, apparently, lies somewhat deeper.

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

Wifi signal dropped suddenly

turned off the router. Try restarting it by turning off the power for a couple of minutes and turning it back on.

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

Also, it is worth checking the settings of the power supply scheme used.

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

Didn't help and WiFi is turned off on the laptop anyway? Take it to the service.
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 side of the router. Try to reset its settings to the factory settings using the "Reset" button and set it up again.

If it doesn't work, take it in for repair.

Poor or unstable Wi-Fi signal strength

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. recently in apartment buildings this is some kind of direct punishment. There is a router in almost every apartment, and in every entrance there are a dozen or two networks. In this case, there are two ways out: the right one and the cheap one.
—Correct option but more expensive. Why? And because you have to buy equipment operating at a frequency of 5 GHz, since 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 a computer and a laptop will also need to be bought additional adapters - that’s a couple of thousand more. But things are worse with smartphones and tablets - 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.
- A cheap option - time-consuming and hemorrhoids. 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 still have to drag most of the devices closer to the modem or router, because even if the selected channel is free, the interference can come from busy neighbors. And you can't get away from it. Just wrap the house with foil in 5 layers.

I have no networks in the 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 the maximum coverage area, it should be located as close to the center of the dwelling as possible. If you have points where Wi-Fi from the router still does not finish, then you need to install an additional device - a repeater.

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

Do not forget that the reason that WiFi is turned off can be software or hardware router malfunction.

In my memory, there is one case with D-Link DIR-615 K2. The owner complained to me - "Wi-Fi disappears!". 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 safely eliminated.
Another case was with a device from QTech, where the contact of the internal antenna fell off when it fell off the table. The manufacturer took pity on the solder. Opened, soldered the antenna and WiFi does not disappear. Although, if you are not friends with a soldering iron, then if you suspect that Wi-Fi disappears due to a hardware malfunction, take the device to a service center.
