The laptop is disconnected from the wifi network. We solve the problem with disabling WI-FI on a laptop

All tips

Happy laptop owners sometimes have situations when wifi suddenly turns off and the Internet no longer works. Such a problem is not uncommon and can constantly arise according to completely different reasons. This post will discuss how to solve this problem.

Imagine you are reading a news article, watching an online movie, chatting with friends in instant messengers or through voice communication when suddenly access to the Internet is turned off, the computer stops seeing available connection, and precious minutes are constantly spent on its renewal, which are always not enough. In this regard, before proceeding to solve the problem disable wifi, it is worth understanding some of the reasons leading to this error.

The most common reason for intermittent disconnection of the Internet connection lies in system utility laptop power saving. The program, at certain intervals of machine downtime, breaks the wireless connection due to which the Wi-Fi module stops seeing and exchanging data with the router in order to save energy.

An unlikely but valid reason is when the access point is located too far from the receiving device or works behind an obstacle. As a result, the signal strength becomes so weak that wireless adapter laptop is not able to catch it, as a result, the connection is disconnected. That is why it is so important to purchase devices with a powerful transmitter.

Often, an Internet signal transmitted over a cable and converted into a wireless router in a router wired connection, too weak and, despite the working Wi-Fi modules, access to the network is impossible. Moreover, weak signal cable connection may cause automatic shutdown hotspot and laptop connection.

Unstable operation of the wifi router, periodically manifested in reboots and freezes. In such cases wireless device on the computer will do automatic restarts, and the connection will disappear, disconnect and resume again after full recovery access point operation.

Outdated or inappropriate adapter driver wireless wifi Connecting a laptop also causes intermittent disruption, or the computer does not detect available wireless connections at all.

The above problems are the most banal, but other reasons also occur and it must be remembered that each specific case is in some way unique and its resolution requires a whole range of measures to restore the lost connection.

Disable power saving mode

Since all laptops have built-in autonomous elements nutrition, they are usually accompanied by special programs or used standard means operating system to make power saving efficient. 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 power saving icon there. In the window that opens, you need to find and select the power 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 the maximum performance mode, in other words, prevent the program from turning off the wireless adapter. Now operating system will not be able to interfere with the wireless connection and interrupt its operation.

Weak access point signal

A variety of obstacles can affect the quality of the wifi router signal, from the walls of rooms to electrical appliances. Often, the cause of signal loss can be a malfunction of the antenna of the transmitting Wi-Fi device.

To eliminate this problem, you should act by trial method. It is necessary to identify the cause of 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 there is a suspicion of a weak signal coming over the wire from the provider, then it is worth contacting the customer support service and finding out the cause of the problem, due to which access to the Runet is lost. When we are talking about the network provided mobile operator, then it may be worth trying to amplify the signal by changing the localization of the transmitting device.

WiFi distributor problems

In case of obvious problems with a wifi router, a series of reboots can help. If the device does not work as required and continues to disconnect, you can, as an option, check the settings of the access point, perhaps the provider has changed some parameters. You can also check for updates on the hardware manufacturer's website and, if available, update the software through the settings menu.

Problems in drivers

If the working machine is not the first freshness, 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 of the network adapter and download new version from its official website, and then install it on a personal computer.

If you have any problems related to disabling Wi-Fi, you should use the above tips and only then, it may make sense to contact a specialized service center for detailed equipment diagnostics. Now you know why wireless connection can be torn and able to find a solution to this problem.

Very often there are cases when Wi-Fi on a laptop turns off by itself. Now we will figure out why the Internet over Wi-Fi disappears, and how to solve this problem. If you have come to this page, then you most likely already have such a problem. We connect our laptop to Wi-Fi, the Internet works, but sometimes it disappears by itself. Here alone important point: Wi-Fi does not turn off at all, but simply goes into the status "No Internet access", or "Limited" (and yellow appears exclamation mark) . Well, the internet doesn't work. Although, there are times when the computer is completely disconnected from the wireless network. This problem is not uncommon on Windows 7, Windows 8, and Windows 10. So it doesn't matter what operating system is installed on your laptop.

As a rule, the connection to Wi-Fi is lost periodically, or after waking up from sleep mode. There are times when the internet stops working for a few seconds and then reappears. In any case, this creates a lot of inconvenience. You have to wait, restart your laptop, file downloads, watching movies, etc. are interrupted.

Important point! We will look at solutions when the Internet is disconnected on only one laptop. That is, other devices that are connected to your router continue to work normally. If the Internet disappears on all devices, both via Wi-Fi and cable, then this is already a problem in the Wi-Fi router, or some kind of problem with the Internet provider.

If you have a problem observed only on one computer, then now we will try to solve it.

Why does the Wi-Fi connection disappear on a laptop?

The main reasons for disconnecting the connection with the router:

Interference on the channel on which your Wi-Fi network operates. Or, a weak wireless network signal.
Shutdown wifi adapter to save power (Wi-Fi disappears when waking from sleep mode)
Unstable operation of the Wi-Fi adapter driver.
Problems with the router

I will show Windows example 7. If you have Windows 8.1 or Windows 10 and the Internet also disappears every 5 minutes (may be more or less) then these tips are for you. As for Windows 10, there are now a lot of problems with drivers. Therefore, when the connection is broken in the "top ten", I would first of all advise experimenting with the wireless adapter drivers.

Disconnecting Wi-Fi due to interference and weak signal

Our home wireless network operates on a specific channel. As a rule, there are many others in the radius, neighboring networks that may interfere. Interference can also be from others household appliances. And in conjunction with a not very stable wireless network signal, this can lead to disconnection of the Internet on a laptop. May appear yellow Exclamation point"without access to the Internet", and after a while work again.

Also, a shutdown can occur due to bad signal, when you move away from the router, and on the laptop, where the signal strength is displayed, there are one or two divisions left. In such cases, the connection may disappear altogether. If the Internet is constantly cut off in those rooms where the signal is weak WiFi networks, then we need to strengthen the signal of our network so that the connection is more stable. I wrote about this in the article: how to strengthen the signal of a Wi-Fi network? Increase Wi-Fi range.

As for problems with interference, here you need to experiment with the channel on which your network operates. You can try with special program find the freest channel, and set it in the router settings. Or, just ask some static channel in the router settings. How to do this, I described in detail in the instructions: how to find a free WiFi channel, and change the channel on the router? If you already have a static channel, then set it to Auto.

This is how the channel change on the Tp-Link router looks like:

Pay attention to the conditions under which disconnection from the Internet occurs. This can be for example moving around the house, or only in certain places (rooms). Then it will be easier to find the cause and eliminate it.

What to do if the Internet disappears after waking up from sleep mode

This is because in the dormant Windows mode disables the Wi-Fi adapter to save power. And when you exit sleep mode, the adapter can no longer work normally, and you need to restart the laptop. Also, problems are often observed when the laptop is running on battery power. We need to disable the wireless adapter, and set the maximum performance when running on battery and mains.

Let's set up the power plan first. Press keyboard shortcut Win+R. Copy command control powercfg.cpl in the "Open" line, and click on the button Ok.

A window with power plans will appear. I advise you to choose Balanced. Next, click on the link next to this plan Setting up a power plan.

Next we open Change advanced power settings. We are looking for a section Wireless network adapter settings, open it and install Maximum performance during mains and battery operation. Click Apply and Ok.

We forbid disable Wi-Fi power saving adapter

Turning off the adapter will not save us a lot of electricity, but problems in its operation may appear. Therefore, you need to prevent Windows from turning off the adapter.

Click Win+R, copy the command mmc devmgmt.msc and press Ok.

The device manager will open. Find and open a tab Network adapters. Then, click right click mouse to wifi adapter (its name should contain the words "Wi-Fi", "Wireless") and choose Properties.

Go to the tab Power Management, and uncheck the box Allow this device to turn off to save power. Click Ok.

We reboot the laptop, and check how the Internet via Wi-Fi will work.

Internet may drop due to driver issues

If wifi driver adapter is outdated, or the wrong driver is installed, then a variety of problems in the operation of the wireless connection may appear. Open device manager as I showed above (press Win + R, and execute the command mmc devmgmt.msc). Open a tab Network adapters. Find your wireless adapter (name will be "Wi-Fi", 802.11n, or "Wireless"). There may be a yellow exclamation mark next to the adapter. This means that the device is not working properly.

Even if there is no warning icon, try updating the driver for this adapter. Perhaps this will solve the problem with turning off Wi-Fi. Just update not through device manager (the system will say that the update is not needed), and download the driver from the official website of your laptop manufacturer. Required for your model and your operating system. Download and install the driver. I wrote more about installing the driver in this article.

Still, you can try to choose one with already installed versions driver, uninstall the driver, or roll back it. I described all these actions in more detail using the example of Windows 10 in a separate article: solving problems with the wireless Wi-Fi adapter driver in Windows 10.

What to do if the Internet periodically disappears on all devices?

If your Internet connection disappears simultaneously on all connected devices, then the problem is already in the router. I wrote about it at the beginning of the article. On computers, the connection status becomes "no internet access".

And on mobile devices (smartphones, tablets) the internet just stops working. And after such failures, you should always restart the router, only after that the Internet starts working again. Moreover, such breaks usually occur at the moments when the router goes huge pressure: downloading something (especially from torrents), watch online video, play Online Games, we connect some more devices to Wi-Fi, etc. And basically, this problem is observed on inexpensive routers.

This is understandable, they simply can not withstand the load, and "fall". Saves only reboot. My friend has exactly the same problem with Tp-Link TL-WR741ND (which is from Kyivstar provider). After connecting the smartphone and laptop, everything works well. Just turn on watching online video, after a while the Internet disappears.

What can be done:

Connect the Internet without a router, directly to the computer, and check the operation. To eliminate breaks on the provider side.
Updating the firmware of the router, this very often helps. We have instructions for all popular router manufacturers on our website.
Disable torrent clients on devices (if any). They create a load, due to which the Internet disappears.
If you have Internet through a 3G / 4G USB modem that is connected to a router, then such breaks most likely occur on the provider's side.
Well, buying a more powerful router.

It seems to have missed nothing. Write in the comments how you managed to get rid of this problem.

Wi-Fi is a technology that allows electronic devices transmit data or connect to the Internet wirelessly. Nowadays, Wi-Fi usage is becoming very common and we may see this technology being used by a wide range of devices such as smartphones, tablets, game 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 WPA2 encryption to prevent unauthorized access to the network. If you do not have sufficient knowledge to set up a home or office network 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 periodically disappears. Usually, if there is no activity, the phone or tablet loses connection with the wifi router and does not see the network until Wi-Fi is restarted on mobile device. There may be several reasons why the Wi-Fi connection is lost, in this article we will consider several options for solving the problem when Android loses the Wi-Fi network.

If you are facing Wi-Fi disconnection problem on your Android device, try the following settings and you will be able to connect your device wirelessly without much hassle.

Wi-Fi network overflow

The biggest hurdles for wifi signal create neighboring wireless networks. The problem is that most WiFi devices operate in the already occupied 2.4 GHz band, and high density 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 at the same time. The 2.4GHz 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 on this band. If your router can operate in the 5 GHz band, use it to solve the problem of Wi-Fi network congestion.

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: If channels 1, 6 and 11 are used, there will be no interfering overlap as these are non-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 dropdown menu, select desired number channel.

Most manufacturers use various methods to increase battery life. Users Android smartphones are forced to enable such power-saving features in their devices. One such feature is to turn off Wi-Fi when the phone is inactive or when the device has low level battery charge. Such WiFi features in sleep mode create problems connecting to the network as needed.

Solution: Just adjust 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 networks– Wi-Fi and select Advanced – WiFi in sleep mode do not select “Do not turn off”.

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

Change DNS servers

Changing the 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 this famous network, you will have to "forget" it and then reconnect it. When you see the password entry window, click on Extra options and select “Static” from the IP settings in the drop down menu. Then scroll down and enter the IP address of the DNS server you would like to use in the DNS1 and DNS2 box. Now enter wifi password and connect the network.

Reset to factory settings

If none of these methods help, run hard reset your Android device. If you're having issues after doing this where your Wi-Fi connection is lost, then it could be a hardware issue. You may need to take your device to a service center to have the problem fixed.

We have covered the most common Wi-Fi disconnection causes that occur in Android devices. We hope this will help in solving the problem and allow you to set up a stable Wi-Fi connection. In addition, pay attention to specialized applications, because in google store Play has a lot of apps that will help you get a reliable connection. Some of them are Wi-Fi Fixer, Fix My Wi-Fi, Wi-Fi Analyzer and others.

Very often there are cases when Wi-Fi on a laptop turns off by itself. Now we will figure out why the Internet over Wi-Fi disappears, and how to solve this problem. If you have come to this page, then you most likely already have such a problem. We connect our laptop to Wi-Fi, the Internet works, but sometimes it disappears by itself. There is one important point here: Wi-Fi does not turn off at all, but simply goes into the status "Without access to the Internet", or "Limited" (and a yellow exclamation mark appears). Well, the internet doesn't work. Although, there are times when the computer is completely disconnected from the wireless network. This problem is not uncommon on Windows 7, Windows 8, and Windows 10. So it doesn't matter what operating system is installed on your laptop.

If you have a problem observed only on one computer, then now we will try to solve it.

The failure can also occur as a result of power outages or due to a large number subscribers. All these reasons give one effect - the router freezes. To fix it just restart it. Unplug the WiFi router's power supply from the outlet for 7-10 minutes, then turn it on again. Unfortunately, this phenomenon cannot be completely eliminated, since budget devices just can't bear high loads without negative consequences and at some point they will still fail.

What to do if WiFi does not work on a laptop: Video

Wireless Internet is very convenient, modern, but it is not always problem-free. Some failures that cause a lot of trouble for users occur on their own time after time. Today we will talk about why the Wi-Fi network disappears. As a rule, such incidents are relevant for laptops, which, it would seem, are simply designed to work specifically with wireless networks, supporting the idea of creating an ideal mobile solution.

Since there may be several causes of the problem, we will consider each separately below. In general, to begin with, you will need to do some diagnostics and check if there are any problems with the power supply of the router and the device itself. In the case of the first, everything is determined quite simply, to check the second, you need to try connecting other devices to the network - tablets, phones.

If everything works fine, it is possible that the problem is only with the computer, and you need to consistently check the operation and settings of its adapter.

energy saving

The next thing we should do if the Wi-Fi network is lost is to diagnose using the system. Click on the wireless network signal icon and find the item "Diagnosis of problems", and then follow the instructions. Perhaps this option will help you.

Open "Start" and in it find the "Control Panel" we need. Now we need the settings that are hidden under the Power Options icon.

There will be several options here, and if you do not want to set high performance, then you need to select at least "Balanced mode".

In case of unacceptability and this option, you can only set the consumption separately for the adapter. Click "Setting the power plan" next to the desired option.

Now "Change advanced options".

Here we scroll down and find the “Adapter Settings” item - you need to open the parameter tree, then open the “Energy Saving” sub-item again and set “Maximum Performance” in the “Battery” and “Network” parameters.

Everything that could be done here, you have done - now click "OK", "Save changes" and close the window.

The second option also, in a sense, depends on the power settings - it happens that when the user sends the computer to sleep, after turning on the adapter still remains in this mode.

Click "Start" again and click on "My Computer" and select "Properties".

Inside it will be a lot of equipment, but we are interested in network adapters. Having opened the tree with them, we are looking for the one with the Wi-Fi attribute and double-click the left mouse button.

Here we are looking for "Power Management" and uncheck the box "Allow the device to turn off to save power." Next, click "OK" and test how everything works. To be sure, the best option is to reboot the device after all these operations.

Sometimes the problem may be in the oxidation of the adapter contacts, not connecting it after cleaning or repair, or in the device drivers. In the first two cases, only mechanical intervention will help. To update the drivers, you need to find the name of your model and go to the official website of the manufacturer to download the necessary programs.

This is all that could be done on the computer side if the Wi-Fi network was lost, and now we will consider solving the problem on the side of the distributing point.

If the reason is in the router

If, after all the checks, you came to the conclusion that the problem is with the distributing device, then you can’t do much here: when the router is turned on and working normally, even without special settings and the provider’s cable plugged in, the network will be determined and should not disappear.

As mentioned above, check the power of the device - perhaps the contact is loose somewhere or the power supply is becoming unusable.

The problem may lie in the firmware that has flown down, but it’s quite difficult to identify this, because in the event of a failure you can get into the settings and visually everything will be fine, but the Wi-Fi network still disappears over and over again.

In any case, if the router is already malfunctioning, flashing it is unlikely to harm it. Just go to the official website of the manufacturer, open the instructions and download the firmware. If after that there are no improvements, then most likely you will have to go for a new router.

Why Wi-Fi Keeps Disconnecting: Video

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 translate 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". Here you have an active system link"Setting 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 energy 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". That's it.

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!

Setting up a Wi-Fi router is not so difficult, however, after that, despite the fact that in general everything works, a wide variety of problems are possible and the most common of them include the loss of a Wi-Fi signal, as well as low Internet speed (which especially noticeable when downloading files) over Wi-Fi. Let's see how to fix this.

I will warn you in advance that this instruction and solution do not apply to situations where, for example, when downloading from a torrent, the Wi-Fi router simply freezes and does not react to anything until the reboot. See also - all articles (troubleshooting, setting different models for popular providers, more than 50 instructions)

One of the most common reasons for a Wi-Fi connection to drop

First, about exactly how it looks and specific symptoms by which you can determine that the Wi-Fi connection is disappearing precisely for this reason:

A phone, tablet or laptop sometimes connects to Wi-Fi and sometimes doesn't, with almost no logic.
The speed over Wi-Fi, even when downloading from local resources, is too low.
Communication with Wi-Fi disappears in one place, and not far from the wireless router, there are no serious obstacles.

Perhaps the most common symptoms I have described. So, the most common cause their appearance is your wireless network's use of the same channel used by other Wi-Fi access points in the neighborhood. As a result of this, due to interference and “clogging” of the channel, such things appear. The solution is pretty obvious: change the channel, because in most cases, users leave the Auto value, which is set in the default router settings.

Of course, you can try to perform these actions at random, trying different channels until you find the most stable one. But you can approach the matter more reasonably - to determine in advance the most free channels.

How to find a free Wi-Fi channel

If you have an Android phone or tablet, I recommend using a different instruction:

First of all, download to your computer free program inSSIDer from the official site http://www.metageek.net/products/inssider/ . ( UPD: The program has become paid. But they have free version for Android). This utility will allow you to easily scan all wireless networks in your area and in graphical form will display information about the distribution of these networks by channels. (See picture below).

Signals from two wireless networks overlap

Let's take a look at what this graph shows. My access point, the site uses channels 13 and 9 (not all routers can use two channels at once for data transfer). Note that you can see that another wireless network is using the same channels. Accordingly, it can be assumed that problems with Wi-Fi communication are caused by this factor. But channels 4, 5 and 6, as you can see, are free.

Let's try to change the channel. General meaning- choose the channel that is as far as possible from any other sufficiently strong wireless signals. To do this, go to the router settings and go to setting up a wireless Wi-Fi network () and specify the desired channel. After that, apply the changes.

As you can see, the picture has changed for the better. Now, with a high degree of probability, the loss of speed over Wi-Fi will not be so significant, and incomprehensible disconnections - so frequent.

It is worth noting that each wireless network channel is 5 MHz apart, while the channel width can be 20 or 40 MHz. Thus, when choosing, for example, 5 channels, the neighboring ones - 2, 3, 6 and 7 will also be affected.

Just in case: this is not the only reason why low speed through a router or Wi-Fi connection is broken, although one of the most frequent. This can also be caused by unstable firmware, problems with the router itself or the receiver device, as well as problems in the power supply (voltage jumps, etc.). Learn more about the solution various problems when setting up a Wi-Fi router and working wireless networks you can read.

Problems with wifi connection any user of modern devices has ever experienced the Internet. Not stable internet(and even his complete absence) is usually very annoying, I 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 wi-fi connections with the Internet and ways to solve them.

Why wifi disappears - reasons

Reasons that could potentially lead to the lack of a stable wifi connection(or connections in general) is incredibly large, this is a banal removal to an excessively long distance, and the presence of any radio interference in the coverage area of the access point, 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 faults.

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 program reason no signal.

If your gadget is running less popular operating systems, such as symbian, windows mobile or even some kind of "self-written Chinese OS" software diagnostics it is impractical to carry out, 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 software kernel.

What to do if wifi is missing on a Windows laptop

Reasons for the loss wifi signal on a laptop can be conditionally divided into three categories:

If, when pressing the corresponding key on the laptop, the indicator wifi works 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 start key BIOS boot there may be another - carefully read the notification that appears when you turn it on (usually desired button written at the bottom right). It should be noted that in your BIOS versions may or may not be an option. turn on 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 performance indicators wifi module and the router are lit, but there is no signal, you should check if wifi is enabled in Windows itself. Right-click on 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”.

Cause unstable work wifi can be a high load on 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 in address bar browser's debug address: "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 simultaneous connection multiple 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 they are receiving feedback from your router (when it is on and working). 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, please note that this will affect battery life. Also, disable automatic hibernation - very common after waking up from sleep wifi adapter de facto remains disabled until the next reboot.

I lost wifi on my iphone, what should I 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 current version iOS.
If iOS update 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 should also be noted that not all android devices support pairing with wifi relayed through the 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 some specific device try clearing the cache or use 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 disappeared, you should make sure that it is enabled wifi mode. 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 wifi access on the Internet, as well as ways to solve them were proposed. If you have read this article, conscientiously 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) will not be able to fix the problem at home.
