Why is Wi-Fi interrupted? Solving the problem of loss of Wi-Fi signal and low speed over a wireless network. Troubleshooting connection problems in the router

Very often there are cases when Wi-Fi on a laptop turns off on its own. Now we will figure out why the Internet disappears via Wi-Fi and how to solve this problem. If you came to this page, then you most likely already have this problem. We connect our laptop to Wi-Fi, the Internet works, but sometimes it disappears. There is one important point here: Wi-Fi does not turn off completely, but simply goes into the status “No Internet access” or “Limited” (and a yellow exclamation mark appears). Well, the Internet doesn't work. Although, there are times when the computer completely disconnects 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 Wi-Fi connection disappears periodically, or after waking up from sleep mode. There are times when the Internet stops working for a few seconds and then appears again. In any case, this creates a lot of inconvenience. You have to wait, reboot the laptop, downloading files, watching movies, etc. are interrupted.

Important point! We will look at solutions when the Internet turns off 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 with the Wi-Fi router, or some kind of problem with the Internet provider.

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

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

The main reasons for losing the connection to the router:

• There is interference on the channel on which your Wi-Fi network operates. Or, a weak wireless signal.
• Disabling the Wi-Fi adapter to save energy (Wi-Fi disappears when waking from sleep mode)
• Unstable operation of the Wi-Fi adapter driver.
• Problems with the router

I will show using Windows 7 as an example. If you have Windows 8.1 or Windows 10 and the Internet also disappears every 5 minutes (maybe more often or less often), then these tips will suit you. As for Windows 10, it is now full of problems with drivers. Therefore, if the connection in the “ten” is broken, I would first advise experimenting with the drivers of the wireless adapter and try to follow the recommendations from this article:.

Wi-Fi disconnects due to interference and weak signal

Our home wireless network operates on a specific channel. As a rule, there are many other neighboring networks within a radius that can cause interference. Interference may also come from other household appliances. And coupled with a not very stable wireless network signal, this can lead to a disconnection of the Internet on the laptop. A yellow exclamation mark "without internet access" may appear and work again after a while.

Also, disconnection can occur due to a poor signal when you move far from the router, and on the laptop, where the signal strength is displayed, one or two bars remain. In such cases, the connection may disappear altogether. If the Internet constantly cuts out in those rooms where the Wi-Fi network signal is weak, then we need to strengthen the signal of our network so that the connection is more stable. I wrote about this in the article: .

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

This is what changing the channel looks like on a Tp-Link router:

Please note under what conditions the Internet connection occurs. This could 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 happens because Windows turns off the Wi-Fi adapter during sleep mode 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 from turning off, and set maximum performance when running on battery power and mains power.

Let's set up the power supply first. Press the keyboard shortcut Win+R. Copy the 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 next to this plan on the link Setting up a power plan.

Next we open Change advanced power settings. Looking for a section Wireless adapter settings, open it and install Maximum performance when operating from mains and battery. Click Apply And Ok.

We prohibit disabling the Wi-F adapter to save energy

Disabling the adapter will not save us a lot of electricity, but problems with 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.

Device Manager will open. Find and open the tab Network adapters. Then, right-click on the Wi-Fi adapter (its name should contain the words "Wi-Fi", "Wireless") and select 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 will work via Wi-Fi.

Internet may disappear due to driver problems

If the Wi-Fi adapter driver is outdated, or the wrong driver is installed, then a variety of problems with the wireless connection may appear. Open Device Manager like I showed above (press Win+R and execute the command mmc devmgmt.msc). Open the tab Network adapters. Find your wireless adapter (the name will include "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 correctly.

Even if there is no warning icon, try updating the driver for this adapter. Perhaps this will solve the problem with Wi-Fi disconnecting. Just don't update 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 in more detail about driver installation in the article.

You can also try selecting one from already installed driver versions, removing the driver, or rolling back it. I described all these actions in more detail using Windows 10 as an example in a separate article:.

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 this at the beginning of the article. On computers, the connection status becomes "no internet access".

And on mobile devices (smartphones, tablets), the Internet simply stops working. And after such failures, you always need to reboot the router, only after that the Internet starts working again. Moreover, such interruptions usually happen at moments when the router is under heavy load: we are downloading something (especially from torrents), watch online videos, play online games, connect some other devices to Wi-Fi, etc. And basically, this problem occurs on inexpensive routers.

This is understandable, they simply cannot withstand the load and “fall”. Only a reboot saves. My friend has exactly the same (which is from the Kyivstar provider). After connecting the smartphone and laptop, everything works well. As soon as you turn on watching online video, after a while the Internet disappears.

What you can do:

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

It seems like I didn't miss anything. Write in the comments how you managed to get rid of this problem.

In this lesson we will talk about what needs to be done if the Wi-Fi network has disappeared or you cannot connect to the network from a certain device?

We will look at the sequence of actions, after which you can determine what is the cause - the Wi-Fi router or the device on which Wi-Fi does not work.

We have prepared 2 options - a text article and a video tutorial. Check out both options as they complement each other.

Video tutorial:

Article:

I recently received this question:

“hi, tell me, I bought a zyxel router.. the computer works, but the laptop does not via Wi-Fi. It says an unidentified network.. what should I do?”.

As I understand from the question, the user’s PC is connected to the router with a cable and has access to the Internet, but the laptop does not connect to the router via Wi-Fi.

In this article I will try to tell an approximate sequence of actions to solve this kind of problem. As an example, I will give screenshots of the settings of my home router TPLINK models TL-WR841N.

Stage #0. The easiest step is to start by simply rebooting both devices, perhaps one of them is “a little stuck.”

Stage #1. First, you need to check the wireless access settings in the router settings: name for Wi-Fi hotspot, openness to discovery, communication standard. For diagnostics, you can remove the password and encryption on Wi-Fi.

"Network name"- this name should appear in the list of Wi-Fi networks on the laptop.

"Mode"- this is a data transfer mode setting, it is better to select it with the maximum number of modes.

"Enable wireless broadcasting"- this is a general activation of wireless mode.

"Enable SSID Broadcast"- this setting is so that other devices can detect the router. If you do not select this setting, you will end up with a hidden network that not all devices can connect to.

For diagnostics wireless connection protection can be disabled.

In other routers, these settings may look different, but for diagnostics they must be set in the same way.

Here is an example of settings for the router D-LINK models DIR-615:

Stage #2. On the laptop, you need to check in the device manager that the Wi-Fi adapter is working properly.

If the Wi-Fi adapter does not work correctly, then you need to reinstall the driver for it.

If you don’t have a driver or are in doubt about an existing driver, then you need to go to the laptop manufacturer’s website and search there.

After this you can do search for wifi networks, find your network, and try to connect to the router.

If the connection is successful, check your Internet access.

If the connection fails, check the connection to the router from another device, for example, a smartphone.

Stage #3. If there is no connection to the router from other devices (or there is a connection, but no access to the Internet), then the problem is most likely in the router.

In this case, you can check the antenna mount on the router, perhaps reset the settings or update the router firmware, then reconfigure the Wi-Fi settings and check the connection to it again. If these steps do not help, you will have to take the router to a service center or replace it with another one.

Stage #4. If the connection was successful from other devices, then the problem is most likely in the laptop.

In this case, you need to check the Wi-Fi settings on the laptop again, perhaps reinstall the Wi-Fi driver, or remove the Wi-Fi adapter in the device manager and find it again.

One of the reasons for Wi-Fi malfunctions may be OS updates. I recommend additionally checking whether OS updates were installed immediately before the failure occurred. If there were such updates, you can try to roll back them and check your connection to the router via Wi-Fi again.

The most radical method - reinstalling the OS - should be used in the very last case, when none of the software configuration options has brought a positive result.

If these steps do not help, then you need to take the laptop to a service center; the Wi-Fi module is usually made in the form of a separate board and you can try to replace it.

Stage #5. When everything works - Don't forget to set up a password and encryption for Wi-Fi on the router.

If you have questions about the article, ask them in the comments.

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

You have a network: computer - Internet - laptop, but the signal on the laptop constantly disappears. Sound 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 are sources of failure; 3) problems with the module (rare, but it happens); 4) the router itself has broken down (rarely, but it also happens).

All these reasons are not very common, but they do occur. But there is another reason that rarely anyone pays attention to, but, nevertheless, it is the most common.

What do you do to ensure that your laptop retains its battery charge for as long as possible? Well, well, think. That's right: you put it into energy-saving mode. By the way, very often this mode is configured in laptops by default. Yes, this is very true, because the battery retains its charge longer. But this is precisely where the reason for the constant Wi-Fi interruption 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 gist of it comes down to this.

"Start" - "Control Panel" - "System and Security" - "Power Options". Now you see: you have a checkmark in the “Energy Saving” item. Right there you have an active system link “Setting up the power supply scheme” - 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 “On Battery” sub-item 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 this that your Wi-Fi disappears. The solution is trivial: select the option “On battery: maximum performance”. Click "Apply" and "Ok". All.

There is another option to fix the Wi-Fi problem. 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 operation (for example, Qualcomm Atheros AR9485WB-EG Wireless Network Adapter, in general, the word Wireless should be there). Double-click on this adapter with the left mouse button. A window with the properties of your adapter will open. Open the “Power Management” tab and uncheck the “Allow the computer to turn off this device to save energy” option. Click on "Ok". All.

Happy dancing with a tambourine, friends, and see you again!

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 a very 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 reconsidering 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 an outdated or not the most suitable driver was installed. We recommend that you find out the manufacturer of the network adapter installed in your laptop and download the latest driver. We definitely recommend doing this on the manufacturer’s official website.

Conclusion

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

Without exaggeration, our modern age can be called information age. Every day, people from all over the world go online to find the necessary information and “visit” their friends or relatives. Some people love computer games, which attract with their beautiful virtual world, which can also be accessed through the World Wide Web. What can I say, many of us almost literally live there. But sooner or later the Internet periodically disappears, which causes certain emotions.

Why does this happen and who is to blame for it? But most importantly, what can be done in this current situation?

And the whole world is not enough, or Who gives us the Internet

Without a doubt, and hardly anyone will argue with this, the Internet is a significant achievement of which a person is capable. We can say that this is a whole world where there is almost everything you might need. These are electronic magazines, books, useful articles on various sites and much more. With the help of the Internet, you can learn something new, improve yourself, and even find a suitable job.

But here's an interesting question: "Who gives us the Internet?" In our daily life there are a large number of terms that come from different languages. The word provider is no exception - something “foreign” is immediately visible in it. Meanwhile, this definition hides nothing more than a company that provides access to the World Wide Web to residents of many countries.

There are primary and secondary providers. The first of them distribute traffic in large volumes, while the second rent channels from them. Residents of almost all countries of the world use the services of secondary providers.

Why is the connection lost?

We figured out where the Internet comes from. Of course, this is superficial, but if you need to know more, it is better to visit the sites yourself. We are more interested in why the Internet periodically disappears. Sometimes this can happen due to the fault of the provider, although, fortunately, not so often.

But let’s not blame anyone, but rather let’s figure it out and list many probable reasons for this behavior of the Internet.

The most obvious is mechanical.

Some time ago, the Internet was connected through the telephone network. The speed was very low, even downloading one good picture took several minutes, and you couldn’t make a call - the line was busy. Then, however, the speed improved a little, and the line became free for phone calls. Now, no one can be surprised by a fiber-optic cable, and the development of communications does not stand still, it all comes down to increasing bandwidth.

Now, almost every subscriber has a channel connected not directly to a computer, as was often the case before, but to special equipment that distributes it to other devices (laptop, tablet, smartphone, etc.). And if someone cannot access the site, he wonders why the Internet through the router periodically disappears?

A network loss can be mechanical in nature: damage to the cable that goes to the devices, or the device itself (router or modem). It is worth carefully inspecting the device, as well as the cable; perhaps there are places where it has become frayed or exposed. A break in the internal wires is also possible.

Hardware failure

If the equipment is in perfect order, but there is still no Internet, then the reason may lie elsewhere. The thing is that often the settings made when connecting the router for the first time are lost. Perhaps due to some error, but the result is obvious - you cannot access the Internet.

A router is a rather complicated device, in which are hidden:

• CPU;
• electronic memory;
• firmware

Some models may even have a full operating system. Such a problem, when the WiFi Internet periodically disappears, may lie in both hardware and firmware. It may have been incorrectly updated, which also negatively affects the operation of the equipment.

You can solve the problem by resetting your router. This can be done in different ways:

1. Launch your browser and enter the desired IP address in the address bar. Depending on the hardware model, this may be 192.168.0.1 or 192.168.1.1. In the window that appears, you need to enter your username and password. If they have not changed, then the default is admin. Next you need to act based on the router model. You need to look for an item related to resetting to factory settings.
2. This method is easier - on the back of the device there is a small black button with the inscription WPS RESET. Sometimes it can be hidden in the case, and to get to it you will need a regular sewing needle. To reset the settings, you need to hold the button pressed for 10 seconds.

Some models may not have such a button at all. In this case, you can solve the problem when the Internet on your computer periodically disappears only using the first method.

Repair work

Sometimes the connection may be lost even through no fault of the subscriber. The cable may be damaged not within the apartment, but outside it. For example, builders started repair work at the entrance, during which the possibility of accidental damage to the cable cannot be ruled out. In this case, it is worth contacting the provider who is responsible for troubleshooting.

Emergency situations

But in some cases, the Internet may actually be interrupted due to the provider. The reason may be a hardware malfunction. Or it could be an emergency - maybe the cable was broken somewhere, or something else. In this case, the Internet may be absent for from several minutes to hours.

In this case, all that remains is to contact the hotline and report the problem. Then calmly wait until she is eliminated. Such cases are rare, but apt. Therefore, it is worth considering other reasons why the Internet on a laptop periodically disappears.

Viruses

Another equally popular reason for the lack of Internet may be related directly to the computer, in particular the presence of viruses. Such tenacious “microorganisms” are familiar to any user. Moreover, installed anti-virus software (software) does not provide a complete guarantee that a virus will not be accidentally picked up. And if the subscriber spends most of his time in the virtual space, then the risk increases significantly.

Every year there are about a hundred more viruses, if not more, and many companies are simply not able to keep up with this development. It is noteworthy that there are malicious programs that block access to the network.

To minimize risks, you should use only licensed antivirus products. Every operating system has a firewall, which should not be disabled unless you have an antivirus. This will protect yourself from infection.

And in order to ensure that the situation when the Internet through the router periodically disappears as rarely as possible, you need to follow some computer security measures. Under no circumstances should you click on suspicious links, especially from sent emails. It is also highly recommended not to download files from unverified sites. In addition, every time you connect any storage device (external hard drive or flash drive) to your computer, you should check it for viruses.

Unsatisfactory signal

Each router is equipped with a Wi-Fi transmitter and has an antenna or even several. And if there is no Internet, then the first thing you should do is check the antenna contacts. They can be removable or non-removable. In the first case, problems should usually not arise. Otherwise, you will first have to make sure that the wireless router is out of warranty. Only then can you disassemble the device and inspect it from the inside - perhaps the antenna contact is broken.

If the Internet on your laptop via WiFi periodically disappears, this may be due to a weak signal. If, for example, everything is in order on the computer, but there is no connection on the laptop, you should place the wireless router in a place from where the signal spreads evenly throughout the apartment.

It is worth paying attention to what frequency the equipment operates at. If it is 2.4 GHz, then a working microwave oven or landline radiotelephone may interfere with the transmission of the Wi-Fi signal.

It's all about the firmware

It’s not uncommon for there to be no Internet precisely because of bad firmware. In this case, if there is a connection, it does not work properly, periodically breaking off, or other troubles occur.

In this case, you can try updating the firmware. This is special software that is present on every router or modem. It is this that controls the operation of the processor, memory, traffic and other necessary tasks.

But when equipment, for example, TP-Link, loses the Internet periodically, updating the software does not always help. Therefore, it is better to first visit various forums and study reviews.

How to update software

If you still need to perform the update operation, you must visit the manufacturer’s official website. There you need to download the required file depending on the router model. After this, you need to log into the equipment by entering the IP address (described above).

On the right side you need to find the “System Tools” item, but if the menu is in English, then System Tools should be written. Then you need to look for "Firmware Update" or something like that. Here you need to click on the “Browse” button (or something else) and specify the path to the downloaded file. Then all you have to do is click on the “Update” button. After this, the equipment should restart itself.

Upon completion of the procedure, you need to reconfigure the router and check whether the Internet is lost or not. In most cases, this helps solve the problem.

Conflict situation

Another reason when the Internet periodically disappears may be related to IP addresses. As a rule, within a single computer network there should not be devices with the same addresses. The subnet is an exception and this is acceptable here. This can happen due to the fact that the router automatically begins to distribute network addresses to recently connected devices. In this case, he can assign the same IP to two PCs.

In this case, you should try to connect to the Internet; an error will appear on the monitor with the text “IP address conflict with another system on the network.” You can solve the problem like this: turn off the Internet, then turn it on again - the equipment must assign a new address. Or assign any free IP yourself.

Guardianship of antivirus programs

Antivirus software can also cause you to be unable to access any website. On the one hand, it can be understood, because it protects us from attacks by harmful “microorganisms”, but sometimes the antivirus does this too much, blocking all incoming connections. As a result, we sit without the Internet, not knowing what to do.

To eliminate the problem when the Internet periodically disappears, you need to go to the properties of the network card. It can be external, but is often built into the motherboard. To go there you need to do the following, depending on the installed operating system:

• If it is Windows XP: the "Start" menu, then the "Settings" item, then select "Network Connections". A window with an active connection will appear - you need to double-click on it with the left mouse button (LMB).
• If it is Windows Vista or Windows 7 (8, 8.1, 10). Next to the clock there will be an icon of a drawn monitor with a cable. You need to right-click on it and select “Network and Sharing Center.” A window will open in which the desired link Change adapter settings will be on the right. We click, in another window that appears we see the connection, on which we also double-click LMB.

As a result of the manipulations, there will be another window where we are interested in the “Properties” button. After clicking, connection parameters will appear, where you need to find your antivirus and uncheck the box to the right of it. After that, click the "OK" button and restart the computer.

Thanks to the actions taken, you can forget about the fact that the Internet periodically disappears and safely go online. Only now the defense will be weakened.

Bottom line

It also happens that all of the above methods cannot help solve the problem. Then all that remains is to call a professional to your home, who should fix everything. True, it is not free, and it is not known how long it will take. But there is still hope that these methods will still help.
