There are no available Wi-Fi connections in Windows - solutions. “No connections available” - how to fix the problem No connections available

Useful tips

The misunderstanding, which we will touch on in our article, increasingly worries users of laptops connected to a wireless network. This misunderstanding is of a technical nature - the essence of the problem is the unexpected refusal of the built-in or external router to receive and transmit data.

In this case, the network icon in the tray takes on a characteristic appearance - a ladder crossed out by a red cross - and when you hover over this cross with the mouse, a message appears stating that there are supposedly no available connections in Windows 7. This behavior of the network comes as a complete surprise to the user. We will teach you how to deal with this problem, but in the meantime, draw your attention to the fact that it often appears immediately after reinstalling the operating system. It may very well be that the cause of the network failure is incorrect installation of drivers or installation of drivers that are not entirely suitable for your adapter model.

In this case, find out the model of your adapter and download the latest drivers for it. To do this, go to the laptop manufacturer’s website - they will probably be found there. Download and install everything that is offered to you. The fact is that in addition to the drivers necessary to ensure the operation of the network, drivers may also be required to support function keys.

Many laptops use function keys like “Fn” to control the adapter. If you do not use these keys, then controlling the adapter becomes a hassle. The so-called flight mode is also activated by the keys. Without installing the appropriate programs, you lose most of the functionality. It's no wonder that the WiFi module begins to behave strangely.

First attempts to fix the problem

To get started, we can suggest trying the following:

Rebooting the router sometimes helps. To reboot, simply unplug the power cord from the outlet and plug it back in.
Call the standard Windows diagnostic tool from the context menu of the connection icon.
Sometimes the WiFi hardware switch on the laptop panel is turned off. Check its condition.
To connect WiFi, you can try to run the service utility supplied by some computer manufacturers along with drivers.
Go to the "Network Connections" section of the control panel. Check if the wireless connection icon is active. If not, activate it from the context menu.
Check the drivers again.

In theory, these events should liven up your network. However, this may not happen. In this case, follow our further recommendations.

Device Manager - to help

Like any computer device, the wireless adapter is registered in a Windows snap-in called “Device Manager”. You can access the dispatcher in different ways:

Right-click on the “My Computer” icon. In the context menu, select “Properties”. In the window that opens, select the “Hardware” tab and click on the “Device Manager” button.
But you can do it differently. Without further ado, call up the “Run” command window and enter devmgmt.msc in the command field – this is the name of the snap-in. The “Run” window itself is called up either by the mouse from the “Start” menu, or by the “Win” + “R” key group.

As a result, a dispatcher window will open, something like the one in the figure:

Go to the "network adapters" node.
Expand this node.
Find in its list a device whose name includes the word “Wireless” - this is the wireless adapter.
Then right-click on its name and select “Delete”.
Then go to the main menu of the dispatcher window.
And in the “Actions” item, click on the “Update hardware configuration” item.

If after this the network remains unavailable, try tinkering with the system services settings.

WLAN Auto Configuration Service

The service in question may also be responsible for the problem. It is located in the same place as all other Windows services, at the address “Control Panel” => “Administration” => “Services”. Find the “WLAN auto-configuration” service in the list and find out whether it is running. To do this, right-click on the service name and select Properties in the context menu that opens. A window similar to the one below will open:

Make sure the Startup Type field is set to Automatic. If this is not the case, then set this parameter, and then restart the service by first clicking on the “Stop” button and then on the “Start” button. Save the changes made by closing the window with the “Ok” button.

If everything is done correctly, the wireless network should become active. If this is not the case, then it is worth looking for other reasons for its inoperability - it may be the equipment itself.

A fairly common problem, especially common after some changes: reinstalling the operating system, replacing a router, updating firmware, etc. Sometimes, finding the cause is quite difficult, even for an experienced technician.

In this short article I would like to dwell on a couple of cases due to which, most often, a laptop does not connect via Wi-Fi. I recommend that you familiarize yourself with them and try to restore the network on your own before turning to outside help. By the way, if it says “without access to the Internet” (and the yellow sign is on), then you better look.

1. Reason No. 1 - incorrect/missing drivers

A very common reason why a laptop does not connect via Wi-Fi. Most often, you will see the following picture (if you look in the lower right corner):

No connections available. The network is crossed out with a red cross.

After all, as it happens: the user downloaded a new Windows OS, burned it to disk, copied all his important data, reinstalled the OS, and installed the drivers that were installed before...

The fact is that drivers that worked in Windows XP may not work in Windows 7, those that worked in Windows 7 may refuse to work in Windows 8.

Therefore, if you are updating the OS, and in general, if Wi-Fi does not work, first of all check whether you have the correct drivers and whether they were downloaded from the official website. And in general, I recommend reinstalling them and watching the laptop’s reaction.

How can I check if the driver is in the system?

Very simple. Go to “my computer”, then right-click anywhere in the window and select “properties” in the pop-up window. Next, on the left, there will be a “device manager” link. By the way, you can open it from the control panel, through the built-in search.

Here we are most interested in the network adapters tab. Look carefully to see if you have a wireless network adapter, as in the picture below (naturally, you will have your own adapter model).

It is also worth paying attention to the fact that there should not be any exclamation marks or red crosses - which indicates problems with the driver, that it may not work correctly. If everything is good, it should be displayed as in the picture above.

Where is the best place to get a driver?

It is best to download it from the manufacturer’s official website. Also, usually the laptop comes with native drivers instead, you can use them too.

Even if you have native drivers installed, but the Wi-Fi network does not work, I recommend trying to reinstall them by downloading them from the official website of the laptop manufacturer.

Important notes when choosing a driver for a laptop

1) Their name, most likely (99.8%), should contain the word “ wireless«.
2) Correctly determine the type of network adapter, there are several of them: Broadcom, Intel, Atheros. Usually, on the manufacturer's website, even for a specific laptop model, there may be several versions of drivers. To know exactly which one you need, use the utility.

The utility perfectly determined what hardware was installed in the laptop. You don’t need to install any settings, you just need to run it.

Several websites of popular manufacturers:

Acer: http://www.acer.ru/ac/ru/RU/content/home

HP: http://www8.hp.com/ru/ru/home.html

Asus: http://www.asus.com/ru/

One more thing! The driver can be found and installed automatically. This is described in the article. I recommend checking it out.

2. Reason #2 - is Wi-Fi turned on?

Very often you have to watch how the user tries to look for the causes of breakdowns where there are none...

Most laptop models have an LED indicator on the case that signals Wi-Fi operation. So, it should burn. To turn it on, there are special functional buttons, the purpose of which is indicated in the product passport.

For example, on Acer laptops, Wi-Fi is turned on using the “Fn+F3” button combination.

You can do it differently.

Go to "control Panel" your Windows OS, then the “network and internet” tab, then “ network and sharing center", and finally - " Change adapter settings«.

Here we are interested in the wireless connection icon. It should not be gray and colorless, as in the picture below. If the wireless network icon is colorless, then right-click on it and click “enable“.

You will immediately notice that even if it does not connect to the Internet, it will become colored (see below). This indicates that the laptop adapter is working and it can connect via Wi-Fi.

3. Reason No. 3 - incorrect settings

It often happens that a laptop cannot connect to the network due to a changed password or router settings. This can happen through no fault of the user. For example, the router settings may be lost if the power is turned off during intensive operation.

1) Checking settings in Windows

First, pay attention to the tray icon. If there is no red cross on it, it means there are available connections and you can try to join them.

We click on the icon and a window should appear in front of us with all the Wi-Fi networks that the laptop has found. Select your network and click “connect”. We will be asked to enter a password, if it is correct, then the laptop should connect via Wi-Fi.

2) Checking the router settings

If you cannot connect to a Wi-Fi network and Windows reports an incorrect password, go to the router settings and change the default settings.

To enter the router settings, go to " http://192.168.1.1/"(Without quotes). Typically, this address is used by default. The default password and login are most often “ admin"(in small letters without quotation marks).

Next, change the settings in accordance with your provider settings and router model (if they are lost). It is difficult to give any advice in this part; there is a more extensive article on creating a local Wi-Fi network at home.

Important! It happens that the router does not connect to the Internet automatically. Go into its settings and check if it is trying to connect, and if not, try connecting to the network manually. This error often happens on TrendNet brand routers (at least it used to be on some models, which I personally encountered).

4. If all else fails...

If you've tried everything and nothing helps...

I will give two pieces of advice that help me personally.

1) From time to time, for reasons unknown to me, the Wi-Fi network disconnects. The symptoms are different each time: sometimes it says no connection, sometimes the icon lights up in the tray as expected, but there is still no network...

A 2-step recipe helps to quickly restore a Wi-Fi network:

1. Disconnect the router’s power supply from the network for 10-15 seconds. Then I turn it on again.

2. I reboot the computer.

After this, oddly enough, the Wi-Fi network, and with it the Internet, work as expected. I don’t know why and why this happens, I don’t want to dig into it either, because... This happens quite rarely. If you can guess why, share it in the comments.

2) There was once such a thing that it was generally not clear how to turn on Wi-Fi - the laptop did not respond to the function keys (Fn + F3) - the LED did not light up, and the tray icon wrote that “there are no available connections” (and it does not find Not one). What to do?

I tried a bunch of methods, I wanted to reinstall the system with all the drivers. But I tried to diagnose the wireless adapter. And guess what - he diagnosed the problem and recommended fixing it by “resetting settings and turning on the network,” which I agreed with. After a few seconds the network started working... I recommend trying it.

That's all. Good luck with your settings...

Technology, especially computer technology, can sometimes behave extremely capriciously and present various surprises. Just yesterday you could use your laptop without any problems, access the Internet using your home wireless connection, receive and send hundreds of files and photos, and use social networks. And today there is no connection to the Internet, and in a place where yesterday there was not a single error in the system tray, a mysterious message is shining: “There are no available connections.” And what to do in such a situation is not entirely clear. We will try to analyze the causes of this problem in as much detail as possible and talk about the most effective ways to solve it.

First, we address those who encountered a similar problem after purchasing a brand new laptop or just reinstalled Windows. If in one of these situations you see a message on your laptop: “No connections available,” then most likely there is a problem with the network driver, which could easily be missing from the system after reinstalling Windows. Another reason in laptops of various models may be a mechanically disabled Wi-Fi adapter. You can learn how to understand which of the two situations was the primary source of the problem in your case from the instructions below.

If a laptop running Windows reported problems with the connection very unexpectedly, and yesterday everything was in perfect order, there may be several more problems, and we will tell you about each of them today.

Any device can experience difficulties in operation and even freeze, similar to how Windows sometimes freezes. Since the router that distributes the Wi-Fi signal is, in fact, the same computer with an operating system and processor, it can also stop working or freeze. At the same time, a working indication on its body can mislead the user and create the appearance of normal operation of the device, but no signal comes from it at this moment.

The display on the device does not always indicate network problems

In order to return the router to normal operating condition, you need to unplug it, wait a few seconds (7-10) and turn it back on. After giving the device a minute to turn on and start all systems, try checking again for available networks on your laptop.

If you receive a Wi-Fi signal directly from your provider, contact support and describe the situation, mentioning that you have no available connections. The operator will be able to remotely reboot his equipment.

The problem is with the network adapter being turned off.

Please note that many modern laptop models running Windows provide a mechanical way to enable and disable the Wi-Fi connection function. This allows you to save battery power. Find the toggle switch at the ends of your laptop case that is responsible for turning on the wireless adapter, and turn it on. If such a toggle switch is not provided, then a special key at the top of the keyboard with an image of a wireless signal can help you. In the case where such a button is not on the keyboard, then the manufacturer has probably provided a certain key combination. Most often this is the Fn function key and the F2 or F3 buttons. You can find out more about this information in the manual for your specific model.

After mechanically turning on the wireless network adapter, try searching for available connections again.

The problem is a software-disabled network adapter

Also, the Wi-Fi adapter in your laptop can be deactivated in Windows itself programmatically. To enable it and repeat attempts to find available networks, you need to launch the Windows Control Panel, go to Network and Sharing Center, and then in the column located on the left side of the open window, click on the “Change adapter settings” link.

You will see information about all the network adapters and connections contained in your laptop. Find "Wireless Connection" and enable it using the right-click menu.

After that, also try to find available Wi-Fi networks using the system tray icon. The problem you are facing may have been resolved and then you will see an available network. But it may well happen that the adapter refuses to turn on, the items in the context menu after right-clicking the mouse turn out to be inactive, or the adapter turns on but still does not see available Wi-Fi networks. In this case, proceed to the next points of our instructions.

The problem is the driver is not working correctly or is missing.

A specialized program is responsible for each function of the Windows operating system. And a system program called a driver is responsible for the operation of each component in your laptop. It is she who corrects the operation of devices, gives them system commands and monitors the correct execution of these same commands. If your system is missing a driver or has a driver version installed that doesn't quite fit your network adapter, you may also experience difficulty finding, connecting to, and transferring networks.

There may be situations in which the driver was installed, configured, and the system worked quite correctly, but after another simple reboot you saw the message “No connections available” and you cannot access the network. Probably, your operating system has a program that is responsible for automatically updating and installing drivers for various devices, and after a reboot, a driver version was installed that does not match the network adapter model, or a test assembly that does not yet work as desired.

To update and install drivers for various components of your laptop, we always recommend using the two most reliable sources - the website of the manufacturer of the computer itself or the website of the manufacturers of its individual components.

Go to the manufacturer's website, download the latest version of the software for the network adapter, making sure first that it is intended for the same version of Windows that is installed on your laptop. After this, install and restart your PC. To avoid problems when installing a new driver, we recommend that you first remove the existing one by finding your network adapter in Windows Device Manager, right-clicking on its name and going to Properties > Driver > Uninstall.

After installing the latest driver and rebooting your PC, search for available networks again to make sure that all systems are working correctly and that you can connect to the network.

The problem is an incorrect system configuration or a violation of registry settings

When all the previous methods have been tried, but none of them have given the desired result, you can resort to a really serious and in-depth search for faults and problems in the system. This is especially recommended for those users who are confident that before the failure, the network adapter performed its functions correctly and you did not interfere with its operation. In this case, the cause could be third-party programs and applications, their installation or removal, or reconfiguration of individual parts of the system. Any of these actions could not have the best effect on the network operation on your laptop, and then you should resort to the following actions.

If you have a backup of your system using specialized software, try restoring the system to the state it was in when the last checkpoint was created. This procedure will undo all recent changes to the system and return it exactly to the state in which your network adapter performed all its functions correctly. Please note that restoring a copy that is too outdated may deprive you of a large number of settings, programs and parameters that have appeared in the system recently.

If you don't have such a backup, use the built-in Windows recovery system, which creates checkpoints during some key procedures performed on the computer. To do this, open “Your Computer Properties” by right-clicking on the “My Computer” icon on the desktop, and then look for “System Protection” in the column on the left in the window that opens. Click the "Restore" button and select the system state point that needs to be restored on your PC.

If system protection was disabled and checkpoints were not created, we recommend running a full OS scan and checking the integrity of Windows files. There is a special service for this that can be started using the command line.

Open a command prompt, manually enter the command sfc /scannow and press Enter on your keyboard. If the system contains damaged files or some parts of the registry are not working correctly, the scanning service will try to detect them and restore them to their original state. This procedure can take quite a long time, and upon completion, a mandatory system reboot will be required.

As a rule, troubleshooting problems with no available connections does not require serious skills and is rarely a reason to contact a service center. You can restore the wireless network adapter using one of the methods given here. If the desired result cannot be achieved using one of the instructions, it may be necessary to combine several methods at the same time. This depends directly on the specific laptop model, its configuration and system parameters.

A fairly common problem among owners of laptops with Windows 7 or Windows 8 (8.1) - at one point in the notification area, instead of the usual wireless Wi-Fi connection icon, a red cross is displayed, and when you hover over it, a message stating that there are no connections available.

Moreover, in most cases, this happens on a completely working laptop - just yesterday, perhaps, you successfully connected to an access point at home, but today this is the situation. The reasons for this behavior may be different, but in general terms, the operating system believes that the Wi-Fi adapter is turned off, and therefore reports that there are no connections available. And now about ways to fix this.

If your wireless network was working and now there are no connections available

If everything worked recently and now you have a problem, try the methods listed below in order. And if these options have already been tried, go to the seventh point, from which we will begin to describe in detail (because everything is not so simple there for novice computer users).

7. Remove the wireless Wi-Fi adapter from Device Manager, install it again

To launch Windows Device Manager, press the Win+R keys on your laptop keyboard and enter the command devmgmt.msc, and then press Ok or Enter.

In Device Manager, open the “Network Adapters” section, right-click on the Wi-Fi adapter, see if there is an “Enable” item there (if there is, turn it on and do not do everything else that is described here, the message “No connections available” should appear) disappear) and if it is not there, select “Delete”.

After the device is removed from the system, in the device manager menu, select “Action” - “Update hardware configuration”. The wireless adapter will be found again, drivers will be installed on it and, perhaps, everything will work.

8. See if the WLAN Auto Configuration service is enabled in Windows

In order to do this, go to the Windows control panel, select “Administration” - “Services”, find “WLAN Auto Configuration” in the list of services and, if you see “Disabled” in its parameters, double-click on it and in the field Set the “Startup Type” to “Automatic” and click the “Run” button.

Just in case, look through the list and if you find additional services that have Wi-Fi or Wireless in their name, turn them on too. And then, preferably, restart your computer.

We hope one of these methods will help you solve the problem when Windows says there are no Wi-Fi connections available.

If your desktop computer or laptop is connected to the Internet, then an unpleasant moment may come when you lose access to the network, and the network connections icon in the notification area will be crossed out with a red cross. When you hover your cursor over it, a message will appear explaining everything. "No connections available". This happens especially often when using a Wi-Fi adapter. Let's find out how to solve a similar problem if you are using a PC with Windows 7.

There are quite a few reasons that can cause the problem we are studying:

Real lack of available networks;
Damage to the Wi-Fi adapter, router or modem;
PC hardware failure (for example, network card failure);
Software glitch;
Lack of current drivers;
Damage to the operating system;
Virus.

We will not talk in detail about such a banal reason as the real lack of accessible networks. This can only be “cured” by returning to the Internet accessibility zone or changing the connection method to one that is valid in the given area. There is also no point in talking too much about hardware faults. They can be eliminated either by a hardware repairman or by replacing a failed part or equipment (Wi-Fi adapter, network card, router, modem, etc.). But we’ll talk in detail about the other reasons and ways to eliminate them.

Method 1: Standard diagnostics

First of all, if you experience the error discussed in this article, follow these simple steps:

Unplug the Wi-Fi adapter from the computer connector and then connect it again;
Reboot the router (it is better to do this by completely disconnecting it from the power supply, that is, you need to remove the plug from the socket);
Make sure you have your Wi-Fi hardware switch turned on if you are using a laptop. It is turned on in different laptop models in different ways: either using a special switch on the case, or using a certain key combination (for example, Fn+F2).

If none of the above helped, then it makes sense to carry out a standard diagnostic procedure.

Unfortunately, this method helps in a fairly limited number of cases. Therefore, if you are unable to resolve the problem when using it, then proceed to the following methods, which are described below.

Method 2: Enable Network Connection

It is likely that the cause of the error may be a disconnected connection in the network connections section "Control Panels". Then you need to activate the corresponding object.

Click "Start" and open "Control Panel".

Go to section "Network and Internet".

Go to "Network Control Center...".

In the left part of the window that appears, click on the inscription "Change adapter settings".

The window that appears shows all the network connections configured on this computer. Find an item that is relevant to you and look at its status. If set to "Disabled", then you need to activate the connection. Right-click on the object ( RMB) and select "Turn on".

After activating the connection, the problem described in this article will most likely be resolved.

Method 3: Removing the adapter from Device Manager

If you connect to the Internet via a Wi-Fi adapter, then one of the ways to solve the problem is to disable it in "Device Manager", and then reactivation.

Go to "Control Panel" by the method that was considered in the description Method 2, and then open the section "System and safety".

Click on the one posted in the group "System" element "Device Manager".

Will start "Device Manager". In the list of equipment types that opens, click on "Network adapters".

In the drop-down list, find the name of the equipment that you use to connect to the Internet. Click on it RMB. Carefully examine the context menu that appears. If it contains a clause "Engage", click on it. This will be enough and you will not need to perform all further actions described in this method. The device was simply turned off, and now you have turned it on.

If the specified item is not present, then this means that the device is likely to malfunction. Therefore, it needs to be temporarily deactivated and then turned on. Click in the context menu "Delete".

A dialog box will open warning you that the device will now be removed from the system. Confirm your actions by clicking "OK".

The procedure for deleting the selected device will be performed.

After that, in the horizontal menu, click "Action", and then from the list that opens, click "Update configuration...".

A search will be made for devices connected using the technology "Plug and Play". The network adapter will be reconnected, and its drivers will be reinstalled.

Next, restart your PC. Perhaps after this the connection availability error will disappear.

Method 4: Reinstalling drivers

One of the reasons for the error we are studying is that incorrect or outdated network adapter drivers are installed in the system. Most often it occurs when connecting the device for the first time or after reinstalling the OS. Then the drivers should be replaced with a current analogue. It is advisable to use exactly those copies that were supplied on a CD or other media along with the device itself. If you do not have such media, you can download the required object from the official website of the adapter manufacturer. Using similar software from other sources does not guarantee a solution to the problem.

Go to "Device Manager", using the same algorithm of actions as in the previous method. Open the section again "Network adapters" and click RMB by the name of the desired device. In the list that appears, select "Update drivers...".

Next, the shell for selecting the update method is activated. Select an option “Search for drivers...”.

In the window that opens, you must specify the media and directory where the drivers will be installed. To do this, click "Review…".

The shell opens "Browse folders". Here you need to indicate the folder or media (for example, CD/DVD) where the drivers supplied with the device or pre-downloaded from the official website are located. After selecting a directory, click "OK".

After the directory address is displayed in the driver search window, you can proceed to install them by clicking the button "Further", but before doing this, make sure that opposite the parameter "Including subfolders" the checkbox has been checked.

The necessary drivers will be installed, and the problem with the lack of Internet connection will probably disappear.

But what to do if for some reason you do not have the driver media that came with the device, and the company’s official website does not work? In this case, there are additional options to install the necessary drivers, although they are recommended to be used only in the most extreme cases, since they do not 100% guarantee interconnection between the OS and the adapter. You can use the following options:

If your Internet does not start at all, then you will have to search and download from another device.

Method 5: Enable the service

If you use Wi-Fi to connect to the Internet, the problem we are investigating may occur due to a service outage "WLAN Auto Configuration". Then it needs to be activated.

Go to the section "Control Panels" entitled "System and safety". This is discussed in the description Method 3. Click on the title "Administration".

In the list of system tools that opens, select "Services".

"Service Manager" can be activated in another way. To do this, dial Win+R and enter in the displayed area:

Then apply button click "OK".

"Service Manager" will be open. To quickly find an element "WLAN AutoConfig Service", arrange all services in alphabetical order by clicking on the column title "Name".

Find the name of the desired service. If the status is not set opposite its name "Works", then in this case it is necessary to activate. Double-click on her name with the left mouse button.

The service properties window opens. If in the field "Startup type" set value "Disabled", then in this case click on it.

A drop-down list will open where you need to select "Automatically". Then click "Apply" And "OK".

After returning to the main interface "Service Manager" select the name "WLAN AutoConfig Service", and on the left side of the shell click "Run".

The service will be activated.

After this, the status will be displayed opposite its name "Works" and the problem with lack of connections will be solved.

Method 6: Checking system files

If none of the above methods help, then there is a possibility that the integrity of the system files has been compromised. In this case, it is necessary to perform an appropriate check and then restore if problems are found.

Click "Start" and select "All programs".

Open the folder "Standard".

Find the element with the name "Command line". Click on it RMB. From the list of action options that appears, choose to run as administrator.

Opens "Command line". Type into its interface:
Then click Enter.

The procedure for scanning the integrity of system elements will be launched. Information about the dynamics of its passage will be displayed right there in the window. "Command line" in percentage terms. While this process is running, you should not close the current window, but you can minimize it. If violations in the structure are detected, a procedure for restoring missing or damaged files will be automatically performed.

If, after completing the scanning procedure, a message appears informing you that recovery is impossible, repeat the entire process again, but this time you will need to start the OS in "Safe Mode" .

Method 7: Eliminate viruses

The cause of the problem of lack of available networks may be a virus infection of the computer. Some malicious programs specifically disable access to the Internet so that the user cannot use external help to remove them, while others simply arbitrarily “kill” or modify system files, which ultimately leads to the same result.

To remove malicious code, there is no point in using a standard antivirus, since it has already missed the threat, which means it will not react to the virus, and may also be infected by this time. Therefore, we recommend using specialized anti-virus utilities that do not require installation. One of the best programs in this class is Dr.Web CureIt. It is best to check from another device or when starting from LiveCD/USB. This is the only way to ensure the maximum likelihood of detecting a threat.

If the antivirus utility detects malicious code, then follow the advice that will be displayed in its interface. There is a possibility that the virus has already damaged system files. Then, after eliminating it, it is necessary to carry out the appropriate check discussed in the description Method 6.

As you can see, the source of the problem with the availability of connections, and therefore with the performance of the Internet, can be a lot of different factors. They can be both external (real lack of network) and internal (various failures), caused by both the software and hardware components of the system. Of course, before fixing a problem, it is recommended to establish its exact root cause, but, unfortunately, this is not always possible. In this case, simply use the methods described in this article, checking each time whether the malfunction is eliminated or not.
