Writes no networks available. No WiFi connections available on Windows

Hello Kirill!

Lack of drivers

• If you see that a red cross appears on the WI-FI icon (ladder) or on the monitor icon, this may indicate problems with the network adapter driver. Very often, especially after reinstalling the system, specialists forget to install this driver because it is rarely included in the Windows build. This can be solved on your own.
• All you need is to find the driver disk for your laptop. If this is not available, then you can download it from the official website of your PC manufacturer. It is very important: it is from the official site, because in other places virus-infected files may come across.
• Install the resulting driver and reboot the hardware.

After the done manipulations, you need to check the result. This can be done in Device Manager. If there, in the list of network devices, you see your WI-FI adapter, then everything went well and you can connect to the network.

Receiver Activity Check

Often modern models laptops are equipped with a toggle switch to turn on the WI-FI card. There are many cases when the user himself or his relatives turn off this switch, which leads to a lack of network.

You can find out if this toggle switch is active by the presence of an LED on the laptop case. Its location depends on the model and manufacturer.

If the LED is on or blinking, then you need to navigate by its color:

• yellow - disabled;
• white, green - included.

If your model does not have an indicator, there is another option:

• go to "Start";
• then - in the "Control Panel;
• find the item "Network and Internet", and in it "Network and Sharing Center";
• click on "Change adapter settings";
• then right click mouse click on the label "Wireless Network Connection";
• select "Enable".

If after that the color of the label has changed, then you did everything right.

Problem in settings

Quite often it happens that the wireless network settings in a laptop get lost due to failures or the settings in the router “fly off”.

The consequence of such processes is a ladder icon with a yellow blot, i.e. there are available networks, you just need to enter data to connect. You need to click on this icon, select desired network and enter the password in the field.

To check the status of the settings on your wireless WI-FI router(if it exists), you need:

• in browser type in address bar ip address: 192.168.0.1 or 192.168.1.1;
• in the authorization window, enter the login admin, password admin or 1234 or leave this field empty;
• make changes to the settings of the wireless mode and WAN mode, in accordance with the standards of your provider and save them.

If after that nothing has changed, then you can do the following steps:

• remove the wireless adapter from the device manager and restart the PC;
• Check if the WI-FI Auto Configuration service is enabled. In order to do this, go to the Windows control panel, select "Administrative Tools" - "Services", find "WLAN Autoconfiguration" in the list of services and, if you see "Disabled" in its parameters, double-click on it and in the field " Startup type" set to "Automatic", and also click the "Start" button.
• check on the router in the security settings which mode is selected b / g / n. There may be a mismatch between the router mode and the laptop.

That's all. I hope some of the tips help you.

Sincerely, Evgeny.

The misunderstanding, which we will touch upon in our note, is increasingly troubling users of laptops included in wireless network. This misunderstanding is of a technical nature - the essence of the problem is the unexpected failure of the built-in or external router receive and transmit data.

At the same time, the network icon in the tray takes on a characteristic look - a ladder crossed out with a red cross - and when you hover over this cross with the mouse, a message appears stating that supposedly there are no connections available in the Windows 7 system. This network behavior turns out to be a complete surprise to the user. We will teach you how to deal with this problem, but for now, drawing 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 the incorrect installation of drivers or the installation of drivers that are not quite 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 website of the laptop manufacturer - there they will certainly be found. Download and install everything that will be offered to you. The fact is that in addition to the drivers necessary to ensure the network, drivers may also be required to support the function keys.

Many laptops use function keys such as "Fn" to control the adapter. If you do not use these keys, then managing the adapter turns into a hassle. The so-called flight mode is also activated by the keys. By not installing the appropriate programs, you lose most of the functionality. No wonder the WiFi module starts behaving strangely.

First attempts to fix the problem

To get started, you might want to try the following:

• Rebooting the router can sometimes help. To reboot, simply unplug the power cord and plug it in again.
• 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 to WiFi, you can try to run the service utility supplied by some computer manufacturers along with the drivers.
• Go to the Network Connections section of the control panel. Check if the icon is active wireless connection. If not, activate it from the context menu.
• Check your drivers again.

In theory, these events should bring your grid to life. However, this may not happen. In this case, follow our further recommendations.

Device manager help

Like any computer device, the wireless adapter is registered with Windows snap-in named "Device Manager". There are several ways to access the dispatcher:

• Right-click on the "My Computer" icon. V context menu select "Properties". In the window that opens, select the "Hardware" tab and click on the "Device Manager" button.
• And you can do otherwise. 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 either with the mouse from the "Start" menu, or with the "Win" + "R" key group.

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

• Navigate 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 item "Actions" click on the item "Update hardware configuration".

If after that the network is unavailable, try digging into the settings of the system services.

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" => "Administrative Tools" => "Services". Find the "WLAN autoconfig" service in the list and find out if it is running. To do this, right-click the service name and select properties from 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 option, and then restart the service by first clicking on the "Stop" button, and then on the "Start" button. Save your changes by closing the window by clicking the OK button.

If everything is done correctly, then 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 case in the equipment itself.

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

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

If a laptop running Windows reported connection problems unexpectedly, and everything was fine yesterday, 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 like Windows sometimes freezes. Since the router that distributes the Wi-Fi signal is, in fact, the same computer with an operating system and a processor, it can also stop working or freeze. At the same time, a working indication on its case can mislead the user and create the appearance of normal operation of the device, but no signal comes from it at this moment.

The indication on the device does not always report network problems

In order to return the router to its normal working state, you need to unplug it, wait a few seconds (7–10) and plug it back in. After giving the device a minute to turn on and start all systems, try again to check for available networks in your laptop.

If you receive a Wi-Fi signal directly from the provider, contact support and describe the situation, mentioning that you do not have available connections. The operator will be able to remotely reboot his equipment.

The problem is the disabled network adapter

Please note that many models of modern laptops running Windows provide for mechanical enabling and disabling of the Wi-Fi connection function. This saves battery power. Find the toggle switch on the ends of your laptop case that is responsible for turning on 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 the image of a wireless signal can help you. In the event that there is no such button on the keyboard, then, probably, the manufacturer has provided a certain key combination. Most often, this is the Fn function key and the F2 or F3 buttons. You can check this information in the manual for specific model.

After such a mechanical activation of the wireless network adapter, try again to search for available connections.

The problem is in the software disabled network adapter

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

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

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

The problem is the incorrect operation of the driver or its absence

A specialized program is responsible for the operation of each function of the Windows operating system. And for the operation of each component in your laptop, a system program is responsible, called a driver. 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 version installed that does not exactly match this network adapter, you may also experience difficulty finding networks, connecting them, and transferring data.

There are 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 can’t go online. It is likely that your operating system has a program that is responsible for automatically updating and installing drivers. various devices, and after a reboot, a driver version was installed that does not match the model of the network adapter, or a test build that does not yet work as expected.

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 network adapter software, making sure that it is for the same version of Windows that is installed on your laptop. After that, 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 the Windows Device Manager, right-clicking on its name and going to Properties> Driver> Uninstall.

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

The problem is an incorrect system configuration or registry violation

When all the previous methods have been tried, but none of them have given the desired result, you can resort to really serious and deep troubleshooting and system problems. This is especially recommended for those users who are sure that until the moment of 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, reconfiguration of individual parts of the system. Any of these actions could not have the best effect on the network in your laptop, and then you should resort to the following steps.

If you have backup copy of your system created using specialized software, try restoring the system to the state it was in at the time the last checkpoint was created. This procedure will cancel all last changes in 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 old may cost you a large number settings, programs and parameters that have appeared in the system recently.

A fairly common problem, especially common after some changes: reinstalling the operating system, replacing the router, updating firmware, etc. Sometimes, finding the cause is not easy enough, even for an experienced master.

In this short article, I would like to dwell on a couple of cases due to which, most often, the 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 #1 - Wrong/Missing Driver

A very common reason why a laptop does not connect via Wi-Fi. Most often, the following picture appears before you (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 used to be ...

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 indeed, if Wi-Fi does not work, first of all check whether you have the drivers, whether they were downloaded from the official site. Anyway, I recommend reinstalling them and watching the reaction of the laptop.

How to check if there is a driver in the system?

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

Here we are most interested in the tab with network adapters. Look carefully if you have a wireless network adapter, as in the picture below (of course, 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 fine - 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 official website of the manufacturer. Also, usually, instead of with a laptop, native drivers come, you can use them.

Even if you have native drivers installed and 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 laptop driver

1) In their name, most likely (99.8%), there should be 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 in 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 equipment is installed in the laptop. You don't need to install any settings, just run it.

H several sites of popular manufacturers:

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

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

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

One more thing! The driver can be found and installed automatically. This is described in the article. I recommend to take a look.

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 must be on fire. To enable it, there are special function buttons, the purpose of which is indicated in the passport for the product.

For example, on Acer laptops, Wi-Fi is enabled by pressing the Fn + F3 buttons.

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 join the Internet, it will become colored (see below). This signals that the laptop adapter has worked and it can connect via Wi-Fi.

3. Reason #3 - Incorrect Settings

It often happens that the 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 when the power is turned off during its intensive work.

1) Checking settings in Windows

First, pay attention to the tray icon. If there is no red cross on it, then 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 it is impossible to connect to the Wi-Fi network, and Windows reports an incorrect password, go to the router settings and change the default settings.

In order to enter the settings of the router, go to " http://192.168.1.1/" (No quotes). Usually, this address is used by default. The default password and login, most often, " admin" (in small letters without quotes).

Next, change the settings in accordance with your provider settings and router model (if they go wrong). It is difficult to give any advice in this part, a more extensive article on creating local network WiFi at home.

Important! It happens that the router does not connect to the Internet automatically. Go to 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 tips that help me personally.

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

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

1. I disconnect the power supply of the router from the network for 10-15 seconds. Then I turn it on again.

2. I restart the computer.

After that, oddly enough, the Wi-Fi network, and with it the Internet, work as expected. Why and because of what this is happening - I don’t know, I don’t want to dig either, somehow. this happens quite rarely. If you know why, please share in the comments.

2) It was once that it was not at all clear how to turn on Wi-Fi - the laptop does not respond to the function keys (Fn + F3) - the LED is off, and the tray icon says that “there are no connections available” (moreover, it does not find Not one). What to do?

I tried a bunch of ways, I already wanted to reinstall the system with all the drivers. But I tried to diagnose the wireless adapter. And what would you think - he diagnosed the problem and recommended to fix it "reset settings and turn on the network", which I agreed with. After a few seconds, the network started working ... I recommend trying it.

That's all. Happy settings...

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

At the same time, in most cases, this happens on a completely working laptop - yesterday, you may have successfully connected to an access point at home on it, and today this is the situation. The reasons for this behavior may vary, but in general terms - operating system considers that the Wi-Fi adapter is turned off, and therefore reports that there are no available connections. And now for ways to fix it.

If the wireless network was working, but now there are no available connections

If everything was working recently, and now there is a problem, try the methods listed below in order. And if these options have already been tested, 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 start the dispatcher Windows devices, press the Win + R keys on the laptop keyboard and enter the command devmgmt.msc, and then press Ok or Enter.

In Device Manager, open the " Network adapters”, right-click on the Wi-Fi adapter, pay attention to whether the “Enable” item is there (if there is, turn it on and do not do everything else that is described here, the inscription there are no connections available should disappear) and if it is not there, select item "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 AutoConfig" service is enabled in Windows

In order to do this, go to the Windows control panel, select "Administration" - "Services", find "WLAN Autoconfiguration" in the list of services and, if you see "Disabled" in its parameters, double-click on it and in the field "Startup type" set to "Automatic", and also click the "Start" 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 writes that there are no available WiFi connections.

If on a laptop after pen Windows installation or just without any visible reasons Wi-Fi does not work, writes that there are no available connections and shows a red cross on the connection icon, the material below describes several possible causes this problem and what to do to fix it.

About other problems with Wi-Fi connection: ,

No Wi-Fi connections available when laptop is turned on again

If you have previously connected to wireless networks on the same laptop WiFi networks, and now, without any action with the drivers, without reinstalling Windows, you suddenly write that there are no connections available, this usually means that for some reason the Wi-Fi adapter turned off.

Here's what to look out for in order to try and fix the problem:

In general, this is usually possible options, which help fix the problem if it is not missing drivers, a recently reinstalled system, or some kind of hardware problem. If these options do not help, you can try the following solutions.

Just in case, also check if the Wi-Fi adapter was somehow accidentally disabled in Device Manager:

1. Press the Win+R keys on your keyboard, type devmgmt.msc and press Enter.
2. See if Wi-Fi is present in the "Network adapters" section (May contain the words "Wireless" or "Wi-Fi" in the name. Right-click on it and if there is an "Enable" item in the menu, click it (and if no, it's already enabled).

Wi-Fi not working on laptop after installing Windows 10, 8 or Windows 7

If the “no connections available” problem occurred to you after installing or reinstalling Windows (or you just never tried to connect to Wi-Fi from this laptop, which is almost the same), then it is almost guaranteed that the problem is in the drivers, moreover, I’m sure if you have already been looking for what to do if Wi-Fi does not work, then you have seen this reason mentioned, but few people mention that the matter may be not only in drivers, not only for Wi-Fi, which will also be discussed.

So, the most important thing you should consider about Wi-Fi drivers:

1. Wi-Fi drivers for a laptop should be installed from the official website of the laptop manufacturer (the drivers are located there in the “support” section, as a rule) specifically for your model. If, for example, there are no drivers for Windows 10, you can install for 8 or 7. If they are not installed, try installing in compatibility mode.
2. If in Device Manager for WiFi adapter it says "The device is working fine" and the driver doesn't need to be updated - that doesn't mean anything (i.e. the device may actually be working abnormally and the driver needs to be updated). We still install the official driver.

The most important. And now a subtle nuance regarding the operation of Wi-Fi on a laptop after reinstalling the system: if, before reinstalling the OS on a laptop (on many models), turn off the wireless network with a key on the keyboard (or Fn + key), then after installation, even with the original wireless drivers adapter, you will see a message stating that there are no connections available and a red cross on the connection icon - because the adapter is disabled from the point of view of Windows. And sometimes the same thing happens without first turning off Wi-Fi.

At the same time, just the drivers and utilities for the operation of these keys are what many do not install, and they are not in the driver packs.

It's easy to check if you have it installed - try using any of the function keys from the top row (except for sound and brightness - they can work like that). If they do not work, it is quite possible that the reason for the not working Wi-Fi is this.

The solution is to install all the necessary official utilities for your laptop model so that the function keys in top row earned on the laptop keyboard. And then turn on the adapter with the keys. Moreover, in some cases this is not the only utility, but immediately a set of drivers and utilities from the manufacturer, therefore the best option is to install all official drivers from your laptop's support page.

As a rule, such official utilities are named in the spirit: Hotkey Utility (Asus and Acer), Keyboard Driver, Launch Manager (Acer), Hotkey Features Integration (Lenovo) and the like.

Which, in turn, may require additional official utilities, such as, for example, HP Unified Extensible Firmware Interface (UEFI) Support Environment and HP Software Framework for HP laptops (plus, some of them may additionally require an HP Wireless Button Driver for turning on Wi-Fi), and for laptops Lenovo drivers these keys are a whole package that includes the System Interface Driver and other software.

So, in order, we install the official drivers until the function keys work (at the same time, the option that required drivers/utilities are only for previous versions The OS that was originally installed on the laptop is very common, please note and try to install them), and after that we try to turn on Wi-Fi on the laptop.

If your desktop computer or the laptop is connected to the Internet, then such 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. Hovering over it will display a message 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 Windows 7 PC.

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

• The real lack of available networks;
• Failure of a Wi-Fi adapter, router or modem;
• PC hardware failure (for example, failure of network card);
• Software failure;
• Lack of up-to-date drivers;
• Damage to the operating system;
• Virus.

We will not talk in detail about such a banal reason as the real lack of available networks. This is “treated” only by returning to the Internet accessibility zone or changing the connection method to the one that operates in the area. It also makes no sense to talk a lot about hardware malfunctions. They are eliminated either by a hardware repairman or by replacing a failed part or equipment (Wi-Fi adapter, network card, router, modem, etc.). But we will just talk about the other causes and how to eliminate them in detail.

Method 1: Standard Diagnostics

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

• Pull out the Wi-Fi adapter from the computer, and then plug it back in;
• Reboot the router (it is better to do this by completely de-energizing it, that is, you need to pull the plug out of the socket);
• Make sure you have the Wi-Fi hardware switch enabled if you are using a laptop. It turns on at different models laptops different ways: either by using a special switch on the case, or by using a specific key combination (for example, Fn+F2).

If none of the above helped, then it makes sense to standard procedure diagnostics.

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

Method 2: Turn on the network connection

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

1. Click "Start" and open "Control Panel".



2. Skip to section "Network and Internet".



3. Go to "Network Control Center...".



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



5. The window that appears shows all the settings configured for this computer network connections. Find an object that is relevant to you and take a look at its status. If set to "Disabled", you need to activate the connection. Click on the object with the right mouse button ( PKM) and select "Turn on".



6. After the connection is activated, the problem described in this article is likely to be resolved.

Method 3: Remove the adapter from Device Manager

If you connect to the Internet through a Wi-Fi adapter, then one of the ways to solve the problem is to turn it off in "Device Manager" and then reactivate.

1. Go to "Control Panel" the method discussed in the description Method 2 and then open the section "System and safety".



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



3. will start "Device Manager". In the opened list of equipment types, click on "Network Adapters".



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

   

   If there is no specified item, then this means the probability incorrect operation devices. Therefore, it must be temporarily deactivated, and then enabled. Click in the context menu "Delete".



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



6. The procedure for deleting the selected device will be performed.



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



8. It will search for devices connected using the technology "Plug and Play". The network adapter will be reconnected and the drivers for it will be reinstalled.



9. Next, restart your PC. Perhaps after that the error with the availability of connections 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 on the system. Most often, it occurs when you first connect the device or after reinstalling the OS. Then the drivers should be replaced with the current analogue. It is advisable to use exactly those copies that were supplied on a CD-ROM or other media along with the device itself. If you do not have such media, you can download the desired object from the official website of the adapter manufacturer. Using similar software from other sources does not guarantee a solution to the problem.

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



2. Next, the shell for choosing the update method is activated. Choose an option "Search for drivers...".



3. In the window that opens, you must specify the media and directory for the location of the drivers to be installed. To do this, click "Overview…".



4. The shell opens "Browse folders". Here you need to specify the folder or media (for example, a CD / DVD-ROM) where the drivers supplied with the device or pre-loaded from the official site are located. After selecting a directory, press OK.



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

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

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

Method 5: Enable the service

If you are using Wi-Fi to connect to the Internet, the problem we are investigating may be due to a disconnection of the service "WLAN auto-configuration". Then it needs to be activated.

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



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

   

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

   Then apply click on the button OK.



3. "Service Manager" will be open. To find an element faster "WLAN AutoConfig Service", build all services in alphabetical order by clicking on the column name "Name".

8. The service will be activated.



9. After that, the status will be displayed opposite its name. "Working" and the problem with the lack of connections will be solved.

Method 6: System File Checker

If none of specified methods did not help, that is, it is likely that the integrity of system files was violated. In this case, it is necessary to perform an appropriate check with subsequent recovery in case of problems.

1. click "Start" and choose "All programs".



2. Open folder "Standard".



3. Find the element with the name "Command line". Make a click on it PKM. From the list of options that appears, stop on running as administrator.



4. opens "Command line". Type into its interface:

   Then click Enter.



5. Integrity scan procedure system elements will be launched. Information about the dynamics of its passage will be displayed immediately in the window « command line» in percentage terms. During the execution of the specified process, you should not close the current window, but you can minimize it. If violations in the structure are detected, the procedure for restoring missing or damaged files will be automatically performed.



6. If, after the scanning procedure is completed, 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 reason for the problem of the lack of available networks may be infection of the computer with a virus. Some malware they specifically disable Internet access so that the user cannot use external help to remove them, while others simply arbitrarily “kill” or modify system files, which leads to the same result.

To remove malicious code, it makes no sense to use regular antivirus, since he has already missed the threat, which means that he 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 of this class is Dr.Web CureIt . It is best to check from another device or when starting from a LiveCD/USB. Only in this way can you ensure the maximum probability of detecting a threat.

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

As you can see, the source of the problem with the availability of connections, and hence with the performance of the Internet, can be a lot of different factors. They can be both external (real lack of a network) and internal (various failures), be caused by both software and hardware components of the system. Of course, before fixing the 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, each time checking whether the malfunction has been eliminated or not.
