Why is Wi-Fi not visible? The laptop does not see the Wi-Fi network and does not connect to Wi-Fi

Youtube

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 icon wireless Wi-Fi connection, a red cross is displayed, and when you hover over it, a message stating that there is no connection.

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 vary, but general outline- the operating system believes that the Wi-Fi adapter is turned off, and therefore reports that it is not available connections. 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 name or Wireless, 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.

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 failure of the built-in or external router 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 for now let us draw your attention to the fact that it often appears immediately after reinstallation operating system. It may very well be that the cause of the network failure is incorrect installation drivers or installing drivers that are not entirely suitable for your adapter model.

In this case, find out the model of your adapter and download the most suitable ones for it. fresh drivers. 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 standard tool Windows Diagnostics from the context menu of the connection icon.
Sometimes the WiFi hardware switch on the laptop panel is turned off. Check its condition.
To do this, 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 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:

Click right click mouse over the “My Computer” icon. IN 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.

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, use social media. 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 her decisions.

First we turn to those who have encountered similar problem after buying a brand new laptop or just reinstalling Windows. If in one of these situations you see the message: “No connections available” on your laptop, then most likely there is a problem with network driver, which could easily be missing from the system after reinstalling Windows. Another reason in laptops various models The Wi-Fi adapter may be mechanically disabled. 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 normal operation 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 working condition, 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 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 it may help you special key at the top of the keyboard with a picture of a wireless signal. 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 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 turn it on and try again to find available networks you need to launch the Panel Windows management, go to Network and Sharing Center, and then in the column located on the left side open window, follow the link “Change adapter settings”.

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 will be inactive, or the adapter has turned 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.

Each function of the Windows operating system is responsible for its operation. specialized program. And it is responsible for the operation of each component in your laptop system program, which is called the 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 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. Your operating system probably has a program that is responsible for automatically updating and installing drivers various devices, and after a reboot, a driver version was installed that did not match the network adapter model, or a test assembly that did not yet work as desired.

To update and install drivers various components for 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 the Manager Windows devices by right-clicking on its name and going to Properties > Driver > Uninstall.

After installing the latest driver and rebooting your PC, scan for available networks again to make sure correct operation all systems and for connecting 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 something really serious and deep search malfunctions and system malfunctions. 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, reconfiguration individual parts systems. Any of these actions may not be the most in the best possible way affect 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 cancel everything last changes in the system and will 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 deprive you of large quantity settings, programs and parameters that have appeared in the system recently.

If such backup copy you don't have it, refer to the embedded system Windows recovery, which creates control points during some key procedures performed with 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 resorting to a full OS scan and integrity check Windows files. There is a special service for this that can be started using the command line.

Open command line, manually enter in it sfc team/scannow and click on keyboard Enter. 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 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.

Quite often, many users of computers running the seventh and eighth Windows versions It may happen that a cross appears instead of the usual wireless connection icon, indicating that there are no connections available.

Moreover, this happens mainly on a fully working computer. At the same time, up to
At that moment everything was working fine and it was possible to connect to the Internet, but now there is no such option. This problem may occur due to various reasons, however, it all comes down to the fact that the operating system does not see the Wi-Fi module and considers it turned off, as a result of which it displays a message about the absence of connections. But this problem can be fixed. There are several methods for this.

If Wi-Fi has not been used on this laptop before, or Windows has been reinstalled

If a wireless connection has never been used on a laptop, and now a Wi-Fi router has appeared and you need to connect to it, but this problem arises, then you need to search the Internet for advice on why Wi-Fi does not work on a laptop.

The main thing that needs to be done in this case is to install all the necessary drivers, which need to be downloaded from the manufacturer’s official resource, but not the driver pack. At the same time, it is necessary to download drivers not only for the Wi-Fi module, but also to maintain the functionality of the laptop keys, which are designed to turn on wireless adapter.

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

If everything was working fine up to this point, and then suddenly a problem appeared. this problem, then you need to check all the methods described below in turn. You can try disconnecting the router from electrical network, and then turn it on again. In addition, it is worth trying to use the “Troubleshooting” section, which appears when you click on the Wi-Fi connection icon with a cross.

In addition, you need to check whether Wi-Fi is turned on on the laptop, if it has one, and whether you can turn it on using the function keys. It is also worth visiting a proprietary Wi-Fi network management program, if available. In addition, you need to make sure that the wireless connection is in the list of connections.

In the “eight”, in addition to all the methods described, you should go to the “Control Panel” and select “Options”. In this section, you need to click on “Change PC settings”, and then select “Network” or “Wireless”, depending on the version. Here you need to check that all modules are active. In 8.1 you need to check if
Is Airplane Mode enabled?

In addition, it is worth visiting official resource laptop manufacturer and download drivers for the Wi-Fi module from it and install them. It's worth doing, even if you already have such drivers, it's still worth trying.

If after doing all this, nothing has changed, then you can try another method. It is not the simplest, so for inexperienced users it will not be so easy to complete.

Remove the wireless Wi-Fi module from the device manager and install it again

To open the device manager, you need to press Win+R and enter the command devmgmt.msc, after which you need to click OK. Then you need to go to “Network adapters”. Here you need to right-click on the Wi-Fi module. It is worth checking that there is no “Enable” item in the context menu. If there is one, then you need to use it and not perform the steps described below. If this is not the case, then you need to select “Delete”.

After removing the device from the operating system, in the device manager you need to select “Action” and click “Update hardware configuration”. This will start searching for a Wi-Fi module, after which all necessary drivers. Perhaps after this everything will start working.

See if the WLAN AutoConfig service is enabled in Windows

To perform this method, you need to go to the “Control Panel”. In this section you need to select “Administration”. After this, you need to click on “Services”. In this section you need to find the “WLAN Auto Configuration” service. If it says “Disabled”, then you need to double-click on it and in the “Startup type” line set it to “Automatic”. After this, you need to click “Run”.

These are all ways to solve problems with Wi-Fi connection. Surely one of them can help. They are all pretty simple. In addition, among them there are those that even novice users can use without harming the computer.

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...

Wifi is very convenient way Internet connection. But situations arise when the laptop does not see home network and there are no connections available. This is due to a number of unrelated problems. Why doesn't my laptop see the wifi network? Let's look at this issue more carefully.

What to do if the laptop does not see wifi? Before we start troubleshooting the device, let’s check the functionality of the home network. This is necessary to understand the cause of the malfunction.

Let's talk about the router. Sometimes network problems occur due to this equipment freezing. If you see that the lights on it are blinking in a non-standard mode, then you need to fix it. To do this, unplug the router from the outlet, wait a few minutes and start it up again. If there were no serious problems or breakdowns, then this will solve the problem. After this, the laptop will be able to connect to the network.

If your router freezes, it doesn't mean it's not working.

This is the most incomprehensible problem of all that exists in it. In any case, if there is no connection, it must be rebooted.

If you live in an area with unstable power supply, this may also affect your router. Its settings are due to constant change the tension may be relieved, and it will stop distributing Wi-Fi. In such cases, you need to go to the device’s web interface. To do this, launch the browser and enter address bar ip, which is indicated on back side router. The password and login are indicated there.

Checking the functionality of the laptop

If checking the router does not show any faults, then you need to check the laptop itself. First of all, we examine the work network equipment. All modern models Laptops have light bulbs that are located below the keyboard. We must find the one next to which there is a sign of an antenna or something else associated with a wireless network. If this light is not on, then press the “fn” button (available in every laptop) + f8 or another key that suits your model. If it burns, then you don’t need to do anything.

We also check the connection settings themselves. The network name, if it is not accessible to all devices, and the password for it must be entered correctly.

Before you panic, you just need to restart your laptop. In some cases this will help.

More reasons why a laptop does not see wifi

If The laptop does not see the wifi network, then in addition to all the others, there are obvious points that we forget about. So, your device may not see the wifi network due to simple reasons. Let's look at them and answer the question of what to do with them:

Router turned off. Turn it on and the problem should be solved.
If you are far from the router, then you need to move closer to it or set up a wifi repeater.
If the router freezes, then simply reboot it.
Switched off wifi adapter on a laptop. We turn it on, and a special light should light up.

All these problems can be solved very quickly and require virtually no special knowledge. Now let's move on to more complex reasons for which the laptop does not see the Wi-Fi network:

Unconfigured router. Exists optimal settings for each model of this device. If you are unable to set it up yourself, then you should contact your provider, who will do it with a guarantee and with the highest quality.
If not every device finds the wifi network. What to do? In such cases, you need to go into the router settings and change the “visibility” item.
Damage to the wifi receiver. A laptop is a technically complex device that should not be disassembled on your own. If it's broken home wifi receiver, you can’t do it without the help of professionals. Replacing the receiver can cost you quite a bit of money.
Lack of drivers. This usually happens after reinstalling the operating system. To solve this problem, you need to go to the website of the manufacturer of your device, where you will find all the necessary drivers. You can also download driver packs that will update ALL drivers for your laptop. If this is not the reason, then such updates will never harm your device.
Viruses and other malicious software. They can block wifi networks and other methods of connecting to the Internet. You can get rid of them using antivirus programs such as Kaspersky antivirus, avira or microsoft security essentials In some cases best option- reinstalling the operating system, because from large number Viruses that have accumulated for a long time are very difficult to get rid of.
Windows related problems. They arise mainly due to pirated copies and incomprehensible assemblies found on the Internet. You must use licensed software.
Wrong MAC address. It is unique for each device and is indicated on the back of the router. But some Internet providers are changing it. If you don't know new MAC address, then call your provider. He will tell you how to use it to normalize access to Wi-Fi.

What to do about the above problems? There is a small solution for each of them, but if you are not confident in your ability to do them, then it is better to contact a professional.

So, a couple of months ago I encountered a common household problem. Laptop ( Windows 7) sees a lot different wi-fi points, but does not see the required wi-fi point(the one to which he needs to connect), and all the other computers have established a perfect connection and have been downloading porn from the Internet for a long time.

After googling on the Internet, I found a very trivial solution: changed channel Wi-fi points (in the access point settings).

I guess this is happening because lately wi-fi There are points in almost every apartment, and many of them have self-determination of the range. It works as follows: the point turns on and scans everything around, determines which channels are occupied and selects the one that is not busy, but due to the fact that your computer is located at a distance from it, it may well catch the signal that your point didn't catch it. You turn on your computer, it also scans everything around and is the first to catch a signal from the point that your point overlooked. And in the end the computer doesn’t see desired point — she works with another on the same channel.

Quite recently, I again encountered this problem, but this time I did not have access to the point, and I really wanted to go to the Internet (the only entertainment I had at home was persimmons and the book “Western Philosophy from the Origins to the Present Day”). So I decided to try setting up wi-fi from the computer side.

In the adapter settings changed the parameter "Scan valid interval for minimum value» and everything worked (control panel → network control center and shared access→ network and sharing management → management wireless networks→ adapter properties → configure → advanced).

This parameter is responsible for the broadcast scanning interval to search for new wi-fi connections . In my case, up to this point, the connection to the point had already been established; the checkbox was selected in the settings"Connect automatically, if the network is within range" (control panel → network and sharing center → manage networks and sharing → manage wireless networks ( « Properties» right-click on the connection you need)). Accordingly, scanning the airwaves every 20 seconds gives a greater chance that the computer will see the desired point and immediately establish a connection with it. This is what happened.

And a little about other options:

AdHoc 11 n . You can read what it is.

Transmit buffer, receive buffer (Transmit buffer, Receive buffer). Meaning this parameter allows you to specify the size of the buffer that stores data packets received from the network. On the Internet, in various forums, it is advised to set these values to the maximum, unless of course you have weak computer(in this case, I would advise buying a new one).

Preamble 802.11 b (Preamble 802.11 b). A sequence of binary bits that help synchronize receivers and prepare to receive transmitted data. I am connecting to an access point with 802.11 radio type n , so I set this value to “Only long" ( Long Only ) . If you will have some problems in this mode, then you will bark default value.

Network address. MAC -address of the configured interface software. Manufacturers themselves set this value as unique, but if you are hiding from someone, you can change it.

And further. On the tab"Power Management" I unchecked “Allow this device to turn off to save power” , anyway, the battery on the laptop died a long time ago.

I am glad to welcome you, dear visitors, to the website! In today's article we will take a closer look at what to do if your laptop does not see the wi-fi network. Today, a wi-fi network can be found very often, especially in big cities.

In restaurants, pubs, bars, cinemas, stations Maintenance etc. This list can be continued endlessly, besides, the lion's share is also distributed through a wi-fi router.

The laptop does not find the WiFi network.

If the router whose network you cannot connect to belongs to you, try using the instructions

But what to do if you are sure that wi fi is definitely there and you even see it on another device (smartphone, tablet, etc.), but your laptop or netbook does not find a single wi fi network? Let's take a closer look at this problem.

After all, in reality there are not so many reasons. It is enough just to check each of them one by one. For some, there must be access to a router.

1. Check available networks in your radius.

By the way, if we talk about the range of a wi-fi router, here we can note distances from 10 m (in an apartment or house) to tens of kilometers (in open areas without obstacles and on an industrial scale).

Among the factors that affect the range of a wi-fi network are data transmission protocols (802.11a, 802.11b, 802.11g and 802.11n), room walls, tree foliage (due to water content, which has a dampening effect on wi-fi) , included microwave (also uses microwave frequencies), other wi-fi networks.

If you know other factors that affect signal attenuation, write about them in the comments.

To increase the range of the Wi-Fi network, you can use intermediate devices. But this is closer to industrial use.

If you have access to the router, then it would not be superfluous to reboot it by simply turning off and on the power.

2. Is Wi-Fi turned on on your laptop?

In order to turn it on, you just need to press the power button or the key combination (fn+F1-F12) to turn on wi fi, depending on your laptop model.

Then click on the “Connections” icon next to the clock. Select "Change adapter settings" and check that "Wireless network connection" was active (right-click → "enable").

3. Check if wi-fi is turned on on the router?

Everything is clear here - the network and power cables are connected. The router should show signs of life (there is a light indication).

If there is no indication, the problem is in the wires, the socket or the router itself.

4. The driver is not installed or is out of date.

Another reason why a laptop adapter may not see wi fi is the lack of a corresponding driver on the laptop.

To check the version, open Device Manager (right-click on My Computer → Manage). In the window that opens, select “Device Manager” → “Network Adapters”. Here, in addition to network connection, there should be a similar entry:

If it is not there, you need to download and install the required driver.

If the device is still displayed in " Network adapters", right-click on it and select "Properties". And in the new window, in the “Driver” tab, pay attention to the “Development date” item.

If the difference with current date essential, you need to update this driver from the official website of the developer.

5. Service center.

If you do not experience any of the above breakdowns, then it makes sense to contact a specialized service center. Perhaps the problem is with your router (if the laptop sees other networks) or the laptop itself (if it does not display any networks, but you are sure of their presence).

Why doesn't my laptop see Wi-Fi? There are access points almost everywhere. But there is no way to connect to the Internet. Because the laptop seems to be “blind”. Everything seems to be done correctly.

Completed necessary settings. And the computer is deaf. Why?

The laptop does not detect wireless Internet: why?

Many people have encountered a similar problem. The most annoying thing is that the failure could happen at any site, at any link. The popular routers that people use to connect today are configured in approximately the same way. On the laptop side, certain actions are also required, almost completely identical for all models.

Reasons for wireless networks not being detected:

1) Your router is not configured to receive a signal, it is turned off for some reason, it has started to glitch or has frozen;

2) The reason lies in the computer; the appropriate settings have not been made, hardware slider or button wireless connection disabled (it is usually located on the body);

3) The Internet has not been paid for or the provider has turned it off for other reasons;

4) The owner of the access point to which you are trying to connect unauthorizedly (without permission) is blocking your connection;

5) The antivirus program blocks the World Wide Web;

6) The IP address was not entered automatically.

There are many reasons. We won’t explain situations when the provider limits your actions or you are trying to connect to someone else’s. No, we won’t. In such cases, issues need to be resolved with the help of money or personal charm. And here all the instructions are useless.

Finding a solution

Why doesn't the computer see the flash drive? The reason could be either the computer or the flash drive. It's the same with wireless Internet.

To solve a problem, you need to classify it. On what part of the link did the failure occur?

1. The router does not receive a signal and does not allow access to the Internet.
2. The laptop does not connect to the signal transmission device.
3. The signal is transmitted, the computer sees the network, but it is still impossible to access the Internet. For some reason.

Problem #1. The router is not working.

The easiest way to make sure it is working is to connect the laptop to it via network cable. If everything is fine with the router, the Internet connection will happen.

External signs of device malfunction:

a) the corresponding indicator on the case is “silent”;
b) is missing in the administrative panel in the WAN Internet connection tab.

What can be done?

1. Turn off and turn on the router again (in case it freezes).
2. Check if the router and network card are turned on.
3. Check your connection settings to your provider. If necessary, re-enter them manually.
4. Call your provider and ask if everything is okay with the network.

Problem #2. The laptop does not connect to the router.

The device receiving the signal is working. Other computers, smartphones, phones, and the like see the router. But the specific computer does not see anything.

1. Check the network connection on your computer (in the “Network Connections” tab).

2. Check the settings of the router and laptop. Through the “Control Panel” we find network interface responsible for connection. The path to it is different versions operating system is different. But usually the adapter is labeled as “Wireless Network Connection”. Go to “Properties” and find the Internet version protocol. We go back to “Properties” and check whether the IP address, default gateway, and subnet mask are specified. It is possible that this data was not entered at all. Then we enter them (they are obtained from the router).

3. Check on the device body whether the corresponding button is turned on.
