The laptop does not see a specific wifi network. Why Wi-Fi may not work on a laptop and how to fix it. External obstacles to the signal

While developing wireless networks, developers came up with the wifi standard. This is when one or more computers are connected to wireless point access and access the Internet through it. Or through a router. Before finding out the reasons why the laptop does not see wifi, we think it would be logical to learn something about this technology.

How should the term be understood correctly?

When we ask ourselves why a laptop doesn’t see wifi, we mean that there is no Internet network. In truth, this is not entirely true. It’s just that wifi is and if a device is equipped with it, then it is certified to work in these networks, that is, it is a guarantor of normal functioning for the intended purposes. Just as there are copiers from Xerox, and there are copiers from other suppliers. However, out of habit, people call any paper multiplier a “copier”.

WiFi equipment

Among most devices for wireless access, two categories of equipment can be distinguished: “access point” and There is also an extended access point - multifunctional wifi device.

The hardware of the equipment is similar, it differs in the firmware and, as a result, in the quality of work. If you have problems with the network and you think that the laptop does not see the wi-fi router, then the problem is not always in the machine itself. May be unfinished firmware router that calls unstable connection with an access point.

Optimal choice equipment with high-quality software should include:

Reputation of the manufacturer (branded models are less likely to glitch).
Careful study of even top-class models. It is recommended to have a review with a specialist.

How to connect to wifi. Connection setup

One way is to use cable network providers and then wired connection install wifi equipment.

The next option is to connect through the appropriate access point on the provider’s local network, if such a service is provided by them.

The access point is a hardware radio wave amplifier with the function of receiving and transmitting content. A radio signal of the wifi standard arrives from the PC, which is received by it. The signal is unified for the equipment various manufacturers, which allows you not to develop thoughts like “the laptop doesn’t see wifi, it’s probably due to the incompatibility of my equipment with the access center.”

Connecting wifi in windows xp via laptop

Step-by-step setup is discussed below.

Enable with a hardware button or key combination (depending on the model). In this case, as a rule, the indicator light should light up - a light bulb indicating that the receiver is turned on.
For some laptop models, enabling the wi-fi module is provided by special instructions regulating the procedure. If necessary, check whether this is the case in the relevant documentation.
If your receiver works on Wimax technologies, using special software you can configure this operating mode.
Enable the wireless access service (right click on the My Computer icon - management - services and applications - services - wireless setup - start, if the service is not running).

If the laptop does not see the wifi router, and the system reports this, then, most likely, a special driver utility from the manufacturer is responsible for managing the wireless connection wifi equipment. Open « network" - "view available wireless networks."

If the functions wifi control the operating system should take over, you need to click on the phrase “Change advanced settings”. On the "wireless networks" tab, check the "Use Windows to configure the network" checkbox.

When you're in the zone free access, for example, in an Internet cafe, all you have to do is connect to the nearest access point found and enjoy Internet access.

Connecting wirelessly to the Internet using a laptop can be difficult for a number of reasons, often unrelated to each other. To find the reason for the lack of signal, you should start by checking the router and Wi-Fi adapter, you can with 99% identify and solve the connection problem.

Checking the access point

First of all, check the status of the router; often the equipment simply freezes and requires a restart. Therefore, if you find an atypical indication of the router, turn it off for a couple of minutes and start it again.
If it was an internal hang, then turning it on again should resolve the problem and the laptop will again detect the available Wi-Fi network. If these actions do not lead to the expected result, it is worth checking the configuration of the access point.

Often voltage drops and internal conflicts the router causes the settings to be reset, causing the device to lose not only wireless access, but also its Internet connection. This problem is solved by authorization on the router’s web interface at the following addresses:
192.168.1.1
192.168.0.1
Depending on the equipment model, the address is assigned, and login is carried out from any Internet browser. After the configuration page opens, check the settings and volume.

If the check shows that the settings have been reset to factory settings, you should configure the router (by yourself or with the help of specialists). Typically, after the reboot that follows the configuration, the laptop will find a new available Wi-Fi network. If these measures turned out to be insufficient, and the problem remains relevant, we check the laptop.

Checking the mobile computer

Our diagnosis of the problem reached a dead end at the stage of checking the access point, so we should look for a solution in the computer itself. And first let's see if it's active network hardware. On a number of laptop models there is a function key used in combination with the “Fn” key, which controls the state Wi-Fi adapter, which can be displayed on the laptop body.

First, find the LEDs on the case, they are marked with graphic values (we are interested in “antenna” or the inscription “wi-fi”). If the indication is detected and it is lit, then the wireless adapter is turned on and in this moment works. If the indication is missing or not lit, you can try to turn on the adapter. Find in top row key “F1-12” with the antenna icon, and press it while holding “Fn”.

In addition, there is a possibility that the connection is disabled by software - using the operating system. To check, go to the “Control Panel” section, which is responsible for network settings (for Windows XP – “ ”; for Windows 7 – “Change adapter settings”). Make sure that “Wireless network connection" is active; if it is disabled, right-click and select the corresponding item from the context menu.

It may turn out that the network element is completely missing from the connection lists. This means that the hardware is not installed or used in Windows. To check the functionality of the network adapter, you should open the “Device Manager” and expand the “ Network adapters" find wireless device(Wireless). If you need to turn it on, then press context item“Enable” - a computer restart may be required.
If the device is marked with an attention sign, then most likely the drivers are installed incorrectly or are missing altogether. Use the disk that came with your laptop and install the drivers first. They can also be found on the manufacturer’s official website using the model number of your computer.

P.S.

The problems described above are only some of the possible ones, the most common among ordinary users. Therefore, when looking for the cause and its further solution, it is worth starting from the individual characteristics of the situation.

Unfortunately, many of us have encountered a problem when the laptop stops finding a wireless network, which creates significant inconvenience. Considering that the laptop can be used outside the home, the user may be left without the Internet at all. There can be many reasons for this little pleasant moment. But, as a rule, the problem is technical, or it is a malfunction of the software. To understand how to deal with the problem, let's look at it in more detail.

In order to understand the causes of the problem and understand why the laptop does not find WiFi router or home WiFi network, you need to know what WiFi is and understand how this system wireless communication is arranged.

WiFi is the same as a local network, only without the need to lay a cable. Connection to the network occurs through a signal that is transmitted via radio waves. This system gained popularity not so long ago. A dozen years ago, no one knew about it, and the signal distance was much shorter. To be precise, the signal can be sent over a distance of 100 km.

In addition, WiFi is a registered brand that is developing very actively. In 2014, data transfer speeds via WiFi should increase to several Gbit/s.

To put it simply, this method of connecting to the network is now very popular. Almost every laptop has a built-in sensor that allows you to use a wireless network. At bus stops, in cafes or any other public places, owners install free points access, which increases the level of comfort of an establishment or public place.

The main reasons for the lack of WiFi

As mentioned above, the main reasons can be divided into technical and software. In the case of technical ones, the owner of a laptop will most likely have to contact a service center and spend money on repairing it. IN best case scenario, figure out the reason bad work router.

Availability of WiFi on laptop and router

It’s worth starting with the very basics, which can be forgotten due to haste or inattention.

You need to make sure that receiving antenna is in the on state. If it doesn't work WiFi button, then the problem is obvious. Not all laptop models have this switch, but some do have it. Most often it looks not like a button, but like a latch. However, it depends on the manufacturer. The switch may have a signature or image of an antenna, which indicates WiFi.

If there is no such button on your laptop model, then you need to pay attention to bottom panel operating system, on the icon next to the time. The image should show whether the wireless connection for now.

It is possible that this icon on the panel next to the time is not there.

To check activity without using this icon, you need to:

Checking available networks

The next thing to do is check the available networks. Perhaps the router simply does not reach the laptop’s antenna and for this reason it is impossible to connect to the network.

To do this you need:

Click on the network icon in the lower right corner, on the bottom panel, next to the time.
select “Connect to a network” and select desired point access. Most likely, there will be more than one access point, since you can see neighbors or some other routers. But, in most cases, a password is placed on the access point, thus protecting it from unauthorized users.

The laptop does not see the WiFi network: the main reasons

Why doesn't my laptop see the WiFi network? Perhaps the solution to the problem is right in front of you and only takes five seconds of your time. But there are also more severe cases. Let's look at the most common options.

Router

It is worth making sure that the router is turned on. Its operation can be easily determined by indicator lights. After connecting, look at the corresponding icons in the instructions for the router and determine whether it is active.

If the router does not respond at all, then the problem is purely technical. In this situation, you should look for a problem in the wires, power supply, or take the router for repair. As a rule, it is easier to replace the router with a new one than to send it to service centers for inspection.

Drivers

As you know, any equipment requires software that guarantees stable work. If the laptop does not detect WiFi, then you should check the drivers. Even if they are installed, it is recommended to update them.

Checking drivers can be done through the control panel. In the “device manager” section there is a line “network adapters”, which should contain the name of the router if the problem is with the drivers. Right-click on it and look at the driver version. Compare it with the real version, which can be found on the Internet.

If the version is outdated, then download a new one and install. It is best to download from official sources. Drivers for hardware are distributed by developers free of charge, and there is no point in risking the “health” of your operating system in vain.

Signal distance

If after searching for a network the answer appears: “No available connections- think about the signal. In apartments, this option is not very relevant, since modern routers have strong signal and spread it far enough. But in private homes or other places where the distance can be quite large, the signal simply may not reach the laptop. Therefore, you should not be surprised if the Internet suddenly disappeared while you were walking around the house or yard.

Mac address

There are situations when I was able to connect, but the router does not see the Internet through my WiFi or has stopped seeing it. When using services from some providers, the user cannot simply change the network adapter, since the Mac address changes.

The Mac address is written on each router and the user just needs to call the operator to new address tie in to replace the old one. You may be asked to dictate it in full or to specify only the last few values of the entire number.

Antivirus or third party programs

Third-party programs installed on a laptop may conflict with drivers or interfere with the correct establishment of an Internet connection, which often happens when the device sees wifi but does not connect. In addition, sometimes antiviruses interfere with creating a connection. If possible, it is better to try connecting to the Internet without a router first. If everything is fine, then the programs are not to blame.

In addition to those listed, there can be many reasons. Basically, the variety of reasons is due to problems with the operating system. Therefore, if all else fails, try reinstalling your operating system. Perhaps all the problems come from here.

The laptop does not see the WIFI network on Windows7/Windows 8/WindowsXP

For those who are wondering why the laptop does not see wifi in Windows 7, first of all, you need to try manually turning on the wireless network.

To do this you need:

In Windows 8, activity is checked through the “PC Settings” item. Next you need to select the line “ wireless connection" and move the slider on the right side of the menu to the "On" state.

A wireless network when using Windows XP does not require manual activation and, as a rule, connects like Windows 7. It is enough to activate it through the control panel or through the wireless icon through the bottom panel of the system.

Video: how to create and configure a WI-FI network

How to set up a wireless network

For comfortable use of the network, some users resort to settings. Usually enough standard settings, but if you want, you can delve into your personal account. It is through your personal account that parameters are changed.

The login and password are specified by the router manufacturers, and you can find this data in the instructions. The address that will take you to Personal Area. It is best to replace the default data so that no one can use it.

All other settings are made on the laptop itself, and they are installed using the Network Control Center.

WiFi without internet due to Windows

There are rare cases when the operating system itself does not want to determine wireless connection and shows that external network no at all. This option may exist when using non-licensed OS. Some people prefer to use amateur assemblies, which do not load the system as much and allow you to squeeze more out of the hardware.

Another reason could be a clogged system. System folders, over time, become clogged with unnecessary files and if defragmentation is not carried out, the processor will be loaded more and more. Antiviruses also cannot keep a laptop clean forever.

In any case, all problems with the OS can be solved by a simple reinstallation. After reinstalling Windows everything should work. Thus, the solution to the problem lies only in the functionality of the router, enabled WiFi on the laptop, or the presence of the necessary software. If these points are observed, WiFi will not present difficulties and will delight the user with stable operation.

A fairly common problem among owners of laptops with Windows 10, Windows 7 or 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 available connections.

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 there are no connections available. And now about ways to fix this.

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

If on this device you have never used wireless capabilities before, and now you have installed a Wi-Fi router and want to connect and you have a problem stated problem, then first I recommend reading the article.

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. If you don't know how to complete steps 2-6, everything is described in great detail (will open in a new tab). And if these options have already been tried, go to the seventh point, from which I will begin to describe in detail (because everything is not so simple there for novice computer users).

Remove the wireless Wi-Fi adapter from device manager, install it again

To start the dispatcher Windows devices, press Win keys+R on the 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.

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 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.

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

The laptop does not connect to a wireless access point or refuses to see the local network - an extremely unpleasant situation that confuses users.

Troubleshooting a problem is often complicated by the fact that there is no way to go online and see how to fix the problem. To protect yourself from getting into a hopeless situation, it is recommended that you carefully read the possible causes of problems with a wireless or local connection, as well as ways to solve the problem.

Possible reasons:

Wi-Fi module is turned off.
The wireless network is disabled.
Drivers are not installed correctly.
Incorrect router settings.

As for problems with detecting a local network when a cable is connected, the reason often lies in mechanical damage to the wire or network card.

No access to Wi-Fi network

If the laptop does not see the wireless network, then the first thing you need to do is check whether the adapter is turned on on the laptop. Take a look at the row of keys F1-F12: on one of the keys there should be a designation of the antenna receiving the signal. Find this key and press it in combination with the Fn button - for example, Fn and F2.

Some laptop models use a hardware switch instead of hot keys, which is located in the front of the case. After pressing a keyboard shortcut or applying hardware switch A message should appear indicating that Wi+Fi is on/off. Naturally, you need to put it in an active state.

But that's not all: sometimes the wireless connection in the system is turned off, while the adapter itself is working. To resolve this issue:

Open Network and Sharing Center.
Go to the "Change settings" section.
Find your wireless network and make sure it is working.

If the adapter is turned on, the wireless network is active, but you still cannot access the Internet, then it makes sense to check the Wi-Fi drivers. This is especially true if connection problems began after reinstalling Windows.

Right-click the Computer icon.
Open the Manage tool.
Go to Device Manager.
Find the wireless connection module among the network adapters.

Even if it says that the equipment works correctly, do not be lazy to go to the official website of the laptop and download drivers for Wi-Fi module exactly your laptop model.

Checking router settings

If the laptop does not pick up the wireless network, but you see that everything is fine in the system, then you should pay close attention to the router. Make sure the alarm device is working correctly. Go to its web interface and look at the Wi-Fi settings.

Enter the router's address in the browser (192.168.0.0 or another specified on the router).
Open advanced settings and make sure Wi-Fi is turned on.
Save correct configuration and close the router interface.

After applying the new configuration, try connecting to your wireless connection again. For it to appear in the list of available networks, turn off and turn on the Wi-Fi adapter on your laptop.

Local network problems

We've figured out the wireless connection, now let's look at a more complex situation - the device doesn't see local network, although you connected the Internet cable to the network card connector. What to do in this case?

First check if the wire is damaged. Often it is the faulty state of the cable that leads to the fact that the laptop cannot detect the local network. If the wire is broken or cut, it needs to be replaced.

The second step is to check the network card connector into which the Internet cable is inserted. If you removed the wire carelessly or dropped the laptop, the connector could be damaged. The problem is solved in service center, where your broken port will be replaced. Another unpleasant situation this kind- burnt network card. It is also better to entrust the operation of replacing it to specialists: after all, a laptop is not a computer where modules can be changed at home.

But before you go to the service, be sure to check the network card drivers: they may have failed. This can be done through the “Device Manager”, the launch procedure for which we described above. The principle is the same - download drivers for the network card from the official website of the laptop manufacturer and install them, and then check again whether the local network is detected.

Every person using personal computer, it is very common to encounter problems connecting to Wi-Fi. Situations arise when a laptop or other device does not see the wireless network, or it is incorrectly displayed in the list of available connections. It also happens that the network is connected, but data transfer does not occur.

There are many reasons why such a problem arises. And in order to correct this, you first need to determine why such a malfunction could occur. The first reason this happens is that the laptop refuses to find any available points nearby Wi-Fi access. The other one cause depends on the wireless network source. And in such a situation, the computer, on the contrary, sees everything Wi-Fi zones, except the one you need to connect to.

You should always start diagnosing a malfunction by finding out the causes. And then proceed according to the plan below to identify the culprit of the problem:

Is the router working correctly and is it accessible to connect? dot Wi-Fi? Can other devices that have a Wi-Fi receiver see the router's signal?
Are there other wireless network sources nearby? And how do they appear in the list? network connections computer or smartphone?

Fixing the problem using Windows 7 or 8

When it turns out that the router is properly distributing a signal and other devices are detecting it, but the laptop does not see Wi-Fi even from neighboring routers, this indicates that adapter the laptop has failed or is simply disabled by software or hardware. To be sure of this, you need to:

Launch Device Manager and find “Network Adapters” in the list.
The sub-item that appears should contain all network devices, the list of which should include a wireless adapter. Each laptop model may have a different designation. Its exact name must be in technical specifications, which can be found on the manufacturer's website.
It is also necessary that there are no additional icons in the line with the name of the network device yellow color with a sign exclamations(this is a warning that the device is disabled or the wrong driver is installed on it).
First you need to try to turn on Wi-Fi. To do this you need to call context menu on the line with the name of the adapter and select the “Engage” command.
If this method does not help, then you need to try reinstalling the device drivers. To do this, you need to download them from the manufacturer’s website and install them again.
You can also remove the adapter from the device manager list and restart the computer. And after turning it on and loading, open the manager again and check whether the Wi-Fi adapter is detected correctly. If it displays as " Unknown device", then install pre-loaded drivers.

You can use another method to check functionality wireless card Wi-Fi. To do this, you need to go to the “Control Panel” and find the “Network and Sharing Center...” section there. Then go to the “Change adapter settings” item in the left column of the window. When Wi-Fi is turned on and working normally, the “Wireless” icon network connection"There should be no red crosses and other additional characters. If the adapter shortcut says “Disabled”, then you can launch it by calling the context menu and clicking on the “Enable” command.

Hardware problems

Besides, Wi-Fi card can be enabled using function keys and laptop switches. In this case, you need to look on the keyboard among the buttons (F1-F12) for a symbol indicating Wi-Fi standard. And by pressing the Fn key along with this icon, you can start the device. Exact location this button or the switch can be found by reading the laptop manual. Similar keyboard shortcuts are made to quickly turn off the Wi-Fi signal during an airplane flight, and can have an airplane symbol on the laptop keyboard. It all depends on the manufacturer and model of the device.

Another reason for adapter failure may be recent repairs or cleaning of dust from the laptop. It is possible that the card may have been damaged or connected incorrectly during assembly. Under such circumstances, it is necessary to either change the adapter to a working one, or correctly install it in the slot intended for this. You should also pay attention to the wires going to it. It is possible that one of them could have been damaged when assembling the laptop after servicing.

There are times when a laptop does not see all Wi-Fi networks, while other computers and gadgets connect normally to the router. The first thing, of course, is to try rebooting the router. To do this, you need to disconnect it from the power supply for 20-30 seconds and wait until it boots up completely.

If this simple method did not help and the computer still stubbornly refuses to connect to Wi-Fi, then you need to proceed as follows:

First, you can try changing the encryption type in the wireless network configuration of the adapter or router. It’s also worth trying to change the number of the channel on which the signal is broadcast.
You can also rename the network, giving it a simpler name consisting of ordinary Latin letters.

Another problem due to which Wi-Fi on a laptop does not connect may be viruses in operating system and technical malfunctions of the network card. Such a malfunctioning adapter is capable of displaying list of networks, but do not connect to them. For example, due to corrupted software embedded in its controller.

However, the source of the problem can be not only a laptop, but also an incorrectly configured and operating router. To solve problems connecting to a wireless network, you need to:

Reset the router software to factory default settings. And enter new values into its settings.
Check what firmware is installed on the router and how up-to-date it is. If software router is outdated, you need to download more new version and update your device.

It is recommended to periodically monitor the availability of new firmware and update the router when new software becomes available. This can not only improve its performance and remove some errors in its operation, but also provide reliable security.

In addition to connection difficulties, there are also indirect problems that create a lot of trouble when using a Wi-Fi network. One of these inconveniences may be slow speed transmitting information over a wireless network. And her reasons are:

Very a large number of users connected to a Wi-Fi access point.
Incorrect router placement. A router that is located far away or poorly installed in a room may not reach the Wi-Fi signal to the computer, especially if it is a laptop with which people often move from one place to another. To do this, it is better to place the access point where there is an equal distance to it from all corners of the room or house.
Interference from other sources. Signal quality often suffers due to sources of other wireless networks emerging nearby. They can cause interference and slow down your connection speed. This has a particularly strong effect when such a source is more powerful router installed by neighbors. Another reason could be nearby office buildings equipped with many such access points.
Low-quality or cheap router issued by your provider. Many companies that provide Internet access purchase inexpensive equipment to save their costs. This allows you to reduce the connection price, but creates some inconvenience for the user. Therefore, before concluding a contract, it is better to consult with technical support and purchase a more powerful router.

The data transfer speed is also affected by constantly turned on torrents and media files and online games viewed on the network. If you need to get maximum speed connection, then at this time it is better to disable all traffic-consuming applications.

Wi-Fi technology has long been included in daily life many people. Today, almost all homes have their own wireless network access point. With its help, various mobile devices, desktop computers, and laptops are connected to the Internet. It often happens that for laptop PCs, a wireless network is the only way to access the Internet. But what to do if there are problems with the network and the laptop simply does not catch it? This article will discuss ways to solve this problem that are accessible to an untrained user.

All methods for correcting improper Wi-Fi operation on a laptop PC can be divided into two types. The first includes checking and changing the settings of the computer itself, the second - related to the configuration of the distribution device itself. The emphasis will be on the most common reasons inoperability of Wi-Fi, and in terms of methods - on those available for regular user solutions to such problems.

Method 1: Checking Drivers

One of the most common reasons why a laptop PC cannot connect to a wireless network is the lack of Wi-Fi adapter drivers. It happens that a user has reinstalled or updated the current Windows OS, but forgot to install device drivers.

Drivers for Windows XP, for example, are very often incompatible with newer versions of Windows. Therefore, when updating this OS, you first need to make sure that you have the necessary software for the Wi-Fi adapter.

If we talk about laptops, then here we should dwell on an important point: it is recommended to download and install the appropriate software only from the official website (or the included disk) of the manufacturer. Usage third party applications to search for drivers network devices often leads to Wi-Fi not working properly.

To check the status of the network adapter, do the following:

If this is not the case for you, then the problem lies in the adapter drivers. There is a simple method that is recommended first:

If such actions do not bring results (or the adapter simply does not appear in "Device Manager"), which means you need to install the appropriate driver. The main idea is that you should search for software for the adapter based on the name of the specific laptop model. For search official drivers we will use search engine Google (you can use any other one).

By following the link provided in the search engine, enter the name of the laptop PC model + “driver”.

IN search results A list of resources will be displayed. It is best to choose the official website of the laptop manufacturer (in our case, Asus.com).

Since we entered in the search specific name computer, we can immediately go to the appropriate page for this model.

Click on the link "Drivers and utilities".

The next step is choosing an operating system.

The site will display a list of drivers for the selected version of Windows.

Let's move on to the Wi-Fi adapter driver. As a rule, the name of such software contains words like: "Wireless", "WLAN", "Wi-Fi" etc.

Click on the button "Download"(or "Download").

Save the file to disk.

Next, after unpacking the archive, install the driver into the system.

Method 2: Enable the adapter

Another fairly obvious reason for inoperability Wi-Fi connection on a laptop - disable Wi-Fi itself. This can happen either as a result of user actions or while applications are running. A ban on using the adapter can be set in the operating system settings. In Windows, a tray icon will appear indicating that Wi-Fi cannot be used.

Checking BIOS settings

As a rule, on new laptops, the Wi-Fi adapter is turned on by default. But if the user made changes to the BIOS settings, the wireless connection may be disabled. In such cases, no actions in the operating system itself will be able to launch Wi-Fi. Therefore, you first need to make sure that permanent memory The laptop should not be banned from using the network adapter.

Wireless Properties

Calling up the menu "Start" by pressing the key "Win".
Next, select "Control Panel".

Click on the menu and select "Large Icons".

Next we go to "Network Control Center and shared access» .

Click on the network adapter properties link.

In the window, find the wireless connection icon and select it with RMB.
Select from the menu "Turn on".

device Manager

Leads to the same result turning on Wi-Fi adapter via "Device Manager".

Method 3: Disabling Airplane Mode

Function "In airplane" designed specifically to instantly disable all wireless connections on your computer. It turns off both Bluetooth and Wi-Fi. Sometimes beginners use this feature by mistake and encounter Wi-Fi inoperability. It is clear that in our case this mode should be set to "Off".

An indicator that the PC is in this mode is the airplane icon in the tray to the right of the taskbar.

In Windows 8, the connection menu looks different. Click on the Wi-Fi icon in the tray and then click on the switch. The inscription should change to "On".

Method 4: Disable Power Saving Feature

When your laptop wakes up from sleep mode, you may encounter that the network adapter does not connect to the network. Windows simply turns it off while you sleep, and then various reasons may not turn it on again. Run it often programmatically without rebooting the OS becomes problematic, if not impossible. This reason is especially relevant for computers with Windows 8 and 10. To sleep Wi-Fi mode module is no longer bothering you, you need to do some settings.

Let's go to "Control Panel" and choose "Power supply".

Let's move on to the settings of a specific power plan.

Next, click the mouse to change additional parameters.

Click on the drop-down list of parameters for the Wi-Fi communication module.

Next, open the submenu by clicking on the cross and set the constant maximum performance for the device.

To disable sleep mode for our Wi-Fi device, do the following:

Method 5: Disable Fast Boot

Function quick launch introduced in Windows 8 often leads to incorrect operation various drivers. To ban it, follow these steps:

Method 6: Disable FIPS Mode

In Windows 10, unlike previous versions of this OS, the default operating mode is compatible with the Federal Information Processing Standard (or FIPS). This may affect normal functioning Wi-Fi. If you have installed something other than the tenth Windows versions, then it is recommended to check this parameter as well.

Hold down the keys "Win + "R", enter in the line "ncpa.cpl" and click "Enter".

Next, RMB select the wireless connection and click on "State".

Click on the button to access the connection properties.

Move to the tab "Safety".

Click on the button « Extra options» at the bottom of the window.

Next, if there is a checkmark, remove it.

Method 7: Router Settings

If changes were made to the router settings, this may also be one of the reasons for the computer’s inability to detect the Wi-Fi network. Even if all the necessary drivers are present on a system with a properly configured network Windows configuration The router may prohibit the use of wireless communication. Exists great amount routers that differ functionality And proprietary firmware. Next we will consider general recommendations using the example of one router model ( Zyxel Keenetic).

All modern routers have a web interface through which almost all parameters of the device’s operation and network configuration can be configured. Typically, to enter the router settings you need to enter address bar browser "192.168.1.1". This address may differ on some models, so try entering the following values: "192.168.0.0", "192.168.1.0" or "192.168.0.1".

In the dialog box for entering login and password, the router, as a rule, provides all necessary information. In our case, “admin” is the login, and 1234 is the password for accessing the web interface.

All necessary data to access the settings of a specific router model should be found in the included instructions or use an Internet search. For example, enter the name of the router model + “settings” into the search.

The appearance of the interface, the names of specific elements and their location may vary greatly for each model, so you must be sure of what you are doing. Otherwise, the best thing is to entrust this task to a specialist.

Wireless Resolution

It happens that users connect to the router using network cable. In such cases, they do not need a Wi-Fi connection at all. Then the wireless functions in the router settings may be disabled. To check such settings, we will show an example with Zyxel router Keenetic.

Here we see that in the section responsible for Wi-Fi, wireless communication is allowed. The designations can be different: “WLAN Enable”, “Wireless ON” and even “Wireless Radio”.

On some models, you can turn Wi-Fi on or off using a button located on the case.

Disable filtering

Another feature we need to look at is filtering. Its purpose is to protect home network from various connections from outside. The Zyxel Keenetic router is capable of filtering both by MAC addresses and IP. Filtering works selectively on incoming and outgoing traffic certain ports and URL. But we are only interested in incoming ban. In the web interface Zyxel settings locks are in the section "Filters".

The example shows that blocking is disabled in principle, and there are no entries in the table of blocked addresses. In other device models it may look like: "WLAN Filtering Disable", "Filtering Off", "Block Address Disable" etc.

The situation is similar with IP blocking settings.

Change channel

Neighboring wireless networks or some electrical appliances may cause interference on the channel Wi-Fi work. Each Wi-Fi network operates on one of the channels (in Russia from 1 to 13). The problem arises when several Wi-Fi networks are located on one of them.

If the user lives in a private house, then there will probably be no other networks within the operating radius of his adapter. And even if such networks exist, their number is small. IN apartment building the number of operating Wi-Fi networks can be significantly larger. And if several people simultaneously configure the same router for their static channel, then interference in the network cannot be avoided.

If the router settings have not been changed, then by default it selects the channel automatically. When the adapter is plugged into the network, it simply “sits” on the channel that is currently free. And so every time you reboot.

It should be said that only a faulty router may have problems with automatic channel selection. And in most cases, changing the channel is not a solution to the interference problem. Constant manual determination of these parameters is still a pleasure. But as a way to gain access to the network at the moment, this option is worth considering.

To check the channel selection settings of the transmitter, you need to go to the familiar web interface. For example, for Zyxel Keenetic these parameters are in the section "Wi-Fi network" — "Compound".

From the example you can see that in the settings you have selected auto mode channel selection. To check the current operation of channels, you can use the WifiInfoView program.

Some router models display Additional information about channel congestion.

Quite often, simply rebooting the router helps. As a rule, this is the very first recommendation from the provider's support service for any network problems. Let's consider several options for how to restart the distribution device.

Power button

Most often, on the back side of the router case there is special button, responsible for turning the device on/off.

The same result can be achieved if you simply unplug the power plug from the outlet and wait at least 10 seconds.

Reset button

Button "Reset" in its main mode allows you to reboot. To do this, you need to press it with something sharp (for example, a toothpick) and then immediately release it. If you hold it longer, reset will occur all settings of the distribution device.

Web interface

You can use the device console to reboot the router. After entering the router settings, you need to find the reboot button itself. Where it will be located depends on the firmware and model of the device. For example, for Zyxel Keenetic this function is available in the section "System" in point "Configuration".

By pressing the button, we reboot.

Method 9: Network reset

Reset network settings returns the network configuration to its original state and reinstalls all adapters in the system. This method is recommended only as a last resort, as it makes dramatic changes to many system settings.

Windows 10

If you have Windows version 10 (build 1607 or later), then do the following:

Windows 7

The wireless network problem may be resolved. If not, you should try resetting TCP/IP directly. To do this you need:

Thus, there are quite a lot of ways to restore Wi-Fi operation available to the average user. First of all, you need to make sure that the BIOS settings are correctly configured and that all drivers for the network adapter are available. If this does not work, check the power supply modes installed in the operating room Windows system. AND last step— working with the configuration of the distribution device itself.

We have already looked at solutions to many problems that may arise when connecting a laptop to a Wi-Fi network, or during use. But, there is one popular problem that I have not written about yet. This is when the laptop does not see the Wi-Fi network. In principle, the problem applies not only to laptops, but also to desktop computer that are connected to Wi-Fi via an adapter (external or internal). The problem when the laptop does not see Wi-Fi can be encountered in Windows XP, Windows 7, Windows 8, and even in Windows 10. If you have Windows 10 installed and the computer does not see your router, then see separate instructions:. Since the solutions there are practically the same, it doesn’t matter what system your laptop is running on. Now we will try to figure out why the laptop does not see wireless networks, on Windows example 7.

Before moving on to any settings, let's try to figure out what problem you specifically have. There are two options:

When no Wi-Fi network is displayed in the list of networks available for connection. That is, the computer does not find Wi-Fi at all. But, are you sure that there are wireless networks within the radius? Other devices see them.
And when the laptop does not see only your Wi-Fi network, but others, neighboring networks sees.

I will divide this article into these two parts. You can immediately go to the required section with the solution to your problem.

Another important point. If you have an error on your computer "No connections available", and a red cross next to the Wi-Fi connection icon, then there is a separate solution to solve this error.

Why doesn't my laptop see wireless networks (not a single one)?

The most popular reasons:

No in radius available networks (we have already ruled this out)
The wireless adapter driver is not installed and therefore cannot find wireless networks. Or the driver is installed, but does not work correctly.
Wi-Fi on the laptop is simply turned off.
It happens that Wi-Fi receiver simply faulty or disabled (for example, while cleaning a laptop from dust).

But, most often, of course, the problem is that the wireless adapter, or in the absence the required driver. This is what we will consider now.

Checking the wireless adapter driver

If you see a connection icon in the form of a computer with a red cross on your notification panel, then the driver is most likely not installed.

To check, we need to go to the device manager. Open menu Start, right click on Computer, and select Control. In the new window, go to the tab device Manager. Open section Network adapters, and see if there is an adapter whose name contains the words “Wi-Fi” or “Wireless”. It looks something like this:

If such an adapter is not there, as a rule, in this case only one adapter is displayed there ( LAN card), then you need to install it. If it is there, then it should be without any icons, like in my screenshot above. If there is an icon near the Wi-Fi adapter, then right-click on it and select Engage. Most likely you will have to install required driver. We have separate instructions for installation: .

If everything is fine with the driver, then let's Let's check if Wi-Fi is turned on on your computer.

Right-click on the network connection icon, and select Network and Sharing Center. Then, select Change adapter settings.

After this, the computer should see wireless networks, and you can easily connect to your Wi-Fi network.

You may have wireless networks turned off by a keyboard shortcut on your laptop. You need to check, I wrote about this in more detail in the article:. And if you have a “ten”: .

After these steps, everything should work for you. The main thing is that he appears wifi icon networks with a yellow asterisk, this means that there are networks available for connection.

The laptop does not see my Wi-Fi, but does see others. Solution to the problem.

If above we considered the situation when the laptop does not display wireless networks at all, now we will figure out why the laptop does not see only one Wi-Fi network that we need. And other networks, neighboring ones, are displayed in the list of available ones. This problem appears more often on mobile devices: smartphones and tablets. But computers are no exception.

In this case, the problem needs to be looked for on the side Wi-Fi router. Almost always, the solution is the same: change Wi-Fi channel networks. If the router itself, or you are in manual mode If you set the settings to static channel 13, then the computer most likely will not see the network. Therefore, you need to check and change the channel in the router settings. I wrote in the article how to change the channel on different routers:

For example, change the channel on Tp-Link. You can change it in the settings, on the Wireless tab (Wireless mode) . Try setting a static channel (just don't put 12 and 13), or set to Auto.

If it doesn’t help, you can still change it Wi-Fi name networks. You can also do this in the settings, on the wireless network settings tab.

Another tip: try moving your laptop closer to the router, or vice versa. Perhaps this is the problem. There are often cases when Wi-Fi catches even close to the router, but on a short distance does not work. This is of course not normal, but I don’t know of any specific solution. Again, you need to try experimenting with channels.

Hello! Yes, I will write again about problems with Wi-Fi :). Someone needs to fight capricious wireless networks, which usually provide more inconvenience during setup than pleasure during use. A lot different problems arises, and most of them are difficult to even explain.

Today I will write about one of these problems. And I will give some recommendations that may help you solve it. But I can’t guarantee anything, I hope you understand.

What does the problem look like?

I think that after reading the title of this article, you can already understand what this article is about. I began to notice comments in which people wrote that their devices, be it a laptop, a computer with an adapter, a phone, a tablet, game console, does not see their home Wi-Fi network. It is simply not in the list of networks available for connection. At the same time, the device sees neighboring networks. But why? I thought for a long time, but could not come up with a logical explanation for this problem.

By the way, such nonsense can occur even after some work with Wi-Fi, that is, everything was working, you turned off the laptop (for example), and turned it on, but it no longer sees your network.

Here you need to act quickly and save your phone or other equipment from flying into a wall or window :)

Attention! This article is about when a device does not see a wireless network, but only, for example, one network, while other neighboring networks are detected.

The device does not see Wi-Fi [possible solution]

Roman left the following comment on the site:

To be honest, I didn't know what to recommend. But then I thought again and realized that, as a rule, the most strange problems arise due to the channel on which the wireless network operates, more precisely through interference on the channel.

And I advised you to experiment with channels, as written in the article. Roman changed channel (unfortunately, he didn’t write which one he installed, but it doesn’t matter, you need to experiment) and everything worked for him. The laptop saw the network. Free channel can be determined using the InSSIDer program.

I don’t know if changing the channel really helped, or just rebooting the router 🙂 but the problem was solved. By the way, Reboot the router first if any problems arise. Easy reboot it helps a lot.

There was also a comment where the game console stopped seeing the home wireless network. But I don’t know how it all ended.

You can also try experimenting with the mode of operation of the router, I wrote about this in the article.

Perhaps you have already encountered this problem and somehow solved it differently, or please leave your thoughts on this issue in the comments. And I will update the article and add useful material.

Bye everyone!
