Basically, this problem applies to laptops, which have long been equipped with wireless modules by default, but computers on which the adapter was installed. both external and internal.
There may be enough reasons for the problem:
- Errors when loading the router or the computer itself.
- Driver problems on the receiving device.
- Dispenser software problem.
- Oxidized contacts or disconnected adapter after cleaning.
In general, the first step that you need to take in any case is to reboot both devices, and if the problem persists, try connecting from some other device. for example, from a phone, in order to understand on which side the problem is.
If the router is NOT new and you have been using it for quite some time, then the settings are unlikely to fail, unless the firmware has flown.
If you use an internal adapter, which connects directly to the motherboard (in the case of a stationary computer), then you should remove the device and check the contacts. oxidation rarely happens, which will need to be eliminated.
Also do not forget that sometimes the adapter on laptops can turn off by itself, so before sounding the alarm, just check if it is turned on. On some models, you can find a separate button with an indicator, and on the second, activation occurs using a key combination. usually [Fn] plus one more key marked with a wireless network.
The last of the simplest is the rare case when, after cleaning, the wizard forgets to connect the Wi-Fi receiver, so if you recently cleaned, then it is worth checking this particular reason.
Now let’s try to figure out together why, after all, your Wi-Fi adapter does not work.
The problem is on the receiving device
If overloads and other simple methods did not help you, then at least you have already performed diagnostics for a start. If the phone and everything else that you tried to connect sees the network and works fine with it, then the problem, of course, is on the computer side.
For those who did not want to find a network for any of the connected devices, it is better to go directly to the next section.
And now we will consider two options:
- The problem occurred during the first connection.
- The problem arose after a fairly long and normal operation.
In the first case, most likely, you simply did not have the drivers installed. the only correct solution in this case would be to search for the official software. If you installed a third-party adapter, then a disk should have come with it, from where everything should be installed, and if it is a built-in adapter, as in the case of a laptop, the manufacturer’s website will help you. find out the model of your laptop, go to the company’s website and enter the model name there. then choose the required driver or download the full.
In the second case, it is worth doing the following operation:
- Open the Start menu, find “My Computer”, right-click and look for “Properties”.
- Now we find on the left “Device Manager”. a new window will open in front of you, in which you need to find the item relating to network adapters.
- Find the required sub-item with the Wi-Fi signature, press the right mouse button again, then select “Delete” and confirm the selection.
- A little higher, we click “Update configuration” and see how the computer finds the adapter again.
In total, after reinstalling the hardware, the drivers should be back in place, and everything will work as it should. It will be even more effective to install the driver manually from a file downloaded from the manufacturer’s official website.
If none of the above helps, right-click on the signal strength icon in the panel. Now our goal is the “Network Management Center”.
Now find the icon “Change adapter settings”.
Inside you will find an icon of the network with a red cross that we tried to connect to. we double-click on it and inside we look for “Internet Protocol version 4”.
In the general tab, set both parameters to automatic receipt and now just click the confirmation on all open tabs sequentially.
Now we figured out the problem due to which the Wi-Fi adapter on the receiving device does not turn on, and now we move on.
The problem is on the side of the distribution point
If Wi-Fi is turned on, but does not see the network, then perhaps the problem is hidden in your router.
Quite rarely, but it happens when an old router and a new laptop (or vice versa) do not want to “see” each other. this is due to the different frequencies at which the devices operate, so try NOT to use equipment of different generations.
All you can do if the problems are on this side is to rearrange the firmware, since the problems are most likely in it, or the router has simply worked its way out. Such a problem is rather difficult to detect, since even when entering the settings on the flashed firmware, everything can happen as usual, but some functions will be blocked.
To perform a flashing, you again need to go to the manufacturer’s official website and download the software there and read the instructions for this operation.
If, after all that has been done, the reason why the Wi-Fi adapter does not see the network is not found, you can safely go for another router.
How to troubleshoot wireless network connection problems
and more users prefer wireless Internet, but with the advent of Wi-Fi, there are also difficulties that accompany the connection over the air. Therefore, today we will figure out in detail why the Wi-Fi adapter does not see the network and what to do about this problem.
What to do if Wi-Fi doesn’t work? Easy solution to the problem
I have extensive experience in setting up and connecting access control systems (ACS) and time attendance systems. And also I am engaged in setting up servers, computers, workplaces.
I work as an engineer at Technootkrytie.
Additional reasons why the laptop may NOT connect to Wi-Fi or not see the network
In addition to the options suggested above, there may be other reasons for problems with the Wi-Fi network. Very often. the problem is that the settings of the wireless network have been changed, less often. that it is not possible to use a certain channel or wireless network standard. Some of these problems have already been described on the site earlier.
In addition to the situations described in these articles, others are possible, it is worth trying in the router settings:
- Change the channel from “auto” to a specific one, try different channels.
- Change the type and frequency of the wireless network.
- Ensure that no Cyrillic characters are used for the password and SSID.
- Change network region from RF to USA.
Enabling Wi-Fi using keys and hardware switch
On many laptops, in order to enable the ability to connect to wireless Wi-Fi networks, you need to press a key combination, one key, or use a hardware switch.
In the first case, to turn on Wi-Fi, either just a function key on a laptop is used, or a combination of two keys. Fn, the Wi-Fi enable button (may have an image of the Wi-Fi logo, radio antenna, aircraft).
In the second. just the switch “On”. “Off”, which can be located in different places of the computer and look different (you can see an example of such a switch in the photo below).
As for the function keys on the laptop to turn on the wireless network, it is important to understand one nuance: if you reinstalled Windows on the laptop (or updated it, reset it) and did NOT bother installing all the official drivers from the manufacturer’s website (but used the driver pack or assembly of Windows, which Allegedly installs all drivers), these keys most likely will not work, which may lead to the inability to turn on Wi-Fi.
To find out if this is the case, try using other actions provided by the upper buttons on your laptop (only Considering that the volume and brightness can work without drivers in Windows 10 and 8). If they also do not work, apparently, the reason is just the function keys, there is a detailed instruction on this topic here: The Fn key does not work on a laptop.
Usually, not even drivers are required, but special utilities available on the official website of the laptop manufacturer and responsible for the operation of specific equipment (which include function keys), for example, HP Software Framework and HP UEFI Support Environment for Pavilion, ATKACPI driver and hotkey-related utilities for Asus laptops, function key utilities and Enaergy Management for Lenovo and others. If you do not know what specific utilities or driver are required, look on the Internet for information about this in relation to your laptop model (or tell the model in the comments, I will try to answer).
Enabling wireless networking in Windows 10, 8, and Windows 7 operating systems
In addition to enabling the Wi-Fi adapter with the laptop keys, you may need to enable it in the operating system. Let’s see how the wireless network is enabled in the latest versions of Windows. Also on this topic, the instruction on All available Wi-Fi connections in Windows may be useful.
In Windows 10, click on the network connection icon in the notification area and check that the Wi-Fi button is on, and the button responsible for the “airplane” mode is off.
In addition, in the latest version of the OS, enabling and disabling the wireless network is available in Settings. Network and Internet. Wi-Fi.
If these simple points DO NOT help, I recommend more detailed instructions for this particular version of the OS from Microsoft Wi-Fi does not work in Windows 10 (but the options outlined later in the current material may also be useful).
In Windows 7 (however, you can also do this in Windows 10), go to the Network and Sharing Center (see How to enter the Network and Sharing Center in Windows 10), select “Change adapter settings” on the left (you can also press the Win R keys and enter the ncpa.Cpl command to get into the list of connections) and pay attention to the wireless network icon (if it is there, you can skip this section of the instruction and go to the next one about installing drivers). If the wireless network is in the “Disabled” (Gray) state, right-click on the icon and click “Enable”.
In Windows 8, it is best to proceed as follows and perform two actions (since two settings, according to observations, can work independently of each other. in one place it is enabled, in the other it is disabled):
- In the right pane, select “Settings”. “Change computer settings”, then select “Wireless” and make sure it is enabled.
- Follow all the steps that are described for Windows 7, i.e. Make sure the wireless connection is enabled in the connection list.
Another action that may be required for laptops with Windows preinstalled (regardless of version): run the program for managing wireless networks from the laptop manufacturer. Almost every laptop with a preinstalled operating system also has a program that contains Wireless or Wi-Fi in the name. In it, you can also switch the state of the adapter. This program can be found in the Start menu or All Programs, or it can add a shortcut to the Windows Control Panel.
The last scenario. you reinstalled Windows, but did not install the drivers from the official site. Even if the drivers for Wi-Fi were installed automatically during Windows installation, or you installed them using a driver pack, and in the device manager it shows “The device is working normally”. go to the official website and get the drivers from there. in the overwhelming majority of cases this solves the problem.
How to find out which Wi-Fi driver is on your computer
In any version of Windows, press the Win R keys on your keyboard and enter the command devmgmt.Msc, and then click OK. Windows Device Manager will open.
Wi-Fi adapter in device manager
Open the “Network adapters” item and find your Wi-Fi adapter in the list. Usually, it has the words Wireless or Wi-Fi in its name. Click on it with the right mouse button and select “Properties”.
In the window that opens, open the “Driver” tab. Pay attention to the items “Driver supplier” and “Development date”. If the supplier is Microsoft, and the date is several years away from today, go to the official website of the laptop. How to download drivers from there is described at the link that I gave above.
Update 2016: in Windows 10, the opposite is possible. you install the necessary drivers, and the system itself “updates” them to a less efficient one. In this case, you can rollback the Wi-Fi driver in the device manager (or downloaded it from the official website of the laptop manufacturer), and then disable automatic updating of this driver.
After installing the drivers, you may need to enable the wireless network, as described in the first part of the instructions.
How to turn on Wi-Fi on a laptop
Not all laptops have the wireless network module enabled by default: in some cases, you need to perform certain actions for it to work. It is worth noting here that everything described in this section is fully applicable only if you did NOT reinstall Windows, replacing the one that was installed by the manufacturer. If you did this, then some of what will be written about now may NOT work, in this case. read the article further, I will try to take into account all the options.
Wi-Fi not working on laptop
This manual describes in detail why Wi-Fi connection on a laptop may NOT work in Windows 10, 8 and Windows 7. Next, step by step describes the most common scenarios related to the health of a wireless network and how to solve them.
Most often, problems with the Wi-Fi connection, expressed in the absence of available networks or access to the Internet after connection, occur after updating or installing (reinstalling) the system on a laptop, updating drivers, installing third-party programs (especially antiviruses or firewalls). However, other situations are also possible, which also lead to the indicated problems.
The material will consider the following main options for the situation “Wi-Fi does not work” in Windows:
- I can’t turn on Wi-Fi on my laptop (red cross on the connection, a message stating that there are no available connections)
- The laptop does not see the Wi-Fi network of your router, while it sees other networks
- The laptop sees the network, but does not connect to it
- The laptop connects to a Wi-Fi network, but pages and sites do NOT open
In my opinion, I have indicated all the Most probable problems that may arise when connecting a laptop to a wireless network, let’s start solving THESE problems. You may also find useful materials: Internet stopped working after upgrading to Windows 10 Wi-Fi connection is limited and without Internet access in Windows 10.
Wi-Fi won’t turn on after Windows 10 update
- At the command prompt as administrator, enter the command netcfg.S n
- If in the answer, which you get in the command line there is a DNI_DNE item, enter the following two commands and after they are completed, restart your computer
The second option is if you had some third-party VPN software installed before the update, uninstall it, restart your computer, check the Wi-Fi function and, if it works, you can install this software again.
Perhaps all that I can offer on this issue. I will remember something else, I will supplement the instructions.
Wi-Fi is on, but the laptop cannot see or connect to the network
In almost 80% of cases (from personal experience), the reason for this behavior is the lack of the necessary drivers on Wi-Fi, which is a consequence of reinstalling Windows on a laptop.
After you have reinstalled Windows, there are five options for events and your actions:
- Everything was determined automatically, you are working on a laptop.
- You are Installing separate drivers, which are NOT defined, from the official site.
- You are using a driver pack to automatically install drivers.
- Some of the devices were NOT detected, well, okay.
- Without exception, all drivers are taken from the manufacturer’s official website.
In the first four cases, the Wi-Fi adapter may NOT work as it should, even if the device manager shows that it is working properly. In the fourth case, it is possible that the wireless device is completely absent from the system (i.e., Windows does not know about it, although it is physically there). In all THESE cases, the solution is to install drivers from the manufacturer’s website (the link is the address where you can download official drivers for popular brands)
Laptop connects via Wi-Fi but sites DO NOT open
If the laptop (as well as the tablet and phone) are connected to Wi-Fi but the pages DO NOT open, there are two options here:
- You have NOT configured the router (at the same time, on a stationary computer, everything can work, since, in fact, the router is NOT involved, despite the fact that the wires are connected through it), in this case you only need to configure the router, Detailed instructions can be found here: https : //remontka.pro/router/.
- Indeed, there are problems that can be easily solved, and in how exactly to find out the cause and fix it you can read here: https://remontka.pro/bez-dostupa-k-internetu/, or here: pages in the browser do not open ( while some programs have the Internet).
That, perhaps, is all, I think among all this information you can extract for yourself exactly what is right for your situation.
The computer does NOT detect a wireless Wi-Fi network
There are times when Wi-Fi stops being available on the computer. Why this happens and what to do in each case will be discussed in this article.
The problem can be of two types: the computer does not see the Wi-Fi network at all, or there is only your access point in the list of available neighbor networks. In the first case, the problem is most likely in the Wi-Fi device, in the second. in the computer on which the network disappeared.
The laptop does not see the Wi-Fi network adapter. First steps
What should be done first? You can restart a router or a computer on which the network is gone. Make sure to enter the correct password and not enable Caps Lock. If the Passphrase is correct, but the computer does NOT connect, then you need to look for other reasons.
If the computer does not see any access points at all and / or has stopped seeing them: you need to check if the Wi-Fi adapter is active. It is necessary to do this: on the computer keyboard, press the key combination “FnF3” (depending on the model and manufacturer, there may be a combination of “FnF2” or “FnF5”). For the keyboard shortcuts to work, the keyboard drivers must be installed. On older models, the ability to see Wi-Fi is sometimes turned on with a separate button.
If the problem is that the computer does not see only your router, but sees others, then you need to do the following steps. Find the settings of the router and check the operation of the Wi-Fi adapter. To do this, open a browser and enter http://192.168.1.1 or http://192.168.0.1 in the address bar. If it did not work out, the data on the ip-address and authorization in order to enter the page can be taken from the sticker attached to the back of the router case or on the manufacturer’s website. On the router’s page, you need to find “Advanced Settings”, the “Wi-Fi and Network Settings” tab. You need to set the “Enable wireless connection” flag. If the flag is on, but for some reason the problem remains, then the last method is to change the channel on which the router is running. In order not to change the channel blindly, you can use the program “inSSIDer for Home”, which analyzes the frequency range of the channel. Channels 1 to 11 are the American standard for Wi-Fi, most devices can work on THESE channels. They can be free from 11 to 13. When changing the settings, do not forget to click “Save”.
You can try to remove encryption, the setting is called “Authentication Method”, change to “Open System “. The problem might be the length of the key (“WPA Preshared Key”). If it is more than 20 characters, then the router will stop working with such a long key. Most likely, the key can be NOT more than 12-13 characters. Here you can also update the firmware: section “Administration”, tab “Update firmware”.
Why are there still difficulties? The problem might be in the software. If you have System Restore enabled in Windows, then restore points will be shown in the log when installing programs. You can bring the operating system back to the day the network was up and let it see connections again. You need to select a state, click “Next”, follow the instructions. The Wi-Fi network can often disappear when updating the OS, so sometimes you have to reinstall programs after the update, including for a wireless connection, and then the computer again sees what it needs.
The laptop does not see the Wi-Fi network adapter. Network problems
If you have installed the drivers for the keyboard, turned on the Wi-Fi module, and you still have the Internet, then open the “Control Panel”. Select “Internet Networks” and in “Sharing Control” select “Changes to adapter settings.” Here you will see a list of all adapters. Click on “Wireless network”. If there is a gray icon and the inscription “Disabled”, then there is a Wi-Fi icon in the system tray, which is why nothing works. In this case, you need to enable: right-click the context menu and select “Enable”. The wireless network becomes active. If an error occurs, it helps to launch the “Diagnostics Windows Networks” The system itself can find and fix errors.
If after that the computer does not detect an available network, then reinstall the drivers for the wireless network adapter. Open “Device Manager”, click on “Network adapters”, find the desired device. You need to uninstall and reinstall the driver. Drivers can be found on the Official page of your computer manufacturer or you can find a CD with a working driver bundled with your computer. After installing the driver, you need to turn on the Wi-Fi module and see the work. if everything was activated, we figured out why the network disappeared.
Sometimes it happens that the laptop does not see the wireless network after being under repair or after cleaning. Masters can turn off the antennas. Then you need to disassemble the laptop case and connect them or seek help from specialists.
If all else fails and the computer still does not see the available networks, then there is a possibility that the Wi-Fi adapter could fail: it may burn out during operation, it needs good cooling. If it burned out, it will not be displayed in the “Device Manager”, this problem will be issued during “Diagnostics Windows”. It will need to be repaired or changed.
So, we have covered the most common sources of problems when a computer with Wi-Fi fails. Remember that any problem can be fixed by knowing its causes.
Windows 10 stopped seeing home Wi-Fi. try commands
If the network card is still NOT looking for a network, you can try the following commands on the command line.
Run it as administrator, enter the following command and confirm it with the Enter key:
- Netsh winsock reset catalog
When the command is executed, enter the following, this time it will be:
- Netsh int IP reset reset.Log hit
I also confirm it with the Enter button, and then wait for it to complete and restart the system. After restarting, we check if this method helped to solve the problem.
Computer or Laptop Can’t See Wi-Fi. Fix Disk Errors
This procedure can also help because errors may NOT start Wi-Fi auto-configuration service.
Similar to the third step, we are also invoking the command line in administrator mode and enter the command:
After confirmation, the system will check the disk and fix any errors. At the end, we restart the computer and check if the Wi-Fi network is working.
Windows 10 computer or laptop cannot see Wi-Fi network due to network card
As a result of interrupted or incomplete updates, as well as after using various types of programs that clean the computer, damage to the Windows 10 system may occur.
One of them is problems with the Wi-Fi network. the network card is working correctly, but it does not see any networks. What to do about it?
This issue can even occur due to system update issues. After starting your computer or laptop, you notice that we have an Internet connection, and the network icon is displayed crossed out in the system tray.
This means that the network card simply does not detect any networks nearby. Then you need to run diagnostics with network troubleshooting. To do this, right-click on the Wi-Fi icon (in the tray) and select “Troubleshoot”.
The solution to this problem can be very difficult. Sometimes you just need to re-enable a service called “Auto WLAN Configuration”.
Secondly, you will need to execute more complex commands, and may even end up with the need to restore the system to a previous point or perform a complete reinstallation.
Why Windows 10 PC or laptop can’t see Wi-Fi network
Network environment issues in Windows 10 is another error that appears in this version of Microsoft’s system.
After the latest updates, many Windows 10 computer / laptop users stopped seeing Wi-Fi.
This makes it difficult to connect to your home Wi-Fi network. Now we will try to solve this problem. How much you can decide for yourself.
In fact, this problem can occur Not only after updating Windows 10 to version 1511.
Problems with Wi-Fi networks also occur in earlier compilations of Microsoft systems and most often occurs on computers that have been upgraded to Windows 10 directly from Windows 8.1 or Windows 7.
This appearance is also much more common among people who actively use VPN connections on their PCs.
Wi-Fi problem in Windows 10 cannot be solved by restarting the computer or putting it in so-called safe mode.
You can wait for Microsoft to release another patch to fix bugs in the system, but it’s better to try to fix the bug yourself.
Of course, first of all, you definitely need to check the drivers. a bad driver does not see the network 100%.
If everything is in order with the Wi-Fi driver, then below are other ways to solve the problem of accessing Wi-Fi in Windows 10.
Windows 10 does not see my Wi-Fi router. return the system to the previous point
Windows creates so-called restore points at different times of computer or laptop use.
One of these points is the installation of updates, so that in the case of a user, users can return to the state of the computer before the updates were installed.
Bringing the system to an earlier point in time when the Wi-Fi network is working can restore the network adapter.
You can simply invoke the “Recovery Wizard” using the startup window. Press the combination “WindowsR” and then enter the following in the run window:
After pressing the “Enter” button, the system recovery wizard will appear. click “Next”, (put the checkbox as in the picture) select a restore point from the period in which the Wi-Fi network worked well.
You do not need to worry about your personal data. files are NOT deleted from the computer, only the system itself is restored, the data on the disk is safe. Wi-Fi should work properly after system restore.
If none of the above methods work, you may need to reinstall your system. Success.
What to do if a computer or laptop with windows does not see available Wi-Fi networks
First we need to run Command Timeline in Admin Mode. We can do this for example by Right-clicking on the Start icon on the Windows 10 taskbar.
Then from the drop-down menu select the command “Command Prompt (Admin)”.
After starting the command line in the program window, paste and confirm with the Enter command the following command:
And after it’s done, paste and Confirm another command:
- Netcfg.V.U dni_dne
After executing the above commands, if correctly received by Windows 10, the computer should be restarted.
After rebooting our PC, all available networks should be visible and accessible for Windows 10.
You can also use another solution that introduces similar changes. To do this, start PowerShell in administrator mode.
Then paste it in and Confirm with the following command:
- Get-AppXPackage.Allusers | Foreach
You must first close all applications, programs and documents that are open on your computer.
After running the command, restart your computer. Only at the beginning I recommend using the first method. using the command line.
If, however, none of the above methods work and you still have problems with Wi-Fi networks in Windows 10, try a few more methods.
Windows 10 computer or laptop does not see the Wi-Fi network. will start the WLAN service manually
Press the “WindowsR” button combination, and then in the start window enter:
Confirm the command with OK. In the new window with the list of services, look for the services named WLAN AutoConfiguration Service. Double-click Found Item to view details.
This service must be running and the startup mode is set to “Automatic”.
If the start mode is manual. Set it to automatic. Then click the “Start” button to enable the service.
If the service is running, networks should be discovered again. Unfortunately this is rarely fixed in such an easy way, so you may need to do the following.
Windows 10 PC or laptop can’t see Wi-Fi network. check registry for WLAN
Press the combination of the combination “WindowsR”, and then enter the following command. “Regedit” to launch the editor.
In the registry editor, we need to check the value of the entries for the three “Ndisuio” branches in the following paths:
- HKEY_LOCAL_MACHINE. SYSTEM. Controlset001. Services. Ndisuio
- HKEY_LOCAL_MACHINE. SYSTEM. Controlset002. Services. Ndisuio
- HKEY_LOCAL_MACHINE. SYSTEM. Currentcontrolset. Services. Ndisuio
So, first go to the Ndisuio key in the first path and mark it. On the right side of the registry window, the entries belonging to this key will be displayed. we are looking for the Start entry here.
Then double-click it to display the edit entry window. The “Value data” field will be displayed here.
Problems arise when the entry is set to a value other than “3”. If it has “2” or “4”, change it to “3” and save changes with OK.
We repeat the same for the second Ndisuio. At the end, we restart the computer / laptop and check if Windows 10 has started to see the Wi-Fi network.
Thanks! Your article helped solve the problem with the internet connection
If the WLAN autoconfiguration service could not be started, this may be due to the corruption of its dependencies, if you did not encounter error 1079. Therefore, in this solution, check the system integrity with the SFC utility.
Open the command term as an administrator using the system search.
Run the command in the console:
Wait for it to complete and restart your computer. Check if the network adapter sees shares over Wi-Fi.
Fix with command line injection
If the network adapter still does not see the network shares, try the following commands.
Type “cmd” in the system search box. When the command line appears in the search results, run it as administrator.
In the console, run the commands in turn, confirm each with Enter:
- Netsh winsock reset catalog
- Netsh int IP reset reset.Log
After successful completion, restart your computer.
Why the network adapter can’t see the network. what to do?
As a result of an interrupted update, as well as after using various cleaning programs, Windows may malfunction. In particular, you may encounter an error when connecting to Wi-Fi, when, when the network adapter is working correctly, it does not see the network.
This problem can be encountered, for example, when you turn off your computer while installing a system update. At the next boot, we find that there is no Internet connection, and in the system tray we see a crossed out network icon. The network adapter just doesn’t see any networks nearby, and only offers “troubleshooting”. In turn, the diagnostics displays the error “Windows Wireless Service is not running on this computer”.
Checking entries in the system registry
Open the Registry Editor with the regedit command from the Run window (Win R).
You need to check the value of the Start parameter in the three Ndisuio sections located along the path:
- HKEY_LOCAL_MACHINE. System. Controlset001. Services. Ndisuio
- HKEY_LOCAL_MACHINE. System. Controlset002. Services. Ndisuio
- HKEY_LOCAL_MACHINE. System. Currentcontrolset. Services. Ndisuio
Go to each section in turn and double-click on Start to open its properties. Network discovery problems occur when Start is set to a value other than “3”. If “2” or “4” is indicated, change it to “3” and save the changes to “OK”.
We repeat this action for the remaining sections. After restarting the computer, check if Windows can see the local network.
First try restarting the WLAN autoconfiguration service.
Open system services using the services.Msc command from the Run window (Win R).
In the list, find the service “WLAN Auto Config”, Right-click and select Properties.
The service must be started (state: Running) and the startup type is set to Automatic. If the startup type is set to “Manual”, Change it to automatic and click on the “Start” button.
Then see if the network adapter detects the local area network over Wi-Fi.
Before the occurrence of such events as system updates, driver installation and others, Windows automatically creates restore points (snapshots). They are provided in case of a failure, so that you can return the OS to a working state. Therefore, returning the system to the previous state in which the Wi-Fi network worked can restore the operation of the network card.
Calling the recovery wizard with the rstrui.Exe command from the Run window.
On the second screen, select the current that was created before the computer stopped seeing the network.
Confirm the start of the recovery by clicking on the “Finish” button, and wait for the process to complete. Check if the network adapter sees shares.
The case when the laptop does not see Wi-Fi networks at all
In such cases, when you turn it on, you DO NOT detect any wireless networks as such. IN “tray” (the space, which by default settings is in the lower right corner and is represented as a line with notes) instead of the connection icon, you will see a red cross. It is also possible that the icon will be standard, but the computer does not see Wi-Fi, and you are sure that there are wireless networks within the receiver’s radius (it is easy to check using a phone or other device with a Wi-Fi adapter). The difficulty is obvious, and in another case, you would have to call the wizard, but after reading this article it will be possible to solve such a problem yourself.
- Check your laptop for the presence of a mechanical button or a mode switch for the wireless adapter, and try to turn it on (there are times when people accidentally cling to an invisible toggle switch, and are 100% sure that nothing of the kind happened from the laptop). You can also try the Fn keyboard shortcut “wifi network icon button”
- It is not difficult to check whether the driver is installed correctly, there is an instruction.
- Click on “My computer” right-click and press “properties”.
- Next, in the upper left corner of the submenu that opens, click on “device Manager”.
- And if you have difficulties, then you will see a yellow triangle, signaling the absence of a network card driver, for this reason your computer does not see the Wi-Fi network (if there are such triangles in the column, it means that the drivers are installed correctly).
- Reinstall the drivers according to the instructions of the manufacturer of the network card. This instruction is in the box left after purchase, but if, for some reason, the box and instructions are NOT saved, this information can be easily found on the Internet.
Troubleshooting Wi-Fi network connection problems on laptops
All laptop owners may sooner or later face the fact that the laptop does not see Wi-Fi. The complexity is widespread in principle, and some of the solutions will help any wireless network user. The article will give a full answer to the question of what to do if the laptop does not see the Wi-Fi network. Consider what causes can lead to such consequences, how to deal with the difficulty of auto products and the nuances of elimination on various platforms.
- The most common reason why a laptop does not see Wi-Fi is that the laptop’s wireless adapter is turned off. Often it is accidentally turned off manually, although there are times when this happens due to the fault of the installed software. It can be disabled by system, by a combination of buttons on the keyboard or in the wireless networks menu. It is also possible to physically disconnect via a button on the laptop case.
- A possible prerequisite for the complexity is the absence or incorrect installation of the network card drivers, when installing the wrong software version (Software) for the network card, or installation failure.
- The reason that the laptop stopped seeing the network is the absence of active wireless networks within the range of the device.
The case when the laptop does not see a specific network
The difficulty when your laptop does not see Wi-Fi is also solved. Let’s say the device does NOT find the router’s network, but sees signals from a neighboring office or building without difficulty. This difficulty is puzzling, especially if you look for a solution in a laptop (the fault is not always in the computer, sometimes it does not catch Wi-Fi due to third-party reasons).
The reason that the laptop does not find a specific network is very often (in about 85% of cases) one. Due to the fact that wireless networks have entered our life very densely, often in large cities there are about 10 routers distributing Internet for one reception signal. Each new access point that appears looks for a free range. In the settings of wireless networks, for the most part, automatic range search is set. When you turn on the laptop, it does not find Wi-Fi later, which accidentally tuned in to the range of a nearby Wi-Fi connection.
