The problem cannot be connected to this network. Wi-fi on the laptop does not connect. Error: Windows could not connect to wifi. Disable active VPNs
Hello dear friends. As you probably already understood from the title, today I decided to touch on a very serious and painful topic, and try to figure out what to do when Wi-Fi does not work on a laptop or netbook and how to still connect a laptop to a Wi-Fi router. By the way, it can be not only a laptop or a netbook, it can also be an ordinary stationary computer with a Wi-Fi receiver. There have been a lot of similar questions lately, mainly to the article.
Now we will try to figure out step by step what and why problems may appear when connecting a laptop to a wireless Wi-Fi network. We will also try to find a solution to this very popular and unpleasant problem with connecting to Wi-Fi, or rather a failed connection.
Most often, problems arise when the Wi-Fi module itself on a laptop cannot be turned on. And when Wi-Fi turns on, the laptop finds all available networks, but when trying to connect, it writes. It is necessary to check whether the drivers are installed on the Wi-Fi adapter, whether Wi-Fi is enabled on the laptop, etc. Now we will do this.
I noticed that most often problems with connecting to Wi-Fi are found in Windows 7. It is on this OS that the network without Internet access error very often appears, I wrote how to solve this problem in the article, the link to which is above. In fact, as practice shows, there can be a lot of reasons for this problem. And if there are many reasons, then there are many ways in which you can force a laptop to connect to a Wi-Fi router.
But it is not always the laptop, netbook, etc. that are to blame. There may be a problem in the access point, that is, in the Wi-Fi router. And the first thing we need to do when there is a problem with connecting to Wi-Fi is to determine what is the reason, in a laptop, or in a Wi-Fi router. Now I will consider the problem with connecting to my own router. Because if you are unable to establish a connection with someone else's Wi-Fi, then all claims to your neighbor, it is most likely that he has problems :).
Who is to blame, laptop or Wi-Fi router?
As I wrote above, you first need to find the culprit. Before making any settings on a laptop or a Wi-Fi router, you need to understand what the problem is, which is why it is impossible to connect the laptop to Wi-Fi. You can just set it up so that you have to do it and set everything up again. The best way to determine which device is hiding the problem is to try to connect another device to the router, for example, another laptop, tablet, or phone. And a laptop that has problems connecting to Wi-Fi should try to connect to a different wireless network.
I think you understand my idea. If other devices are connected to your router (best with a similar operating system) will connect without problems, then the problem is in the laptop. Read this article further, now let's try to solve.
Well, if problems with connecting to your network arise on other devices, and the “problem” laptop connects to other networks without any problems, then the problem is in setting up the Wi-Fi router. See article on, it might come in handy.
I will show on the example of a laptop that runs on Windows 7. This is by far the most popular operating system.
I advise you to immediately pay attention to the icon that displays the status of the Internet connection. It's in the notification bar.
If your internet connection status looks like this:
First, you need to check if the drivers are installed on Wi-Fi and if the Wi-Fi adapter is enabled.
Right click on "My computer" and select "Properties". On the left select "Device Manager".
In the new window open the tab "Network adapters" and see if there is a device like Wireless Network Adapter (you may call it differently)... If you have such a device, then right-click on it and select “Properties”. Another window will open, make sure it says "The device is working properly."
If everything is about the same as mine above in the screenshot, then everything is fine, the driver is installed. And if there is no Wireless Network Adapter and you have unidentified devices, go to the website of your laptop manufacturer, download and install the driver for the Wireless Network Adapter for your model.
For details on installing and updating the driver for your wireless adapter -.
We figured out the drivers.
Check if Wi-Fi is enabled on the laptop
If the driver is installed, but the Wi-Fi module is disabled, then the connection status will be the same:
Usually the wireless adapter on the laptop is turned on, but it doesn't hurt to check. Wi-Fi on laptops (netbooks) is usually enabled and disabled by a keyboard shortcut. On my ASUS K56cm, these are the keys FN + F2... But although when I press these keys, I get a message that the wireless adapters are enabled / disabled, but nothing happens. Look for the key on your laptop FN and key with a picture of a wireless network... Press them at the same time.
Some laptops may have a dedicated switch on the case that can be used to turn Wi-Fi on or off. For example on Toshiba Satellite L300 it looks like this:
Turn on or off the Wi-Fi wireless adapter in Windows 7
But the best way to check if the wireless adapter is working or not is to go to the Network Control Center and see.
So on the notification panel, right-click on the Internet connection status icon and select "Network and Sharing Center".
Then select on the left.
Among the connections we are looking for "Wireless network connection"... If everything is fine and the Wi-Fi adapter is on, then it should look like this:
If the adapter is disabled, it will look like the screenshot below. Right click on it and select “Enable”.
Using the methods described above, we must make it so that the status of the Internet connection on the notification panel is like this:
This status means "No connection - There are connections available" - this means that the Wi-Fi adapter is turned on and there are available wireless networks for connection.
If the connection status is like this:
This means that Wi-Fi is on, but the laptop simply does not see the networks available for connection.
Error "Windows could not connect to ..."
We figured out the problem when the wireless network module is disabled or does not work at all. Now let's consider the case when the laptop finds available Wi-Fi networks, but when trying to connect to Wi-Fi it writes: "Windows could not connect to ...", where instead of dots the name of the network to which you want to connect.
If you have a network connection status such as in the screenshot above (through one, network with a yellow icon), then click on it and you will see a list of networks available for connection.
Select the required network, click on it, then click the "Connect" button.
If the set is password protected, Windows will ask you for the password. Write down the password for the network and click "OK".
And if everything is fine, then your laptop should connect to the Internet wirelessly. And the status of the Internet connection should look like this:
But exactly at the moment of connection, the error “Windows could not connect to ...” very often appears. It looks like this:
Sorry friends, there is no definite solution to this problem. But I can download that very often the problem with such an error appears due to the settings of the Wi-Fi router. Maybe through the type of security and encryption that is installed on the Wi-Fi router, read more about this in the article. There may also be a problem with the distribution of IP addresses.
If you have noticed, then in the window with the error “Windows could not connect to ...” it is possible to run "Troubleshooting", it is a sin not to use it. Try to run, I heard somewhere that there are cases in which it helps :). But seriously, sometimes it really helps. Windows will check the readiness of the wireless adapter, check the settings, etc. And if it can, it will fix the problem that prevents you from connecting to Wi-Fi.
Just restart your router and then your laptop. It often helps.
Update
I noticed that in Windows this error appears when the settings that are saved on the computer for your network do not match the current network settings. I'll explain now.
For example, your laptop was connected to Wi-Fi, it automatically connected to the network. But you took and changed the password, or the type of network encryption. Now the laptop is trying to connect to the network, but the parameters do not match anymore, that's the error.
Enough, just delete the network on the computer and re-establish the connection. I wrote about this in the article
Conclusion
It's a great article, and I hope it's useful. I wrote it for half a day, with breaks, of course, there were still problems with adding screenshots to the site, but I seemed to have solved it.
I tried to collect all the necessary information that should help you solve the problem that occurs when connecting a laptop or netbook to Wi-Fi. If I forgot to write something, then in the future I will definitely supplement the article, I will also be very grateful if you share information in the comments that helped you solve the problem with connecting to a wireless network.
If you have any questions, then ask them in the comments, we will try to figure it out. Good luck!
Before proceeding to find out why Wi-Fi or the Internet does not work, you should know (especially for those who have just purchased a Wi-Fi router) that it is not enough just to connect the provider's cable to the router, it still needs to be configured (set up the Internet and Wi-Fi network ). All the methods described below are valid if Wi-Fi and the Internet worked for you before, and then suddenly stopped or you cannot connect a new device to Wi-Fi. For convenience, I have divided the article into two parts, the first is about the inability to connect to a wireless network, the second part will answer your questions if you are connected to a Wi-Fi network, but there is no Internet.
Unable to connect to Wi-Fi network.
Reboot the router.
The first thing to do if you have problems connecting to a Wi-Fi network is to restart the router. To do this, simply disconnect the power supply from the router and reconnect it after a few seconds. After 1-2 minutes. the device will boot, then try connecting to the wireless network again. In order to avoid such situations in the future, I recommend updating the firmware of the router (perhaps the manufacturer knows about the problem and has fixed it in the new firmware).
Enabling Wi-Fi module on the laptop.
Check if Wi-Fi is turned on on the laptop, I will not turn, I described all the ways to turn on Wi-Fi in the article How to turn on Wi-Fi on a laptop .
Change the wireless network mode.
If you are trying to connect a device (laptop, smartphone) that is more than 5-7 years old, you must take into account that it may not support the modern Wi-Fi mode - n... Therefore, you need to switch the router to an operating mode that is supported by the device or enable mixed mode b / g / n... More details about the modes of Wi-Fi are described. In order to switch the wireless network mode, you need to go to the web interface of the router, go to the Wi-Fi settings and select the appropriate mode.
Deletes the duplicated SSID.
One of the possible problems of not being able to connect to Wi-Fi is duplication of the Wi-Fi network name (SSID). Suppose you come to friends, their Wi-Fi network is called "Home", you have successfully connected to it. Time passed and already at other acquaintances or at home you met the same name of the network. A laptop (this also applies to tablets, smartphones) tries to connect to the network using the previously saved password, but it fails because a new password is used for this name. To solve this problem, you must delete the matching network from the list of saved Wi-Fi networks.
To do this, right-click on network icon in the lower right corner of the screen and select "Network and Sharing Center."
After that, you will see a list of saved wireless networks. If you see that the network to which you are trying to connect is in this list, you must remove it from this list. Select the network and click the "Delete" button. After that, you will need to enter a password to connect to the wireless network.
No internet on Wi-Fi.
Internet payment check.
The simplest thing that can happen when the Internet is not working is the time to pay for it or work is underway with the provider. To clarify the situation, call the provider and ask if you have any debts for the Internet and if any work is underway on the line.
Static IP address.
One of the problems is not the work of the Internet, maybe - the registered static address is not with the network settings that are necessary. In this case, I recommend using automatic acquisition of network settings. To do this, you need to go to the Network and Sharing Center. One way to do this is to right-click on network icon in the lower right corner of the screen and select "Network and Sharing Center."
Another way is to use hot keys
No matter which of the methods you used, the result will be one - the Network Connections window will appear on the monitor. Next, you need to click on the wireless connection with two mouse clicks, In the status window that opens, select "Properties" in the properties window "Internet Protocol version 4 (TCP / IPv4)"
Router problem.
The Internet may not work due to a router failure, the simplest thing to do is to reboot it. There are situations when the router resets the Internet settings, in which case you need to connect to it via the web interface and re-enter the Internet settings, in order to experience fewer problems with the router in the future, I recommend updating its firmware.
Conclusion
In this article, I described all the ways I know to solve problems with Wi-Fi and the Internet. If these methods did not help you, you can describe the problem in detail in the comments and I, together with the readers of this site, will try to help you.
Hello, now we will analyze the difficulties of connecting to Wi-Fi.
1. Cannot connect to the network after changing the wireless settings.
This error may appear after changing the password for the Wi-Fi network or resetting the router to factory settings. In this case, you need to remove the network from the list of saved networks on the device, and then reconnect to the network. For this you need:
Windows 7
Click on the internet sign with the right mouse button.
In the window that opens, select Network and Sharing Center.
In the network control center, select Management of wireless networks.
In this window, find your network, right-click on it and select Delete network.
Windows 8, 8.1
Click on the internet sign with the left mouse button.
Find your network in the list and right-click on it and select Forget this web. After that, select your network, press the connection, enter the password. If the password is correct, the network will connect.
Windows 10
Open the menu "Start"
Please select "Parameters"
Please select "Network and Internet"
Please select "Wi-Fi", then "Managing Famous Networks"
In the list that opens, select your network, and click Forget. Then connect to your network.
Android
If the phone cannot connect to your network and does not ask for a password when trying to connect, you need to delete the network and reconnect to it.
Go to Settings
And choose to forget or delete the network.
2. The Wi-Fi adapter on the laptop is turned off by software, or the drivers are not installed.
The most basic sign of this is the red cross on the Wi-Fi icon.
To check the adapter, right-click on the Wi-Fi sign and select Network and Sharing Center, and then in a new window Change adapter settings.
Looking in the window Wireless network connection and look at the status of the adapter, if the adapter is disabled, then right-click on it and Enable.
If this window is missing Wireless connection - on the badge This computer right click and select Control.
Please select Device Manager.
Please select Act, then Update hardware configuration.
If after the actions taken in network connections Wireless connection does not appear - you need to reinstall the driver on the wireless adapter. You can download the driver from the official website of your computer manufacturer. For help, you can contact the service center of your computer manufacturer.
3. Wi-Fi adapter is physically disabled.
If adapter state "Included", or you turned it on, but still there is a red cross on the connection icon, then the adapter is physically turned off.
If you use a key combination to turn on Wi-Fi in a laptop, then simultaneously press the Fn button, and the second button on which an antenna or a computer with a signal is drawn (these characters should be located on the F1-F12 buttons)
Also, the adapter can be turned off by the switch on the case, or by the button responsible for the adapter operation.
The switch position should be ON or the Wi-Fi icon should be lit.
Wi-Fi - this is the technology with which a very large part of apartments, cafes, restaurants, vehicles and many other social places are equipped today. And strangely enough, now every second person uses this technology using smartphones, tablets and laptops. I remember earlier, I had just a simple PC with a huge monitor and the Internet connected via a telephone line, then I even thought that soon such a thing as Wi-Fi would appear, and that all other digital technologies, will also develop at an incredible rate.
I think you have already guessed that now I will talk about Wi-Fi again. If we go deeper into the specifics, we will talk about why WIFi might not work on a laptop, as well as how to properly connect a laptop to Wi-Fi and what to do if an error appears " Windows could not connect to the network».
Why did I choose this particular theme? In fact, everything is logical, look, those who have Wi-Fi at home, as a rule, use it with a laptop, and such users are now the predominant number. And it so happened that when trying to connect to WI-Fi through a laptop, not everything goes so smoothly, various errors begin to appear or the network cannot be found at all. That is why, I decided to describe the situations why Wi-Fi may not work on a laptop and the reasons for the appearance of such an error as: "Windows could not connect to the network."
So right now, we will together analyze every reason that could cause problems when connecting a laptop to everyone's favorite Internet via Wi-Fi. And let's try to find a solution to the most popular problems due to which Wi-Fi may not work on a laptop or an error like "Windows could not connect to the network" appears.
I want to note right away that a laptop or computer that was connected via a Wi-FI adapter is not always the reason for the lack of a Wi-Fi connection. Sometimes, the reason may be the router itself due to incorrect settings during its installation, or there may be no direct signal from the provider, and we foolishly will sin on the laptop.
Therefore, so as not to waste invaluable time, we will start with diagnosing and determining what is the direct cause of the lack of Wi-Fi when connected to it using a laptop. I will give all examples on, but since all new systems are very similar to each other, you can easily find the item or parameter you need and the rest of the OS.
Diagnostics of the cause of the loss of Wi-Fi signal
In any diagnosis, there is no time to make hasty conclusions, I understood this from my own experience and having checked everything on my own skin. Sometimes, the cause of a malfunction or the appearance of an error may lie in some trifle or in tuning to which you would never even have thought, as a result, spending a huge amount of time looking for the wrong reason. The same applies to the Internet, before you take out a Wi-Fi router or laptop and make any changes to their settings, you should find out exactly who is to blame for the router or laptop. And now we change the settings so that then we will have to reset them back to the factory state and configure the router again.
The very first option would be to check the Internet using a direct cable connection from the provider to your computer or laptop. If the network connection icon lights up as usual without any warning signs, then everything is OK from the provider's side.
Then, connecting the cable back to the router, we try to access the Wi-Fi using some other device, such as a smartphone, tablet or game console. If, after connecting, the Internet icon is displayed normally and various pages open in the browser, then everything is fine with the Wi-Fi configuration.
Having made such quite simple manipulations, you can determine that the reasons for the not working wi-fi signal are located directly in the laptop itself
Note: If the Internet is absent on absolutely all devices, then the problem is clearly in the router itself or in its settings.
Enabling the laptop Wi-Fi adapter
Of course, first we check whether the wireless signal module itself is physically turned on or not, it is possible that Wi-Fi does not work on the laptop precisely because of it. Although it is almost always enabled by default, it is still worth checking, since you could have disabled it on purpose or did it inadvertently, or maybe some virus or an incomprehensible program that saves battery power on a laptop tried instead of you.
Usually, on all laptop computers, Wi-Fi is displayed in the form of an antenna, and is located mainly in the area of \u200b\u200bthe key family " F1 ... ... F12". Slightly below in the screenshot in which I show an example, it is located on " F3". But there is one moment, to turn on the adapter, just pressing F3 is not enough, to use minor commands ( What is the button for activating the WI-Fi module), you should press one more auxiliary key on which is written “ Fn».
That is, to turn on Wi-Fi, hold down the " Fn"And then the button" F3 " (Example) where I had a network icon displayed ( Your key may differ, pay attention to this).
Reboot the network and laptop
Another problem due to which it is impossible to connect to WI-Fi from a laptop is network sticking. Yes, yes, very often I met this even on my home network. It seems that everything is there, all devices are connected, but not your laptop.
In such a problem, I am often helped by restarting the router by disconnecting the power supply cable and then restarting the computer. And only after all this, the laptop starts to normally pick up the signal from the Wi-Fi router.
But the most interesting thing is that after rebooting only a laptop or a box with Wi-Fi, nothing happens to the Internet, you need to do this with both that and that, in turn, first the router, then the laptop. Be sure to try it, perhaps like me, this method will help you.
Check if the WI-Fi adapter driver has failed
This kind of problem is most often encountered when buying a new laptop or after. There are a lot of users who do not even know about such a thing as a driver and do not know how it works, in fact, they should not know this, because it is not their concern. But, because of the cheeky wizard who installed Winodws or because of the store in which the laptop was sold. with clean Windows, it so happens that there is no necessary driver, and if there is a driver for the network, then only for the LAN adapter, and the WI-Fi module is missing.
In general, the reasons for the loss may be different, so let me show you how to check if all network drivers are installed or not. In principle, everything is as easy as shelling pears, go to “ Network and Sharing Center", Which you can find in" Control panels", And there we click on" Change adapter settings».
A list of adapters that are installed on the laptop should open, if you do not find there such as "Wireless network connection", it means that you do not have a driver and the reason for the non-working state of the WI-Fi on the laptop is it, so for full work you will have to reinstall the driver on the Wi-Fi adapter.
Otherwise, if there is such a connection, as shown below for me, then the driver is installed, and everything should work fine, without any problems.
Restarting the wireless adapter
Without leaving the adapter settings, call the context menu by clicking on the wireless network and select " Disable».
Well, and then again, calling the same menu, click on " Enable", Than start the work of" BS "back.
Having done these manipulations, a yellow star should appear on the WI-Fi icon, indicating that Wi-Fi is not connected, but there are networks available for connection in the list. If you have already been connected to the network before, then most likely the connection will simply be restored and a normal, clean signal level icon will appear, without any signs about the absence of a network, etc.
And finally, let's talk about the error, "". This error is one of those that very often occurs when working with Wi-Fi and is one of the most annoying, because the reasons for its appearance are not clear and its solution every time may not be at all commonplace.
After what does it appear? By clicking on the WI-FI connection icon, a list of available networks will appear, where, having selected the position you need, you click on the " Connect».
Everything seems to be fine, you have been asked for a router. By clicking " OK", must start connection.
But in a friend, instead of connecting, a window appears with the words that "Windows could not connect to this network." I am sure that when the appearance of this problem again, you tried to establish a Wi-Fi connection again, but this attempt was also unsuccessful.
Usually, the reason for this error is the Wi-Fi router settings themselves, for example, an incorrectly set security type, where there is one on the router, and you are trying to connect differently. Be careful when choosing encryption, I think if you configured the router yourself, you know what you installed, the rest most likely have the type " wpa2-psk”Which is used in almost every WI-Fi network today. Check if it was security that caused the "Windows could not connect to this network" error.
Sometimes, again, I repeat, sometimes, restarting the Wi-Fi router and device helps, I mentioned this just above. But this is not a boilerplate solution that will definitely help. If you have already encountered such an error, simply and then, using our instructions,.
After such a radical step, the error "Windows could not connect to this network" should no longer bother you.
I'll end there. I seem to have remembered everything that helped me in solving problems such as wi-Fi not working on laptop and the errors "Windows could not connect to this network." Perhaps you managed to overcome these faults in your own way, then do not be greedy, leave it in the comments and I will 100% add it to the article, as an addition, so that everyone can find something that suits him or helps.
WI-Fi does not work on the laptop. Error: Windows could not connect to this network
Very often, when connecting to a wireless network, users encounter various errors. Probably the most common is that Windows was unable to connect to the WiFi network. What is this error and how can I fix it? This is what will be discussed.
But before moving on to connection problems and solutions, first a few words about how a wireless network works. The fact is that WiFi routers are usually used to create private groups. It is to them that the computer is subsequently connected. This means that first of all, if you have any problems with the connection, you need to check the access point (router).
Why Windows can't connect to WiFi network
There are more than enough reasons for such an error. It is simply impossible to consider each of them. Therefore, let's take a look at the most common problems with connecting to a WiFi network and their solutions. So, if the computer sees the network, but cannot connect to it, then the following parameters should be checked:
- Checking if the network key was entered correctly.
- Router settings.
- Driver check.
- Wireless settings in Windows.
- Firewall and antivirus settings.
There may also be software and driver conflicts, and even a malfunction of the wireless adapter. Let's go in order.
Checking the network key
Very often the reason for the connection error is a mismatch in the password. This means that you simply made a mistake when entering the key. Therefore, first of all, you should check the correctness of writing the code. Try reconnecting to the network, but carefully check the keyboard layout and if Capslock is enabled.
How to find out the password for your WiFi in the router parameters: Video
Configuring the router
If you are still sure of the correctness of the entered key, then it is worth checking the settings of the router. To do this, connect to it with a cable. Next, open your favorite browser and write the IP of the router in the address bar. It is indicated on the bottom of the device, as well as in the instructions (if any).
How to easily find out the IP address of a WiFi router: Video
Now we need to enter a password and login. Initially, these are admin, admin, respectively. If you have already changed this data, then enter your values. After that, go to the settings menu. Everything is simple here. We are interested in setting up a wireless network (Wi-Fi). Find the Security Settings. Find the network key in the security settings. You can change it if necessary.
Next, you should check the MAC address filter. It is possible that you, or someone else who has access to the router (the possibility of hacking is possible), entered your computer into the filter by MAC address. Because of this, even with the correct password, you will not be able to connect to the WiFi network.
To check this, you need to go to the "MAC-Filtering" item in the wireless network settings and check if there are any devices there. You do not need to find out the MAC address of your computer, you just need to remove all devices available there from the list.
How to set up a MAC filter in a router: Video
It is also recommended to reboot the router as they may malfunction. This applies to absolutely all models, from the budget ones to the most expensive ones. If you have done all the above steps, and Windows still failed to connect to the WiFi network, then go to the operating system settings.
Driver check
First of all, you need to check for the presence of drivers and their correctness. The fact is that any version of Windows needs hardware software, since a special program is needed for a particular module to work. The operation of the equipment (in our case, the wireless module) also depends on the correctness of its operation.
So, you can check this in the task manager. You can open this service in any version of Windows through the properties of my computer. Find "My Computer" on the desktop or in the start menu, right-click on it and select "Properties". In the window that appears in the left menu, we find the "Device Manager". Now we need to find a branch called "Network adapters" and open it.
If there is no such branch, then it means that there are no drivers for network cards. In this case, you need to install them. But if you can turn on the WiFi module, and the computer sees available networks, but it cannot connect to them, then the drivers must be installed. The only question is the correctness of their work. So, let's open the network adapters branch. It must have at least two devices:
- Network adapter.
- Wireless Network Adapter.
In addition, there may be Bluetooth devices and other network modules. If the wireless adapter is highlighted with an exclamation mark, it means that the drivers are not working properly. There may be other problems as well. You can find out the error by right-clicking on the module and selecting "Properties".
In the window that appears, in the "General" tab (as a rule, it opens first) you will find the item "Device status". The error and its number will be indicated here (if the device is not working properly). Knowing the error, you can find a way to fix it. As a rule, reinstalling the driver solves all problems.
Reinstalling the driver is very easy. It is available on the disc that came with the laptop. But even if there is no such disk, then you can download them on the official website of the laptop manufacturer. After downloading and installing, check their software operation as above and try to connect to your network.
How to Reinstall WiFi Driver: Video
Configuring a Wireless Connection in Windows Management Console
First of all, we need to open the Network and Sharing Center. It is this tool that allows you to manage all network connections, including wireless ones. This can be done in several ways, but we will consider the simplest one.
Find the network icon in the tray (lower right corner), right-click on it and select the "Network and Sharing Center" item. In the window that appears, first of all, we are interested in the item "Change adapter parameters". Now we are in a service that allows you to manage connections. We find the shortcut "Wireless network". Click on it with the right mouse button and select "Properties".
In the window that appears, in the "Network" tab, you need to find the Internet protocol version 4 TCPIPv4. Select it and click "Properties". In the menu that appears, check the box “Obtain an IP address automatically”. A little below it is also worth setting a marker on automatic data acquisition. Click "OK", close the window and try to connect to the network.
If Windows still cannot connect to the network, then return to the control center and select the "Manage wireless networks" item. Find the required network in the list and click "Adapter Properties". Next, we check the TCPIPv4 protocol, as described above. Trying to connect again.
If the problem persists, enter the "Manage wireless networks" menu, find and delete the required network. Don't worry, Windows will find it anyway. This is necessary to reset all connection parameters.
System diagnostics
If you have followed all the above steps, and the system still gives an error and Windows could not connect to the WiFi network, then you need to run diagnostics. There are several ways to enable it. It should be noted that in case of any errors, as a rule, the system itself offers diagnostics. But if, nevertheless, this did not happen, then the fastest way to start it is to right-click on the network icon in the tray and select "Troubleshoot".
After that, the system will automatically start searching and eliminating errors. You just have to follow the prompts on the screen. It should be noted that such diagnostics can be performed several times in a row, since Windows does not always find and fix the error the first time.
We've covered the most common errors that you can fix yourself. However, there are also more serious mistakes that require an individual approach. All records of problems and crashes are contained in the Windows log. If necessary, you can view it and find out the error code associated with the wireless connection. This will help you find a solution faster.
How to view the Windows event log
On all operating systems, this log is in one place. In order to open it you need to find the shortcut "My Computer". It can be on the desktop, in the start menu, or in the file manager. Click on it with the right mouse button and select the "Management" item.
In the window that appears in the left menu, we find the "Event Viewer". Open it and find the "Windows Logs" folder. We open it. Now we find the item "System". This is the required log. We open it. When opening, you will need to wait a little, since the system has a huge number of records, which take some time to scan.
In this log, warnings are marked with yellow triangles with exclamation marks inside, and errors are marked with red circles. Now all that remains is to find an error in the list related to the Internet connection or local networks, and open it by double-clicking it with the left mouse button. In the window that appears, you will see all the information about the error, as well as its code, by which you can find a solution to the problem on the Internet.
