The laptop does not connect to the Internet via wifi. Why doesn't my laptop connect to WiFi?

Facebook

The most common problem among Internet connections and Wi-Fi networks is when the laptop does not connect to the Wi-Fi network through the router. We have a lot of questions on our website on this very topic, and they often ask what to do if the laptop doesn’t want to connect to the Internet via Wi-Fi? I decided to write a separate article in which to collect everything possible reasons and their solutions related to connecting to Wi-Fi networks.

We will look at laptops and computers with Wi-Fi adapter ami. Simply put, any computer that can connect to the Internet wirelessly. Also, this article is suitable for Windows 7, Windows 8, and Windows 10. We already have many separate instructions on our website, with different solutions, specific problems with Wi-Fi on both Windows 7 and Windows 10 laptops. As I write this article, I will provide links that you will definitely find useful.

In the question itself, “what to do if the laptop does not connect to Wi-Fi,” there is no specific information at all. There can be many reasons why you cannot connect your computer to the router, as well as solutions. And as practice shows, the computer is not always to blame. I will try to consider all possible problems in order, so that you yourself can fix them without any problems. Of course, everyone different laptops, different routers, settings, problems, errors, etc. This undoubtedly complicates the task; it is very difficult to prepare universal instructions that would help absolutely everyone.

If you have a laptop with installed Windows, There is Wi-Fi router, which is distributed by the network, and you just can’t connect your laptop to the Internet via a wireless network, you can’t figure out what’s what, then this article should help you.

Before we move on to any settings, be sure to try connecting your laptop to a Wi-Fi network using. If you have Windows 10, then see. Perhaps you will succeed. If the problem remains, Wi-Fi computer connection failed, then see the article further.

I would divide all problems with Internet connection and operation into three categories:

The laptop does not see the Wi-Fi network at all: the wireless adapter is turned off, the driver is not installed.
The computer sees the Wi-Fi network, but does not connect to it: incorrect password, “failed to connect,” endless connection, etc.
The laptop connects to the wireless network, but the Internet does not work: “No Internet access”, “Limited”.

You can go straight to to the required section, depending on what problem you have. Whatever it is, it must definitely fall into one of the categories. It will be much simpler and clearer this way.

What to do if the laptop does not see the Wi-Fi network?

And so, let's start with the problem when your computer does not see wireless networks at all. At the same time, you are absolutely sure that your Wi-Fi network is working, there is neighboring networks, and they appear on other devices. But on the list available networks on Windows they don't exist. And there is no list itself. In this case, the connection status (icon on the taskbar), most likely it will look like this:

If in the notification panel you see a wireless network icon with a red cross "no" available connections", then most likely there really is not a single wireless network within the radius. But it is possible that this problem appeared for other reasons. In this case, running "Problem Diagnostics" may help. (you can start by clicking right click mouse on the connection icon). Wrote about this on Windows example 10, in the article.

Most likely, you have the first case. Red cross near the computer. In this case, the driver for the Wi-Fi adapter is not installed. Or, the wireless adapter itself is turned off. Let's first make sure that everything is in order with the driver, since without it nothing will definitely work.

Checking the wireless adapter driver

To do this, we need to go to the device manager. Right-click on “Computer” or “This PC” and select Properties. In a new window, on the left, open device Manager. You can also go to the start menu and start writing “device manager” in the search and open it in the search results.

In Device Manager we need to open the tab Network adapters , and see if there is a driver for our wireless adapter there. You will recognize it by these words in the name: “Wireless” and “Wi-Fi”. This is roughly what it looks like:

If everything is in order there, then read this article further. If the driver for the Wi-Fi adapter is not in the device manager, then you need to install it, and everything will work. If you don’t know how to install the driver, where to download it, etc., then see the article on. On Windows 8 or Windows 10, this process will be virtually no different.

The main thing is to download and install the driver specifically for your laptop model (or the adapter itself if you have a USB/PCI adapter), and for yours operating system. Well, I recommend downloading the driver from the official websites of the manufacturers. If it doesn’t work out at all, then you can try programs for automatic installation drivers. But that's if you can't find it required driver and install manually.

Checking if the wireless adapter is turned on

The adapter itself, through which the laptop connects to Wi-Fi, or rather in our case does not connect, can be turned off. This needs to be checked. Right-click on the Internet connection icon and select "Network Control Center and shared access" . In the new window, select Change adapter settings.

There must be a wireless adapter network connection, or Wireless network - in Windows 10. If such an adapter is not there at all, then see above where I wrote about installing the driver. If it is, then perhaps it is turned off. Right click on it and select Turn on.

If it is enabled, then you need to check whether the wireless connections on the laptop itself are disabled. On every laptop, there is a keyboard shortcut that can be used to turn off/on wireless connections (activate airplane mode), including Wi-Fi. This, as I already wrote, is either a key combination or some kind of separate switch. For example, on Asus laptops, these are the Fn+F2 keys. You can always find this combination yourself. Key Fn+antenna key, Or something like that. You can view separate instructions By . And if you have Windows 10, then see these instructions

So we’ve sorted out the problems that prevent us from connecting to Wi-Fi. When the list of networks available for connection is not displayed. If you've tried everything, but you can't get your computer to see wireless networks, then it is possible that the adapter itself (hardware) is simply broken or disabled. This, by the way, often happens after disassembling a laptop and cleaning it from dust. You can describe your problem in detail in the comments, I will try to advise something.

Computer won't connect to Wi-Fi

According to plan, second a big problem this is when the laptop sees and displays a list of available networks, your network is there, but it does not connect to it. At the same time, other devices connect to your network (it would be good to check and make sure of this). Let's now look at the most popular problems with connecting to Wi-Fi in Windows 7 and Windows 10. On the eight, everything is the same, there is nothing new there.

First of all, if any error appears, reboot your router and computer. Try connecting again.

Error: "Windows could not connect to..." and "Cannot connect to this network"

A very popular error that may appear when trying to connect a laptop to a Wi-Fi router.

I wrote about solving this error in Windows 10. As for Windows 7, the solutions are the same. To be honest, there are not many solutions there, the error is not very clear, and there is no specific way to get rid of it.

What else can you try to do: check on the laptop, in properties Wireless network connection (protocol version TCP/IPv4) is it displayed there? automatic receipt IP addresses. In the router settings, you can try changing the security type of your network to WPA2-PSK (if you have another one installed). All this can be done in the router settings. We have it on our website detailed instructions to change the password on different routers.

There is a solution to the error “Windows could not connect to...” in Windows 7.

Security key mismatch. Windows does not accept Wi-Fi network password

You select your network from the list, specify the password, and Windows writes that the password is incorrect. Well, of course, the computer does not connect to Wi-Fi.

Try again, maybe you really entered the wrong security key. Check if CapsLock is enabled. If the laptop does not want to accept your password, then there are two options: remember the password by looking at it in the router settings, or change the password for your wireless network. See article: . You can change the password, for example, to some simple number. To check, then set a more complex password.

Read more about this error and its solution.

Another error that often appears in Windows when trying to connect to a wireless network. And it usually appears after changing some settings on the router. Basically, this is the network name and password.

When the error “The network settings saved on this computer do not meet the requirements of this network” appears, it always helps Wi-Fi removal network on the computer, and reconnection. I gave links to instructions for deleting a network in Windows 7 and Windows 10 (forget the network) a little higher (they are highlighted in blue).

After deleting information about the wireless network, simply reconnect, indicating the key to your network.

There is a Wi-Fi connection, but the Internet does not work

This is a completely different story :)

Therefore, we have separate, large articles on this problem, when a laptop connects to Wi-Fi, but the Internet does not work:

I won’t write here why the “No Internet access” and “Restricted” errors appear. The article was already very large. If, after connecting to a wireless network, you encounter a problem when there is a connection, but the Internet does not work, then feel free to follow the links above. I am sure you will find a solution to these problems there.

I wanted to collect all the possible, or at least the most popular, problems encountered when connecting a computer to Wi-Fi. I think I succeeded. If you still cannot solve your problem, then carefully read the article again. If it still doesn’t work out, then describe your case in the comments, and we’ll think about it together.

Why doesn't my phone connect to Wi-Fi, although it recognizes the network? There are several types of this error:

There is an endless and unsuccessful attempt to obtain the router’s IP address;
The smartphone cannot connect to the network, but the access point remains;
The phone does not find the network at all wifi;
The connection occurred, but there is no connection to the Internet.

Let's look at all the ways to solve problems with the router. All types of errors can be resolved using the instructions below. Follow all instructions in order to resolve the error as quickly as possible.

Performance check and problem analysis

In more than 60% of cases, the user cannot connect to wifi due to short-term network failures. Before you learn how to connect your device to your router to troubleshoot a problem, complete all of the following steps:

Reboot smartphone governed by OS Android and your router. The wifi itself must be kept unplugged from the socket for several minutes;
After rebooting your Android device, go to wifi settings and delete the previously saved access point;

Now search again (the phone should be as close to the router as possible during the search).

If you are unable to establish a connection using this method, proceed to the next instructions.

It is also necessary to check the password, since most users may simply enter it incorrectly. Because of this, the connection does not occur and it says “Saved”. To check the entered password, go to Wi-Fi settings. Then go to option view mode desired point access. In the password (or keyword) field, click on the “Show password” checkbox and make sure that it matches the one keyword, which is specified in the router settings.

How to view the password in the router settings? To do this, enter the configuration settings window and go to the “Wireless Security” tab. The password is the value in the PSK Password field. You can also change this value. After changing the password, save the settings and try logging in from your phone again.

Changing the access point name

If all your devices, except those running Android OS, connect to the router, you need to rename the access point. Some Android smartphones and tablets have one common bug - they are unable to recognize a network if its name is in Cyrillic or if the network name contains special characters.

Follow the instructions to change the name:

Go to the router settings;
Go to the main tab and in the SSD Name field, change the name of the access point. Remember, it should not contain additional symbols and letters in Cyrillic. Use only Latin alphabet and numbers;
Save the settings and try to detect the network again.

Changing the Beacon interval option value

Almost everything modern models routers have a number of advanced connection features. You can fix the network connection problem by changing the Beacon interval parameter. Why is this interval needed? Its main purpose is to set the period of time after which telephone will try to receive a special packet from the router that contains information about the operation of the network.

As a rule, on all routers this value is equal to one second (or 100 ms). You can change this parameter yourself to 45 or 70. For most Android smartphones, this value is suitable.

Follow the instructions:

Go to your router's settings;
Go to the "Advanced Settings" tab wireless connection" Another name is "Advanced Wireless";
In the Bacon Period field, enter required value and save the settings;
Reboot your router;
Try connecting to the Internet.

Selecting a connection mode

The cause of the problem may be incompatibility of the communication standard of your smartphone and router. To do this, you need to change the connection mode in the router settings.

Follow the instructions:

Go to your router's settings and enable the advanced wireless network settings tab;
Find the Mode field and change its value one by one. After each change in the standard, save the settings and try connecting to the Internet from your smartphone.

Channel changes in router settings

If your Internet connection is lost suddenly (you haven't done any access point add-ons before), it's possible that the previously used channel is no longer suitable for your network and needs to be replaced.

To do this, follow the instructions below:

Notice! This method This solution is only suitable if absolutely all devices are connected to the router, but there is no Internet connection.

Go to your router settings via your computer using any browser;
Find the tab with wireless network settings;
Then in the “Channel” tab, change the value from “Auto” to any other. Save the settings and reboot the router. Now connect to the Internet again. If necessary, try connecting to a different channel.

Using third-party utilities to reorganize the connection

Using some utilities, you can find out how to connect your phone to the router without errors. Also similar applications help resolve the error by scanning the entire system of the smartphone or tablet. Let's look at a few useful programs:

WiFi Fixer – free utility to diagnose and quickly resolve problems related to connecting to your router. You can download and install the program on your device from official page in the Google store https://play.google.com/store/apps/details?id=org.wahtod.wififixer.

Immediately after launch, the utility resets all settings for connecting to the wifi network and sets the options most suitable for your device. All work occurs automatically, so the user does not need to understand the functionality. The utility can also be launched to work in background, so she can constantly monitor the connection to the router.

Advice! To ensure an uninterrupted network connection, first log into wifi app Fixer and from there connect to the found access point.

FXR WiFi fix and rescue- The following program for setting up a correct connection. She is the most popular application in the Google store in the connection diagnostic utilities section. The program is compatible with all versions of Android OS. If you don't know why the connection isn't working and don't want to troubleshoot the problem yourself, use this application. You can download it from the following link https://play.google.com/store/apps/details?id=com.brilliapps.wifiandmorefixer&hl=ru

To begin the diagnostic and reorganization process, click on the “Fix My Wi-Fi” button. Then select the required access point, enter correct password and wait until the automatic fix procedure completes.

Thematic video:

Wireless technologies will no longer surprise anyone. They entered so deeply into everyday life modern people that it is already difficult to imagine life without them. But the usual is not always simple: from time to time everyone faces such a problem when the laptop does not connect to WiFi, but sees the network. This can happen by various reasons: We will look at the most common problems and their solutions.

Common reasons

It is worth understanding that the problem when the computer sees but does not connect to Wi-Fi can be on the side of the PC or the router. Therefore, you should always check your network first. To do this, simply try connecting other devices to the router, such as a smartphone or tablet. If other gadgets connect to the router without problems, then most likely the problem is on the PC side.

Don't forget about technical specifications. For example, we know that Wi-Fi standards They are different and are designated by a letter. There are quite a lot of them, but three main ones are used in everyday life:

802.11b – opened in 1999. The frequency used for broadcasting the signal is 2.4 GHz. Maximum speed data transfer 11 MBytes.
802.11g – opened in 2003 and operates at a frequency of 2.4 GHz. However, the speed has been increased to 54 MB.
802.11n is the most modern and fastest standard that operates at 5 GHz. The maximum connection speed can reach 300 MBytes

As you can see, the standards work on different frequencies. Theoretically, 802.11n can operate at a frequency of 2.4 GHz, but various problems often arise. Therefore, ideally, the standards on the distributing and receiving devices should match. Nowadays, the vast majority of routers work with all three modes at once, but not all router models support this. Therefore, it is worth checking the technical specifications.

Sometimes connection problems can be caused by data encryption. That is, if you set a password for your wireless network, then the router encrypts the data according to a certain scheme. Sometimes it happens that the computer simply does not support the type of data encryption that is installed in the router and cannot decode the signal. Therefore, it is worth trying to remove the password for the wireless network in the router settings and check whether the PC will connect to open network. To do this, log in, go to the section “ Wi-Fi Security" and here disable the protection.

If the PC connects to an open network, then the problem is the data encryption or the password itself. Therefore, to protect your network, go back to the router settings and set the encryption type to WPA-PSKWPA2-PSKmixed - almost all devices support this mode.

These were the main parameters. Now let's look at what reasons can cause the problem when a laptop sees a Wi-Fi network, but cannot connect.

Problems on the computer side

If it so happens that an error appears when you try, then first of all you need to diagnose the problems. This will allow you to understand what the problem is and in which direction to dig.

How to connect Wi-Fi on a laptop using troubleshooting:

We find wifi icon in the notification area (the so-called system tray in the lower right corner of the desktop).
Right-click on the icon and select “Diagnostics problems”.
Next, carefully read the information on the screen and follow all recommendations. As a result, the system will try to fix the problem. But even if the problem cannot be resolved, at the end of the diagnosis a report will appear indicating the problem.

If diagnosing the problems did not help, then move on to the second method. Here it is worth paying attention to the signal level. If the signal is weak (1-2 sticks), then the PC may not connect to the network. This happens due to too much loss of data packets (the response timeout is exceeded and the connection is disconnected). Therefore in case weak signal move the laptop closer to the access point.

Also, the computer may have various network malfunctions, as a result of which it sees the network, but does not connect to Wi-Fi. This may happen due to large quantity accumulated cache or as a result of some settings, installation of programs that have access to changing adapter settings, and so on. All this can be solved by one in a universal way – resetting network parameters. After the reset, you need to restart your computer.

Problems on the router side

As a rule, if the router does not connect, you need to check the settings. We have already discussed Wi-Fi standards and the type of data encryption above - check these first. It is recommended to install Wi-Fi mode 802.11 bgn mixed. The same goes for the encryption type. If everything is fine with these settings, but the router still does not allow devices to connect, then you should reboot it. Unplug it from the outlet for at least 5-7 minutes, and then plug it back in.

If this does not help, you should reset the router to factory settings. This can be done by pressing and holding special button“Reset” or through the parameters: “System tools”> “Factory settings”.

Before you begin 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 to just connect the provider’s cable to the router, you also need to configure it (set up the Internet and Wi-Fi network ). All of the methods described below are valid if Wi-Fi and the Internet were working for you before, and then suddenly stopped or you cannot connect a new device to Wi-Fi. For convenience, I divided the article into two parts, the first is devoted to 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.

Cannot connect to Wi-Fi network.

Reboot the router.

The first thing you need 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 connect it again after a few seconds. After 1-2 minutes. The device will boot, then try connecting to the wireless network again. To avoid such situations in the future, I recommend updating the router firmware (perhaps the manufacturer knows about the problem and fixed it in the new firmware).

Enabling the Wi-Fi module on the laptop.

Check if Wi-Fi is turned on on the laptop, I won’t turn around, all the ways turn on Wi-Fi I described 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, please note that it may not support modern mode Wi-Fi work -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 Wi-Fi operating modes are described. In order to switch the wireless network mode, you need to go to the router’s web interface, go to the Wi-Fi settings and select the appropriate mode.

Removing a duplicate network SSID.

One of possible problems Inability to connect to Wi-Fi is a duplication of the Wi-Fi network (SSID). Suppose you come to your friends, their Wi-Fi network is called “Home”, you successfully connected to it. Time passed and you came across the same network name with other friends or at home. The laptop (this also applies to tablets and smartphones) tries to connect to the network using the previously saved password, but it fails because this name is used New Password. To solve this problem, you need to remove 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 this, you will see a list of saved wireless networks. If you see that the network you are trying to connect to is in this list, you need to remove it from this list. Select the network and click the "Delete" button. After this, you will need to enter a password to connect to the wireless network.

No Internet via Wi-Fi.

Internet payment check.

The simplest thing that can happen when the Internet is not working is that it’s time to pay for it or the provider is working on it. To clarify the situation, call your provider and find out if you have a debt for the Internet and whether work is being done on the line.

Static IP address.

One of the problems with the Internet not working may be that the registered static address does not have the network settings that are necessary. In this case I recommend using automatic retrieval 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 hotkeys + , enter the command ncpa.cpl and press Enter.

It doesn’t matter which method you used, the result will be the same - a window will appear on the monitor Network connections. Next you need to wireless connection press with two mouse clicks, In the status window that opens, select "Properties" in the properties window "Internet Protocol version 4 (TCP/IPv4)"

Problem with the router.

The Internet may not work due to a router failure; the simplest thing you can do is reboot it. There are situations when the router resets the Internet settings, in this 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 do 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.

Internet and latest electronic technology are very closely woven into our lives. And sometimes problems with Internet access can ruin all our plans and interfere with our work or leisure. The phone not only helps you stay in touch, but also opens the door from anywhere to the World Wide Web, to the Internet. At the same time, no one is immune from sudden problems, then the question arises: why does the phone not connect to WiFi router? This information also applies to those users who do not know why the tablet does not connect to WiFi.

Let's look at the typical reasons below. It must be said right away that the solution may lie in simple manipulations with phone. Therefore, apply all the methods described below, without thinking that this will not help in your situation.

What could be the reasons for WiFi not working on a phone or tablet?

First you need to restart your phone and turn it off/on Wi-Fi network on the phone. Then reboot your router(s). If there is still no network, then the problem is different. Another thing that might help is to remove the battery and connect it again, then restart the phone.

The causes of this problem may be the presence of incorrect network or router security settings, as well as the channel operating mode. What errors can we most often see on our device?

In the connection status we see: “Obtaining an IP address...”, or simply “Connecting...”. But the phone does not connect to the network. That is, you specify the network where you want to connect, but the phone cannot do this.
Authentication problem (authentication error), or simply the status "Authentication...". Usually in in this case The message “Disconnected” appears, and the phone is still not connected to Wi-Fi.
The message in the device is “Saved, WPA\WPA2 protected.”
The phone connects to the router via Wi-Fi, but the Internet does not work and sites do not open in the browser.

What solutions could there be to get your phone or tablet to connect to WiFi?

So, possible options solutions to your problem.

Removing WiFi connection

The first thing I could advise you is to delete the connection that is saved on your phone. To do this, select the network through which you accessed the Internet and click on “Delete” or “Delete this network.” Below in the screenshot you can see what it looks like:

After that, try connecting to this network again.

Reboot the router

Sometimes, if there is a problem connecting not only your phone, but also other devices, you just need to reboot the router. A small note: you don’t just need to unplug and plug in the socket after a second, but unplug the router’s power cable for 10 seconds and only then plug it in again.

You must wait for some time so that there is no power left in the router. Such a circuit is often needed with other devices that are powered by energy. By the way, you can use the button that is on the router itself using the same procedure described above.

Changing the channel in the router

If you haven’t changed any settings and the connection with your router has always been without problems, then you should try changing the Wireless channel. This happens very rarely, but there is a small percentage that this setting can help you.

Where can you change the channel for your Wi-Fi? To do this, you need to go to your router’s settings in the “Wireless” tab and change the channel (Channel), then save the settings, reboot the router and try to connect. If it doesn’t work the first time, repeat the same scheme with other channels.

Check the password you enter when connecting to WiFi

If your phone displays an “Authentication” error, then the problem may be wrong password or in wrong given settings security.

The first thing you need to do is check the correctness specified password. How to do this, since some users may not be prompted to enter a password? You need to delete your connection and re-enter your password by clicking on your network. Always be careful when entering your password. If you have forgotten your password, you can look it up in the router settings.

Here are articles that will help you with this procedure:

If it's not a password issue, then you need to check your security settings. To do this, set the security type to WPA2. The password must be more than 8 characters and you can try use only numbers.

Saved, WPA\WPA2 protection and changing the password in the router

One of the most common problems is when the phone displays the message “Saved, WPA\WPA2 protected” and at the same time the connection icon may show the presence of a connection, but there is still no Internet in the device.

If the options described above do not help, then you need to check the Wireless mode/speed in the router settings ( wireless network), since the phone may not always support the router's operating mode. To do this, you need to set the network to automatic or mixed mode instead of b, g or n.

If you couldn't fix the problem and you are still faced with the dilemma of why your phone won't connect to WiFi, try changing the encryption/security type that I already mentioned:

WPA/WPA2
WPA-PSK

These are the settings on my router:

Enter a new password (key) of 8 characters or more. It is advisable to change the password, as you may have forgotten the password and are entering a non-existent one.

Next - the same scheme: save the settings, reboot the router, delete the connection on the phone and connect, entering a new password when prompted. It should be remembered that the new password will need to be specified in other devices that use this router. For example, if you have a laptop or computer at home, you need to reconnect to WiFi by entering the new password that you specified in the router.

Channel width

Change the Channel Width in the router settings. Usually there are several options: Auto, 20MHz and 40MHz. After the change, save and reboot the router.

If there are other options, try using them.

MAC and IP address filter

Make sure the MAC or IP address filter is disabled. If you have activated this function in your router and have not specified which MAC and IP addresses can connect to the routers, then the problem may be in this particular router setting.

Here are the most common reasons why a tablet or phone does not connect to WiFi. I hope one of my tips helps you.

By the way, if you have a problem with WiFi itself, then read the article “”:

Here is an example when a user could not connect to WiFi from an iPad:
