The laptop does not connect to the wi-fi network. Wi-Fi is connected, but the Internet does not work


Wireless technologies will no longer surprise anyone. They have entered so deeply into the life of modern people that it is difficult to imagine life without them. But the usual does not always turn out to be simple: from time to time everyone faces such a problem when the laptop does not connect to WiFi, but sees the network, and there is no access to the Internet. This can happen for 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 the technical specifications. For example, we know that Wi-Fi standards are different and are designated by a letter. There are quite a lot of them, but three main ones are used in everyday life:

  1. 802.11b – opened in 1999. The frequency used for broadcasting the signal is 2.4 GHz. The maximum data transfer speed is 11 MBytes.
  2. 802.11g – opened in 2003 and operates at a frequency of 2.4 GHz. However, the speed has been increased to 54 MB.
  3. 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 operate at 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 an open network. To do this, go to the router settings, go to the “Wi-Fi Security” section and disable the protection here.

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 when you try to connect to Wi-Fi an error appears, 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:

  1. Find the Wi-Fi icon in the notification area (the so-called system tray in the lower right corner of the desktop).
  2. Right-click on the icon and select “Diagnostics problems”.
  3. 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, if the signal is weak, 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 a large amount of accumulated cache or as a result of some settings, installation of programs that have access to changing adapter parameters, and so on. All this can be solved in one 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 set the Wi-Fi mode to 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 the special “Reset” button or through the options: “System Tools”> “Factory Resets”.

Again I want to try to answer Daniel.

Daniel, I have installed the “N Series Multifunctional Wireless Router” TP-LINK TL-WR842N.
I purchased and installed it when I was tired of “fiddling” with wires that were constantly getting in the way under my feet and not only for that reason.
Long before buying a router, I bought three “Wireless USB Network Adapters” TL-WN823N for my three desktop computers
and distributed WI-FI Internet from his “main” (most powerful) computer, to which a high-speed Internet cable was connected. All traffic went through my computer, which entailed inconvenience - when I turned off my computer, I cut off Internet access to other family members and the load on my processor was noticeable.
By purchasing a router, I received a device that provides all my devices (personal devices, laptop, tablet and two smartphones) with equal and balanced speed access to the Internet.
Following the instructions in the router's Quick Setup Guide, I created my own wireless network, with my own password (not to be confused with the password for accessing a high-speed wired connection).
It is important here that the router connects to the Internet automatically, which is indicated by green lights. If the large light bulb (LED) glows green, it means the router has connected to the Internet and is ready to distribute the Internet; if it lights up yellow, then something is wrong with the connection to the Internet provider via cable (perhaps it is not configured correctly).
Connecting to the Wi-Fi network we created is the same for both a laptop and a phone - look at the list of available wireless connections, select the network with the name that we entered when setting up the router, and click “connect.” When you connect for the first time, the system will require you to enter a password - enter the password, again, the password that we “hammered” into the router during setup (but this is not the password for the high-speed connection, you can forget that password, the router will always remember it).

Now about what all the fuss is about. As I understand, you decided to connect your computer to the router using a wire, and other devices using Wi-Fi. I didn’t try it, but immediately hung the router in the far corner and haven’t touched it since. I don’t remember why I didn’t try the way you are trying to connect, or maybe I even tried, but I can assume that it won’t work just like that, “from a running start.” Recently I read articles on the Internet, looking for an answer to the question of how to expand the Wi-Fi coverage area. So - it's not that simple. It is necessary to organize several networks and hierarchical dependence of devices (the required number of routers).
From the description of the TP-LINK router it does not at all follow that those four yellow connectors are an analogue of a HUB, designed to connect several computers to the Internet as if they were part of a Wi-Fi network, and they are not repeaters or branchers of the wired Internet. It's still called a wireless router.....
I managed to find a description of the router on the Internet in Russian and with pictures:
img.mvideo.ru/ins/50041572.pdf
Perhaps you will be able to learn something and I would be grateful if you later share the solution you found (if you find it).
But I wouldn’t suffer for a long time and would buy a USB Wi-Fi adapter….

Nowadays, wireless networks are very widespread. This is because a cable connection is not required to connect to the access point. This, in turn, allows users to move freely to the coverage area. But what to do if the laptop does not connect to WiFi? This is exactly what this article will discuss.

The fact is that the question of why I can’t connect to a WiFi network from a laptop comes up quite often due to a variety of problems with the equipment, and not every user is able to solve them on their own. There can be many reasons for a failed connection. We will analyze the most common mistakes and their solutions.

Why doesn't my laptop connect to the wireless network?

Before moving on to the main topic of the article, you should look at... What is needed to create them and how to connect to them. Everything is simple here. To organize a group, you need an access point to which subscribers will connect. This means that the main settings are made precisely in the parameters of such access points. Thus, if the laptop does not connect to the Internet, then, first of all, you should check the router settings.

It is worth noting that in the vast majority of cases, wireless routers are used as an access point. And, as a rule, connection problems are related precisely to the settings of such a device.

How a WiFi router works: Video

But there is nothing complicated here. Absolutely everyone can cope with this. So, here we come to the reasons why connection problems may arise:

  1. First of all, you need to check your router settings.
  2. Driver problems.
  3. Problems with WiFi adapter.
  4. Software glitches.

Checking router settings

So, let's get straight to the point. First, you need to make sure that the router is turned on and working. If your laptop does not connect to Wi-Fi, then it is quite possible that the wireless connection is disabled on the router. It's very easy to turn it on. We will look at how to do this using the D-LinkDir-615 Wi-Fi router as an example. To do this, connect to it using the cable that comes with the kit.

Next, open your favorite browser and enter the router’s IP in the address bar. You can find it in the instructions for the device, as well as on the device itself (carefully inspect it from all sides). If you still can’t find the information you need, then open the command line.

There are several ways to open the command line. If you are using Windows 8, the easiest way is to press the Windows + X key combination and select “Command Prompt (Admin)” from the menu that appears. If Windows 7, then simultaneously press Windows + R, in the window that appears, write CMD and click “OK”. In the window that opens, enter the ipconfig command. Find the "Default Gateway" line. The values ​​of this parameter are the IP address we need. Typically this is 192.168.0.1 or 192.168.1.1. But, this data may differ depending on the router model.

How to easily find out the IP address of your WiFi router: Video

So, enter the desired address in the browser and press “Enter”. Next, you will be asked to enter your username and password. We write – admin, admin respectively. Here we are in the router settings menu. Now at the bottom of the screen you need to click “Advanced settings”. Several additional windows will appear. We are interested in the window called “WiFi”. Here we are looking for the “Basic Settings” subsection. We go into it and the very first thing is the “Enable wireless connection” item. Here you just need to check the box.

It is worth noting that in addition to this there may be other problems:

  • Your computer's MAC address has been filtered.
  • The password was entered incorrectly (if the network requires you to enter a key).
  • Device freezing.

Checking the wireless network status

So, if the wireless connection is turned on, but the laptop still does not want to connect to the WiFi network, then you should check that the password is entered correctly. If you are, then we connect to the router using a cable and perform all the above steps to enter the settings menu and open advanced options.

Now we are interested in “Security Settings” in the “WiFi” section. Here the first line is the network authentication (encryption type). A little lower in the “PSK encryption key” line you will see the passphrase that is used to connect. Here you can change it.

What to do if you forgot your WiFi password: Video

MAC Address Check

Why does the Wi-Fi network on my laptop not connect when the password is entered correctly? In this case, it is worth checking the router filters. The fact is that to increase security, special services are used that filter devices, allowing or denying connections to specific subscribers. First of all, we check the MAC filter.

It is located in the "WiFi" section. We go into it and look at the “Restriction mode” item. Typically it should be disabled. But in some cases it is included. If we are talking about a home network, then it is better to disable it. If it is still necessary, then go to the second tab “MAC addresses” and check if your address is in the list.

It is worth noting that if the MAC filter mode is set to “Allow”, then your address must be in the list. If the “Deny” mode is used, then your device should not be on the list. Otherwise, you simply will not be able to connect your laptop to wi-fi.

The answer to the question why the WiFi network on a laptop does not connect is as follows.

Budget Wi-Fi routers such as Asus, D-Link, TP-Link, Zyxel, Linksys and so on tend to freeze. This may occur due to heavy load when connecting a large number of people. There may also be freezes after unplugging the device from the outlet (for example, if the electricity in the house is turned off).

There may be other reasons. In any case, everything can be resolved by simply rebooting the device. In the case of the D-Link router, everything is extremely simple. Connect to the device using a cable and enter the settings menu.

At the very top you will see the line “System”. Hover your cursor over it and select “Restart” from the drop-down menu.

In your TP-Link Wi-Fi router, you need to go to the “System tools” section and select the “Reboot” sub-item. Also, in special cases, you can simply unplug the device from the outlet for at least 7-10 minutes.

Checking the wireless adapter

The router is configured correctly, but the laptop still does not receive Wi-Fi, what should I do? This means that the problem is hidden in the operating system or in the adapter itself. First of all, you should check whether it is turned on. But, if you turn it off (or it doesn’t turn on), the computer will not see available connections at all. It is turned on by pressing the key combination Fn + Wi-Fi enable button (has a corresponding icon).

So, the adapter is turned on, but the laptop still does not connect to the WiFi network. In this case, you should check the drivers. It is worth noting that if they are not installed, the Wi-Fi adapter will not work at all or even turn on. But sometimes, even installed software may not work properly. You can check this in Device Manager.

There are several ways to open the desired service. The simplest one is to press the Windows + R key combination and in the window that appears, write the command mmc devmgmt.msc. You can also find the My Computer shortcut on your desktop, Start menu, or file manager (Windows Explorer). Right-click on the shortcut and select “Properties”. In the window that appears, select "Device Manager".

Here we are interested in the “Network adapters” section. Let's open a thread. The list that appears shows all network devices:

  • Bluetooth module (if available).
  • Wi-Fi adapter.
  • Network card and others.

We are interested in the second. As a rule, in addition to the name and model of the module itself, it is designated with the words “Wireless Network Adapter”. If this adapter is highlighted with an exclamation point in a yellow triangle, then this indicates that the software or the device itself is not working correctly.

If you double-click on the adapter, a window will open in which you can find out the error code. This will allow you to fix it faster. You can also simply delete it by right-clicking and selecting the appropriate item. After that, restart your computer and reinstall the driver again.

The necessary software is contained on the disk that came with the laptop. They can also be downloaded from the official website of the laptop manufacturer.

How to reinstall WiFi driver in Windows 8: Video

So, the laptop does not connect to the Internet even after reinstalling the driver, what should I do?

At this point, we should check the status of the wireless connection. To do this, right-click on the network icon in the tray (the area of ​​the screen in the lower right corner). Select Network Sharing Center. In the window that opens, enter the “Change adapter settings” menu. Find the wireless network shortcut and right-click on it. Select “Properties”.

In the window that appears, select Internet Protocol version 4 (TCPIPv4) and click “Properties”. Here the markers should be set to the “Obtain an IP address automatically” and “Obtain DNS server address automatically” items. After that, click “Ok” and try to connect.

Why doesn't my laptop connect to the Wi-Fi network? We checked all the settings, but there is still no connection. This suggests that diagnostics should be performed. To do this, right-click on the network icon in the tray and select “Diagnostics problems”. The system will automatically start searching for errors; all you have to do is follow the prompts on the screen.

    Hello. Please help me solve the problem. I bought a laptop (lenovo g50-45). Reinstalled the system. Now I can’t understand why the Wi-Fi doesn’t work. The driver is installed, the access points are displayed, but I can’t connect to them. I tried everything I could and knew, nothing helped. All drivers are installed except (PCI encryption / decryption controller), this may be the reason.

    Bezprovodoff team 12/18/2015 12:40

    Hello. First, please clarify what operating system is installed? What was it originally on this laptop? What drivers did you install (where did you get them)? Maybe the drivers just don't work with your operating system. Here the reason could be anything. Every little thing can be important. When you try to connect, when a failure occurs, there is a “Troubleshooting” or “Troubleshooting” button in the window. Have you tried this procedure? To reset all WiFi settings, you need to launch a command prompt with administrator rights and run the following commands in it:

    route –f.
    netsh interface reset all.



    netsh winsock reset.
    netsh firewall reset.
    After each command, press “Enter”. After this, you need to restart your computer. But, I recommend that you first launch the hardware manager, go to the “Network adapters” folder and remove all network adapters from it, including Wi-Fi. And only after that launch the command line and execute the above commands. First download the necessary drivers from the official website of your laptop manufacturer (the drivers must match your OS and its bit depth).

    Bezprovodoff team 12/18/2015 12:41

    Hello. First, go to the Network and Sharing Center. Go to the “Wireless Network Management” section. Here, delete the network you are trying to connect to (if there is one). Now, you need to download the necessary drivers (for WiFi for your laptop and your operating system). Drivers should be downloaded from the official website of the laptop manufacturer. After that, open the hardware manager and go to the “Network adapters” folder. Here we remove all network adapters (we have already downloaded the drivers for them). Now launch the command line with administrator rights and execute the following commands in it:
    netsh int ip reset (if you can’t register it or an error pops up, then write “netsh int ip reset c:\resetlog.txt”).
    route –f.
    netsh interface reset all.
    netsh interface ip reset resetlog.txt.
    netsh interface ipv4 reset resetlog.txt.
    netsh interface ipv6 reset resetlog.txt.
    netsh winsock reset.
    netsh firewall reset.
    After each command, press “Enter”. Reboot the computer. Now we install new drivers, which we have already downloaded previously. That's all.

    Good afternoon
    I have a laptop ACER Aspire V3-571G.
    I’ve set up Wi-Fi and am connecting from various devices, but I can’t access the Internet... what could it be? I downloaded the drivers from the official website, but did not change the firmware. In the laptop, everything is configured according to the settings suggested above. What could be the reason?

    Bezprovodoff team 01/13/2016 20:47

    Hello. If you use a router, then the router itself must be connected to the Internet. That is, the provider’s cable is connected to the router. Next, go to the router settings and configure WAN. There can be a lot of different configuration options here. For example, many use PPPoE technology for access. In this case, you need to enter your login and password in the WAN settings. But, this may require manual network settings (IP address given to you by your provider, subnet mask, default gateway, and so on). Only your provider and you know all this data. Sometimes, when connecting via PPPoE, you need to select Dynamic IP. That is, if your provider provides network parameters automatically, then you only need to enter your login and password. In addition, there is a version with MAC address binding. In this case, you need to call your provider and ask him to register your router and link it to the MAC address. Again, the network settings can be automatic or manual, and Internet access can be via PPPoE or other versions of the protocols. Here you need to call your provider and clarify how exactly the router is configured in your specific network. This concerns the router settings (the question is individual and you need to take into account a lot of factors). Now regarding the hardware. It happens that the router itself is buggy. But, this only applies to older versions of routers that have been in operation for a long time. If your router is new, then it is unlikely that there are any problems with it. In any case, you must first check the WAN and network settings, and also contact your provider. And if you have already tried all the options and still cannot access the Internet, then draw the conclusion that the router is faulty.

    Dear experts - help!!!
    I've been fighting for 2 days now.
    A parcel arrived from China —-Alfa Awus036NH
    Realtek RTL 8187
    The firewood was installed automatically.
    1. On an HP laptop, via Alfa Awus036NH I can’t connect to my router, it doesn’t connect to the Internet.
    2. In the WiFi network scanning program, I see both my WiFi devices and the built-in adapter and Alfa.
    I switch to Alfa Awus036NH - scanning stops.
    3. In AirSlax, both adapters are detected and work in monitor mode.

    When I click on “connect to network”, the laptop does not go there. When I go to the “Network and Sharing Center” it does not give me any information about viewing basic information about the network and setting up connections. When I click on “Change adapter settings” nothing appears there. Everything is fine with wi-fi, other devices are connected to wi-fi. Windows 7.

    Hello. Firstly, drivers must be installed. The fact that the system automatically determined it does not mean anything. The system “understood” what device it was dealing with, but without drivers the device will not work correctly. The second point is that if there are two WiFi adapters in the computer, then a conflict may arise between them. Again, you need to install drivers for both adapters. Also check what errors the system gives when you try to connect to the router. What errors appear when you try to access the Internet. Describe everything in detail. The more information, the faster I can help you.

    Bezprovodoff team 03/19/2016 10:34

    Hello. There is a universal method for solving such problems. Try this. To begin, download the drivers for your WiFi adapter and network card (LAN) from the official website of the laptop manufacturer (they must be on your PC, we will return to them later). Now launch the hardware manager and find the “Network adapters” folder. Delete everything that is there from this folder (one by one, without restarting the computer). After that, launch a command prompt with administrator rights and do what is described in this video tutorial (this is necessary to reset the network cache and network parameters) -. After the reset, restart your computer. Now install the drivers previously downloaded from the official website. Reboot your PC again.

    Bezprovodoff team 03/19/2016 10:35

    Hello. First, tell me how the WiFi network is organized? Are you using a router? If yes, which router? Judging by the symptoms described, the problem is not only on the computer. But also on other devices. This means there is a problem with the access point. Accordingly, you need to look for the problem in the router. The first thing you should check is whether the WAN connection is configured correctly. I won’t help you here, because the WAN parameters are set by your provider (parameters unique to each). Therefore, you need to call your provider and find out how to configure the router for your network. The second thing to do is check your WiFi settings. There are several important points here. First, go to the basic WiFi settings. Here you need to check which WiFi mode is being used. Ideally, you need to set 802.11b\g\n mixed. This mode may reduce the speed slightly, but any type of device will be able to connect to this network. Now go to the WiFi security settings. Here we need to set the encryption type to WPA\WPA2 Personal, and in the lines “Version” and “Encryption” set “Automatic” (on D-Link we set WPA-PSK\WPA2-PSK mixed). If it doesn’t help, then most likely you will have to reflash the router or even buy a new router.

    Hello. The laptop refuses to connect to wi-fi with a password. That is, I set up the router and successfully connected it to my phone and tablet (everything works fine there). It also works on a laptop, but provided that the password is disabled.
    Please tell me how to fix it?

    Bezprovodoff team 04/01/2016 19:23

    Your task is to do this (exactly as I will describe further and in the same sequence). First, go to the official website of your laptop manufacturer. Find your laptop and download drivers for WiFi and network card (taking into account the version and bit depth of the installed OS). Let the driver installers be on your PC; they will be needed later. Now launch Device Manager, find the “Network Adapters” folder and delete everything you see there from this folder. After that, launch a command prompt with administrator rights and perform the following actions in it: https://www.youtube.com/watch?v=T0vOyaSeY3Y. After this, restart your computer. Now install new drivers. Restart your PC again. This should solve your problem.

    Hello. I can't connect to wif normally. Every time I turn on the laptop and try to connect, it says “Windows was unable to connect to the Kabelteh device.” The only saving grace is that it is possible to quietly reboot the router and wifi on the laptop, only after that I connect. But since there are about 10 people here on the Internet, it’s impudent to reboot the router just because it’s not working for me, it’s disrespectful, I’m turning to you for help. Tell me what to do in this case. I went into the device manager - everything is fine there. I’ve been using this connection for 2 weeks now and I’m always having trouble connecting... If I don’t reboot the router, then after a while (5 minutes - 2 hours) I connect! What should I do to start connecting without problems?

    Hello. What laptop (model)? Maybe your router provides WiFi in 802.11n mode, but your laptop only supports 802.11g or b. In this case, you will not be able to connect to the network. In the router settings in the “WiFi” section, you need to check which standard is installed. If possible, you should select the “802.11b\g\n” mode - this is a mixed mode. In this mode, all WiFi standards will be able to connect to the router. Do other devices (phones, tablets or other computers) connect to your home router? You can try resetting the network settings on your computer - https://www.youtube.com/watch?v=T0vOyaSeY3Y(commands should be executed in a command line running with administrator rights MANDATORY!). Better yet, remove the old drivers, do a reset, restart the PC and install new drivers and restart the PC again.

    Hello, I really need your help. We checked into the hotel, entered the password on the phone - wi-fi was working. But on the Lenovo ideapad Y510P laptop... The password is correct, SOMETIMES it connects to it with one stick and immediately stops. In other cases, it simply does not connect to the network.

    Hello. If the signal is weak (the router is located too far from the laptop), then the laptop will not be able to connect to the network normally. On a laptop, sometimes poor signal reception may be due to the lack of official drivers. That is, when installing Windows 8 or 10, the system itself detects all the components of the computer and no drivers are installed. But the drivers that Windows offers do not always work correctly. In your case, you can try to reinstall the WiFi drivers. First, download drivers for the network adapters that are on your computer (WiFi, LAN network card, and so on). Keep the drivers on your computer; you will need them later. Now, open the device manager and delete everything you find there from the “Network adapters” folder. After that, open a command prompt with administrator rights ( http://owindows8.com/nastrojka/komandnaya-stroka/komandnaya-stroka-kak-rabotat.html) and run the following commands in it - https://www.youtube.com/watch?v=T0vOyaSeY3Y. After this, restart your computer. Now install the drivers that you previously downloaded from the official website (for the installed OS, taking into account its version and bit depth). Reboot your PC again. If the drivers could not be found or there are problems in the search, then here is a program for automatically installing drivers - https://goo.gl/dkxVUs.

    Windows 7 does not connect to the wireless network if a password is set for Wi-Fi. I set up the wireless network security key, enter it in, and it says Windows cannot connect. I remove the password and connect to the network without problems. I can't make a mistake in the password.

    Hello. Please check. Is the network distributed through the router? What type of encryption do you install on your router? Try changing encryption types (encryption method) and try to connect the tablet. That is, set WPA-PSK and connect the tablet. If it connects, try selecting the “WPA-PSK\WPA2-PSK” option. In general, try different options. Also try changing the broadcast channel. Try to install from the first one and check different channels one by one.

    Bezprovodoff team 09/08/2016 13:45

    Hello. The fact is that different systems have different protocols. You need to distribute the network via the command line. That is, configure distribution on the command line. Here is an excellent article that describes three ways to distribute WiFi -. In your case, either setting it up on the command line or using the Virtual Router Plus program will do.

    Hello!
    We recently changed the password for Wi-Fi, after which we needed to re-enter the same password on the laptop (not as if connecting to the network for the first time, but through the “properties” of the network). Everything is fine with the laptop, it works. But the parent netbook also stopped connecting, but changing the password did not solve the problem, the connection does not occur. Every time you go to “properties” the old password is shown. Rebooting the modem and router also did not give any new results.
    I will be glad to receive your help.

    Hello)
    HP laptop, windows 10.
    Everything is fine with Wi-Fi, everything works. I went into the game, which after a while crashed. Deciding to restart it, I exited and clicked the shortcut again to launch it. During startup, a screen suddenly appeared with a sad smiley and a message about a Windows error and that a reboot would occur. After rebooting, the Wi-Fi connection was lost. The Wi-Fi icon disappeared altogether, wherever possible. I went into the device manager, but there was no trace of the Wi-Fi adapter there. Clicked “View – show hidden devices”. Voila, my Wi-Fi adapter appeared in hidden devices. In its properties it says that the device is not connected, code 45.
    So, the Wi-Fi adapter burned out like a match?

    Hello! I have a TOSHIBA laptop, WINDOWS 10. Problem: after putting the laptop to sleep, you can connect to Wi-Fi only after restarting the router (I connect manually, it doesn’t work automatically). Thank you.

    Hello. You need to delete the old network, as a conflict simply arises. If Windows 7 is installed, then open the Network and Sharing Center, in the menu on the left, go to the “Wireless Network Management” section, find your network here and delete it (right-click and select delete). After that, simply connect to your network and the system will ask you to re-enter your password. If Windows 10 is installed, then go to “Settings”\”Network and Internet”\”WiFi”. Here, under the “Wireless network” heading, there will be the inscription “Manage WiFi network settings.” Click on this inscription. Scroll to the very bottom of the page and here you find your old network (for which you need to change the password). Click on it with the left mouse button and select “Forget”. After this, reconnect to your WiFi network in the usual way, and the system will ask you to enter a password. That's all. If it doesn’t help, then reset the network parameters - https://www.youtube.com/watch?v=T0vOyaSeY3Y.

    Hello. Try this. First, remove your WiFi adapter from your computer (if it is hidden, then remove it from there too). After this, launch the command prompt with administrator rights and reset the network settings - https://www.youtube.com/watch?v=T0vOyaSeY3Y. Restart your computer and install drivers for the WiFi adapter. But don’t do an automatic update, but go to the official website of the laptop manufacturer (you can download it from another PC or from a phone or tablet, and then transfer the installation files with a flash drive) and download the drivers for your Wi-Fi adapter. After this, install the driver and restart the PC. It should work. If it doesn’t help, then there are two options - either you picked up a virus that damaged the registry or Host files (In this case, just reinstall the OS) or the adapter burned out. If you have a second laptop, you can try moving the Wi-Fi adapter from it and check if it will work. If so, then buy a new adapter. If it doesn’t work, then reinstall the OS.

    Good day. I have such a problem, I don’t understand what’s wrong, whether it’s in the laptop or in the router, now I’ll describe the essence of the problem. I bought an Acer E5 571G-597D laptop (it says on the sticker) There is a connection to Wi-Fi, BUT the Internet often drops in the flesh until disconnected, but the Wi-Fi icon is on, saying it’s connected, all Energy modes are turned off, everything is set up * (I used your site) I tried it on another Wi-Fi network laptop, so on another network it works without any interference, I looked everywhere for a solution to this problem and I just can’t find it answer, I also did network diagnostics, nothing helps at all, the LAN cable from the router works fine, but Wi-Fi doesn’t work, and in the rest of the house it also works fine with Wi-Fi, I’m the only fool, I really need your help.

    The power mode may need to be adjusted. This article describes how to configure the power supply for a WiFi adapter -.

    Hello. Try doing a reset and reinstalling drivers for your network equipment. that is, download drivers for network cards (WiFi and LAN - network card). Let the installation files be on your PC. They will be needed later. Next, go to Device Manager, find the “Network Adapters” folder and delete from it everything you find there. After this, you reset the network parameters - (the command line must be launched with administrator rights). Restart your PC and install the drivers (which you previously downloaded). Reboot your PC again. After this everything should work correctly. Remember that drivers (especially if you use Windows 8 or 10) must be installed yourself (not updating the equipment automatically), namely, download drivers for your model from the official website of the laptop manufacturer and install them yourself.

    Hello! The laptop does not connect to Wi-Fi the first time; restarting the computer helps solve the problem. This problem occurs every day, for a week now. Please tell me what could be the problem?

    Hello! I have this problem. Recently we reinstalled Windows on a laptop (Lenovo B570e). I used to have Windows 7 and now they installed 7. I stopped connecting to wi-fi at home. I turn on the distribution from my phone, everything connects and works fine for my friends. But at home, not at all. Phones and tablets work on Wi-Fi at home. But he doesn’t want a laptop. Or it doesn’t see the network at all, or it connects for a couple of seconds and immediately resets. I do not know what to do. Help, those who know)) I’m not very good at this myself. If anyone has had such problems, write down in a more understandable language so that common people can understand))

    there are two networks pocha and rt wi-fi, the laptop connects to pocha, but does not connect to rt wi-fi (it says it can’t connect to...), the phone connects to both pocha and rt wi-fi, the laptop stopped connecting after reinstalling windows . on a windows 7 laptop laptop model: Acer Aspire As 5250-E45263232
    the drivers are ok

A fairly common problem among owners of laptops with Windows 10, Windows 7 or 8 (8.1) - at one point in the notification area, instead of the usual wireless Wi-Fi connection icon, a red cross is displayed, and when you hover over it, a message stating that there are no available connections.

Moreover, in most cases, this happens on a completely working laptop - just yesterday, perhaps, you successfully connected to an access point at home, but today this is the situation. The reasons for this behavior may be different, but in general terms, the operating system believes that the Wi-Fi adapter is turned off, and therefore reports that there are no connections available. And now about ways to fix this.

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


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

To launch Windows Device Manager, press the Win+R keys on your laptop keyboard and enter the command devmgmt.msc, and then press Ok or Enter.

In Device Manager, open the “Network Adapters” section, right-click on the Wi-Fi adapter, see if there is an “Enable” item there (if there is, turn it on and do not do everything else that is described here, the message “No connections available” should appear) disappear) and if it is not there, select “Delete”.

After the device is removed from the system, in the device manager menu, select “Action” - “Update hardware configuration”. The wireless adapter will be found again, drivers will be installed on it and, perhaps, everything will work.

See if the WLAN AutoConfig service is enabled in Windows

In order to do this, go to the Windows control panel, select “Administration” - “Services”, find “WLAN Auto Configuration” in the list of services and, if you see “Disabled” in its parameters, double-click on it and in the field Set the “Startup Type” to “Automatic” and click the “Run” button.

Just in case, look through the list and if you find additional services that have Wi-Fi or Wireless in their name, turn them on too. And then, preferably, restart your computer.

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

Today we will look at:

Very often we encounter such a problem as lack of access to Wi-Fi. This problem mainly occurs in Windows operating system. What is the reason, and what will be the solution to the problem? This is what we will now try to find out.

So, there are several reasons why a laptop cannot connect to Wi-Fi. Problems with the settings of the laptop itself, outdated drivers. Let's take a closer look at these reasons and find ways to fix the problem.

No wireless adapter connected

The problem is that there is no connected wireless adapter on the laptop itself. In each laptop model, manufacturers install a button to turn the Wi-Fi adapter on or off on the F keys. Look at your keyboard and look for the Wi-Fi symbol, usually located at F5, F10 or F12.

Next, we find the Fn function button and simultaneously press Fn and F12 several times (you press the key where the Wi-Fi icon is drawn), see what happens, whether there are any changes. Sometimes it happens that Fn is not active because there are no drivers installed; if when you press F12 and Fn the laptop does not react at all, then check the Fn key by turning up or down the volume.

In addition to the adapter, you need to check in the network connection settings whether the network card is connected.


Did not help? So, we do the following:


Drivers not installed

This problem mainly occurs when Windows is suspended on a laptop.
If a non-professional installed the system, he might not have installed it, which led to Wi-Fi being turned off.

To check this, you need to do a few simple manipulations:

Using Win+R, go to the “Run” window, give the command devmgmt.msc, and select the name of your router from the list. If there are no drivers, then instead of the router name the standard “Ethernet controller” will be indicated.

So, in the list, instead of the name of the router, we found “Ethernet controller”. There are two ways to solve the problem:

True, for this you also need to download the driver from the official website, but you do not need to install it. In Device Manager, right-click on the name of the adapter and then select the “Update drivers” command. Then restart the laptop and check if Wi-Fi is connected.

Troubleshoot connection problems

Click on “Properties”, a list appears in the newly opened window, in which we find the item: IP version 4 (TCP/IPv4), double-click on it with LMB, the window with DNS settings and IP address parameters opens again.

Here, be sure to check the box next to “Use the following IP address.” We specify the parameters exactly as in the example, click OK, and check.

Disabled WLAN services

If all of the above methods do not help, the last thing you can do is check the WLAN auto-configuration service. Of course, shutdowns happen extremely rarely, but everything happens at some point, and checking it won’t hurt. So, press the combination Win+R that is already familiar to us, enter the command services.msc and click OK.

In the window that appears, we find: “WLAN AutoConfig Services”, right-click on it, and in the drop-down window, execute the “Run” command.
