I can not connect to my WiFi. Typical problems and their solution

"I can not connect to my WiFi" - topics with a similar name appear on various computer forums almost every day. And this is not accidental, because problems with a wireless connection occur quite often. What could be the problem and how to solve it in this or that situation?

Check your internet connection

Before you take any action, make sure that the cable is transferring the Internet. To do this, connect the computer to the modem or router directly, using a wire. There is always a possibility that the problem comes from the provider (for example, when carrying out technical work, they usually disable access to the network for users for several hours).

Check if all devices are connected

Before asking the experts "what to do if I can not connect to my WiFi", make sure that the network equipment is in the active state. Firstly, the Wi-Fi indicator should be on the router itself. If the network is not enabled, enter the IP number (192.168.1.1 or 192.168.0.1) in the browser address bar and connect it. Also, make sure that the appropriate adapter is included on the computer or laptop. You can do this through the "Network Management Center and Society. Access "Windows (go to the tab responsible for the adapter settings and find one that supports wireless connections). On some notebook models, Wi-Fi is turned on by pressing a certain button. You can try to restart the computer and try to turn on the adapter again. If this does not work, you will most likely need to update the driver. In the event that even reinstalling the driver did not give anything, it may be necessary to reinstall the operating system.

If the computer "sees" Wi-Fi, but gives an error when trying to connect

"I did everything described above, but still I can not connect to my WiFi." If the computer displays information about the available networks, but when you try to connect, an error message appears on the screen, the problem may be due to the incorrect mode of the router's operation. Go to its settings (how to do this, you already know from the previous paragraph) and change the mode from standard to mixed (Mixed), B / G / N or B / G.

Network without Internet access

This, perhaps, is one of the most common problems, why does not WiFi connect. Windows 8, incidentally, is subject to this much more than previous versions of the OS. This is due to the fact that the computer receives an incorrect IP address or DNS server address. First you need to find out what is wrong. To do this, open the list of available networks, click the right mouse button on the one to which we want to connect, and select the "Status" item. If you did not receive or received an incorrect IP-address, the line "IPv4-connection" will be displayed with the message that there is no access to the network. You can verify this by opening the "Changing adapter settings" in the Network Management Center. After finding your wireless connection, right click on it and open the properties, and then look at the IPv4 protocol. If there are addresses in the settings, write them to a separate sheet (they may still be needed), and then change the options so that the IP address and the DNS server address are automatically generated. Confirm the changes made and check the access to the Internet. If this does not work, restore the addresses used by the default router.

Problems associated with incorrect DNS server addresses also lead to the fact that the Internet is not connected via WiFi. As in the previous case, they are displayed in the status window of the wireless network. In this case, near the line "IPv4-connection" you will see the inscription "Without access to the Internet". This is corrected, again, in the protocol settings. Try to set automatic reception of necessary addresses or to write in the column of the preferred DNS-server "8.8.8.8", and in the column of the alternative - "77.88.8.8" (public addresses of the DNS servers of Yandex and Google).

We hope this article has helped you, and the need to write to specialists with the question "why I can not connect to my WiFi" is no longer for you!
