“I can’t connect to my WiFi” - topics with a similar name appear on various computer forums almost every day. And this is not at all accidental, because wireless connection problems occur very often. What could be the problem and how to solve it in a particular situation?
Check your internet connection
Before taking any action, make sure that the cable transmits the Internet. To do this, connect the computer to the modem or router directly, using a wire. There is always a chance that the problem comes from the provider (for example, when conducting technical work, they usually disable network access for users for several hours).
Check if all devices are connected
Before asking specialists “what to do if I cannot connect to my WiFi”, make sure that the network equipment is in an active state. Firstly, the Wi-Fi indicator should be on on the router itself. If the network is not turned on, enter the IP number (192.168.1.1 or 192.168.0.1) in the address bar of the browser and connect it. You should also make sure that the appropriate adapter is turned on on the computer or laptop itself. This can be done through the "Network Control Center and commonly. access »Windows (go to the tab responsible for the adapter settings and find the one that supports wireless connections). On some laptop models, Wi-Fi is turned on by pressing a specific button. You can try restarting the computer and try turning on the adapter again. If this does not help, most likely you will need to update the driver. In the event that even reinstalling the driver failed, 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’t 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 incorrect router operation. We turn to its settings (you already know how to do this from the previous paragraph) and change the mode from standard to mixed (Mixed), B / G / N or B / G.
Network without internet access
This is perhaps one of the most common problems why WiFi is not connected. Windows 8, by the way, is subject to this much more than previous versions of the OS. This happens because the computer receives the wrong IP address or DNS server address. First you need to find out what exactly is wrong. To do this, open the list of available networks, right-click on the one you want to connect to, and select the "Status" item. If an incorrect IP address was not received or was received, a message stating that there is no access to the network will be opposite the line “IPv4 Connection”. You can verify this by opening the "Change adapter settings" in the network control center. After finding your wireless connection, right-click on it and open the properties, and then look at the IPv4 protocol. If any addresses are registered in the settings, write them on a separate sheet (they may still be needed), and then change the options so that the IP address and DNS server address are obtained automatically. Confirm your changes and check your internet access. If this does not help, we restore the addresses used by the router by default.
Problems associated with incorrect DNS server addresses also lead to the fact that the Internet does not connect 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 fixed, again, in the protocol settings. Try to automatically obtain the necessary addresses or enter “8.8.8.8” in the column of your preferred DNS server, and “77.88.8.8” in the alternative column (public addresses of Yandex and Google DNS servers).
We hope this article has helped you, and the need to write to specialists with the question “why can not I connect to my WiFi” has disappeared for you!
