"I can not connect to my WiFi" - topics withwith a similar name appear on various computer forums almost every day. And this is not at all accidental, because problems with a wireless connection occur very often. What could be the problem and how to solve it in a given situation?
Check your internet connection
Before taking any action,make sure 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 carrying out technical work, they usually disable the network access for users for several hours).
Check if all devices are connected.
Before asking specialists "whatif I can’t connect to my wifi ”, make sure that the network equipment is active. Firstly, the Wi-Fi indicator should be 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 Society. accessing Windows (go to the tab that is 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 certain button. You can try to restart the computer and try again to turn on the adapter. If this does not work, you will most likely need to update the driver. If even reinstalling the driver did not give anything, you may need 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 notI can 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 related to the wrong mode of operation of the router. Go to its settings (how to do it, 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 is perhaps one of the most commonproblems why wifi does not connect. Windows 8, by the way, is subject to this much more than previous versions of the OS. This happens because the computer gets the wrong IP address or DNS server addresses. First you need to figure out what exactly is wrong. To do this, open the list of available networks, right-click on the one to which we want to connect, and select the item "Status". If an incorrect IP address was not received or received, next to the line “IPv4 connection” there will be a message that there is no access to the network. You can check this by opening the “Change adapter settings” in the Network Control Center. Having found your wireless connection, right-click on it and open properties, and then look at the IPv4 protocol. If any addresses are registered in the settings, write them out on a separate list (they may still be needed), and then change the options so that the IP address and the DNS server addresses are obtained automatically. Confirm the changes made and check access to the Internet. If this does not help, we restore the addresses used by the default router.
Problems with incorrect addressesDNS servers 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 corrected, again, in the protocol settings. Try setting automatic retrieval of required addresses or enter in the column of the preferred DNS server "8.8.8.8", and in the alternative column - "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 the experts with the question “why I can not connect to my WiFi” for you has disappeared!
