Today we will consider one problem that users of smartphones and tablets very often encounter. And in this case, it doesn’t matter which company your device is. It can be Samsung, LG, Sony, Lenovo, etc. It’s about an authentication error when connecting to Wi-Fi.
What is the reason? The reason is definitely not in the manufacturing company. The error itself occurs when you try to connect to a Wi-Fi network on a smartphone or tablet. She says that you most likely incorrectly entered the password from the Wi-Fi network. This problem is easily solved if you are trying to connect to Wi-Fi at home. It’s a completely different matter when it comes to public networks – in this case, it’s unlikely that you can do something, unless you find out someone’s password for this Wi-Fi network.
What the error looks like?
An example of how the error looks.
You turn on Wi-Fi on your device and connect to the network. Authentication occurs.
However, you cannot connect to the network and you see the message “Authentication Error”.
How to get rid of an error?
First reboot the router. Perhaps this is a regular glitch. To reboot the router, you can remove the wire from the outlet for 10 seconds.
If this does not help, you need to check whether the password you entered is correct. To do this, enter it again when connected to the network.
Didn’t help again? Perhaps someone changed the password while you were not at home. To find out, you need to go into the settings of the router. To do this, take the router, turn it over and see a sticker where the details for the connection are written: address (192.168.0.1, 192.168.1.1), as well as a login and password of the form admin 1234. Of course, the data may be different. In addition, if you changed the password from the router, you will have to remember it, otherwise you won’t be able to get to the interface without resorting to resetting the settings.
Next, we type in the browser address (192.168.0.1 or 192.168.1.1) and enter the login information.
Once in the settings of the router, we are looking for the Wi-Fi section where the password should be displayed. In our case, the password is in the Wi-Fi section, the Security Settings subsection. We see the password (highlighted by an arrow):
We enter it into our tablet or smartphone when connected to the network. If it worked, great!
If that doesn’t work, try setting the WPA / WPA2 encryption key type in Network Authentication. In addition, modern routers support various data transfer technologies, including 802.11b, 802.11g, 802.11n. If your device is not designed to support 802.11n (one of the most modern technologies), try installing 802.11b and connecting to the network.
Practice says that most often the problem lies precisely in the password. Now you know where to look for him.
