Bought an Acer tablet. Cannot connect to my Wi-Fi, it says Authentication problem. Please help!

Solution
Authentication problem means you are either trying to connect to the wrong WiFi with the password to another one, or you are inputting the wrong password for the right WiFi.

Try first verifying your password for the WiFi, then forget the connection on the tablet and make sure you turn on the option to see what you type when you enter the password for the WiFi.
