After a while, you are informed that there is an authentication problem or you see an authentication error under the name of the network you are trying to connect to. The first thing most people do is re-enter the password, to make sure the password they entered is correct. Unfortunately, sometimes you know for sure that the password is valid, especially if you are still connecting to your home network.
