Why does my wifi selection has an Authentication problem?

Solution
Authentication problem means you are either trying to access the wrong hotspot/WiFi with the password for yours, or you are entering the wrong password for your own hotspot/WiFi. So you need to check that you are 1. trying to access the right hotspot/WiFi and 2. entering the correct password.
