I've had my kindle for about 5 months now, and the wifi was completely fine, until today.
So i clicked onto my wifi and it had a lock on it so i typed in the password for it, (it turned out to be the wrong password) so it said 'Authentication failed' im guessing it's because i typed the password wrong. How do i retype it? it says signal stength very good and when i try to connect it it loads for a while and then says it failed.
