WIFI Password is incorrect: Error Message -3900
I have a two second generation Apple TV's.
One recently disconnected itself from the WIFI and whenever I try to reconnect it I get the following message:-
"There was a problem connecting to the internet. The WIFI password entered is not correct. Try Again. (-3900)"
But it has not given me the option to enter a password. It goes straight to the message.
I have reset and restored the Apple TV and deleted it from the list of devices previously connected to my BT Home Hub. On trying to connect it to the WIFI it goes straight to the error message when I select my network without giving me the chance to enter the password.
The only way I have found to get it connected is to remove the security on my WIFI. As soon as I reinstate this the connection drops again.
The other Apple TV is still connected and working fine.
I've tried searching for the error code online without success.
Any suggestions or is it a case of taking it into an Apple store and getting it checked out?
Many Thanks.
