The phone can see the network but did not connect with the previously stored password. Re-entering it does not help and it reports (briefly) "incorrect password" at the bottom of the screen before saying "Authentication error occurred".
So, I think this is due to 4.1.2 - I have spent most of the morning looking for a fix and failed. Has anyone found a work around yet?

Same with me, happened in the last few days, with a limited data plan and everything set up to work over WiFi, I need this sorted ASAP
