Anyone able to fix "Incorrect Password" wifi problem with iPhone 5?

[Ant.honey]

Just activated my phone today. Unable to connect to wifi here at work. iPhone 4 never had/still doesn't have an issue. Internet tells me this is not uncommon. Before I go to the Apple store and exchange it for one that works, anyone had an experience with something they did on their end that fixed this problem? (WPA2)

Try restoring as new before you take it back or reset all network settings then try connecting again.

Never heard of this problem. Try Reset All Network Setting.

I did reset all network settings, multiply restarts and reboots.

I probably only found a millions threads on the subject because I had a particular problem.

I did find a solution and that was to wipe the phone of all it's contents and restore from backup. Worked like a charm.
