Whether it's the iPad (4th Gen) being powered off or reconnecting to my home WiFi router (after using a free WiFi hotspot) , I have to reenter the home network password. I've tested my network with a friends iPad 2 and my old iPad 1, and they do not require the password. And yes, all 3 are set to automatically connect, but it's just the iPad 4 that keeps asking for the password.
