new ipad doesn't remember wifi password after update to ios 6

So I updated my new ipad to ios6. Now it won't remember my wifi password. Wifi works ok, but if I turn off wifi and turn it back on, it won't connect to it unless I go in and put in the password again. I've done a erase all contents and settings, I've done a reset network settings, nothing has fixed it. My wifi reconnected just fine on 5.1.1. Any suggestions?
