I gave me old i4 to my fiancé, and she's been having wifi issues sometimes. Usually she'll just turn off the phone and turn it back on and it's working again, but last night that ol' trick didn't seem to work. I told her to toggle wifi back and forth, reset network settings (now that I think about it, I guess that wouldn't affect wifi anyway?) and nothing... I know there have been some reported wifi issues with iOS6, but I thought maybe they were just on iphone 5. Anyone have any ideas?
