I just came from a 4S to a 5, and I have a question about wi-fi. I am on wi-fi at home, but when I leave home and then return, the phone will not show the wi-fi symbol until I actually do some kind of action with the phone. In other words, if I return home and lay the phone on a table for a couple of hours, it will not be showing wi-fi, until I do some kind of action with the phone. Is this a symptom of the wi-fi bug, or is it normal? I never had this to happen on my 4S.
