I have a iPhone 5 and sometimes when I'm on wifi the Internet doesn't work, but a quick discontent and a reconnect fixes it. Now when I'm on AT&T's network it's a different issue. I have attached a pic if it. I could be on the network and it would just fine. But then out of now where it stops working and the network still shows "4G" but doesn't warm me that there is a network error. I try to do the reconnect trick and it doesn't work, in fact the network loses all data connect at all. It does this all the time and it could take a hour for the network data to start to work again. I tuned to AT&T for help but no luck, idk how to report a bug to apple so I came here. If you can help please do.
