After having the phone since launch, about a week ago the Wifi just stops working. I turn it off...back on...off...back on, but it doesn't get any Wifi signal. The only thing that works is restarting the phone. It's not my router, because there are about 20 Wifi signals to pick up around my house and it won't get any of them. It does this about daily now. Any one else with this issue? I have not reset it. Waiting for 8.1. Oh, in the screen shot, it just searches for signal forever and never finds any. Like I said, until I just restart.
