This problem just started last night for me. My HTC DNA all of the sudden won't connect to WiFi. It just says 'Turning On" on the WiFi screen, but it never actually activates. I have reset the phone multiple times now, pulled the sim card out and put it back in and still it won't connect. As far as I know there were no system updates or new apps downloaded yesterday. I really didn't even mess with my phone yesterday. I'm trying to figure out if I can fix this or if I need to go to the Verizon store. Thanks
