iphone 5 wont stay connected to wifi
My iPhone 5 keeps dropping wifi connection after about 30 seconds of being connected. It's not my router or internet because we bought 2 phones and the other phone works and stays connected just fine. It's only my phone. It tries to connect to a website, youtube, email, whatever and then just times out. If I attempt to renew the lease it renews with some strange IP address that isn't tied to my router and leaves the Router and DNS fields blank. I have reformatted, reset network settings, reinstalled the OS, forgotten the access point and re-entered, changed the wifi channel for troubleshooting steps so far. Any further ideas other than a bad antenna?
iPhone, iOS 6
