Does anyone else have this problem? I am on an iPhone 5s. It works for a bit then the signal drops and then I'm on my cellular. I've done clean installs, reset the router, iOS 7 still works, but I feel like this issue should have been cleared up in this newest beta. Idk if I'm the only one. Not sure if this is hardware related. I don't think I can go into an Apple store or call Apple and see if they can help me. I'm just checking to see if this is happening to other people. I don't know what else to do here.
