My iPhone 5 is not picking my wifi signal but my iPod touch 5 is. I am in a room with thick walls and my iPod Touch 5 has 2/3 bars of wifi strength. My iPhone 5 sometimes picks up the signal with 1/3 bars. Does the iPhone 5 have a wifi chip that is worse than the iPod touch 5? Help iPod touch: iPhone:
Have you tried resetting your networks settings? iOS 6.0.2 is out for the iPhone 5, supposed to fix wifi issues.
Had the same problem. They said it was normal when I brought mine in for the very same issue after trying all of the afformentioned fixes.
