I just got the refurb iPhone 5 (coming from iPhone 4s) and I'm just having a really odd issue. I can't seem to see any wifi, except for one with 5GHz band. Even when I was activating it at AT&T, the CSR was stumped as to why the phone couldn't see any wifi. Somehow she got it to activate without wifi or itunes so I thought the problem was fixed, but alas I came back home and I cannot see my or anyone else's wifi. Wondering if anyone else had issue with this. I already reset the phone, reset the network, flight mode, and turned on/off wifi. I've already googled to see if there are similar issues but I couldn't find any. Perhaps I just missed it but I'm hoping someone here has an answer. Thanks!
