  • IPhone 5 Wi-Fi not working after ios 7 update? Ever since I got the ios7 update for the Iphone 5 when i usually connect to the Wi-Fi automatically, now it makes me manually go to Wi-Fi settings and find it. When I click on it it tells me to enter a password which shouldn't happen anyway but even stranger is when I put in the password it tells me its wrong. I'm 100% sure and have triple checked that its right and I know ios7 had something to do with it. Either way someone please help!
