I could not join the network with iPhone 5.
It started 2 days ago all of the sudden. I tried all the methods on the support website but in vain. Other family members or friends using iPhone 4 have no issue connecting at the same time. Is the update I have downloaded messed up network connection? I reset the network settings and erase all the settings. I still could not join the network automatically. Please help.
iPhone 5, iOS 6.1.3
