iPhone 4S cannot scan for wireless network since yesterday and i was using WiFi perfectly
So yesterday i was using iphone browsing internet, playing games, etc. And in the evening i unlock the iphone and didn't see the wifi status on the status bar. I click setting menu and it took around 30 seconds to open it, and i click wifi, the little ball keeps spinning but none of networks show up, i try to join the net work nanually, but when i click join, it says "Could not scan for wireless networks". At first i thought this is a hardware problem but when i look up my question on the internet a LOT of people appears have the same problem, and some of them said they did not had any wifi scan problems in ios 4 but after they upgrade to ios5 they had this problem.
My iPhone 4S is broght in April 2012, comes with ios5.1
Thanks A Billion!!! please save me~😐
iPhone 4S, iOS 5.1.1
