Hi. I have a problem since I bought my iPhone 5 it can find wifi only when I'm very near to the router( about 1 meter ). I tried to restore it, rest network settings, restart it, update it to the iOS. But it doesn't work. I heard that iOS 6.0.2 will fix it but doesn't work too. I hope it's not a hardware problem, anyone have any ideas about this please take a minute and tell me.
