iphone 6 ios 8.1.1 wifi problem
i bought 2 iphone 6 comes with ios 8.0.2... wifi dropping and switching to 3G continuously in any place even in my home, i try to updated to ios 8.1.1 with itunes but still having the same problem. i did everything i read about this like , updating my wireless firmware, resetting my iphone network settings, reset and delete all contents, restore to factory with i tunes, sometimes the wifi appears on the top but when i try to use internet it did not and switching to 3G and connect. sometimes asks me to put the wireless password many times to identify again. it goes crazy, i got 3 ipads(3,4,mini) with ios 8 and iphone 5 (ios 7) without any wifi problem on the sames wireless.
do u think its software or hardware?
iPhone 6, iOS 8.1, IOS 8.1.1
