wifi greyed out after update to ios7
After upgrading from a 100% functional iphone 4s from ios 6 to ios 7.
wifi stopped working. after reboot, wifi setting is greyed out. bluetooth button is shown as busy circle...
done: network reset, backup restore, dfu mode with fresh ios7 file....
turning wlan on in new config bar is available, but does not turn on wifi....
apple diagnostic tool said that I have a charging problem, but everything is fine with charging batteries.
I can not believe that there a so many coincidences with hardwareproblems?
iPhone 4S, iOS 7, Upgrade wifi wlan bluetooth
