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

The only way to fix greyed out wifi is to go in iFile and change the wifi property list file. Go to var_preferences_SystemConfiguration and find com.apple.wifi.plist. Open it up with the Property List Viewer and turn AllowEnable on. I hope I have saved you from a trip to the apple store.
