Wifi will not switch on in iPad settings.
My iPad will not switch on wifi in settings . I've tried resetting internet settings and resetting all settings but the blue wifi switch does not exist! My router is working fine with my MacBook Pro. I was in the middle of downloading the latest ios8 and it hung midway. don't know if this is a clue. I had problems getting the iPad onto the net before this and solved it by resetting internet settings but this will not work now. The iPad is looking for the iOS update but cannot access it as the network settings do not work. Any ideas?
iMac (27-inch, Late 2012), OS X Yosemite (10.10.4)
