My wife is having problems with her iPad 2. We are traveling the US and many places we eat or stay does not work with her iPad 2. By this I mean her iPad 2 does not see the hotspot that her iPhone 4S, my iPhone 5, my iPad 3, my MBP retina and her HP laptop will see and connect with perfectly.
I have tried:
Turn Off her iPad.
Rebooting / resetting her iPad.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network. <== Network cannot be seen
Her iPad 2 however will still not see the WiFi.
No luck with any of these:
