iPad 2 wifi turns itself off and I cannot turn it back on
Despite my sig it's actually iOS 4.3.3.
Twice now my wifi will turn off and cannot be turned back in. When you move the little slidy thing it goes to on, says on but on the left still says off. Also the box showing available network will not appear nor the option to 'ask to join networks' option. Needless to say the wifi isn't actually working. The only way to get it working again is to power off and back on.
The first time it happened was moments after I left the apple store. I connected to their wifi, left, went into s Starbucks and tried to connect but it was off. The latest time was after staying away from home and upon my return it wouldn't connect to my home network.
I already use a static address so it's not that and our iPad 1 works fine.
Thanks
iPad 2, iOS 4.3
