I am at a complete loss. I would call a snake charmer at this point if I thought it would work. My first iPad Mini worked great on my home network, but would not connect to my work network. Mind you I have a Kindle Fire, my wife has a Kindle Fire, two computers, my iPhone 4s and my wife's iPhone 4s that connect to everything fine. Apple told me with the first Mini, 'Take it back'. So I did. I have had this second iPad Mini for a week. It worked fine....for a week. I was surfing away Sunday night downloading books on my Kindle app. Got tired and went to bed. Next morning: it wouldn't connect to wifi, no way no how. I reset the network settings. I shut bluetooth off. I rebooted my router (even though all my other things connected). I changed security on my network. I changed the name of my network. I restored my iPad Mini as though it was new......couldn't connect to wifi. I've litterally tried everything. I have been on the phone for hours with Apple they are baffled, but one told me that they were aware that there was a problem and were not sure if it was software or hardware. I guess we are going to have to wait from almighty Apple to find out. This *****! Oh and it wouldn't connect even at a McDonalds where they have unsecured wifi. :( If anything works for you or you hear anything I would appreciate the help. Thanks!
