I got my iPad 4 from Santa and just love it!
But here's my problem: I can connect to my own wireless router here at home without any problem. The other day I was at a friend's house and tried to connect to his wireless router I couldn't, and yes...I was using his correct password. It was the same at my local coffee shop.
My iPad sees the network in the wifi settings and prompts me for the password. I enter it but the "join" button is greyed out. What do I have to do to be able to connect to other networks besides my own?
Thanks in advance,
