Hi. I am having the same issue on a brand new Ipad. WIFI won't connect. I re-booted a few times.
I do have a laptop and a Droid which connect instantly on my wifi network. My network is WPA/PSK2.
I tell the IPad to even "forget" the network so i can manually add it. It won't. The Wifi icon appears but when I browse or get email, it says I am not connected.
