Just replying to document my wifi experience. Not fully robust and definitely quirky. I connect to many different wifi networks (tmobile, home, airports, etc). I've noticed two issues:
(1) wifi will turn itself off and I can't turn it back on. I can slide the setting to on and when I select another setting and return to network, the setting goes back to off automatically. The fix is to shutdown and relaunch the settings app (or shutdown the whole iPad).
(2). The iPad will not connect to a network even though it shows as connected in settings. All correct network parameters were retrieved via dhcp etc. Renewing the lease, turning networking off and on and restarting the settings app do not work. The only fix is to fully shutdown the iPad and restart.
