Under experimental settings you've got your gmail address and password inserted?
Check, on your ipad, to make sure that the ip address of your away jives with the ip address that the desktop shows as your Splashtop ip address and make sure the port number is the same. I did this on mine by turning my wifi off at home to check to see if it would connect to 3g.
Also on away it also took several tries before it connected once the ipad found my computer.
You might have to manually add your desktop on the ipad. On the Splashtop home screen tap the + and add the credentials
On the ipad main Splashtop screen, upper right, the*symbol, internet discovery, is that stating "signed in"?
