Hi again Peter S,
Good to hear you have found the problem with the GPS and got things working.
If this was a WiFi only iPad, this is correct behaviour, (as Steve has posted). Your device is telling you that you have no access to 'External Internet' as your iPad WiFi is already connected to PilotAware, which only provides a 'Closed WiFi Access Point' between PilotAware and your device with no External Internet Access.
As it is a 3/4G iPad, however, it 'should' still be possible to connect to the internet via 3/4G (if you have a signal), but my iPads don't have sim cards so I can't remember, but think there are some settings you need to change. (Can't remember what though - Sorry!) I'm sure some of the others can help.
Regards
Peter R
