I have just upgraded my netbook from XP to Windows 7. The netbook has a datacard installed with an XT SIM and with XP I used the Dell Connection Manager to establish the connection.
Windows 7 seems to support mobile broadband connections natively and I am notified by an icon in the tray that the network Telecom NZ has been detected, but when I click 'Connect' it fails to connect.
I swapped out the XT SIM with a vodafone SIM and Vodafone network was detected and it connected when I clicked 'Connect' and I was able to browse the web (seemed to automatically pick the right APN as I didn't have to enter it).
Has anyone else got this working with XT? Is it possibly a 3G issue? As the Vodafone connection was maybe not 3G (I live out in he country and I don't think there is a 3G tower near by?).
I haven't been able to find a version of the Dell Connection Manager software for W7 so hopefully I can get this working without it.
