Aircard USB Modem doesn't work on SUSE 11.1

[Guillermo Lloreda Diaz <glloreda bivapr net>]

I have installed Suse 11.1 and at the end the installation  showed an error saying: 'No Network running' I hit OK and the installation continued until the end without any problem. On booting I notice that that the USB Aircard was detected correctly and was setup axactly as it did on Suse 11.0 but when I tried to connect to the Internet Netmanager stalled, no connection at all. It does not do anything.'

I ran '/usr/bin/lsusb' and here is the result: bus 002 Device 003: ID 1199:0120 Sierra Wireless, Inc AC595U.

I don't know what to do ,please help
