I have a similar problem on the X1 Carbon, running 12.04, trying to connect to a Vodafone contract mobile broadband
My symptoms are: mobile broadband is always disabled; to connect I first enable it, then click on the Vodafone connection to activate it. Most of the time it fails to connect. I do sometimes get a working connection, but in a minute or two it kicks me off. Below what I get in syslog if I use nmcli to start the connection via nmcli -t con up id 'Vodafone Contract' Jun 6 11:00:03 hc-x1 NetworkManager[1016]: <info> Activation (ttyACM1) starting connection 'Vodafone Contract' Jun 6 11:00:03 hc-x1 NetworkManager[1016]: <info> (ttyACM1): device state change: disconnected -> prepare (reason 'none') [30 40 0] Jun 6 11:00:03 hc-x1 NetworkManager[1016]: <info> Activation (ttyACM1) Stage 1 of 5 (Device Prepare) scheduled...
