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'
