Hi,

Linux 3.6.8-1-ARCH #1 SMP PREEMPT Mon Nov 26 22:10:40 CET 2012 x86_64 GNU/Linux
extra/networkmanager 0.9.6.4-1
extra/modemmanager 0.6.0.0-1

The initial "connection" seems to work as i can see the signal quality of the mobile broadband connection in network manager. But i can't login with my profile.
Is this (Invalid error code: 277) a known problem with modem-manager?

My O2 profile:
Number: *99#
APN: surfo2

Re: WWAN problems: ThinkPad X220 [F5521gw]

In my past experience using cellular modems from Sierra Wireless, there could be a couple of ports (i.e./dev/ttyACM0) that connect, but only one that works properly.  It is possible that you are using the wrong port.  I am not familiar with your particular modem to be more specific.

In Fedora, where I have used Network Manager before, there is a setup tool ( system-config-network )that you could run from terminal as root, that sometimes resolves issues.  Not sure if arch has this available or not.

As an alternative, you might try using wvdial instead.
