Netctl with WWAN on Thinkpad x200 not wirklin

Hi folks,

I got some problem on my new x200 getting the 3g / WWAN connection to work. I set up everything with netctl and created a mobile_ppp profile. Netctl in general is working flawlessly with wifi and wired connections btw.

Here my mobile_ppp profile in /etc/netctl/

When I am trying to connect with "netctl start mobile_ppp" there is no error but I don't get a connection. After checking "journalctl -xn"

Checking the modem.chat this is the output:

What bothers me is that the LED indicating the state of the broadband modem isn't blinking at all all the time. But I also checked with rfkill if its blocked in some way and it is definitely not as rfkill shows me:

1: tpacpi_wwan_sw: Wireless WAN
	Soft blocked: no
	Hard blocked: no

I also tried to google around but didn't find anything that helped me to solve this. The device seems to exist and there is also the virtual net device for the broadband modem created here:

/sys/class/net/wwp0s29f7u4i7

The commented Interface lines in my mobile profile are just leftovers from playing around with different values... This is the best I achieved on my own so far, so any help is much appreciated. The device itself was working on fedora 16-18 without any further setup with networkmanager. But as I decided to switch back to archlinux for different reasons it would be great to have some help getting this bitch to connect as well so I am able to work on the road ;-)
