Problems with WWAN Under Ubuntu ( X1 Carbon )

[aspen]

I've got an X1C, and appear to have borked the 3G at some point.
I tried it once with my T-Mobile SIM right after I got it, and it worked fine. Then I got an AT&T data plan.
Settings aside, here's what happens when I try to connect (syslog):

Code: Select all

The concerning part about this is the:

Sep 21 13:12:33 twelve NetworkManager[1049]: <warn> GSM connection failed: (32) Sending command failed: device is not enabled

I have the box ticked in Network manager... I did at one point install gammu so I could get the IMEI off of it. I'm thinking maybe that accidentally changed a setting?

disable network manager completly.

start minicom with
minicom -D /dev/ttyACM0
AT+CFUN=1

start wvdial and set it up properly. If you put AT+CFUN=1 in the Init1 line please don't ask me how to fix it

There's a very good guide for the f3507g card which describe it deeply.

Google for 'Thinkwiki f3507g'

It's probably not the same card you have - but possibilities are that your card use the same AT commands.
(And no - i don't know what 'AT+CFUN' means, but probably CFUN means 'CONNECT FUN')

Take a look to the command "rfkill", I detected that network-manager used to get stuck with wifi on my x301. It could be possible it happens also with WWAN.
