WWAN Ericsson C5621 TFF

Hello,

I've got some problems while connecting with my Ericsson C5621 TTF WWAN card in my notebook. The netctl configuration:

Description='Example PPP mobile connection'
Interface=ttyACM0
Connection=mobile_ppp

# Use default route provided by the peer (default: true)
#DefaultRoute=true
# Use DNS provided by the peer (default: true)
#UsePeerDNS=true

# The user and password are not always required
#User='example@yourprovider.com'
#Password='very secret'

# The access point name you are connecting to
AccessPointName=pinternet.interkom.de

# If your device has a PIN code, set it here. Defaults to 'None'
Pin=MyPin

# Mode can be one of 3Gpref, 3Gonly, GPRSpref, GPRSonly, None
# These only work for Huawei USB modems; all other devices should use None
Mode=3Gpref

The journalctl output:

IIRC it worked in former times, but today it doesn't work anymore. And when I try to execute the at commands directly by using PuTTY it also doesn't work. AT+CFUN=0 works, AT+CFUN=1..3 doesn't, but AT+CFUN=4 works again. On windows I can connect to the network. Can someone help me out with this?

Kind regards,
Daniel
