Hi list,

I still have problems to get the modem connect to the net.
libqmi and libmbim are compiled from the qmi-over-mbim branches.

sudo qmicli -v -p -d /dev/cdc-wdm0 --device-open-mbim
--dms-set-fcc-authentication works and gives me

Nevertheless when I try to connect with network manager, it gets a local IP:
[rallo at six ~]$ ifconfig wwp0s20f0u2i12
wwp0s20f0u2i12: flags=4291<UP,BROADCAST,RUNNING,NOARP,MULTICAST>  mtu 1500
        inet  netmask  broadcast
        ether aa:52:d6:06:f1:06  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 17  bytes 2285 (2.2 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

[rallo at six ~]$

What is going on here? Is there anything that I can do to analyze this


Kind regards,
