Yeah, this worked (like a charm). So I've done:

   1. `# qmicli -d /dev/cdc-wdm0 --dms-set-fcc-authentication`
   2. `# mbimcli -p -d /dev/cdc-wdm0 --set-radio-state on`
   3. `# mbim-network /dev/cdc-dwm0 start`
   4. `# mbimcli -p -d /dev/cdc-wdm0 --query-ip-configuration`
   5. `# ip address add 10.110.6.66/30 broadcast + dev ww<...>`
   6. `# ip route add default via 10.110.6.65 dev ww<...>`

Step (6.) presents me:

Error: Nexthop has invalid gateway.

I suspect I need to say `# ip link set ww<...> up`, am I right? A
transcript of `# ip addr` is attached, captured right after step (5.) above.

Best,
Friedrich
