Hi Guix,

Hopefully someone knowledgeable with these things here can help out. :)

I'm trying to get the internal 3g modem to work in my Dell laptop
running guix.

Ideally with networkmanager/modemmanager would be great.

Using nm-connection-editor and selecting mobile broadband, it says
can't find any device.

Creating the connection manually and running it says:

ds@swift ~ $ sudo nmcli con up modem-internal
Error: Connection activation failed: No suitable device found for this connection.

Creating this file and trying to start the connecting with mbim-network results in this:

ds@swift ~ $ cat /etc/mbim-network.conf
APN=internet

ds@swift ~ $ ll /dev/cdc-wdm1

I think this is the internal modem device:

It seems from the above it's /almost/ working using mbimcli.

I'm not sure why MM doesn't detect it.
