I’ve fumbled through getting this modem on, present in the system, and registered on a cell network.
Now I have no clue how to get wwan0 an IP. I’ve followed the few guides on here and else where and dhclient or the likes just times out on discovery or just immediately exits and the interface still doesn’t have an IP.
I might have broken something, as I originally wanted to use ECM mode and an ethernet bridge to give a router behind it the IP from the cellular ISP. I’ve given up on that as I have no idea what I’m doing, so I’ve gone back to trying to get raw_ip on qmi working.

So after all the problems, I started over with qmicli.

I thought maybe ModemManager was messing something up, so I rebooted with it disabled.
Got a little further than before, but no luck getting an IP.

Just stuck on discover.
What am I doing wrong here?
I would really appreciate someones help getting up to speed on this.
Also I saw theres a /sys/class/net/wwx02360d4c2e4c/qmi/pass_through for qmi. Does this mean I can give the ISP IP to a device behind this modem? I can’t find anything online about a pass_through mode
