Fibocom L850-GL installation on Ubuntu 20.04 or 21.10

Question

I have a Lenovo ThinkPad X1 Nano Gen 1 with the Fibcom L850-GL 4G LTE CAT9 module.

I found some information how to install it here, but id does not work. Since I cannot comment or answer here a new question.

• This solution gives me errors (incompatible pointers) while compiling: https://github.com/xmm7360/xmm7360-usb-modeswitch
• This one ends up with a message INFO:root:IP address couldn't be fetched, waiting 1 seconds https://github.com/xmm7360/xmm7360-pci
• Here I got also an error while compiling (-Werror=implicit-function-declaration) https://github.com/juhovh/xmm7360_usb

Unfortunately, I don't really have a clue what I'm doing. But as I read, the module should work. Some ideas how I could do this?

Edit: Tried it on Ubuntu 20.04 and upgraded now to 21.10, with the same result

Answer 1

https://github.com/xmm7360/xmm7360-pci is the correct one you look for. The m.2 slot in every Thinkpad since I think 2019 or so only supports PCIe and not USB mode anymore.

The IP address error - check if the APN is correct, no PIN and all WIFI is disabled.

Similar questions can be found on Github and one post had it working with X1 Nano. https://github.com/xmm7360/xmm7360-pci/issues/114

Good luck!
