Thinkpad P16s Gen 2 WWAN Fibocom L860-GL-16 under Mint 22 SUCCESS
Raw
README.md

Post by: Hagger Date: 27-11-2024

After days of trying, I finally got the Fibocom L860-GL-16 in my Thinkpad P16s Gen 2 to work, and want to share here how I did it, for all the poor frustrated souls out there that wander on the same dark path as I did.

First - if you havent bought the WWAN card yet, be sure to pick one that is actually whitelisted in the BIOS of your machine. Just being a "L860-GL" is no guarantee that the card will work. Also, your machine needs to be WWAN ready (having a SIM slot and antennas installed), check before buying a card.

The P16s is NOT officially supported by the fcc unlock tool from Lenovo, but I got it working nonetheless. I hope the P16s will be supported in the future, until then you may use this hack ENTIRELY AT YOUR OWN RISK.

On all supported machines, the hexedit part should not be necessary.

This is what worked for me:

  1. Install the card and enable WWAN in BIOS.
  2. Boot into mint 22
  3. Download : https://support.lenovo.com/us/en/downloads/ds563599-fibocom-wireless-wan-l860-gl-16-fcc-unlock-and-sar-config-tool-for-linux-thinkpad
  4. Unpack n3xwp04w.zip, unpack the unpacked lenovo-wwan-unlock_ver2.1.tar.gz, and cd into the resulting lenovo-wwan-unlock directory.
  5. Open fcc_unlock_setup.sh in your favorite text editor
  6. Edit line 15 to say OS_UBUNTU="Linux Mint", because otherwise the installer will refuse to work on mint.
  7. sudo apt install hexedit
  8. hexedit DPR_Fcc_unlock_service
  9. In hexedit, press Tab to switch to ASCII editing, press / to start searching, search for T14, and navigate to the section "Thinkpad T14s Gen 3" with the arrow keys. Then, edit it to say "Thinkpad P16s Gen 2". Ctrl+x to save and exit hexedit.
  10. sudo ./fcc_unlock_setup.sh
  11. reboot machine
  12. In network manager, create a new connection according to your country, LTE carrier etc. AFAIK not all carriers are supported, especially in the US.
  13. Try to connect. It might take a few seconds. If it doesn't work, you can try logging into the Windows 11 that you are hopefully dual-booting and install the WWAN driver there via the lenovo vantage software and try connecting. I suspect this loads the right firmware for your carrier onto the WWAN card. This worked for me. If you aren't able to connect under windows, you probably also won't under Mint.
  14. Leave a comment! I would love to read if you got it working too.

cheers
