Thinkpad p14s, and bluetooth works. From what I can tell, the wifi should "just work" for this kernel version, so not sure what i'm missing. Also, the wifi worked before a recent ubuntu update I installed. I reinstalled ubuntu but it's still not working.

Another weird thing, I am using ethernet (because no wifi), but it is 20x to 30x slower than the same ethernet connection when booted in Windows. UPDATE: toggling bluetooth fixed this??

  • I've disabled fast boot
  • I've disabled secure boot
$ dmesg | grep iwl

I've restored wifi functionality. The solution found in this this email thread worked:

https://www.spinics.net/lists/linux-wireless/msg209307.html

As per that email, removing this file and rebooting restored wifi functionality:

sudo rm /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm

This bug report gives from March gives some context: https://bugs.gentoo.org/777324
