Ubuntu 20.04 with kernel 5.11.0-40-generic does not recognize intel wi-fi 6E ax210 160mhz

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

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
