I just bought a new machine and put the latest Ubuntu on there, and cannot see my WiFi. nmcli showed only localhost and ethernet... no WiFi at all.

I've searched high and low, and at least have found the commands that I can run to hopefully help you help me ;)

Looks like it's getting error code -110 on iwlwifi, and the commands I ran show that the network is UNCLAIMED, not sure if that's a clue.

UPDATE: I downloaded the AX200 driver from https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-i-o/wireless.html and cp'd the file into /lib/firmware, and followed How to load iwlwifi driver?.

UPDATE 2: I reinstalled Ubuntu with "Install 3rd party software for graphics and wifi hardware" checkbox... still no dice.

UPDATE 3: Re-installed 20.04 (to avoid issues w 20.10) and still all the same issues.

Any help greatly appreciated!

Here is the dmesg to give us some clues:

username@myhostname:~$ sudo dmesg | grep wifi

[    4.935758] iwlwifi 0000:06:00.0: enabling device (0000 -> 0002)

[    5.015538] iwlwifi: probe of 0000:06:00.0 failed with error -110

 

Here is the lspci info to get the hardware info:

username@myhostname:~$ lspci -knn | grep Net -A3; rfkill list

Here is the uname info:

This shows the UNCLAIMED network for the WiFi:
