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:

username@myhostname:~$ uname -a
Linux myhostname 5.4.0-42-generic #46-Ubuntu SMP Wed Oct 21 22:29:16 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

This shows the UNCLAIMED network for the WiFi:

username@myhostname:~$ sudo lshw -C network

Finally solved it! I had to 1. load the correct module, and the missing item that took me days to figure out was 2. disable secure boot. Details below:

For Kernel 5.4, install iwlwifi-cc-a0-50.ucode for AX200, it is available from zip file at https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=2ae99744efc14

cd into /lib/firmware and remove the iwlwifi-cc-a0-60.ucode:

sudo rm -f iwlwifi-cc-a0-60.ucode

then copy over the right one

sudo cp iwlwifi-cc-a0-50.ucode /lib/firmware 

sudo modprobe iwlwifi

if you are facing this error modprobe: ERROR: could not insert 'iwlwifi': Operation not permitted

The solution is to disabled the Secure Boot. Firstly check if SecureBoot is enabled on Ubuntu.

Install mokutil

sudo apt-get install mokutil

and check the status of SecureBoot

mokutil --sb-state

In case it is enabled run command

sudo mokutil --disable-validation

Reboot. Then verify wifi works!

Then, re-enable secure boot again:

sudo mokutil --enable-validation

"Operation not permitted" when trying to `modprobe xpad`

Ubuntu: "Booting in insecure mode" with SecureBoot enabled

Some time ago one of my friend had the same problem, he fixed it by installing an additional driver for his wifi adapter.

He followed these steps

  1. Open Sofware & Updates application, there you will find drivers for your wifi card

Additional Driver Screenshot

  1. Install it.

Comment in this answer if this works for your (it worked for my friend).
