Intel Wi-fi 6 AX200 adapter not found on Ubuntu 20.04

The wifi settings page complained that no wifi adapter can be found. here's some relevant information

lshw -C network *-network UNCLAIMED description: Network controller product: Wi-Fi 6 AX200 vendor: Intel Corporation physical id: 0 bus info: pci@0000:04:00.0 version: 1a width: 64 bits clock: 33MHz capabilities: cap_list configuration: latency=0 resources: memory:fc600000-fc603fff

i also tried to follow the instructions on this page and also downloaded the firmware file from here and copied it over to /lib/firmware

i also tried to boot in insecure mode but doesnt work either.

FYI, my kernel version is 5.4.0-42-generic and I'm running only ubuntu 20.04 on my PC (not dual-booting)

Does anyone know of a solution to this problem?

I had the same issue with AX200 (rev1a). I have a dual-boot (Windows 10, Ubuntu) and I turned both Fast Boot and Secure Boot in BIOS off, but the Wi-Fi still didn't work. After running the command:

sudo dmesg | grep iwl

I saw an error:

failed with error -110

And I found in a conversation, that I need turn off Fast Boot in Windows too.

It helped me. It was a lot of time.

I had the same thing and tried a lot of different fixes. What i think fixed it was updating my kernel.

wget
chmod a+x ubuntu-mainline-kernel.sh
sudo ./ubuntu-mainline-kernel.sh

I restarted the PC and it didnt initially work so i turned the machine off. When i turned it back on in the morning, the wifi was back!

Im now running the following kernel and the wifi seems to be reliable.

#~ uname -r
5.8.0-050800-generic

The error i was getting was something about failing to load the module -110. Now i get the following:

Some of the other things i tried were making sure i didnt have the hardware switch on and removing/reloading the kernel module:

sudo rmmod iwlmvm
sudo rmmod iwlwifi
sudo rfkill unblock all
sudo modprobe iwlwifi
sudo modprobe iwlmvm

I tried installing the driver direct from intel - But that didnt seem to work.

I tried installing the backports as well but again, that didnt seem to work for me.

sudo apt install backport-iwlwifi-dkms

In my /lib/firmware, i have a lot of iwlwifi ucode files now....

So if updating the kernel driver dosent work, try those other things.

I found that when i updated my kernel driver, i had to switch my nvidia graphics to the open source driver as well as the kernel update seemed to break the graphics so that i couldnt connect external monitors. I did this through the UI by selecting Additional Drivers -> Using NVIDIA driver metapackage from nvidia-driver-450 (open source)

(Previously it was on 440-proprietary)

After disabling the "Fast Startup" the issue got resolved for me.

Thanks

You can update the intel backports and wifi driver using this. It will update the kernel needed for the wifi driver. It worked for me

sudo add-apt-repository ppa:canonical-hwe-team/backport-iwlwifi
sudo apt-get update
sudo apt-get install backport-iwlwifi-dkms 

If I ran inxi -Fxz it would show no driver for my Wi-Fi.

I had a new computer and had only booted into windows once. Used my Linux for about three days and then had switched and came back to Linux to find no Wi-Fi. It was as @IncSaint mentioned. Basically, Windows fast boot doesn't shut down all the way and saves some stuff to memory, interfering with Linux setup for Wi-Fi. The answer was to turn off fast boot.

on Windows 10 it should be in “Control Panel→Hardware and Sound→Power Options→System Settings”. Select “Choose what the power buttons do” to access the System Settings from the Power Options. Then disable the “Fast Startup” option in “Shutdown Settings”.

My access was slightly different - choose what power buttons do was in power options.

About dual-boot with Windows and "fast-boot" enabled

I tried a lot of solutions such as disabling fast boot, disabling secure boot, updating kernel and etc...

What finally worked was upgrading my Ubuntu 20.04 to 21.10.

May it will help someone

My wifi adapter on Ubuntu 20.04.3 LTS sometimes also not working. Just tried turn-off (restart not working), unplug source cable from power supply(only turn-off-on also not working), turn-on without electricity, plug in source cable to power supply and turn-on. It is weird but wifi is back. I was motivated to do this, because I read and also experienced that after turn-off PC at night and turn-on at morning wifi was working.

If any of y'all are dual-booting with Windows, you may need to add a registry key to use UTC time in Windows. Running Zorin OS 16.1, also ran into the same issue in PopOS, both of which are Ubuntu-based forks. Seems to be some sort of clock synchronization issue.

The below link has instructions.
