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

Question

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

lshw -C network

i also tried to follow the instructions on this page https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/core_release and also downloaded the firmware file from here https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi 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?

Solution 1

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.

Solution 2

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

wget https://raw.githubusercontent.com/pimlie/ubuntu-mainline-kernel.sh/master/ubuntu-mainline-kernel.sh
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:

#~ sudo dmesg | grep iwl

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 - https://www.intel.co.uk/content/www/uk/en/support/articles/000005511/network-and-i-o/wireless-networking.html 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)

Solution 3

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

Thanks

Solution 4

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 

Solution 5

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.

Same for me. Needed to disable windows fast boot. Then Wifi was back. Problem occurred after new Bios was installed. Machine: Intel Nuc 9 Extreme Laptop Kit. Remark: Additionally the Keyboard backlight vanished. This needed a new windows software (gamer keyboard), then backlight worked properly again after setting once with new software. All started with windows system update installing new Bios…

thanks a lot, you save my life. Turn out it related to Windows, not the Linux or ubuntu itself, thanks for your solution

Thanks a lot! You saved my day! I did an automatic update on my laptop and after a restart my WiFi (internal Intel WiFi card) was gone. I tried reinstalling the backport-iwlwifi-dkms and tried some other suggestions. But only the kernel update did the trick. My kernel before was 5.13.22 and now it's 5.15.4.

Thank you for this. You saved me alot of time.

I'm facing a relevant issue (much of which may be attributed to GitHub). Last sudo apt update/upgrade included a 3rd kernel (2nd kernel update) removed 100% networking function. BUT: Because I've no internet function by NIC/Wifi I can't do as suggested. I then tried downloading that kernel you said in Windows 11, (3x) Android 10 on 3 devices, 2 Nokia N900's, 1 Nokia N9, 1 BSD os, a live USB Debian system but all resulted in 0 ability 4 direct download as well as wget for those which can. The download appears to need to be done from within the system w/ no internet access (making it impossible

[Admin]

It's strange that GitHub removed that 1 button to download the file before your eyes. If it were still there I could do so in any of the systems & copy the file to the 2 Ubuntu OS's with 0 IP function (after kernel update to both).
