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:

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:
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
