I was having issues with Ubuntu 20.04 LTS. I could not connect to the internet. The only way I was able was through connecting my phone to my laptop so that my laptop could share off the wifi. When I looked at the wifi menu in settings, the menu would say something like, "Adapter not found".
SOOOO....
I decided to try Kali. I was eventually able to get Kali up and working, but same exact deal as Ubuntu.
I'm assuming that this is happening across both OSs because they both run off of Debian. I've also done some digging through other posts on this very topic and it appears that this is the problem. I've tried following dozens of posts, but none of them have worked.
I think that because the Intel Wi-fi 6 AX201 is relatively new, Ubuntu and others have not yet built native support for it.
When will native Wi-fi 6 AX201 compatibility come to Ubuntu?
sudo modprobe iwlwifi
and also:sudo dmesg | grep iwl
