New wifi 6e card is not working

Unfortunately, both new* tech and WiFi drivers are weak points for linux, and you've run into them together on a single device.

*not just brand-new-bleeding-edge, but linux tends to lag a couple years behind on supporting specific pieces of hardware not covered by more generic drivers.

Quick confirmation: do you mean AX211NGW? I can't find any info on an AC211NGW. Also, your console output shows AX201 which is a WiFi 6 chip, not 6E.

Both Intel and kernel.org list the AX201 and AX211 lines as compatible since kernel versions 5.2 and 5.14 respectively.

This post is designed to provide some troubleshooting steps which tend to resolve the more simple device / driver issues I've come across, and group together the basic information gathering steps to help people write meaningful requests for help if those steps don't resolve the issue. 1.

EDIT

Forgot you already tried the backport drivers so removed that suggestion.
