Dannel Albert, if you're able to find a way to downgrade your kernel version to something that's at least 5.11.0 (the version which added support for the AX210), but older than 5.11.3 (the version which broke it), then I would recommend trying that.
I'm not an arch linux user myself, but downgrading the kernel in fedora by manually downloading & installing older kernel packages was a good temporary fix for me.
I'm not sure what the etiquette for providing help/workarounds on kernel bug reports is, so I apologize if this post is out of line and/or spamming everyone :)

Since it seems like you're on arch, maybe you could download linux-5.11.2 from https:/ /archive. archlinux. org/packages/ l/linux/ and follow https:/ /wiki.archlinux .org/index. php/Arch_ Linux_Archive# How_to_ downgrade_ one_package to downgrade?
Or maybe it'd be better to follow what the person making the arch report (linked above) said, and downgrade linux-firmware to 20210208.b79d239-1 from https:/ /archive. archlinux. org/packages/ l/linux- firmware/.
