rtl8814au VS rpi-source

dkms helps with keeping a module working across Linux kernel upgrades (I use RTL8812AU, but RTL8814AU is problematic [1] being broken. I also use dkms + ZFS on Proxmox and Ubuntu), but other than that don't upgrade Linux kernel, unless you have to. I guess OpenBSD doesn't include the binary blobs, but back in the days (about 10-15 years ago) I used to have a stable WLAN on OpenBSD, on a Soekris. This was 802.11n (later rebranded WiFi 4), I don't now about 802.11ac / WiFi 5. Worked perfectly fine. IIRC it was either Atheros or IWL.

The driver hasn't been updated yet to support your Linux kernel version. Any one below 5.9 is okay, so you should downgrade to 5.4 as that the latest Long Term Support kernel below that.

Has anyone been able to make this work? Before 21.04 release, I was using this method and it worked, but not anymore.

I'm trying to install this on Pop! OS using this GitHub.Link. But it's simply not working. It was working for Kernel before 5.13.

I have also followed this afterwards https://github.com/aircrack-ng/rtl8814au/issues/32

You can use apt full-update and that should push you to the correct kernel. This page has also helped me in the past.
