I’ve got a desktop that I’d like to have wireless to, and dum dum here decided to get a card before I looked up whether Linux supported it out of the box. I tried installing the official package rtl8812au, but that did nothing. Then I tried to source install the rtl8812AU-rtl8821AU from Home:Saurland:Hardware. The source package itself wouldn’t seem to install, at least I couldn’t verify it. Then when I tried to install rtl8812AU-8821AU-kmp-default, it would lock up my desktop on boot! If I can’t get this wifi card to work, it’s not the end of the world, as I found a list of cards that are supported natively, but if there’s a fix I’m just not seeing that’s not going to be a hassle every time I update (I’m looking at you, dkms), then I’d be willing to try.

Then when I tried to install rtl8812AU-8821AU-kmp-default, it would lock up my desktop on boot!
No driver installed?
The driver has no update for more than 2 years…
I will see on weekend if I get some other source working…
Sorry to cause any confusion. I rolled back my system to before I installed the source package once I learned rtl8812AU-8821AU-kmp-default broke my desktop
So dkms isn’t as evil as I thought it was. Using the driver from GitHub - aircrack-ng/rtl8812au: RTL8812AU/21AU and RTL8814AU driver with monitor mode and frame injection, my wifi adapter now works
