Wifi Adapter doesn't work/ drivers - AWUS1900 RTL8814AU

Can’t get my wifi adapter to work. Adapter is Alfa AWUS1900 rtl8814au.

Tried the two available AUR packages:
rtl8814au-dkms-git
rtl8812au-aircrack-ng-dkms-git

Also trying installing from github:
aircrack-ng/rtl8812au
morrownr/8814au

Following their install instructions often leads to errors related to libs or kernel:

sudo make dkms_install
grep: warning: stray \ before #
grep: warning: stray \ before #

Spent hours on this. Anyone know how to handle this?
How to properly install the drivers and make the adapter ready to connect?

I’m familiar with Linux but not an expert by any means, so all help and suggestions are appreciated.

Rtl8814au-dkms-git was working before kernel 6.13. I can confirm I had to downgrade to 6.12.10 in order to bring back my USB dongle.

Try rtw88-dkms-git.
More or less, all RTL88xx drivers goes here and slowly upstreams from this repository to kernel.

Re: Wifi Adapter doesn't work/ drivers - AWUS1900 RTL8814AU

Hey there. I'm reasonably new to Arch, so read my name.

Using yay to install AUR packages(if you don't, well there's the name of the AUR package), the code I recommend is:

 yay rtl8814au-dkms-git 

My case is rtl8812, but I've been using Morrownr's drivers(github) for a while, and usually without any issue.

Good luck, and I'd do a reboot after installing....
