The adapter you got should work fine, with the proper driver. I went to their driver download page, and got this archive for Linux Kernels: 4.19 - 5.11. Inside the archive, found the README.md file pointing to a github repository that contains newer versions of the driver https://github.com/morrownr/8821cu-20210916. You should give it a try.

if you want to make sure this is the correct driver for your adapter before going through the rest of the process, you can run the command lsusb. the id's will look something like 0BDA:B82B. the list of supported device id's is on this page: https://github.com/morrownr/8821cu-20210916/blob/main/supported-device-IDs

If your linux kernel 5.8 or higher you can try to use this driver https://github.com/morrownr/8821cu

I managed to make my wifi to work thanks to the advice from u/marvelggg getting the drivers for my new wifi card here. https://github.com/morrownr/8821cu

I always had two problems on all linux distros (including previous versions of elementary): no wifi or sound. The wifi driver needed is the rtl8821cu realtek driver. I followed the instructions for 'Ubuntu and derivatives' in the README.md but got this error (These exact steps worked ine in the previous version of elementary):

Hi everyone! My rtl8821cu wifi adapter doesn't work on Artix Linux (runit). I've installed this driver via dkms, I also tried to install rtl8821cu-dkms-git package from AUR but it still doesn't work.
