Thanks @raicabogdan
FYI: Kernel 6.4 has an in-kernel driver for this chipset. Installing this driver with install-driver.sh will blacklist the in-kernel driver and remove-driver.sh will remove the blacklist. If you install manually, you will have to set up your own blacklist.
For most information, research rtw88.

Thank you as well, unfortunately the built-in one was not working. I tried using that one first, was detecting the network, but was not able to connect to it. Was a strange issue.

I've been testing the in-kernel 8812bu driver and it is working well here. I guess I need to test the in-kernel driver for this chipset.
What is the vid/pid for your adapter?

Sure thing, here is the full output of the lsusb for the wifi dongle.

I've confirmed that the 8821cu rtw88 driver is not working. I tested kernels 6.2 - 6.5. It may be that Sasha does not have a 8811cu adapter to test. I will contact him and see what he wants us to do as far as when he can work on it and what he needs from us testers. Are you available to help?

I emailed the developer and maintainer of the usb support for rtw88. I explained the situation and offered help to get it fixed. I hope to hear something back soon.

Sure, my work PC is on kernel 6 so I could just uninstall the github driver and test it. If I recall right, the uninstallation reverts back to the built-in driver, no ?

If you are using the driver in this repo and you use the below to remove the driver:
sudo sh remove-driver.sh
The in-kernel driver was included starting with kernel 6.2 so anything older won't work.
There is no need to do anything right now as I have confirmed the in-kernel 8821cu driver is dead.
I'll let you know.
