This repo ONLY supports adapters with the 8812au chipset (AC1200). Period.

You should check in the file supported-device-IDs here before installing this driver unless you are sure your adapter uses a 8812au chipset. If you do not see your device ID in supported-device-IDs then check the same file in the following repo:

https://github.com/morrownr/8821au-20210708

The above repo supports the 8811au and 8821au chipsets (AC600).

I realize this can be somewhat confusing and I do my best to help but the confusion was caused by Realtek. Realtek has unnecessarily released a lot of different USB WiFi chipsets that all require different drivers. Realtek has a long history of doing this type of thing. It is just one more thing that makes using Realtek based adapters a challenge... which is why I recommend buying adapters with Mediatek chipsets:
