Have you tried testing the adapter on every available USB port on the computer?

Another thing to try is to use another computer to see if the issue followed the adapter or stays with the computer.

@Tony yeah I've plugged it into every other USB plug on my PC, now I constantly get a notification saying it would preform better in a USB 3 port but I still get it when its plugged into a USB 3 port.

You could try the previous driver available on our website, and also you could try the chipset manufacturer drivers here:  https://www.realtek.com/en/component/zoo/category/rtl8811au-software

They do ask for an email before downloading the file.
