I purchased the same WiFi receiver (Archer T2U Plus) yesterday. I'm running bootcamp on my MacBook for work, and it worked fine on Windows 10. However at the end of my shift I tried to install the driver for Mac OS 11.2, and to my surprise it didn't work. Going on the support forum from Tp-Link I realised the company doesn't care about the lack of functionality, as far to advise customer to re-install previous OS versions or to go against Apple recommendations by disabling the SIP and give the authority of their App on your macOS. (quote from the forum) Fortunately enough I was able to return the item and get a full refund, and I would suggest the same for everyone that's able and just look for an actually functioning alternative.
