I needed a Linux desktop with Wi-Fi capabilities for a project I was working on, flashing valetudo to a dreame x40. The only problem is that my extra computer that I could install the specified Linux flavor on, was a mini PC with no onboard Wi-Fi. So I did some research and found this adapter that has good Linux support:
For Debian, the driver install is a single quick install away.
sudo apt install firmware-mediatek
The adapter ended up working out great and I was able to finish up the valetudo setup with it.
