Your device should be based on "RTL8822B" chip from Realtek, so you need to install "firmware-realtek" package.I thought this would be easier than it's turned out to be. There are Internet posts going back years about support for this device but nothing recent - including a 5 year old Ubuntu post saying it works. Other wifi devices seem to be recognized out of the box or with a simple install of non-free firmware but not this one - at least not in Bullseye or Bookworm.
The adapter itself seems to be quite popular so I'm hoping someone can provide some clues on how to make it work
Thanks.
