What WIFI adapters are compatible?

I have already visited the wiki but in the forums but in answers of the forum there are Wifi adapters not listed. How do you determine if Wifi adapter is valid or not?

Anything with an rtl8812au chip, an ar9271, or most Ralink chips will work.

If you can find and afford them, the Asus AC-56 cards are highly recommended, but there are others.

There are a few that would technically work but are either not compatible with a raspberry pi or which don’t quite work properly for one reason or another.

You may find cards that say they are rtl8812au chip inside but that are really rtl8812bu or similar, those are not worth the trouble at the moment.
