I'm on Monterrey. I recently found a need to get High Gain Wifi for my Mac and after some research, I found there are no wifi adapters after 10.15. MacOS 11 & MacOS 12 are not supported officially. I read the wifi manufacturers are waiting on the chip manufacturers and there's no response from the chip manufacturers. I can't guess as to why. Perhaps MacOS changes make it difficult?
in any case, I did find a work around using a Wifi range extender like the Linksys AC1200 Max (RE6500HG <- high gain version). it connects to the source and provides a local hotspot for it that the mac can connect.
