We support wireless adaptors which are on boards, we just don't support 3rd party hardware. That is mission impossible. With exception of OrangePi Zero / Nanopi Duo, which has some bad wifi chip, all works fine.
You need to look for some "Linux compatibility lists" and/or buy what is supported. Rpi is popular but that doesn't mean it has an advantage in this area. I have a lot of wireless adaptors for testings and to try to make them work ... Some work fine on Linux, some don't.
