ok i think we made some head way.
we managed to get wireless adapter detected in virtual switch by removing wireless ap station, restart qnap, reinstall wireless ap station.... re-add wireless access point.
it then creates a virtual switch for the wireless ap, and it successfully becomes active.
not sure why it bugged out like that before, but remember that container station is a dependency for wireless ap station. so maybe not a good idea to remove or disable container station, because wireless apstation requires it to function. i suspect that could be one possible cause.
i noticed that the virtual switch created bundled your adapter1 with your wireless adapter. I'm not sure if that is ideal or not.
For me, i separated adapter1 and wireless adapter. meaning i had 1virtual switch solely for adapter1, and another switch created solely for the wireless adapter.
I think the reason i did that, was because i may have had issues with the initial setup. Maybe someone can explain about this better than i
