Unleashed R500 shows disconnected status with remove button (i.e., no approve button). I have another thread where I posted my two R500s are both masters and neither one joins another. After executing "set director ip x.x.x.x" on either AP it will allow it to be added as #2 but shows up as "disconnected" status. See screenshots.
Sorry if this is double post. But it is a different issue and probably deserves a new thread.
