The documentation for your router should tell you the maximum number of clients, but it's usually 256. Because of bandwidth restrictions commerical wireless outfits try to limit it to <20 clients per WAP. Unless several of your users d/l MP3s and porn all day you should be OK with 12 clients.
So yeah my statement would be correct depending on your hardware interface on the Access Point.
