Each of my AP's are RB411a's with a r52 wireless card, and the lan and the wlan are bridged together. Assign it a particular ip in your choice of range....I like 10.5.50.x. Make sure that your WLAN is in AP/Bridge mode.
My main router is a rb493.....each of the AP's are directly connected to it. Create a hotspot on a bridge port consisting of all of the ports that the AP's are connecting to. In the hotspot settings, make sure that each of your AP's are bound in the IP Binding tab, and VOILA
