I actually use WDS.  Each satellite router connects to the gateway
router wirelessly.  There is one SSID in the system and one DHCP server.
The satellite routers serve as wireless repeaters and offer wired
connections with system DHCP via their switch ports. The WDS
functionality is apparently an undocumented feature of the Linksys WRT
routers.  It is much better documented in OpenWRT.

The more simple case is to use the router as a client to connect to the
existing system wifi network.  Then you can adjust the switch
configuration so the LAN ports on the device serve system DHCP.

Clear as mud?  Maybe Rob should bring in a router for a 20 minute
demo...
