Wireless Repeater + Wired switch?

    Let me begin by apologizing for my ignorance...it has been a long time since I've gotten deeply involved with networking, and I'm afraid I don't know the correct terminology to effectively search for the information I need to do what I'm trying to do.

    I currently have two WRT54G's running tomato 1.27. One is connected to the WAN/Modem and has several wired devices, located in my office. The other is located in the living room and is connected via WDS and currently has one wired device connected.

    My issue is that due to the distance between the two routers the speed is low. I would like to replace the wireless link between the two with a wired link, yet still maintain the ability for wireless devices to connect to the secondary (living room) router if the signal from it is stronger than the primary. I will eventually like to duplicate this connection to a third router in my bedroom.

    In essence, I believe I want the secondary router to act as a switch, and a wireless AP, routing connections via the wired link to the primary router. Is there any special configuration required for this? Do I need to disable WDS and simply run a line from a LAN port on the primary to the WAN port secondary?

    No. Connect a LAN port on the primary to a LAN port on the secondary. Disable the WAN port and DHCP on the secondary. Set the LAN address of the secondary to be part of the network specified by the primary LAN, but outside of its DHCP range. A common value would be Set the manual DNS values and gateway value to be the primary's LAN address, typically Set the wireless SSID and security settings the same on both devices, but set the channels to be different values (sufficiently spaced to not interfere with each other, such as 1,6,11). Set the wireless mode on both to be AP only.

    This setting will allow a client to roam between the two AP's, selecting the one that has the best signal while making sure the two wireless "networks" don't interfere with each other. It will produce one logical network with DHCP and DNS service provided by the primary. The secondary is acting as a switch with an access point attached.
