Can this be done with access point?

    Hi everybody, I'm not sure what technically what I'm trying to do, so I'm going to describe the set up I'm trying to achieve. I have two wrt54 routers with tomato firmware.

    1. The main one is in my basement attached to my cable modem and acts as an access point with wpa secured wifi. It also provisions four Ethernet ports in my house upstairs.
    2. I want to add a second wrt54 upstairs for better wifi coverage. I want to connect it via Ethernet to the main router. I know about using the non-overlapping channels, same ssid and encryption for the wifi. What I want to also do is connect a computer in the same room via Ethernet. Instead of buying a switch to share the connection between the wrt54 and computer, I'd like to be able to plug the computer into the wrt54 access point. I would like the computer to be on the same subnet as the home network to allow network discovery, file sharing/network drive mounts, and upnp to work.

    How would I configure the upstairs, secondary wrt54 to act as a wifi access point and also essentially act as a Fast Ethernet switch for the wired computer? If tomato can't do this, I'm not averse to flashing to something else.

    Thanks for any advice.

    Connect your two routers together, LAN port to LAN port.

    To be a bit clearer than bigclaw's short and to the point message...

    1) Your WRT is always a 4-port fast ethernet switch, just like any other ethernet switch - the LAN ports.
    2) If you set Tomato to "AP" mode, your WRT is ALSO a wireless Access Point.
    3) If you connect something to the WAN port, your WRT is ALSO a firewalling NATting router.

    Your WRT is also a computer, so you can have the WRT do many more things, depending on which mode you put it in, i.e. what pieces of the software (the firmware - Tomato) you run on it.

    For your purposes you'd like, on your 2nd WRT, (1) and (2) above, so treat it like any fast ethernet switch, and then configure the wireless stuff in addition to that.

    I have almost the same setup, With one router (a Belkin running their firmware) providing NAT to the 'net, and a Tomato box elsewhere for some machines with weaker antennas. (I know, I'd prefer the Tomato as NAT, but the modem won't get along with it.) I have a wire going LAN to LAN, and it works very well. I have both routers nearly plugged full, I only left the "extension" router's WAN port empty.

    I never had success with sharing SSID's, though. I just gave the two routers similar SSIDs, the same password, and configured each computer twice.
