    howdy - would it be possible to plug a WRT54GS into my extensively wired Ethernet local area network to allow wireless clients to connect to the WRT54GS ~AND~ be able to use the LAN resources for file sharing & internet browsing?

    My WRT54GS currently has Thibor 13d firmware.

    what settings do I need? should i use a crossover cable?

    Do I need to keep the WRT54GS on its own subnet or can I join it to my LAN? My LAN has two of it's own DHCP servers, so I wouldn't want the WRT54GS to interfere with things on the Ethernet network.

    Thanks, in advance, for any help you may give; I know I asked a lot of questions.

    if you want to bridge the wireless and wired networks (both use the same ip address space) then just disable dhcp on the wrt and plug one of its lan ports into a switch port on your lan. the clients will get a dhcp ip address from your existing dhcp server(s) and join the same network.
    youll also want to make sure that the ip address of the wrt is set to something that wont conflict with an existing host on your network as well though.

    thanx, xrat; should i plug it into my LAN's switches with a crossover cable, or not? i'm confused when a crossover cable should & shouldn't be used.

    should set the WRT54GS to be an access point or a WET or WDS or what?

    Do not use a crossover cable, use a regular Ethernet cable. If you are using stock Linksys firmware you really do not have a choice. You are using the WRT54G as an access point. You have to disable the DHCP server on the WRT54G. If the local address of the router you are using as a internet gateway is, you will have to change the local address of the WRT54G to an address on the same subnet as your main router, but outside the range of the IP Addresses the DHCP server on that router is issuing addresses. In Advanced Routing change the set from Gateway to Router.
