How can I get this wrt54g to act as a wired AP w/wireless

    I have the v1 hardware of the WRT54G.

    What i have is a ms700 wireless router as my gateway for the internet. from one of the LAN ports of the MS700 to the "internet" port on the back of the WRT54G there is a 75' patch cable running from one end of my house to the other. I was told to disable the dhcp on the WRT54G and under the advanced routing tab to change it to router with dynamic routing "both" enabled.
    I didn't have any luck with that and the two routers didn't seem to talk.
    I've changed the firmware to the dd wrt v22 r2.

    I still can't figure this out. My goal is to get the laptop and the computer on the WRT54G side to be able to use the internet and the network printer. the printer should be accessable by all computers. I just can't seem to get this to happen. is this drawing possible?

    Patch your 75' patch cable from WRT54G WAN port to one of its LAN ports. Then you have a flat network, your WRT54G acts a switch and does no routing at all.

    Your clients in WRT54G get IP addresses via dhcp on your mn-700 and should have access to all devices in your local ip network.

    will the wireless part of it still work? any other settings besides disabling dhcp need to be set?

    oh. on the computers. i set them up for static IPs. Do i have them point to the MN-700 IP address for the gateway and stuff or to the IP for the WRT54G?

    the pc connected to the WRT54G with the cable can get on the internet and access the other router. but it can't access the WRT54G, even though it goes through it. when i connect wirelessly to the WRT54G, i can access its web app, but not anything else.
    i need to be able to connect wirelessly to the WRT54G , and access the printer connected to the WRT54G and to the internet. is this possible?

    This would be the correct set-up for your WRT54G, msn700 to lan port of the WRT54G, disable the dhcp of the WRT54G, change the oprating mode "router" you can find this setting in the advance routing tab then you need to change the device IP or LAN IP of the router, the IP that you need to use it should be on the same subnet of you msn router. E.G.: if the msn700 IP is the IP of the linksys should be or one of the pubelic IP that came in the msn700.

    For that kind of set-up WRT54G will be part of the network of the msn700, and the IP that receive by the wireless laptop and the network printer is came from the DHCP of the msn700 router.

    network set-up: msn700 ---lan to lan--- WRT54G ))) wireless laptop

    sorry it should be private IP not the public, my mistake....

    hmm, that is the way it is. the laptop does connect to the linksys, but not through it.to the internet or to any of the other computers on the LAN side of the WRT54G. is there some other setting? shouldn't the WLAN and the LAN be bridged when its in AP mode?

    Yes, WLAN and LAN ports are bridged in AP mode, except you played around with vlan settings.

    Your settings on WRT54G:

    WAN: disabled
    LAN: static IP in your subnet
    Gateway: Inside IP of MN700

    DHCP: disabled
    Mode: Router (in fact, it does not matter when not using WAN port)

    The IP for your WRT54G ist just needed for administration. It does neither assign IPs via DHCP nor act as gateway for clients connected to it.

    With this setup it _must_ work, since it works as managed switch and has no influence on traversing packets. Firewall won't have any influence, either.

    WAN disabled where? in advanced routing under dynamic routing? so it should only be LAN and wireless?
    or uncheck it under VLAN settings so only the ports 1-4 are bridged and WAN isn't?

    There is no option to disable the WAN port. Just connect a cable from Lan 4 on WRT to other router.

    main router
    second router
    disable DHCP

    I have a very similar setup to yours with the exception that my primary router is a Linksys BEFSR81 (8pt router). Here is how I have mine setup and working. I use a mix of DHCP and static addresses.

    Static addresses:
    BEFSR81 =
    WRT54G =
    DLink 54G Gaming Adapter (modified MS-740) =
    XBox =
    HP LJ 5N =
    File Server =

    DHCP Scope

    Changes made to the WRT54G (out of the box) using a PC via wired connection (note, this was done completely off my standard network):
    -Changed the local IP address to
    -Disabled DHCP Server

    Physical Setup:
    -Cable modem to BEFSR81 on its WAN port
    -Standard port from BEFSR81 to a standard port on the WRT54G (just don't use the uplink or WAN ports on the WRT54G)
    -HP LJ 5N to standard port on BEFSR81
    -File Server to standard port on BEFSR81
    -XBox to standard port on WRT54G

    What this gives me....
    ...access to the printer from either the wired or wireless devices
    ...access to the internet from wired or wireless devices
    ...ability to modify settings on either of the routers from wired or wireless devices
    ...ability to access my file server from wired or wireless devices

    Since you are using static addresses on your devices connecting to your network through the WRT54G, as is my XBox. You will need to set the gateway of those devices to point to your primary router ( and also populate the DNS server entries as supplied by your ISP.

    Hope this helps iron out the details of this type of setup.

    I've just gave up and switched the routers. made the WRT54G the main router, and put the mn-700 into ap mode. now it all works. that is all it took. I just couldn't figure out what i needed to do to get the damn WRT54G working as the second router. I tried everything. oh well. thanks for all your help guys.
