    Problem: can not get wired LAN internet access with Linksys WRT54G router
    configured as DHCP router (necessary for wireless laptop connectivity). BTW,
    static IPs will not work as all three laptops extensively travel and use WiFi
    hotspots.
    Current configuration: 4 servers (all Dell; one is gateway for LAN), 20
    desktops, and 3 wireless laptops (one is the owner's); all computers connect
    via hub; all use TCP/IP with dynamic IP except for the servers (all fixed
    IPs). Configuration looks like this: ISP -> cable modem -> Gateway server ->
    hub -> all other computers.
    Desired configuration: ISP -> cable modem -> WRT54G -> Gateway Server -> hub
    -> all other computers; laptops would connect via WRT54G. Linksys Tech
    Suppport suggestion: make all wired computers have static IPs and desired
    configuration will work (who wants to configure 25+ NICs?); otherwise, static
    IPs for laptops and disable DHCP on router. One other suggestion was to put
    the router between the Gateway Server and the hub.
    Any assistance will be greatly appreciated. :(

  2. Need more info about what you are trying to do - just give wireless access
    to the network/Internet to laptop clients?.

    Why not get rid of the gateway server altogether ISP -> cable modem ->
    WRT54G -> hub -?

    What does the Gateway server do for you that the WRT54G does not - running
    ISA or some other sophisticated firewall?

    Is there a reason for separtating the laptops from the rest of the network?

  3. It would help if I new why you wanted to use a wireless "router". If all
    you want to do is add the ability to have wireless machines on the
    LAN,...all you want is a Wireless Access Point (WAP),..not a "router". It
    would connect to the Hub just like the rest of the other machines.

    ISP -> cable modem -> Gateway server -> hub -> all other computers *and*
    WAP.

    The Gateway Server should be the one doing the NAT and the DHCP. The WAP
    would get its IP from the Gateway Server the same as the other
    machines,...however it would work perfectly fine without an IP (it doesn't
    need one),...the IP is only used if you want to get into the HTML-based
    Management features on the thing that most of those have. Without an IP you
    can still get to it using he software that comes with it on CD that runs
    right off the CD (no need to install anything) and communicates with it
    directly by Layer2 addressing (MAC Address),...at least that is the way the
    Linksys one do it. The WAPs are really nothing more than a "wireless
    hub",...that is all they do.

  4. The WAP I have sitting right next to me, unused, still in the box, is a
    WAP54G. Notice the similarity in the model to your "router". It is
    basically the same device as your except that it is only a WAP and not a
    "router" as yours is. Actually your WRT54G is really a NAT Device, and DHCP
    Server, and a WAP all built into one unit,...it is not a "real" router. But
    you have 2 features too many,...all you need is the WAP,...which is what the
    WAP54G is.
