    Hi! I have a strange problem with my WRT54G router. here is my configuration:

    internet - router - WRT54G (firmware 1.42.2)

    the router is connected in 1 of the 4 ports of the WRT54G. i disabled the dhcp server in the WRT54G, but when i try to connect with a windows box i just receive an invalid ip address. the dhcp on the router is configured fine because with my mac box i receive the correct ip and gateway. i tried disabling the wep, changing the advanced routing (gw and rout) and many resets. i'm sure the router is configured correctly because it was working before the reset. Anyone had the same problem solved? its like the dhcp server on the router doesn't work with the win boxes!
    thanks in advance and sorry for my english

    1) Are you successfully connecting to the Wireless LAN?

    2) If so, try setting the windows PC to a static IP address, like and then see if you can ping the router (

    Report back here the results.

    If you use static IP Address, make certain that the DNS IP Addresses are entered in the TCP/IP seting of your NIC and the gateway address is with a subnet mask 0f The LAN port of the second WRT54G must be connected to one of the LAN ports of the Gateway router.

    Actually the DNS and Gateway entries are un-necessary for simply trying to ping the router...

    On your PC box, from a cmd (DOSwindow), type 'ipconfig'. This should display:
    IP Address
    GW Address
    What does this show?

    I don't know much about how to look at the same information on the Mac box, but if you can retrieve the IP address and GW address, that would help trouble-shoot your issue.

    It appears to be an issue on the PC box rather than in your router or WRT54G device. If you can provide the above, hopefully somebody or myself can quickly help you.
