    ok.. a WRT54G, by itself, doesn't have an adsl "modem" or anything like that.

    So you must have another box of some sort, as well as the WRT54g? (Or, you actually have ethernet-drop to your house..?)

    Either way..
    pick an interface - IE FE0/1
    Plug the cable that's currently connected into the WAN port on the WRT54G into this port
    then configure this port with the appropriate settings - I suspect it may be DHCP, but not certain.
    Please do show your appreciation to those who assist you by leaving Rep Point
