WRT54GS w/SBC DSL, pppoe, modem, dns server?

    i've been dealing with this issue for quite some time. i hope i'm not overcomplicating things. here is my scenario.

    SBC DSL w/Efficient SpeedStream 5100B (Modem)
    Linksys WRT54GS (v2)

    I have the modem connected to the router, to the computer and the interenet works fine. However, the wireless does not work, and I'm under the impression that the router is not connected, the internet works merely because the modem is going through (i have yet to connect another computer to it).

    The internet works when I set the modem config to standalone (not pppoe gateway -> router). But when I set the modem to pppoe, the internet does not work.

    I have set the router to pppoe w/my login and password. However when I go and try to connect, I receive a "Can not get a IP address from PPPoE server." ..

    My question now is I do not know where to set the dns servers in the linksys configuration.


    Here is my ipconfig when the modem is not set to PPPoE gateway/router (it is on the modem only configuration)

    thank you

    what does ipconfig /release & /renew do?

    btw, i have dhcp disabled if that matters any.

    what does 'domain_not_set.invalid' mean? ..and on the modem config it has an option for 'bridge' as a 3rd option. bridged mode ?

    ipconfig/release releases the the ip address of the NIC.
    ipconfig/renew re-establishes the ip address of the NIC.

    Unless you have your wireless NIC set with a static IP Address and you have specified the IP Address of your router as the gateway. From your IP Config information the Gateway address is 192.168.1.1 and the IP Address of your NIC is 192.168.1.100.

    The Siemens Speedstream 5100/5200 is a DSL modem with a DHCP server and passes DNS. It has one Ethernet port.

    You can set it in bridge mode and disable the dhcp server and have your WRT54GS handle logon the PPOE and be the DHCP server, or you can have the Siemens Speedstream 5100/5200 handle the PPOE and be the DHCP server, but then you must set the WRT54GS as a router in advanced routing and disable the DHCPserver on the WRT54GS. You should not have both the modem and the WRT54GS set as DHCP servers.
