Help: How to use USB ADSL via ICS thru WRT54G

    Hello. My ISP only provides DSL through a USB connection. But I want to share that connection wirelessly thru the WRT54G to my notebook computer equipped with the WPC54G.

    Initially, I was able to connect the notebook and the direct connection PC without difficulty but I had it configured to receive DSL thru the WAN port, something I cannot do with my modem. But I want my direct connection PC to provide Internet to any other computers on the network through ICS via the WRT54G.

    When I tried to configure it that way using the network wizard to choose "this pc connects direct; provides internet to others", the direct connection PC no longer spoke (via to the router and falls off the network; the notebook stays on just fine and can talk to the WRT54G.

    How can I configure the router such that it allows me to receive my DSL via USB through one direct connection PC and then distribute it via ICS thru the WRT54G wirelessly to my notebook and renew the connection between the two PCs and the direct connect PC and the WRT54G. I've seen the Advanced Routing mode but I do not know how to configure it. I've tried :oops:.

    Thanks so much for any help on this! 8O

    Try the following

    1. Turn of local DHCP server on the router, your ICS computer will hand out IPs.
    2. Connect your ICS computer to one of the LAN ports on the router.
    3. Configure ICS to share the connection as you did before.

    The WAN port will go unused on the router. When using ICS you are esentialy turning your PC into a router, and ICS provides its own DHCP server.

    Fantastic ... but

    That worked like a charm. I'm in business. :D

    But I have one question: Now that I've cut off DHCP, I'm no longer able to talk to the router. I'd like to be able to if I wish to tweak any wireless settings.

    Previously, after initiating ICS, the direct connect PC lost contact with the router. But the wireless notebook did not. Now, after turning off DHCP, the notebook can't reach it either.

    So: How can I talk to the router in this setup? Is it possible?

    Thanks so much for your help, simple but tremendously effective!!

    I forgot that there might be an IP address conflict.

    What ip address range does ICS give out?

    Your router will still have the same IP it had before. The default is

    If ICS is giving out IPs in a different range your computer will not see the router.. If they are in the same range, chances are the ICS computer will give it self so it conflict with the router.

    Simply disconnect the ICS computer from the router and connect a computer to one of the routers WAN ports and set a static IP of . You should then be able to access the web config. If ICS was giving out IPs in a different range, change the routers LAN/local IP to match that range, if ICS was giving out 192.168.1.X IPs then change the routers IP to something other than, preferably something like this way its is unlikely that ICS will give out that IP and have another conflict.
