    Maybe someone has been through this before, I can not get the unit to pull down an IP address from comcast unless I deactivate NAT and Routing under the advaced tab under administration, once I deactivate it I can get the IP fine and I can get to the internet. I am on my second WCG200 because Linksys tech support said my first one was broken, but the new one has the same issue, so I am thinking it must be in the setup of the unit. If anyone could help I would appreciate it. Thanks :( :(

    is there a "block Wan Requests" feature? disable that if there is and try again. the UBR may need to ping you and block Wan Requests makes you unpingable.

    just a thought

    When you deactivate NAT and Routing does this box just turn into a plain cable modem? If so, which if any of the ethernet ports are still active?

    did you ever figure this out?
    i have the exact same problem, out of the blue today.

    service here was upgraded and now my account has a new semi-static ip. i say semi-static as technically it's dynamic, but my ip never seems to change. Now if i turn off NAT and Routing everythng is fine...i get online.
    but when i have NAT and Routing on, the wan ip is reported as my old ip and renewing the wan dhcp etc has no effect..always the wrong(old)ip.

    i've tried resetting it and factory restore etc...no luck.

    i entered all the info in as a static ip and it works fine too, but it will be a pain to update the info manually every time i get a new ip assigned to me.

    I was hoping you had found a solution.

    Unfortunately no. Never did recieve any replies and never did try it.

    I am having the exact same problem with the WCG200 on RCN. I can disable NAT/Routing and get an IP address but then I lose the routing functionality. Has anyone found out how to get this resolved?

    the issue may be MAC-ID filtering on your ISP's side. Try using mac address cloning.

    Thanks for your reply. So RCN can tell when my WCG200 is also being used as a router, even though I still have the same MAC address registered with them? If I change it to something different, this won't happen?
