    You are probably not getting DHCP. Either manually configure your IP address or RELEASE AND RENEW your IP address.

    Goal: Make sure router is obtaining outside IP number from cable modem

    Have you tried plugging one of your computers--configured to obtain an IP address automatically--directly into your cable modem to make sure it can grab a valid IP address? (I would start out with ZoneAlarm enabled for security reasons) Take note of the ip address on this computer if all goes well.

    If you can surf when plugged directly into your cable modem, then try re-connecting your router and then access your router using your browser. Check the status of the router and see if the IP address corresponds to your ISPs address and subnet (not some number beginning with 169)

    If you see that the router has a valid IP address obtained from your cable modem, then at least that's a start.
