    Here is my problem.

    I have been assinged a static IP address from work.


    I goto basic and set it to static and key in this information. I have my pc plugged into the switch portion with dhcp enabled. I have the cable connection plugged into the wan port.

    The internal lan ip is, my computer pulled

    I can ping, I can ping the wan but I cannot get on the internet.

    If I take the same IP address and set them on the NIC in my laptop and plug the WAN cable directly into my system, it works great.

    The weird thing is I look in the routing table and there is a reference in there of WAN. Where did it pick up this .208 address? I believe this could be my problem. I have updated to the latest firmware. I've reset the dang thing.

    Does anyone know what could possibly be happening?

    There's a lot of things that could be the problem, but my very first guess is "did you reset the cable modem after you plugged in the router?"

    Cable modems are notorious for remembering MAC network addresses. In order to put something new on a cable modem, it's almost always necessary to reboot the modem as well.

    Also, go to a command line and run "tracert". This will show the route your packets are taking across the internet to get to Yahoo.

    Post a "tracert" with the router plugged in, and not. You can mask your IP in the post if you want, mainly I would want to see the IP's after your initial IP.

    208 is your network ID. It is ok. As far as the mac address situation, the easiest way to deal with that is to use the clone mac address feature on the router. Maybe give the gateway a ping too.

    In addition to what's been mentioned, just make sure your router is to "DHCP" so it will automatically obtain the ip address your isp has assigned to you.
