Gunner, lets try the Netgear forums and see what we can find
http://kbserver.netgear.com/main.aspI really think it has to with the MAC cloning Gunner. Try these steps exactly. Assuming that the MAC address has been cloned properly (Cloning your desktop ethernet's MAC address to the routers) With everything running, cable modem, router and your computer.... Reboot the cable modem then the router and lastly your computer. Do this in this order making sure each has fully booted before booting the next appliance. Let me know.
What this will do is push the cloned mac address through the router to your ISP (Charter). You should never have to do that again unless you shut down the router. Even then, I don't think you will have to do it then.
