Is the router set up to be a DHCP server and to give out IP addresses? Is there a built-in firewall? Does your PC successfully get an IP address when connected to the router?

CSCGAL,

Thanks for the response.

Yes the router is configured for dhcp, yes it does give me an ip address, to my knowledge there's no built in firewall.

Most modems only remember one MAC address until it is rebooted. Many times people will plug in their PC (Modem learns PC MAC address) it works, plug in router, and it doesn't work. Try this:

connect up pc to router, connect router to modem
Power off router
power off modem
power on modem
power on router

See if that helps you.
