Steve,

Thanks again.

However, my router is configured correctly. I have the cable modem
connected to the Internet port and the 3 PC cables connected to slots one two
and three.

The device is a Linksys Broadband Firewall Router with 4-Port switch and VPN
Endpoint. It is model BEFSX41.

I am not paying more money for a second IP address, so that is not a concern.

I've removed the MAC bridge from the downstairs PC, but since that can't
connect it hasn't made much of a difference.

Thanks for sticking with me here.

Take care.

Greg
