Also, AT&T mentioned something about paying an extra $9.95 a month to hook up another computer. I'm assuming that if I provide my own equipment, I can share the one cable connection I am paying for like I did with the dial-up ISP.
1. Get a second NIC for the computer that cable modem is plugged into and run my existing hub off that. Configure the network as before but share the internet connection on the other NIC (which means the computer with the cable modem must be on all the time.
2. Install a DSL/Cable router. Connect the cable modem to that and "clone" the MAC address from my NIC to the router. Connect my two PCs to two of the ports on the router. This way I have a firewall and scalability with my network. I am leaning in this direction.
Somebody told me at work today that with the router, I cannot hook the PCs directly into it. That I must plug my PC's into my existing hub and then plug the hub into the router. Is that correct? If I get the router, it will be the Linksys router that Steve W. linked to in reply #3.
