Your ISP is assigning an IP to the mac address that it first sees when you connect everything. So if you want one computer to connect directly to the modem, you would need to shut everything off, unplug the modem, hook everything together, wait like 5 minutes or so (maybe more) then plug in the modem and turn everything on. This will cause the modem to renew the IP and assign it to the computer that's plugged in. If you want to have everyone connect to the internet, you have to connect it so that the other computers gain access through the first computer. The "Set up a small or Home Office Network" Wizard in My Network Places will help you do this. It has to be run on every machine. This is because you're using a switch. If you just got a router with NAT, you could hook up the router to the modem and hook everyone else into that like you had before. Just setup NAT and DHCP and you're all set. Using a switch would require that each computer in the house has it's own IP address from the ISP, which usually costs more money per month, per IP. In the end, a router is usually cheaper and easier. Switches are great for LANs that don't connect to the internet.
