If you are just connecting the devices locally and no internet access is needed you can get a dumb switch such as http://www.amazon.com/NETGEAR-ProSafe-Gigabit-Ethernet-Desktop/dp/B00006RVPW

If you are using just the switch Windows will auto assign ips, Macs need a bit more setup, but repost if they are also involved.

If you need internet access then you would need a router such as http://www.amazon.com/Netgear-WGR614-Wireless-G-Router/dp/B00008SCFL/ref=sr_1_1?ie=UTF8&qid=1321369691&sr=8-1

These are just two options as the first things that came up from google, but there are many many more options that would work.
