If you think you will be using a wireless device at any time in the future you will need to
purchase a wireless router and just disable the wireless
With a router you need to configure the wan port for it to connect to the modem and your ISP
You also need to configure the LAN side of the router for it to give each computer a difference IP address
D-Link 54Mbps Wireless Broadband Route
Or you can just use a switch for now until you need a wireless router
A switch is sometimes called an 'intelligent hub', and now that they are no longer significantly more expensive than hubs they have almost replaced them entirely.
A switch does the same as a hub, in that it connects devices to allow them to act as a single segment.
However, it does not automatically send traffic to every other port.
Each time a frame of data comes into the switch, it saves the physical address
(MAC address) and the port it came from in its MAC address table.
It then checks the destination MAC address in the table, and if it recognises it sends the frame to the appropriate port.
If it is not in the table, or the address is a broadcast address (intended for every machine on the local network), then it does the same as a hub and sends the frame through every port except the originating port.
