If you want to connect more than one computer to the internet in your house or apartment, you'll need a couple of things:
Unless all of your computers are in one room, we highly recommend you purchase a wireless access point or a wireless router/hub. These devices allow you to connect all your computers without using wires (thus wireless!). We do not recommend you run wires all over the place and punching holes in walls is likely to cause you considerable problems for your damage deposit!
That said, for a typical house with, say, 3 roommates each with a computer, you will need:
This sounds like a lot, but in reality you can purchase one device that combines the functionality of (3),(4), and (5). These are wireless routers that include hubs. Examples include products from Netgear, Linksys, and 3Com, among many others (link to them). You can get such devices at Office Depot, Staples, Circuit City, or any other electronics store and they are generally under $100.00. Most of these also include what's called a "firewall." A firewall helps protect your network from hackers and other intrusions from the internet.
So what you really need, unless you know you don't have need for one or more pieces, is an internet connection (which will generally provide the modem as well), a wireless router/hub, and a wireless card for all computers.
Please note that there are several types of wireless devices and all of the devices you purchase must support the same protocol, basically that they all speak the same language. The key is that your router/hub support any protocols that your cards have. So if the hub supports 501a & b and a card supports only the newer g protocol, then things won't work.
You'll hook the internet connection (a cable cable (called RG6) or a telephone cable) into your modem. The modem will have a network cord to connect to the Router. The router then connects to machines via wireless connections (thus why you need the cards) or wired connections (cat5e cables).
You'll need to follow the instructions for the devices you purchase since they all vary a bit, but in general set-up is pretty easy.
Another thing to think about is how secure your want your wireless network to be. For example, most out-of-the-box configurations have a low level of security. This means that someone in an apartment next to yours or driving by in a car could detect your network and use it for free.
We will post frequently asked questions as they arise.
