Setting Up a Home Network

Even though they're easy and flexible, wireless networks aren't for everyone. Some people simply feel more secure when using a wired network, and others want to move lots of data very quickly. In either case, a wired Ethernet network is the better choice. Ethernet networks are faster than wireless networks, and they can be very affordable. However, the cost of Ethernet cable adds up -- the more computers on your network and the farther apart they are, the more expensive your network will be. In addition, unless you're building a new house and installing Ethernet cables in the walls, you'll be able to see the cables running from place to place around your home.
If you plan to connect only two computers, all you'll need is a network interface card (NIC) in each computer and a cable to run between them. The most commonly used cable is Category 5 Unshielded Twisted Pair (UTP) cable. If you want to connect several computers or other devices, you'll need an additional piece of equipment -- an Ethernet router. You'll also need a cable to connect each computer or device to the router.
Once you have all of your equipment, all you need to do is install it and configure your computers so they can talk to one another. Exactly what you need to do depends on the type of network and your existing hardware. For example, if you choose an Ethernet network and your computers came with network cards already installed, all you'll need to do is buy a router and cables and configure your computers to use them. Regardless of which type you select, the routers, adapters and other hardware you buy should come with complete setup instructions.
The steps you'll need to take to configure your computers will also vary based on your hardware and your operating system. These links include more detail on how to get your computers talking to one another:

If neither wireless nor Ethernet seems right for you, you have other options for connecting your computers. If your computers have USB or FireWire ports, you can use cables, jump drives or file transfer devices to move files from place to place. Other options include power-line and phone-line networks. Both power- and phone-line networks use existing wiring in your home to connect your computers, so you don't need to worry about concealing extra cable.
