Network Your Computers

It may sound really difficult, but creating a local area network (LAN) is a simple and convenient way of linking two or more computers together in your home or small office. There are many benefits to having a LAN. With your network, you can share a broadband Internet connection, exchange files, and share a single printer between multiple computers.

Networking equipment

The first tool you will need to build your LAN is a router. However, before you invest iAn any equipment, decide in advance whether you want a wireless or wired LAN. Overall, a wireless network is easier to install, but there is the risk that unauthorized users may intercept your wireless transmissions or gain access to your files. A wired network requires that you run Ethernet cable through the attic or walls of your home or office. However, it offers greater security.

Both wireless and wired LANs require an Ethernet network interface card (NIC) to be installed on the primary computer. The primary computer should be the one thats connected to the Internet with cables. You must install a wireless access point on each of the other computers on your wireless LAN. However, to connect your wired Ethernet network, you must run a line of Ethernet cable from your router to the NIC on each computer youd like to add. This can be difficult if you have computers throughout your house.

Sharing an internet connection

If you have a broadband Internet connection, you can share it among multiple computers. The following steps are very common, but youll want to make sure to follow your manufacturers instructions:

Disconnect your broadband modem from the Ethernet NIC on your primary computer and turn it off.
Ensure that your router is disconnected from the power.
Attach one of the Ethernet ports from your network router to the computers Ethernet card.
Then connect the "Internet" port to the port on your DSL modem.
Power on your modem and wait two minutes.
Reconnect your router to the power source and test your Internet connection. You may need to program your modem and router with your Internet log-in information to get them working properly.
Once your equipment is properly installed and your Internet connection is active, turn on all your computers, modems and printers to continue with software setup.
