Setting Up and Using Networks

Setting up a computer network provides connectivity between your computer and the Internet, another computer, or a network. For example, with a network set up in a home or small office you can print to a shared printer, access drives and files on another computer, browse other networks, or access the Internet. You can set up a local area network (LAN) using a network or broadband modem cable or set up a wireless LAN (WLAN).

The Microsoft Windows

®

XP and Microsoft Windows Vista™ operating systems provide wizards to help guide you through the process of networking computers. For more information about Networking, see the Windows Help

and Support Center (see "Windows Help and Support" on page 19).

Connecting a Network or Broadband Modem

Cable

Before you connect your computer to a network, the computer must have a network adapter installed and a network cable connected to it.

1 Connect the network cable to the network adapter connector on the back of your computer.

NOTE:

Insert the cable connector until it clicks into place, and then gently pull on the cable to ensure that it is securely attached.

2 Connect the other end of the network cable to a network connection device or a network wall connector.

NOTE:

Do not use a network cable with a telephone wall connector.

Wireless Local Area Network

A wireless local area network (WLAN) is a series of interconnected computers that communicate with each other over the air waves rather than through a network cable connected to each computer. In a WLAN, a radio communications device called an access point or wireless router connects network computers and provides Internet, or network access. The access point or wireless router and the wireless network card in the computer communicate by broadcasting data from their antennas over the air waves.

What You Need to Establish a WLAN Connection

Before you can set up a WLAN, you need:

• High-speed (broadband) Internet access (such as cable or DSL)

• A broadband modem that is connected and working

• A wireless router or access point

• A wireless network card for each computer that you want to connect to your WLAN

Checking Your Wireless Network Card

Depending on what you selected when you purchased your computer, the computer has a variety of configurations. To confirm that your computer has a wireless network card and to determine the type of card, use one of the following:

• The Start button and the Connect To option

• The order confirmation for your computer
