Chapter 3: Networking

Setting up a wireless network

This section describes the steps necessary to set up a typical home or small office wireless network, which is also called a wireless local area network (WLAN), using a wireless computer.

To set up a wireless network and to connect to the Internet, you need the following equipment:

■A broadband modem (either DSL or cable) and high-speed Internet service purchased from an Internet service provider (ISP)

■A wireless router (purchased separately)

■Your new wireless computer

The illustration shows an example of a completed wireless network installation that is connected to the Internet and to a wired computer. As this network grows, additional wireless and wired computers can be connected to the network to access the Internet.

Step 1: Purchase high-speed Internet service

If you already have high-speed Internet service (DSL, cable, or satellite), begin with the “Step 2: Purchase and install a wireless router” section. If you do not have high-speed Internet service, follow these steps:

1.Contact a local ISP to purchase high-speed Internet service and a DSL or cable modem. The ISP will help set up the modem, install a network cable to connect your wireless computer to the modem, and test the Internet service.

2.Your ISP will give you a user ID and password to access the Internet. Record this information and store it in a safe place.
