Wireless Local Area Network
A 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
• A network cable with a network (RJ-45) connector
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
