About Your

AirPort Extreme Card

With the AirPort Extreme Card installed in your computer, you can

Access an AirPort or other wireless network at home, school, work, or Internet “hot spots,” and use it to browse the Internet, send and receive email, and more.

Set up a Computer-to-Computernetwork between two or moreAirPort-equippedcomputers, which you can use to transfer files or play multiplayer games.

Set up a computer to share its Internet connection with computers using AirPort.

Set up an AirPort network using an Apple AirPort, AirPort Extreme Base Station, or Airport Express. The Apple AirPort base stations are available from your Appleauthorized dealer or the Apple Store at store.apple.com.

Important: If you purchased an AirPort Extreme Base Station or AirPort Express at the same time as your AirPort Extreme Card, install the AirPort Extreme Card and then set up the base station using the instructions provided with it. The AirPort Setup Assistant described in this booklet is the same one used to set up the AirPort Extreme Base Station or AirPort Express. To set up the base station and configure your computer to access the AirPort network it creates, you need to use the AirPort Setup Assistant only once.

Your AirPort Extreme Card is compatible with all versions of the AirPort base station.

About AirPort

AirPort offers a simple, fast, and affordable way to provide wireless Internet access anywhere in your home, classroom, or small office. Instead of using traditional cables to create a network, AirPort uses wireless local area network (LAN) technology to provide wireless communication between computers.

How AirPort Works

In a traditional network, computers are connected through a series of wires that transfer information. With AirPort, data is transferred between computers over a wireless network using radio waves.

3

There are three ways to create a wireless network:

Use an AirPort-equippedcomputer to create a temporaryComputer-to-Computernetwork, which other AirPort computers within range can join.

Use the Internet pane of Sharing preferences to set up an AirPort-equippedcomputer with an Internet connection to share the connection with other computers using AirPort.

Create a more permanent wireless network using an AirPort base station. In this kind of network, all wireless communication goes through the base station to other computers on the network or to the Internet.

How AirPort Provides Wireless Internet Access

The following are ways that you can use AirPort to provide Internet access to AirPortequipped computers:

Connect an AirPort base station to an existing network that already has Internet access, such as in a school or small office.

Connect a cable modem or DSL modem to an AirPort base station, or if your base station has an internal modem, connect it to a telephone line. The AirPort base station establishes an Internet connection and also creates a wireless network through which multiple computers can access the Internet.

Note: To use AirPort to access the Internet, you must have an account with an Internet service provider (fees may apply). Some Internet service providers (ISPs) are not currently compatible with AirPort.

For more information on using AirPort with your Internet account, contact your ISP or go to the AppleCare Knowledge Base at kbase.info.apple.com.

Setting Up Your Computer to Use AirPort

Step 1: Do You Need to Install the AirPort Extreme Card?

If you ordered your AirPort Extreme Card with your new computer, the card is already installed. If the AirPort Extreme Card came in a separate kit, you need to install it yourself. Instructions for installing the AirPort Extreme Card are in the manual that came with your computer. You can also find them on the Apple Support website at www.apple.com/support.

4About Your AirPort Extreme Card

Warning: The AirPort Extreme Card has been designed so that you can install it yourself in some computers. If, after reading the installation instructions that came with your computer, you feel uncomfortable about installing the card, you can have anApple-authorizedservice provider install it for you. If you follow the instructions, you should not be concerned about damaging your computer. However, if you do attempt to install the AirPort Extreme Card yourself, any damage you may cause to your equipment will not be covered by the limited warranty on your computer. See anApple-authorizeddealer or service provider for additional information about this or any other warranty question. Consult the service and support information that came with your computer for instructions on how to contact anApple-authorizedservice provider or Apple for service.

Do I need to know the MAC address of my AirPort Extreme Card?

If you are going to use your computer on a large wireless network, such as in a school or office, you may need to provide the MAC (Media Access Control) address (sometimes known as the AirPort ID) of your AirPort Extreme Card to your network administrator. Your network administrator can use the MAC address to provide an extra level of security for the network. The MAC address is 12 characters printed on a label on the AirPort Extreme Card. You can also find your AirPort ID by opening Network preferences, choosing AirPort from the Show pop-upmenu, and clicking the AirPort tab.

Do I need to install an AirPort antenna?

No. The antenna used by the AirPort Extreme Card is already built into your computer.

Step 2: Set Up Your Computer to Use AirPort

If you are going to use your computer with a wireless network that is already established (such as in a school or office), do the following:

1Make sure the AirPort software is installed on your computer.

If you ordered the AirPort Extreme Card with your new computer, the AirPort software is already installed. You may not have a separate AirPort CD.

Note: To make sure that your computer has the latest version of the AirPort software installed, open System Preferences and click Software Update or check the Apple AirPort website at www.apple.com/airport.

2Choose the network you want to join from the Airport status icon in the menu bar.

If you are setting up an AirPort Extreme Base Station or an AirPort Express, you can use the AirPort Setup Assistant.

nOpen the AirPort Setup Assistant (located in Applications/Utilities) and follow the onscreen instructions.

If an error message says the AirPort Extreme Card is not detected:

Shut down your computer and make sure the AirPort Extreme Card is oriented properly and that it is completely inserted into the AirPort Extreme Card slot. Make sure the AirPort antenna is securely connected to the card and the connector on the other end of the card is firmly inserted into the connector in the AirPort Extreme Card slot.

If you are unable to detect the network you want to connect to:

Make sure that you are in range of an AirPort base station. The typical range for an AirPort network is up to 150 feet (45 meters) in any direction from the base station.

Try to move away from possible sources of interference, such as cordless telephones, microwave ovens, and metal walls, that may be preventing you from connecting to the network. For a complete list of sources of interference, see the document “Designing AirPort Extreme Networks” located on the AirPort CD, or at www.apple.com/airportextreme.

Step 3: If Necessary, Set Up the AirPort Base Station

If you purchased the AirPort Extreme or AirPort Express Base Station at the same time as your AirPort Extreme Card, do the following:

1If necessary, install the AirPort Extreme Card in your computer.

2Skip the rest of the steps in this booklet and set up the AirPort base station using the instructions provided with it.

Step 4: Join a Wireless Network

To join an AirPort wireless network, choose a network from the AirPort status icon in the menu bar. Enter the password for the network if necessary. If you are joining a closed network, choose Other from the list, and then type the name and password of the network.

Note: To show AirPort status in the menu bar, open System Preferences and click Network. Choose AirPort from the Showpop-upmenu, then click AirPort. Select the “Show AirPort status in menu bar” checkbox.

Joining a 128-BitEncrypted Wireless Network

If you want to join a third-partywireless network that requires128-bitencryption, you have two options for entering a password, depending on the password scheme the network administrator has set up.

If you were given a password that is 13 characters, you may need to use double quotation marks before and after the password. Thirteen-characterpasswords are usuallycase-sensitive.

Example: “password12345”

If you were given a password that is 26 characters, you may need to put a dollar sign ($) before the password.

Example: $12345678901234567890abcdef

If you need additional information on your 128-bitpassword, contact your network administrator.

Joining a network protected by Wi-FiProtected Access (WPA)

If you are joining a network protected by WPA Personal, enter the user name and password you were given by the network administrator. If you are joining a network protected by WPA Enterprise, in addition to entering your user name and password, you may need to enter information about the RADIUS server. See your network administrator if you are joining a WPA Enterprise network.

Setting Up a Wireless Network With Your Computer

If you create a Computer-to-Computerwireless network or set up your computer to share its Internet connection with computers using AirPort, by default AirPort uses40-bitencryption when you use a password to protect your network. Computers with128-bitcards access the network using40-bitencryption. If you want to require 128bit encryption on your network, use the128-bitpassword scheme of 13 characters in double quotation marks. Only computers with128-bitcards can join your network.

To set up your computer to share its Internet connection, open Sharing preferences, click Internet, and select how you want to share the connection. If you are sharing your computer’s Internet connection using AirPort, click the AirPort Options button and give your network a name and password.

A computer set up to share its Internet connection wirelessly is sometimes referred to as a software base station.
