Instead of using cables to create a network, AirPort uses wireless local area network (WLAN) technology to provide wireless communication between computers. Through a wireless network you can access the Internet, share files, play multiplayer games, and more. If you have an AirPort Express and use AirPort 4.0 or later, you can play iTunes music through remote speakers using AirTunes. Using AirPort technology, you can: · Create a wireless network in your home or school using an AirPort Extreme Base Station or AirPort Express, then connect to the Internet and share the connection among several computers simultaneously. An entire family, business, or classroom can be on the Internet at the same time. · Create a wireless connection between a single computer and a standard computer network. Wireless computers can then have access to an entire network without being connected using a cable. · Connect multiple computers in a wireless "ad-hoc" network so that you can share files or play network games. · Connect a USB printer to the base station and all of the computers on the AirPort network can print to it. · If you are using AirPort Express, connect it to your stereo or powered speakers and use AirTunes to play iTunes music. You can set up an AirPort Extreme Base Station or an AirPort Express and connect to the Internet without wires in minutes. But since the AirPort Base Stations are flexible powerful networking devices, you can also create an AirPort network that does much more. 5 If you want to design an AirPort network that provides Internet access to non-wireless computers via Ethernet, or take advantage of some of the base station's more advanced features, use this document to design and implement your network. Note: This version of AirPort Admin Utility is compatible with Windows XP (with Service Pack 2 or later) and Windows 2000. The instructions and screen images in this book are for Windows XP. If you are using Windows 2000, the images on your screen may look slightly different. How AirPort Works In a wired network, sharing files and information between computers requires the computers to be connected by cables. With AirPort, the data is transferred between computers using radio waves through a wireless network. You can create a wireless network using an AirPort Extreme Base Station or an AirPort Express, and all wireless communication goes through the base station to the Internet or to other computers on the network. You can also incorporate AirPort technology into an existing Ethernet network by connecting an AirPort Extreme Base Station or AirPort Express to the network. This allows non-AirPort computers to communicate with AirPort computers. If you are setting up an AirPort Extreme Base Station, you can connect Ethernet computers to the base station LAN port (G). The typical indoor range for an AirPort connection is up to 150 feet (45 meters). Range in a wireless network may vary with site conditions. How Wireless Internet Access Is Provided Wireless Internet access requires an 802.11b or 802.11g wireless adapter, an AirPort Extreme Base Station or AirPort Express, and an account with an Internet service provider (fees may apply). Some Internet service providers (ISPs) are not currently compatible with AirPort. Some cable modem and DSL providers may not be compatible with AirPort. Contact your service provider for more information. AirPort technology is similar to cordless telephone technology. The handset of the cordless phone makes a wireless connection to the base, which is connected to the telephone system. Likewise, with AirPort, your computer does not establish a wireless connection with your ISP directly. You set up a wireless connection from the computer to a base station that is connected to the Internet by a wire, such as a DSL or telephone line. 6 Chapter 1 Getting Started Use AirPort to provide wireless Internet access and share a single Internet connection among multiple computers in the following ways: · Connect the AirPort Extreme Base Station or AirPort Express to a DSL or cable modem. (If the AirPort Extreme Base Station has an internal modem, you can connect it to a telephone line.) The AirPort Extreme Base Station or AirPort Express receives content from the Internet, such as webpages and email, via its Internet connection and then sends it to wireless-equipped computers, using the wireless network. · Connect the AirPort Extreme Base Station or AirPort Express to an existing network that already has Internet access, such as in a school or small office. Wireless computers connect wirelessly to the base station and receive network and Internet content. Configuring AirPort Extreme Base Station and AirPort Express for Internet Access Like your computer, the AirPort Extreme Base Station or AirPort Express must be set up with the appropriate hardware and Internet Protocol (IP) networking information to connect to the Internet. To provide the Internet configuration information to your AirPort Extreme Base Station or AirPort Express, you can use the AirPort Setup Assistant. The AirPort Setup Assistant asks a series of questions to determine how the base station's Internet connection and other interfaces should be set up. To set up more complex configurations, you use AirPort Admin Utility. For more information about the AirPort Setup Assistant and AirPort Admin Utility, see the following sections. AirPort Setup Assistant Use the AirPort Setup Assistant to enter the settings your AirPort Extreme Base Station or AirPort Express needs to connect to the Internet. Enter the settings you received from your ISP for Ethernet, PPP over Ethernet (PPPoE), or the internal modem if your base station has one. You can also give your AirPort network a name and password. You can use the AirPort Setup Assistant to set up a base station as a wireless bridge and extend the range of your existing AirPort Extreme or AirPort Express network. If you are using an AirPort Express, you can create a new wireless network or join an existing wireless network. If you connect AirPort Express to your stereo or powered speakers, you can set up your AirPort Express to play iTunes music using AirTunes. See Chapter 4, "Using AirPort Express," on page 57 for more information. Chapter 1 Getting Started 7 To use the AirPort Setup Assistant, you need an AirPort Express or an AirPort Extreme Base Station, the AirPort Setup Assistant (on the CD that came with AirPort Express or the AirPort Extreme Base Station), Windows XP with SP2 or later or Windows 2000, and AirPort 4.0 or later. To play music using AirTunes, you need iTunes 4.6 or later. AirPort Admin Utility The AirPort Admin Utility is a convenient way to make quick adjustments to your base station configuration. Use AirPort Admin Utility to: · Set up an AirPort Extreme Base Station or AirPort Express to provide Internet access to computers that connect to the base station · Change settings, such as the phone number for your ISP if your base station has a modem, Internet setup or your ISP account settings · Configure advanced base station settings, such as channel frequency, security options, closed networks, DHCP lease time, access control, WAN privacy, power controls, port mapping, renaming a USB printer, or, if your base station has a modem, remote dial-in For instructions on using AirPort Admin Utility, see "Using the AirPort Setup Assistant" on page 18. Extending the Range of Your AirPort Network You can extend the range of your network by setting up wireless connections between multiple base stations in your network, known as a Wireless Distribution System (WDS), or connecting multiple AirPort Extreme Base Stations via Ethernet to create a roaming network. If your base station has an antenna port, you can also extend the range of your wireless network by connecting an Apple-certified external antenna to the antenna port. For more information on setting up a WDS or a roaming network, see "Connecting Additional Base Stations to Your AirPort Network" on page 42. Note: If you are using AirPort Express to extend the range of your AirPort Extreme or AirPort Express network, see Chapter 4, "Using AirPort Express," on page 57. Some models of the AirPort Extreme Base Station can receive power through the Ethernet WAN port when connected to 802.3af-compliant Power Sourcing Equipment (PSE) with a CAT 5 Ethernet cable. A PSE is a line-powered Ethernet device, like a switch or a hub, that supplies power to Powered Devices (PDs) over the Ethernet cable. Powering the base station using a PSE is known as Power over Ethernet (PoE). 8 Chapter 1 Getting Started If your base station can receive power over Ethernet, the base station and the mounting bracket conform to UL Standard 2043, "Fire Test for Heat and Visible Smoke Release for Discrete Products and Their Accessories Installed in Air-Handling Spaces," for placement in the air-handling space above suspended ceilings. Using Power over Ethernet allows you to install a base station in places away from a standard electrical outlet. For more information about using PoE, see the documentation that came with your base station. To use the base station in an air-handling space above suspended ceilings, you must connect the Ethernet WAN port to an 802.3af-compliant PSE with a plenum-rated Ethernet cable. You cannot use the AC power adapter to power a base station installed in an air-handling space. When the base station receives power over Ethernet, the USB port is disabled. Do not connect an external antenna to a base station mounted in an air-handling space unless the antenna conforms to UL Standard 2043. Some external antennas are not compliant. AirTunes If you are using AirPort Express, and you have connected it to your stereo or powered speakers, you can play iTunes music on the stereo using AirTunes. AirTunes is an encoding technology that allows for CD-quality transmission of iTunes music over the air. You can stream music from your iTunes library to AirPort Express, and AirPort Express plays the music on your stereo through cables connected to the analog and optical digital audio stereo mini-jack. The music is buffered to help ensure smooth playback without skips or jumps. Anything you play in iTunes--MP3 files, AAC files, audio books, even Dolby surroundsound--you can play using AirTunes. To use AirTunes, you need an AirPort Express connected to your stereo or powered speakers, AirPort 4.0 or later, and iTunes 4.6 or later. Printing via an AirPort Extreme Base Station or AirPort Express If you have a USB printer connected to the AirPort Extreme Base Station or AirPort Express, computers on the network can print to the printer by setting it up in Windows XP or Windows 2000. For detailed instructions on setting up a printer connected to the base station, see "Connecting a USB Printer to the AirPort Extreme Base Station or AirPort Express" on page 53. Note: If your AirPort Extreme Base Station supports PoE, and is receiving power from an 802.3af-compliant PSE, do not connect a printer to it. Chapter 1 Getting Started 9 Sharing Your Computer's Internet Connection If you have a wireless card installed in your computer and you are connected to the Internet, you can share your Internet connection with other computers. This is sometimes called using your computer as a software access point. You can share your Internet connection as long as your computer is connected to the Internet. If your computer goes to sleep or is restarted, or if you lose your Internet connection, you need to restart Internet sharing. To start Internet sharing: 1 Open Control Panel and double-clic ...
