AirPort is a simple and fast way to access the Internet from anywhere in your home, classroom, or office without cables, additional phone lines, or complicated networking software.

AirPort is a wireless local area network (WLAN) technology that provides high- performance wireless communication between multiple computers and the Internet. When you connect to the Internet using AirPort, you can share a single Internet connection with many computers at the same time and share files among them.

To use AirPort to access the Internet, you may need an account with an Internet service provider (fees may apply) and a way to access the Internet???either through a DSL or cable modem, or an Ethernet network. If your base station has an internal modem, and you have a PPP dial-up connection with an ISP, you can connect to the Internet using the base station???s internal modem.

Note: This manual includes information for setting up the AirPort Extreme Base Station using Mac OS X and Windows XP and Windows 2000. The screenshots and general instructions are based on Mac OS X. For more detailed Windows XP and Windows 2000 instructions, see AirPort Help in the AirPort Admin Utility on computers using Windows.

About the AirPort Extreme Base Station

The AirPort Extreme Base Station establishes a wired connection to the Internet or a network and wireless connections to wireless client computers. Once the base station is connected to the network, all wireless client computers can connect to the Internet by joining the AirPort network. Computers connected to the AirPort network by Ethernet can also share the base station???s Internet connection. The base station manages communications between the Internet and the wireless client computers.

The AirPort Extreme Base Station has the following ports:

???10/100Base-T Ethernet WAN () port for connecting a DSL or cable modem, or for connecting to an existing Ethernet network with Internet access

???10/100Base-T Ethernet LAN (G) port for high-speed connection to local printers and Ethernet computers that don???t have Internet access

???USB port () for connecting a printer to the base station

Some models of the base station also have a built-in 56K modem port (W) for dial-up Internet access with a standard telephone line.

Some models of the base station can also receive power over Ethernet (PoE). When the base station Ethernet WAN port is connected to IEEE 802.3af-compliant Power Sourcing Equipment (PSE), such as a line-powered Ethernet switch or hub, with a CAT 5 Ethernet cable, it receives power over the Ethernet cable.
