If you plan to share your Internet connection with wireless-enabled computers on
your network or computers connected to the Ethernet ports, you need to set up your
AirPort Extreme as an AirPort base station. After it is set up, computers access the
Internet through the AirPort network. The base station connects to the Internet and
transmits information to the computers over the AirPort network.
Before you use AirPort Utility to set up your wireless device, connect your DSL or cable
modem to the AirPort Extreme Ethernet WAN port (<). If you are using an existing
Ethernet network with Internet access to connect to the Internet, you can connect the
AirPort Extreme to the Ethernet network instead.
Use the setup assistant in AirPort Utility to enter your ISP settings and configure how
the AirPort Extreme shares the settings with other computers.
Choose the wireless network you want to change. On a Mac, use the AirPort status
menu in the menu bar. On a computer using Windows XP, hold the pointer over
the wireless connection icon until you see your AirPort network name (SSID), and
choose it from the list if there are multiple networks available.
The default network name for an Apple base station is AirPort Network XXXXXX,
where XXXXXX is replaced with the last six digits of the AirPort ID, also know as the
Media Access Control or MAC address. The AirPort ID is printed on the bottom of an
Open AirPort Utility, located in the Utilities folder in the Applications folder on
a computer using Mac OS X, or in Start > All Programs > AirPort on a computer
Select your base station and click Continue.
Follow the onscreen instructions to configure and share Internet access on your
Using AirPort Utility is a quick and easy way to set up your base station and network.
If you want to set additional options for your network, such as restricting access to your
network, or setting advanced DHCP options, you can choose Manual Setup from the
Base Station menu of AirPort Utility.
