Set up your Apple wireless device manually using AirPort Utility when:

ÂYou want to provide Internet access to computers that connect to the wireless device using Ethernet

Âyou’ve already set up your device, but you need to change one setting, such as your account information

ÂYou need to configure advanced settings such as channel frequency, advanced security options, closed networks, DHCP lease time, access control, WAN privacy, power controls, or port mapping or other options

For instructions on using AirPort Utility to manually set up your wireless device and network, see “Using AirPort Utility” on page 15.

Extending the Range of Your AirPort Network

You can extend the range of your network by using AirPort Utility to set up wireless connections among several devices in your network, or to connect a device using Ethernet to create a roaming network. For more information on extending the range of your network, see “Connecting Additional Wireless Devices to Your AirPort Network” on page 41.

Sharing a USB Hard Disk Connected to an AirPort Extreme Base Station or Time Capsule

If you’re using an AirPort Extreme Base Station or a Time Capsule, you can connect a USB hard disk to it, and computers connected to the network—wired or wireless, Mac or Windows—can share files using the hard disk. Every Time Capsule includes an internal AirPort disk, so you don’t need to connect an external one. If you want, you can connect additional USB disks to the USB port on your Time Capsule. See “Sharing and Securing USB Hard Disks on Your Network” on page 54.

Printing with an Apple Wireless Device

If you have a compatible USB printer connected to your Apple wireless device, computers on the AirPort network can use Bonjour (Apple’s zero-configuration networking technology) to print to the printer. For instructions about printing to a USB printer from a computer, see “Connecting a USB Printer to an Apple Wireless Device” on page 55.

Sharing Your Computer’s Internet Connection

If your computer is connected to the Internet, you can share your Internet connection with other computers using Mac OS X version 10.2 or later, or Windows XP with Service Pack 2. This is sometimes called using your computer as a software base station.
