AirPort Utility, formerly known as AirPort Admin Utility, is a program that allows users to configure an AirPortwireless network and manage devices attached to the Base Stations. It comes pre-installed on OS X, and is available to download for Microsoft Windows and iOS. It provides a graphical layout of AirPort devices attached to a network, and provides tools to manage each one individually.
AirPort Utility allows users to configure their network preferences, and assign Back to My Mac accounts to the network. It also provides the ability to configure USB devices, such as Printers, attached to the network, as well as customising AirPlay device options. Networks may include AirPort Express and Extreme Base Stations, as well as Time Capsules. It also provides features such as Timed Access Control, permitting connections depending on a pre-defined schedule, and the ability to configure a Guest Network. The latest version of the software for OS X, however, forgoes some of the functionality of previous iterations. Dropped functions include the ability to see a list of wired DHCP leases. Users of newer versions of OS X wishing to restore these lost functions could exploit a workaround to install an older version of the application.
Apple has also released a version of AirPort Utility with iOS. This allows iPhone, iPod Touch, and iPad users to configure and manage AirPort networks without the need for a computer. Version 1.1.1 supports devices running iOS 5 or later.
