If you work in a cross-platform environment or have Windows systems on your home network, you may be interested in Apple’s latest software release.
AirPort Admin Utility for Windows 1.0
gives Windows users the same basic functionality in configuring an AirPort Base Station as their Mac counterparts.
Apple notes that this is an unsupported development version of the utility and only works with the newest AirPort Base Station (white), not the old graphite version.
The utility can be used to configure advanced base station settings such as channel frequency, closed networks, base station density, multicast rate, DHCP lease time, access control and port mapping.
System requirements include Microsoft Windows 98, Windows 2000 or Windows XP, and a dual Ethernet AirPort Base Station. Apple also notes that if you are using this with the non-US versions of the AirPort Base Stations, you will only have access to channels 1 to 11. AOL is supported in the US only.
