Apple Update Firmware of Airport Extreme
Apple has updated its AirPort Extreme firmware to version 5.3 for Mac OS X and Windows networks. The 1.5MB download is available from Apple's support Web site and is not for use with the original Graphite or Dual Ethernet/Snow AirPort Base Stations. Explanatory notes on the software available from Apple state that the release "includes support for the Wi-Fi Protected Access (WPA) specification for the base station." WPA increases data-protection and access-control on wireless networks.
