Apple has posted an update to the software for its AirPort base stations. The new 4.2 update is available for download through Mac OS X’s Software Update system preferences pane and from Apple’s Web site.
“This update fixes compatibility with Wi-Fi Protected Access (WPA2) security software on AirPort Express and AirPort Extreme base stations. This update also resolves IPv6 link local configuration issues,” Apple said.
Separate downloads are available for AirPort for Windows, AirPort for Mac OS X v10.4.2 “Tiger” and Mac OS X v10.3.3 or higher. The update is suitable for all models of Apple’s AirPort base stations, including AirPort Extreme and AirPort Express models.
WPA2 support requires a Mac equipped with an AirPort Extreme card, according to Apple. Wired Protected Access 2 (WPA2), or IEEE 802.11i, is security for wireless networks that incorporates Advanced Encryption Standard (AES) block cipher technology.
