The new AirPort Update 2005-001 1.0 (776K) is available through Software Update and also by direct download from the company.

Customarily terse notes that accompany most Apple software releases reveal: "This update fixes reliability and resolves AirPort compatibility issues with certain third party 802.11 cards and access points for Mac OS X v10.4.3 and later."

The software is for Mac OS X 10.4.3 and later and requires an AirPort Extreme card.
