Apple’s Software Updates Web site recently listed AirPort version 1.3.1, for Mac OS 9.0.4 or later. Separate downloads are available for North American and International English versions of the Mac OS.
AirPort is Apple’s brand name for wireless networking cards and base stations available for all newer Mac models. The products utilize industry standard IEEE 802.11b technology for wireless communication. “Wi-Fi” certified, the AirPort cards and base station enable Macs to communicate up to 150 feet apart at speeds up to 11 Mbps — comparable to conventional 10baseT Ethernet.
The latest major revision of AirPort, 1.3, was released in March. That version added support for Point-to-Point Protocol over Ethernet (PPPoE) and DHCP Client ID. There was no immediate word from Apple about what changed in this minor release.
