Apple has just released AirPort 1.3, a new version of the software for the AirPort Base Station and AirPort Card. (See "Going to the AirPort" in TidBITS 567.) Foremost among the changes is support for PPPoE (PPP over Ethernet), an ugly yet common technology that enables ISPs to make always-on DSL connections act like session-based connection types. A number of DSL providers, including Apple partner EarthLink, require PPPoE for DSL. PPPoE software for the Mac has generally received poor reviews, so adding it to the $300 AirPort Base Station so you don’t have to run PPPoE software on a Mac just makes the AirPort Base Station all the more attractive. Other changes in AirPort 1.3 include DHCP client ID support, enhancements to computer-to-computer mode, support for AppleScript, and access point density adjustments for sites with multiple base stations. Also, the AirPort Base Station and AirPort Card have received Wi-Fi certification, which ensures interoperability between 802.11 wireless Ethernet products from different manufacturers. The free update is a 7.4 MB download.
