Apple earlier this week began shipping its new 802.11n-enabled AirPort Extreme, which provides not only faster networking connectivity using the latest 802.11n WiFi standard, but also offers shared network storage via USB connection, a built-in three-port Ethernet router, a built-in firewall for security protection, and timed access controls for parents. The new software can control the new 802.11n-enabled base stations as well as older Apple-branded base stations and features a new software wizard to easy setup, improved UI, better responsiveness, and more features for new devices. Apple also posted new troubleshooting documents related to the new devices as well as offered a new AirPort Disk Utility (CD-only) for locating shared storage volumes. The AirPort CD software also includes the 802.11n software enabler for Core 2 Duo-based Macs--for which Apple is charging $1.99 to download; the patch enables other users to use the faster wireless connectivity standard without purchasing Apple's base station.
