Apple today announced the second generation of its AirPort technology, which adds support for America Online to the Base Station, a built-in firewall, 128-bit encryption, and support for up to 50 users. Pricing remains the same, at US$99 for the AirPort card and $299 for the Base Station. Apple has also released AirPort Software 2.0, which upgrades all AirPort cards to 128-bit encryption (Base Stations remain at 64-bit). The software can be downloaded via Software Update.
