Apple has released AirPort Software 3.1, an update that integrates software patches to bring its AirPort Extreme products up to the recently ratified 802.11g standard.

The update also offers enhancements for legacy AirPort products using 802.11b: "If you are a user with an AirPort-enabled computer using an AirPort Extreme Base Station you will experience maximum data rates of 11 Mbps. However with AirPort 3.1, you'll still enjoy significant benefits, especially from the standpoint of wireless printer sharing, easy Base Station administration, and many options for managing the range of your wireless network," Apple said.

Apple says the update offers new AirPort Extreme Base Station features include:

- Base Station Interference Robustness, which provides improved performance when 2.4GHz devices such as cordless phones and wireless video-distribution systems interfere with an AirPort network;

- Automatic channel selection, so the Base Station will find the most appropriate channel to use when it is restarted;

- A simpler Wireless Distribution System (WDS) set-up experience in AirPort Admin Utility;

- Administrators can set the DHCP range on their Base Station when NAT is on; and

Performance improvements between wired and wireless clients;

New AirPort Extreme client features include compliance with the final IEEE 802.11g specification, and client-side Interference Robustness, reducing the impact of other 2.4GHz devices that can interfere with the network.

The update requires Mac OS X 10.2.6 and an AirPort Extreme-ready computer with an internal AirPort Extreme card, or an AirPort-ready computer with an internal AirPort card.
