Apple AirPort Extreme 5.0.3 Firmware Update

This firmware update is just for the new AirPort Extreme Base Station, not the original graphite or snow Base Stations. From the KBase article,

"This firmware update fixes an issue where an AirPort Extreme network appears to be unavailable as displayed by the AirPort Menu Extra or the Internet Connection application. This behavior may result from excessive 2.4 GHz radio interference which causes the wireless network to disappear. The update allows the base station to more gracefully recover when exposed to sources of interference. For additional information on reducing the effects of interference, see the Apple Knowledge Base document "AirPort: Potential Sources of Interference.

"The AirPort Extreme Base Station will no longer spontaneously restart itself.

"There is now no known limit to the number of FTP connections that can be initiated through the base station."
