Apple has updated its AirPort Express and AirPort Extreme firmware for both Mac and Windows users.

The version 6.1.1 updates improve reliability and resolve some printer compatibility issues.

According to Apple, the firmware updates offer improved hard reset behaviour; improved reliability of WDS networks when using WPA security; resolve an issue with inbound passive FTP to a port-mapped computer on the network; and fix an issue with certain printers which were no longer recognized by the base station after the last firmware update (6.1) was installed.

The AirPort Extreme update also resolves a potential problem with PPPoE configurations when updating from 5.4 or earlier.

The updates are available on Software Update or on Apple's Web site.
