Late Wednesday, Apple released AirPort Utility 5.5.1, a 10.2 megabyte download which offers the following fixes to the AirPort Utility software:

- Not importing all settings when importing a configuration.

- Not propagating MAC address control lists when using an extended network.

The company also released a firmware update for its Time Capsule and late 2009 AirPort Extreme Base Station devices. The updated firmware repairs a problem with wireless performance in the 5GHz band and an issue with creating a Guest Network in that same band.

Both updates require Mac OS X 10.5.7 or later to install and run and the AirPort Utility update can be located, snagged and installed via Mac OS X’s Software Update feature or via the update feature in Airport Utility itself.
