Apple has released a couple of updates for its AirPort Utility software for OS X Lion, and also has released new firmware updates for its AirPort Base Station and Time Capsule router devices.
AirPort Utility 6.0 is available to edit and configure both AirPort Base Station, Time Capsule, and AirPort Express networking devices. Apple has updates the prior version to version 5.6 that resolves issues with accessing passwords in the system keychain, but has also released version 6.0 which implements support for configuring iCloud to remotely access mass storage attached to the AirPort and Time Capsule devices. The updates require OS X Lion version 10.7.2 or later to install.
The firmware updates are available to address problems with wireless performance, and also provide support for accessing AirPort disks and the Time Capsule storage remotely through its iCloud service. The updates require AirPort Utility 5.5.3 or later to install, and in order to set up the remote storage access features you will need AirPort Utility 6.0 or later. The update is applicable to all AirPort Express and AirPort Base Station models that support the 802.11n protocol.
The firmware update can only be installed using AirPort Utility, so if you have version 5.5.3 or later, then you can access your device within the program to update it. The updates for AirPort Utility can be downloaded via Software Update tool in the Apple menu, but can also be downloaded from the following Web pages:
