Several updates to software surrounding AirPort and Time Capsule have been sent out by Apple today, each of them coming to users through Software Update. The first update is to 802.11n AirPort Express, 802.11n AirPort Extreme and Time Capsule models - in it, users get an issue fixed for wireless performance amongst other smaller issues. The other update is for AirPort Utility 6.0 for Mac OS X Lion, it being an update for you to more effectively manage your Wifi network and AirPort base stations galore.
The AirPort Base Station and Time Capsule Firmware is being upgraded to version 7.6.1 and will allow you to get remote access to an AirPort disk or a Time Capsule hard drive with your own iCloud account. This upgrade will be to your Firmware and should be done only AFTER you grab AirPort Utility 5.5.3. Additionally, you should have AirPort Utility 6.0 at least (this being the other part of the upgrade) as well as Mac OS X Lion version 10.7.2 or later so that you might work with iCloud. Update all of this via your Software Update screen under the apple in the upper-left of your screen.

You'll be able to change base station and network settings, manage advanced features including wireless channels, security modes, and more, and all of it from this download site.
