Apple has updated the firmware for the TimeCapsule a few days ago, and updated the AirPort Utility software to version 6. Which might not be exactly what you were waiting for…

The user-interface of AirPort Utility 6 is completely new, it looks exactly like the iOS AirPort Utility interface now…

the good :

• direct visual insight in how your local WiFi-network is set up (in a nice tree-branche structure)
• by clicking on the hardware icons, you will see info like Network name, IP address, Serial no., Firmware version and… a list of all currently connected wireless clients
• if your Firmware is out of date, you will see that instantly because of the little red circle with the white 1 in it next to the hardware icon
• full iCloud support

the bad :

• this is not an Administator interface, it’s nothing more than a nice looking info&update-utility, but as all options for managing your WiFi-network and your AirPort-hardware have vanished…
• this app is MasOSX 10.7 “Lion” only…
• from now on, it’s iCloud-only – no support for MobileMe any longer… (so no iDisk any longer…)
• you can not manage AirPort-networked printers (like the USB-printer connected to your TimeCapsule) any longer
• some client devices may not be able to find the updated AirPort Basestation / TimeCapsule (my iPhone 4 needed a reboot to become able to connect…)
• …the printer-timeout-problem still exists, this update doesn’t resolve issues with the TimeCapule not being able to temporarily save big files that the connected USB-printer can not process quickly enough…

the ugly (the dirty way to get everything) :

…luckily, it is possible to re-install and use the previous version of AirPort Utility alongside of this one (eventhough the version 6 installer deletes the previous version) :

• either place the previous version back into your “Utilities” folder (inside your “Applications” folder) from your TimeMachine-backup ; be sure to change the name of the old version to something like “AirPort Admin Utility” since it won’t be possible for both of them to use the “AirPort Utility” name…
• or… download the installer of the 5.6 version from Apple :
