Schmitz Apple has released [1]AirPort Base Station Firmware Update 7.6.4 to correct three specific issues on all 802.11n AirPort base stations (AirPort Extreme, AirPort Time Capsule, and AirPort Express). It fixes a problem that could cause an intermittent loss in Wi-Fi connectivity with iOS devices and addresses an issue that could cause an AirPort Time Capsule to report that the backup disk is in use. Additionally, the update fixes an IPv6 Tunnel error that was [2]introduced with Firmware Update 7.6.3. You can update your Airport base station using Airport Utility via either your Mac or an iOS device (with the free [3]Airport Utility app installed). Click or tap the base station with a red circle sitting to its right, then click the Update button on the Mac or tap Version > Download and Install on your iOS device.
