Schmitz Apple has released firmware updates for AirPort Extreme and AirPort Time Capsule base stations with [1]802.11ac Wi-Fi (the tower-like models receive Update 7.7.7), as well as older AirPort Express, AirPort Extreme, and AirPort Time Capsule models with [2]802.11n Wi-Fi (Update 7.6.7). Both firmware updates fix a bug that could prevent communication between clients on the same network, improve performance with an extended guest network, and sort out potential naming conflicts with Bonjour Sleep Proxy. You must update your AirPort base station using AirPort Utility on your Mac or an iOS device with the free [3]AirPort Utility app installed (the download isn't available via the Apple Support Web page or Software Update).
