New Delhi: Apple has released a firmware update for two router models, the AirPort Extreme and AirPort Time Capsule. Both products were refreshed in 2013 with 802.11ac Wi-Fi capability. The older AirPort Express and other discontinued models do not require the patch.
In a very brief release note posted to its support database and initially reported by Macworld, Apple only states, "Firmware update 7.7.3 is recommended for all AirPort Extreme and AirPort Time Capsule base stations with 802.11ac. It provides security improvements related to SSL/TLS. Other AirPort base stations do not require this firmware update."
