Time Capsule and AirPort Extreme Base Station Firmware Update 7.5.1 brings fixes for a pair of issues on Apple’s latest AirPort Extreme and Time Capsule base stations released last October
.This update provides several fixes for the latest Time Capsule and AirPort Extreme Base Station (Late 2009) including:
– An issue with wireless performance in the 5GHz band
– An issue with creating a Guest Network in the 5GHz band
Issues with 5 GHz performance on the new base stations had been well-documented, and users noted earlier this month that models had begun shipping with the 7.5.1 firmware version that seemed to address the problem. Today’s release, which is accessible through AirPort Utility, extends the fix to existing devices.
In order to support the new firmware version, Apple has also released AirPort Utility 5.5.1 for Mac OS X (10.24 MB) and Windows (10.70 MB). The updates also offer fixes for several other minor issues.
