There have been a number of reports from users on Apple’s support forums that the latest Airport/Time Capsule 7.6.3 firmware that was released last week seems to disable IPv6 tunnelling on various devices.
It isn’t a big surprise to many users that have experienced the functionality being disabled with past versions of the firmware, and it will likely be fixed in a future release.
Here’s how to revert back to a previous version of the firmware, if you need IPv6 tunneling functionality until Apple fixes the issue:
AirPort Utility 5
- Open AirPort Utility.
- Select your base station and choose Manual Setup, or double-click on the Wi-Fi base station icon.
- Choose Base Station > Upload Firmware…
- From the window that appears, select a firmware version and click OK. If you select Other from the Upload Version menu, you will be prompted to manually locate the firmware update.
AirPort Utility 6
- Open AirPort Utility.
- Select the base station you want to downgrade.
- Place the mouse cursor over the version number and hold down the Option key to turn it into a pop-up menu. Press and hold the mouse button to open the menu.
- From the menu that appears, select a firmware version and click OK. If you select Other, you will be prompted to manually locate the firmware update.
We’ll keep you posted when Apple fixes the issue.
