AirPort Time Capsule 802.11ac

Michael Brown:

Based on my experience testing 802.11ac routers with Windows machines, I expected the 802.11ac Time Capsule to be considerably faster than the 802.11n model. And that’s certainly what my WiFiPerf results indicate. But these real-world file transfers defy that expectation.

The current theory, first published at Anandtech, is that OS X is not properly scaling TCP window size during file transfers to allow the MacBook Air’s 802.11ac client adapter to achieve peak performance. While Apple has not confirmed this to be the problem, the company is aware of the performance discrepancy and is reportedly working on a solution.

Apple has also integrated the power brick into the device and added “AirPort” to the product’s name.
