A very late follow up to my earlier post about some issues I was having running WPA2 wifi security and streaming movies to my AppleTV.

Since updating to Apple Airport Utility 5.5.1 and changing my wireless settings to “802.11n only (5GHz) - 802.11b/g/n” I’m now able to run WPA2 Personal security with none of the buffering issues faced earlier.

The 802.11n only setting I’m using is not one of the default options, to access this mode you’ll need to press and hold the Option key as you click on the “Radio Mode” drop down as shown below.
