We got our new Airport Extreme 802.11n today. We decided to deviate from our standard modus operandi and run some benchmarks before we took it apart. (I know, I know-- our screwdrivers were lonely for a while.) This image is a sneak-peek to get your appetite whetted.
The new base station is amazing. We achieved a 10x performance boost, and a 3x usable range increase (significantly better than Apple's 5x/2x claims). Actual benchmarks are on the next page.
