ok, about that site I've mentioned before.
they've actually made those tests themselves, and they released a video: http://www.youtube.com/watch?v=8SnmmuDcvb8

it's in dutch, and imho... it's a lot mumbo jumbo...
first of all they say that asus always had poor network products (mainly because of the firmware) compared to other routers... seriously?

then the guy starts a whole story about that 5GHz is amazing but isn't fitted in every laptop... uhu, but I don't need almost 2 minutes to tell you about it
it wasn't even about the router anymore

but yeah, in the end there's nothing new shown in the video
