We tested the wireless performance in various scenarios to see how the Asus RT-N56U performed in typical real-world situations for both its 2.4GHz and 5GHz modes.
The first was a same-room configuration transferring a large file from the router to the laptop. The second involved the laptop being placed one brick-wall and a standard wooden floor away.
Finally we ran a distance test at 30m with a direct line of sight, to see how it coped with distance.
