The ASUS N66U continued to flaunt its brilliant showmanship on the 5GHz band. In a nutshell, its downlink speeds were simply unmatched by its adversaries. If you can keep your eyes trained on the bright blue bars below, you'll see that the N66U's throughput figures blazed the trail right up to 25 meters, where it was eventually edged out by the N56U by a notch. Peak throughputs were measured as 109.732Mbps at 2 meters, and 100.499Mbps at 10 meters. Similar to our findings on the 2.4GHz band, this router's performance at 10 meters was the best by far. The N66U also impressed with WPA2 encryption thrown into the mix, judging by its average throughput of 110.717Mbps which topped the rest of the routers as well. So if you are planning to stream media files via this router, chances are you won't be too disappointed with its downlink abilities. You might want to note that these results were based on the router being clamped in 802.11n-only mode with channel bonding (40MHz) enabled. We couldn't ascertain if there was a higher level of interference at the 5GHz band during our tests, but the N66U's upstream speeds were significantly slower than the N56U. Nonetheless, it did produce more optimal results than the Trendnet 692GR for all of the upstream tests.
