ASUS RT-N56U "Black Diamond" Wireless Router Review
Wireless Performance – Lab Test – ASUS USB-N66 (High Power)
My current favorite Wi-Fi adapter is the ASUS USB-N66 that shined in our testing of it in a previous review. A unique looking 3x3:3 Wireless-N adapter; the USB-N66 has put up the fastest wireless speeds we’ve seen to date with just a bit over 230 Mbps in some tests. We will only be using the ‘High Power’ setting on the USB-N66 as that setting showed a marked improvement over the “Standard Power” settings in most tests. Let’s check out how the USB-N66 performed on all the routers at 5 GHz first.
Where the ASUS RT-N56U dominated the other routers in the ping tests with the Intel Centrino N, some of our ping tests here at 5 GHz we see the opposite. The RT-N56U comes in or ties for last place in most tests. The one bright spot is that the maximum ping time much lower on the RT-N56U compared to the others, by almost three times in some cases.
Download tests with the ASUS USB-N66 at 5 GHz are a lot closer race with all the routers running neck and neck in most categories. Only Minimum download speeds showed any real differences, and even then, we’re only looking at a difference of 31.1 Mbps between the fastest and slowest test results.
Upload speeds are an even tighter race with none of the results showing more than a 5 to 10 Mbps difference between the fastest and slowest. So, now let’s check out how things fare at 2.4 GHz.
The ASUS RT-N56U once again does great in almost every ping test, only giving up ground with Minimum ping times. Maximum ping times show a huge differential between the three routers with only 24 ms on the RT-N56U, 209 ms on the Apple Airport, and a whopping 367 ms on the RT-N66U.
At 2.4 GHz we see the RT-N56U taking it to the competition and leading in both average and minimum download speeds. The only test it fell by the wayside was Maximum Downloads with a speed of 86.4 Mbps versus the RT-N66U’s 107.8 Mbps and the Apple’s 112.7 Mbps.
Again, but this time in 2.4 GHz upload speeds, the ASUS RT-N56U does great, beating the Apple Airport and ASUS RT-N66U in both Average and Minimum Speeds. The RT-N66U Maximum upload speed of 78.8 Mbps is the only test that tops the RT-N56U’s speed of 61.7 Mbps while the Apple Airport trails behind with 56.4 Mbps.
