Wireless Performance - 5 GHz, Two Stream

For performance comparison, I chose the same set of routers as in the original review: the ASUS RT-N66U "Dark Knight"; Cisco Linksys E4200V2; and NETGEAR R6300. Here is the Performance Table for 5 GHz, 2 streams

As noted earlier, I was able to take measurements in Location D for all test runs. None of the selected routers won in all four benchmarks, although the ASUS was the strongest performer running downlink in both 20 and 40 MHz bandwidth modes.

On the other hand, the WD turned in the highest throughput measurement of 128 Mbps in Location A running uplink in 40 MHz mode. To balance out that positive, note that the WD tended to have the lowest Location D (weakest signal) throughput.

The IxChariot plot below for 20 MHz mode downlink shows generally stable throughput.

This is also the case in most of the other plots linked below, albeit with higher variation shown in the 40 MHz mode plots.

• 5 GHz / 20 MHz uplink
• 5 GHz / 20 MHz up and downlink
• 5 GHz / 40 MHz downlink
• 5 GHz / 40 MHz uplink
• 5 GHz / 40 MHz up and downlink

Wireless Performance - 5 GHz, Three Stream

Here is the Performance Table for 5 GHz, 3 streams. The ASUS is the overall winner in this comparison, taking three out of four benchmarks. But, once again, the WD shows its strength with strong-signal uplink performance, coming within 5% of the ASUS in both 20 and 40 MHz modes in Location A with 103 and 136 Mbps, respectively.

The IxChariot plot below for 20 MHz mode downlink once again shows generally stable throughput for the stronger-signal location A and C runs. But with the lower signal in Location D, throughput starts to bounce around more.

You'll see the higher variation even in stronger signal runs in some of the plots linked below.

• 5 GHz / 20 MHz uplink
• 5 GHz / 20 MHz up and downlink
• 5 GHz / 40 MHz downlink
• 5 GHz / 40 MHz uplink
• 5 GHz / 40 MHz up and downlink

Closing Thoughts

The My Net N900 is not a bad first router effort from WD, with 20 MB/s + storage filecopy performance, decent feature set including free parental controls/web filtering for up to 15 devices, 700+ Mbps wired routing speeds and Ubicom-based automatic Qos.

Our initial review showed it also has some of the highest throughput I've ever seen from a three-stream "N900" router on its 2.4 GHz side. And with the properly-operating new sample, I can say the same for the 5 GHz side. But those high speeds are only running uplink and only with a very strong signal (same room or maybe next room).

When it comes to downlink performance or as signal levels drop, the My Net N900 looks less attractive than other choices in top-end "N900" routers.
