The MyNet 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 MyNet N900 looks less attractive than other choices in top-end "N900" routers.
