Top critical review
Lack of functionality with streaming tv devices.

Speed and extension is great.
However, you cannot force a streaming dongle onto a specific wifi frequency and so Google Chromecast, which claims 2nd gen can handle 5ghz but that is a different review, (and I have heard) Roku does not work with this about half the time which can be frustrating.
It seems like you should be able to limit certain devices to certain frequencies. This might be a Amazon vs Google situation.
