Because of your previous recommendation of the Cisco I checked into it and all of the comments I read on it said the same thing: unreliable for streaming lossless bitrate BD rips. If I want to lower the bitrate of my rips the network stuff I have now would work fine (I’m also on a dual-band setup with the 5ghz channel dedicated to the Live Hub), but I don’t want to lower the quality. I can sometimes get 20 minutes into a MKV movie before it starts glitching, but usually it takes less than 5. It’s easier for me to copy any BD rips I want to see to my Toshiba 3tb USB drive and plug it into the Hub and watch them locally instead of trying to stream them wirelessly. They play flawlessly that way.
