Hello,
My symptoms included things like studdering video, choppy video, and sound loss. My WD box would also not connect to my network, even thought it saw it there with 2 bars.
Turns out it was my darn Pioneer wireless subwoofer!
If I turned on my sound bar first, and then my WD box it could not connect to the network.
If I turned on my WD box first, it was fine!
I am going to ditch this sound bar with wireless sub and that will stop the interfereance.
Hope this helps everyone.
