I have stereo paired Beosound 2 Gen 3’s. The WyFi in our area is terrible. However, they do work (sometime) paired on WyFi, sometimes (unexplainable) not. They always work on Bluetooth. Not being a rocket scientist this would lead me to believe it is a WyFi problem not a speaker problem. I cannot do anything about the WyFi but could this be a router problem? Any suggestions? Type of router ??? thanks
