@yoramguy1, I use a $100 Calix Aspire CAT6 router that was provided by our cable company, and it does its job without any fuss. My point being that you don’t need a fancy router to stream music and watch football at the same time. What you do need to do as @teknorob23 suggested is to isolate your streamer from the network. And to that end I have two moderately priced network switches with their own iFi power supplies in cascade, or in sequence back to back as it were, a decent Ethernet cable between the two switches, and then a passive ENO Streaming filter before the signal ones to my music server.
To say that I was skeptical about even trying this type of setup would be a humongous understatement. But taking things slow and going step by step eventually convinced my brain that what it was hearing sounded much better than the music did before.
