Why people don’t isolate wifi entirely from audio system is a mystery to me, wifi shouldn’t exist on audio system network, routers with wifi enabled and then adding another component (switch) is not optimized network for steaming.
I have read in the past the best strategy is to have a separate network and I don’t know exactly how one does this. If we use a remote such as an ipad to control streaming how is it possible to not have wifi? I think my system sounds pretty good, but always looking for the next networking trick to improve sound.
I haven’t searched yet- and I'm sure I am not the only one wondering: Do you have a link to a guide which explains what one should do?
