Forget Cin Dyment for a moment….
And forget bandwidth for a moment as well…
And certainly disregard whatever Freddy says….
What is wi-fi? An “antenna “ so to speak, converting the internet signal for your streamer. Very simplistic, I know. You really think there is no audible noise from the conversion process bringing internet streaming to your streamer? Think. Antennae. In other words, look it up. Google it. No electrical noise ?
Obviously as @audphile1 says:
Before spending money on all these tweaks, invest in better quality components. No switch or ethernet tweak will bridge the gap between a low/midfi component and a high end one. No matter how many of these tweaks you throw at it. You just can’t polish the turd.
So yeah, there is that. Don’t expect magic.
why don’t you explain how electrical noise enters anything through the wifi antenna? Come on, you said it was easy to Google.
