Yes, I think we are saying the same thing. The Taiko Router would have to be connected to the Eero as there is no way I can hardwire the Taiko Router to the main router in my setup.
So in my diagram, the Taiko Router is wired to the Eero. Eero is getting all data wirelessly from the Eero connected to the modem.
Would this cancel out most of the benefits?
This is what I have now, I would just be inserting the Taiko Router between the Eero and the Taiko Switch.
It looks like the Extreme would not be isolated from the Apple TV which would reduce the advantages of having an audio-only network.
