WiFi Streaming Versus An Ethernet Cable Connection

My streamer is ethernet connected to a Mesh router upstairs. In order to minimize noise, no other hardware piece is connected to this Mesh router. The main router (connected to the modem) is downstairs. It is possible to move the modem upstairs (to connect it directly to the router that feeds the streamer) but I always thought less hardware connected to the router connected to the streamer is better. 

Am I right? 

Any difference 'noise wise' using the main router or the Mesh / Satellite one?

PS : I do not have any dropouts issues

PS2 : As far as I know, I can disconnect wifi on these routers (Eero)

@cagma7 I use EERO exactly the same way you do. If you can hardwire directly from the router, definitely give it a shot. 
Otherwise, get a good ethernet cable for EERO to streamer connection and you are good to go.

@x5owner1 

it’s more likely the poorly timed data coming out of the router. A switch will re-clock the data so the Bryston will have an easier time re-clocking it (again) before it sends it on to the internal DAC section.

a switch will not and cannot reclock anything. That is not what a switch does.

If you are leaning towards inserting a switch between your router(modem) and streamer, I would look into LHY SW-6 Ethernet which checks all the boxes. I ordered one last week to try it out in my 2nd system.

Hmmm….Hans Beekhuyzen seems to think there are clocks in switches.  And voltage regulation.  And he has been involved in digital audio for 40+ years.  And he uses audiophile switches in his systems.  Why, I wonder?
