When you have multiple hardwired Sonos units while still having some wireless SONOSNet will try to communicate to random hardwired units causing multicast traffic all over the place. When you have a single hardwired Sonos then it will funnel that traffic to the single hard wired unit preserving the rest of your network performance.
Got it, I mis-read your first post as all others WIRED, not wireless.
