ethernet connection or wireless connection is one better than the other
Best answer by Stanley_4
Not a “better” matter but there are differences.
I like putting my Sonos traffic on wires where possible and keeping the rest of it on a different channel than my home WiFi data. I can load up either without impacting the other.
In WiFi (Standard) Mode you have to set your home WiFi to be compatible with the Sonos requirements. See the Support FAQ.
In Wired (Boost) Mode you can use all the abilities of your home WiFi with no Sonos imposed restrictions other than all must be on a single LAN. So things like not allowing B/G connections, enabling Airtime Fairness, multiple APs on different channels and the like are possible.
