I have 15 Sonos speakers + 2 surrounds connected via a Sonos amp. I usually have no problem playing audio in multiple rooms. I recently added an Era 300 and now my system is unstable. The music will drop out of random rooms. I have Eero 6 Pro WiFi with Gigabit Ethernet. I was previously using SonosNet to keep the speakers off my primary WiFi but ERA 300 only connects via WiFi. Is there something I need to do to make sure my configuration is stable?
