I have several Sonos one speakers and 2 Era 100s. They were all working fine. I get a message that the Era speakers need an update and when I started the update I got Error Code 30. I called support and they say that the Era speakers will not communicate with my Spectrum router. But they used to work on this router until the update. I’m about ready to return the speakers. Any ideas on how to get them to work?
