Spent an hour with Sonos support yesterday and they couldn't help me fix the problem. Spotify won't work while other services like TuneIn and Pandora work fine. THis problem started for me when I switched to a Mesh router. Has anyone else had an issue with Mesh routers like Netgear's ORBI system?
Hey...im sure you have already done this, but if not, see if you can upgrade the code on the ORBI. Sonas uses Spanning Tree protocol and multicast packets. the ORBI might not be handling that correctly. There also might be options in the ORBI to change the behavior of the STP and Multicast packets.
That sounds interresting. I use the Mesh System from AVM (Fritz!Box). Maybe there is a Problem with the latency. My problem solved itself after a while (about a week). Can you try to connect the System via cable?
