If the units are also wifi connected (sonos mesh networking), then either only plug in one of them to ethernet, or fiddle with your switch spanning tree cost values. As I recall, sonos uses the older standard spanning tree values, and until I fiddled with my managed switch settings, the sonos were regularly bringing down my local network, and/or winning the elections so that large amounts of my lan traffic went over their wireless mesh network.
Pretty crappy default configuration on Sonos' part (using old default cost values), if you ask me.
- cm2187 9y agoNo I never configured the wireless setup, I wired them to ethernet straight away.
- rblatz 9y agoThey self configure into a wireless network called sonosnet if they are wired together.
- cm2187 9y agoHow do I switch that off then? I don't see any option in the windows sonos app's settings. I just see a Advanced Settings/General/Wireless Setup but that's to connect it to a wifi, which I do not want to do.
- stock_toaster 9y agoIndeed. There is a way[1] to connect to the individual sonos units and disable the radio entirely, but that certainly isn't the default. [1]: https://bsteiner.info/articles/disabling-sonos-wifi https://bsteiner.info/articles/disabling-sonos-wifi
- cm2187 9y agoIt's not just not the default. It's actually hard to find. You can't do that from the Sonos applications.
- stock_toaster 9y agoI agree. It seems pretty bonkers, but I'm sure some PM thought it would be great for some subset of customers to just be able to plug things in and have things "magically work". Anything beyond the most basic network though, and it really causes problems.
- pantsofhonking 9y agoBest thing to do in most situations is unplug everything, disable SonosNet, use ordinary WiFi.
- stock_toaster 9y agoI eventually ripped out my custom switch configs and went with a single Sonos unit hard wired, and the rest on SonosNet/Mesh. I use only 5ghz wifi (2.4ghz disabled) at home, and since Sonos only does 2.4ghz wifi, this was the best solution for me.
- crummy 9y ago^ I worked in Sonos support for 7 years and going wired for everything is the best configuration - if you're still having issues with that then spanning tree configuration is the likely cause.
- blktiger 9y agoI found Sonos support to be super helpful. First time I've talked with a support representative where I came away impressed with how knowledgeable they were.
