I hate SONOS now!!!!

You mentioned:

I'm using my Beam to be the main piece of Sonos equipment and have only the Beam hardwired, everything else is using wifi. 

This only is correct if you have "disabled wifi" on the Beam. If you haven't then your other Sonosnet capable devices will ignore your wifi and connect to the Beam generated Sonosnet if possible. 

You can do the disable wifi option (not what it actually does) as you have no Sub or surrounds connected.

Personally I'd remove the Ethernet connection and avoid the issues it brings. If a wifi connection to the Beam is impossible then the disable wifi is a good fallback.

So I was told I should have at least one Sonos product connected by Ethernet cable to my eero base. This is not true and I shouldn’t have any of them connected via Ethernet? When I check each piece of equipment it says it’s using the Sonos OS:S2. I was told that is the SonosNet. Is that incorrect?

thanks for your feedback everyone. 

The code for Sonosnet is WM:0 (see Check if Sonos is in a wireless or wired setup | Sonos). S2 is the operating system you are on. When one (older - the newer devices do not do Sonosnet) device is connected by cable all (older) devices go over to Sonosnet. So if you want to go over to full wifi no device should be cable connected. 

Maybe this will help too: Recommended settings for using Sonos on wireless networks | Sonos

I don’t have an eero wifi so I’ve not bothered to read the support advice. I remembered others had experienced issues in the past, did a search, and provided you with a link to the article. Have you tried what they advise? Or are you still settling for the sacrificial chicken as the route to a fix? 

Maybe you could start a new thread with a focussed subject title such as “Help needed configuring eero network” and see if anyone comes forward with their working solution? 

 I have a Port connected via Ethernet.  It’s OK to do that as long as you turn Disable WiFi on the Sonos device connected via Ethernet.  That option, in my case, is in Settings-Port (Room name)-Port (under Product)-Disable WiFi.  This keeps the Sonos device from broadcasting SonosNet.

Of course if you believe the label that says "disable wifi" you will find you have issues with things that require the internal radio be active.

Not an issue on the Port but if you want surrounds or a Sub in that Room you'll need the radio active.

​@Stanley_4:

 Got a question…. I have a Sonos Arc.  At this time it is connected to the network wirelessly.  If I wired the Arc it would then broadcast the 2.4 SonosNet.  So your saying if I checked Disable WiFi on the Arc that I would loose both the 2.4 SonosNet & the proprietary 5 for bonded speakers?

It’s been covered extensively, the ‘Disable WiFi’ is mislabeled. It in fact disables all radio emissions from the device, not only what we call SonosNet, but also any 5Ghz transmissions to the surrounds. They should continue to work, if they’re also wired to your router. But if they aren’t wired, they should stop working.

I’d think this is fairly easy to test. 

I tried the wired Arc, with the wifi/radio disabled and Ethernet to a Sub and surrounds a long time back and my network didn't do a great job of getting good the music to them. Ethernet to any of my Sonos is long gone and my home wifi and the 5 gHz Sonosnet are doing a perfect job.

The 2.4 gHz Sonosnet is not available on newer Sonos making things easier.
