I moved your post into support as there responses should be quicker there. It would help if you listed your PC, Network (router,switches etc) for support to help. Some routers are a bit roon peculiar, as a for example.
Main router is a Netgear Nighthawk R8500. The PC that houses Roon is connected to a Netgear Nighthawk R7500, which itself is connected to the main R8500 by cat5.
CenturyLink fiber provides the internet connection to the R8500.
As a test, I’m hoping we can temporarily try a simplified network setup so we can see if this yields any changes. If you connect the Core and one of the Sonos devices directly to the primary router (R8500) via Ethernet, is there any change?
The Sonos devices are currently connected via WiFi, correct?
Thanks for the reply, Dylan. Sorry for the delay, I’ve been travelling for the past week or so.
Update: I bought a fanless PC (Win10 Pro, SSD, etc…) to use as my Roon controller. This makes it easier to plug directly in to the router. I’ve taken one Sonos Play1 speaker and plugged it in to the same router. They are literally beside each other. I disabled WiFi on that Sonos speaker. (FYI, the rest of my Sonos set up is mostly WiFi, but there are 5 or so speakers plugged in via ethernet. I also have one boost and two bridges).
Roon does not see this Sonos speaker. It only sees AirPlay devices (2 Apple TVs, one Sonos ONE).
On this new pc I have the Windows Firewall turned off for all 3 zones. In Windows Explorer under Network you can see all the Sonos equipment.
I’m pretty advanced with PCs and networking, but this has me baffled.
This new PC is being used as my Core. It has the Windows Firewall completely disabled. It is plugged into the router right beside the Play:1 speaker, which has WiFi disabled.
OK, I did the steps you outlined above. I also unplugged one bridge and the boost. I did a factory reset on two Play:1’s that weren’t behaving inside the Sonos app, and now Roon sees the Sonos system!
