Troubleshooting: Wired Sonos causes disconnects for all wired devices in network

Hello,

I have a network setup, where I have a Zyxel modem connected to the ISP, with 2 WiFi APs connected in LAN ports, and an ethernet switch connected to a LAN port directly in the modem as well. The ethernet switch connects the rest of the wired devices in the house.

When I wire my Sonos Beam, it creates the SonosNet mesh and the rest of the speakers connects to this, everything looks fine. After the Sonos has been connected and everything is set up, random disconnects starts happening on my network. Every device connected through the switch loses connectivity to the modem. The devices connected through the switch still has connectivity between them, but the modem seems to have dropped off the network. The WiFi APs are still online with connection to the internet though, so I know the modem is still online. And the switch is working since the devices connected can still ping other devices on the IP they had before the modem dropped.

When I remove the ethernet cable from the Sonos Beam, the network drops stops happening.

Without the SonosNet, I’m having problems pairing devices when they are not connected to the same AP. If I’m in one end of the house, I will see the Sonos devices nearest me. When I walk the the other end they drop out and the others appear. Pairing between them is almost impossible. This problem disappears when using SonosNet, but then the network disconnects happens.

Any help would be appreciated.

Hi @miklen

I can see a little of what I was expecting to see - multicast flooding on the Beam’s ethernet connection - but not as much as I was expecting to see, given your report of the issue. The flooding is spaced exactly 10 minutes apart, but I cannot tell where they are coming from - only that the packets are arriving at the Beam and are not intended for Sonos.

I also see a somewhat high transmission failure from the Beam to Badeværelse, so if limited bandwidth was taken up by re-transmission of these packets, that could explain the issue, but only if the switch were 100Mbit max instead of 1Gbit. If this issue reoccurs, you could try switching off Badeværelse - if that immediately clears the issue, then the answer will be to reduce interference near that unit (which you should try to do anyway, but switching it off is a handy test to confirm the issue before resolving it).

I hope this helps.

@Corry P thanks for the info. I haven’t had any fallouts since the one I reported. I later found out that my ISP had issues that night as well, so that may somehow be a factor as well (though the WiFi was still working as usual). I haven’t had any other fallouts since. If it happens again I’ll try disconnecting the speaker you mentioned and see if that helps.
