Persistent playback issues

Pictures of boost below. The ethernet socket it is plugged into was fitted and runs straight to switch

The room is below the study, and is also adjacent to utility room and the living room with no doors, it's all open plan. The piano room is just off the dining room too (it's an odd shaped house) and is no more than 15ft away

Hi @Goteamtom 

That’s not a WiFi acoustic guitar is it? 

In terms of interference, it looks fine. What could be a problem is the likely increase of mass in that corner, due to extra joists (depending on the materials used, of course). Do you have another spot, ideally central to your Sonos devices, where you could test the Boost, while keeping it wired?

unfortunately this is its third location! i’ve tried it the other side of the dining room, and upstairs in the study. the best performance has been in it’s current location. realistically the dining room or the study (almost directly above) is the most central spot in the house. when we first moved in it was in living room briefly and the garage but that proved completely fruitless 

Hi, apologies for the delay in replying. So I've finally plugged another sonos speaker into the switch, and the results are strange. Firstly, the flashing lights on the switch above the two sonos ethernet cables both are flashing slowly, with both the green and orange light flashing simultaneously. And then after a few mins sonos starts skipping songs in quick succession before dropping out completely. I then need to unplug the additional wired sonos units and reboot the switch, and then it's back to how it was!

Any ideas? I've googled, and it suggests it's a spanning issue? I've no idea..

Please help

Sorry, a diagnostics code 820712339 

Its getting to a point I don't use sonos anymore. I used to leave the radio on for my dogs when we're are out. But I don't remember the last time the radio played for more than 20 minutes before turning itself off. When. Playing music it'll randomly skip mid track and rlthen skip several tracks, finishing a 2 hour playlist in 20 mins..

Its steadily getting worse and I'm in the midst of doing up rooms in the rest of the house but am not adding speakers to them...which is the only reason I want sonos..

I know there is something sapping the Internet, but I can't work out what. And nothing else seems to have issue except sonos. 

Apparently bang and olufsen is (whilst a lot more expensive) have a more sturdier wireless set up. I am considering replacing, has anyone had much experience with B&O? Because whilst writing this post my sonos has skipped 3 songs!! 

Hi @Goteamtom 

A “spanning” issue will be relating to STP (Spanning Tree Protocol) which normally prevents data packets travelling in loops on the network and never reaching their destination. They eventually add up to so much traffic that there’s no bandwidth left for other traffic. I asked for some help on this one, and the reply was that the players are noticing a lot of changes to the STP routing and they are constantly having to reroute and re-advertise themselves.

We suspect the router is at fault and may need replaced. However, something worth trying (if not already tried) is to run your Sonos system without any ethernet connections at all - as you have a mesh WiFi, they have a good chance of connecting. Please ensure all your rooms are online in the app and go to Settings » System » Network » Wireless Setup to tell Sonos your WiFi credentials and when the app says to, please disconnect all ethernet connections to Sonos. You may as well unplug the Boost from power too.

Within about 2 minutes, all your rooms should be visible in the app.

If that doesn’t help, I can only recommend testing a replacement router - to be returned for a refund if it doesn’t fix everything.

I hope this helps.

Thanks, I'm willing to try anything! 

Unfortunately I'm clicking following the instructions but the app starts to check to ensure the app is up to date, then reports an error 1001. I've tried restarting, it keeps happening.. 

The app then wouldn't let me connect to anything. Eventually it just started working, but only some of the speakers made it to the connecting to WiFi. I had to press the button on the back of the beam twice for it to work, and 2-3 minute it suggested it'd take to transfer all speakers over took about 5..and only a few made the journey!

Hi @Goteamtom 

Update error 1001 is the app losing contact with a player during the update process, which makes sense with what’s going on. Repeated retries might get you there eventually.

Now that at least some of your players know the WiFi credentials, they will share it with players that don’t know them - once they are able to talk. Wiring back to ethernet to get all the rooms back, waiting a few minutes, then removing ethernet again will hopefully get the credentials distributed. Any rooms missing at that point are likely having trouble reaching a WiFi access point. Or, the flooding is getting worse without the IGMP switch in the loop, and some players just can’t get on to the network due to this.

I did find this little list:

Devices that generally cause multicast flooding on Sonos:

• IP Cameras
• Network Video Recorders
• IP TVs
• TV Set-top or Cable boxes
• Home Security & Control Systems
• Network Printers
• Misconfigured network devices
• Using switches or a router that do not support IGMP Snooping

Perhaps you can try turning some devices off, to see if things improve. If one device in particular seems to be the culprit, searching for it and multicast flooding may provide some answers.

I wish I had something I could point to and say “yes, this is proof that your router is faulty”, but I don’t. At this point though, I’m not sure what else to suggest (assuming the Orbi router’s firmware is up-to-date - definitely worth checking). As you have a Virgin router, I suppose you could try putting it back into router mode and the mesh into Bridge mode, but as I personally have a SuperHub 3 too (also in Modem mode), I would understand if you didn’t think this was worth the effort.
