One speaker from stereo pair stops working

Only Sonos employees can see the diagnostics. You could either call in, or try their support on Twitter or Facebook, or wait here. I would think that on a Tuesday, someone here in the forums would be around fairly soon, I expect Mondays are fairly busy from catching up on the weekend posts.

Can anyone let me know what my diagnostics report above said please??

Hi MattyBur,

In your diagnostic report I see that your stereo paired speakers are losing connection to your wireless network frequently. This may be due to range or wireless interference. There are quite a few networks nearby, so it may help to try changing your network's wireless channel to 1. Also, take a look around your stereo pair for any third party electronics which could cause interference, try moving anything you find away from your speakers and see if that helps.

Hello, thanks for your reply.

So, since then, I've connected both of the stereo pair (Lounge 2) speakers to the router via Ethernet, and disabled WiFi on them, but the problem is still occurring, both when on TV and when playing music.

As before, if I ungroup the rooms and regroup them, the right speaker will come on again, but it will drop off again next time.

I don't understand why this would be, when they're on a wired connection now and not using WiFi.

My router is a Hyperoptic and is fine for everything else.

New diagnosics number is while music is playing and the right speaker isn't working: 361333548

Could you let me know what's going on here please? Thanks, M

Won't hurt anything to set static/reserved IP addresses for your Sonos devices from your router's DHCP page, power down Sonos, reboot router, power up a wired Sonos and then your other Sonos stuff at minute intervals. Might help, might not, won't hurt.

Thanks for trying that. I see some interference on the 5 ghz spectrum which would only affect your rear speakers and Sub. Take a look around those for any electronics which could be interfering with the 5 ghz signal.

For your stereo pair, I see that the errors are with the connection to your Mac. Is your Mac going to sleep while you are playing from it? Please check the computer's sleep settings in the energy settings page of the Mac's system preferences. Make sure it is set to never go to sleep and to not put the hard drive to sleep.

If these steps don't help, it would be best to continue troubleshooting this live with our phone team. You can find our phone number and hours here.

Thanks for the reply. I don't think it's anything to do with my Mac as this problem occurs whatever the audio source, including Amazon Music, or TV, which has nothing to do with my Mac.

There's no problem with the sub or the rear speakers so wifi interference is not an issue, and the problem is only ever with the right speaker of the stereo-pair, both of which are now hard-wired, so I can't understand why that would be.

Even when I swapped those two speakers round and re-paired them, the problem still occurs with whatever speaker is designated as the Right speaker, so it's not a fault with the unit itself.

I've tried tackling this with Sonos via Twitter but they just keep asking me endless irrelevant questions about my router and wi-fi extenders etc so I don't think I'm going to get very far there....

In this case it would be best to have our phone team take a deeper look. They have more tools available than our online teams. Please give us a call, our phone number can be found here.

I don’t understand why you chose WiFi channel 6 either? Did you do a scan of the channels in use nearby using wifiinfoview (or similar software) to discover the least-used channel for your router? Also you will need to set your SonosNet channel to a completely different channel to the one in use by your router... Set that SonosNet channel at least 5 channels apart from your routers WiFi channel to avoid overlap of the signal.. it’s not just all simply about wiring your speakers, as the signal still needs to get through uninterrupted.

I believe it is the left speaker that does all the lifting, and passes right channel only to the stereo paired partner, keeping them in sycn etc. So check what electronics are between the two. Mine are on bedside cabinets with a wireless phone and clock radio between them. This is the only problem I ever have, and then it's only every 6months...so far....I wonder if updates kicks it off....

Thanks Paul. Would that happen though if both speakers are ethernet-wired to the router though? They are, so there's no wifi communication between the two speakers, so I don't understand why the right speaker would lose its connection...?
