Sonos Matrix Bunches of Red

17 replies
1611 views

I have 30 Sonos components hooked up in this house. Two Playbars, Five Subs, One new Amp, Two Play 3, the rest mainly Sono Ones G1 with one Sono One G2, and a handful of Play 1s. Two boosts.

Main problem is when I switch from Pandora to Apple Music. The devices cut in and out for one to two minutes. Also I’ve noticed that on my downstairs Playbar surround sound when playing music it gets a half second lag after a few songs. This is the only room that has ever played out of sync. Only way to correct is by powering off the room and then bringing it back into the fold.

I looked at my Sonos Matrix and so much of it is RED RED RED.

'Red’ is obviously WiFi interference that's either surrounding the device, or between connections.

Some things you can perhaps consider are...

Run your system on Sonosnet with one device wired to the main router.
Set the routers fixed 2.4 GHz non-overlapping WiFi channel to at least 5 channels away from the Sonosnet channel, ensuring both are least-used by neighbours.
Keep wireless devices at least 3 feet away from each other and objects that might interfere with signals.
Set all WiFi access points, hubs, extenders etc; to use the same SSID, credentials and channels as the main router.
Consider wiring Sonos devices to the local network where interference remains high after exhausting all other options.
Add all Sonos IP addresses to the main routers DHCP Reservation Table.
Ensure that the 2.4ghz WiFi credentials are not stored in the Sonos App network settings and if using the Sonos Move speaker consider using that connected to the 5ghz band.
Place other wireless network devices around the home onto the 5ghz band where it's practicable to do so.
Review the network WiFi channels in use from time to time in case neighbours alter their WiFi settings, which may then introduce interference.

I am running Sonosnet, Boost hooked to Router. Even tried Black Amp hooked to same router. No change.

Set the routers fixed 2.4 GHz non-overlapping WiFi channel to at least 5 channels away from the Sonosnet channel, ensuring both are least-used by neighbours.
I have a Eeros Pro mesh network. Eeros separates the bands extremely well. Neighbors are over 200 meters away. That is just property lines, so much further device to device.
Keep wireless devices at least 3 feet away from each other and objects that might interfere with signals.
Will try that, much easier said than done with so many Sonos and other devices
Set all WiFi access points, hubs, extenders etc; to use the same SSID, credentials and channels as the main router.
Set by Eeros
Consider wiring Sonos devices to the local network where interference remains high after exhausting all other options.
Tall order, will do for troubleshooting purposes. Sort of defeats purpose of Sonos wireless and SonosNet. :(
Add all Sonos IP addresses to the main routers DHCP Reservation Table.
Can do, will take some time, not sure why this would make a difference when using SonosNet
Ensure that the 2.4ghz WiFi credentials are not stored in the Sonos App network settings and if using the Sonos Move speaker consider using that connected to the 5ghz band.
No Sonos Move
Place other wireless network devices around the home onto the 5ghz band where it's practicable to do so.
Eeros and devices generally will do this automatically

What happens if you switch to another WiFi channel, 1, 6 or 11 and check the Matrix again?

You could submit a diagnostic and contact Sonos Support with the number it gives you to get them to look under the hood. We users can’t see that data.

The static/reserved IP tweak solves a lot of problems at reboot and update time so it is well worth doing. The larger the system the more likely it will avoid a future issue. It should only take a few minutes in your router’s DHCP settings, take an extra moment and give each Sonos a meaningful DNS name while you are there.

Pick a slow day and start unplugging stuff, not just stuff that has a radio in it, and see if you find one or more devices causing much of your unwanted RED color.

Things like WiFi cameras, baby monitors and such are prime suspects so maybe start with them.

Suspect everything! My offending device has no radio so I ignored it and wasted hours poking at devices that were not a problem. The device was a Western Digital Ethernet connected external hard disk. No radio, just crap, noisy electronics.

Wifi channel on routers and access points? I believe the Eeros do that automatically.

I have seen other folks do that. Will be most happy to.

I’m sure my situation is something like that. Some of the devices in red are not near anything that I think would cause interference.

Routers auto switching WiFi channels does not mix well with Sonos that uses a fixed channel.

Switching the Sonos channel will allow you to see if the red is coming from a device on a single channel or is broadband in nature. Knowing that you can likely narrow your search for problem devices a bit.

Initially when I posted this, I might have not understood how to read the matrix. I’m still pretty clueless, lol. What had me alarmed at first was all the red along column one. Looking at the actual rows and columns in the matrix every thing is a mix of mainly GREEN, some YELLOW and sometimes one or two ORANGE. Am I safe to assume that even though the column header shows mainly RED, some Orange and a few GREENS, that I am getting good signal between the two devices that converge in the matrix.

Signal strengths are okay/good. Everywhere is being slammed with interference though. It’s sufficiently widespread that something very noisy must be active. It’s likely to be a non-WiFi actor in the 2.4GHz band. Proprietary wireless or high strength Bluetooth perhaps.

Did you try using the three clear channels 1, 6 and 11 to see if they made any difference to the red cells?

Thank you for your reply, I did and seem to make minimal difference.
