Hi. I own Sonos beam + 2x SL One as surround sound system connected to TV (thru hdmi). All speakers are connected to internet thru wifi (router has channel 11, sonosNet also 11).
Randomly during day, while watching movies or youtube videos (philips android TV), one or both ( i cannot say just from listening) SL speakers delays few ms themselves and we can notice annoying echo there.
From my investigation a solution for me is to go to Sonos app → Settings → Surround Audio - switch Off and On again. And this helps.
I sent diagnostics logs today (nr. 1146608852 , nr. 2094903246 ).
Can somebody investigate this and help me what can cause this issues? Sometimes happen 4-5x per day.
I have all my 3 devices in same room (grouped to one room virtually as well).

Hi @matmatmat
Welcome to the Sonos Community!
Your Beam is continuously having to change the 5GHz WiFi channel it’s using to communicate with the surround speakers. This is most likely the cause of the issue you experience, and is likely, in turn, to be caused by a nearby device also transmitting on 5GHz - most likely your router or a WiFi access point/extender.
Judging by the signal strength your Beam receives from the router, I’m guessing they’re close to each other - if this is the case, please separate them by as much distance as is practical, and by no less than 1 metre (3 feet).
If relocating your router didn’t help, then I recommend you tell your router to not switch 5GHz channels automatically, and instead stay on one specified channel. Your Beam will then choose another.
I hope this helps.

Well. More devices are in room. But what can interference with them? Cannot this be investigate from my diagnostics log? I have no idea what can cause this problem
Unbond the One SLs from the Beam and unplug all of them from power for a couple of minutes. Reboot your router. Plug them back in and bond the One SLs to the Beam as surrounds again.
