Sonos One interference causing system-wide audio dropouts?

Well unfortunately, I had about 3 good days of uninterrupted (dropout free) audio, but just encountered some bad interference last night. The rear Play1 surrounds and Sub were continuously dropping out for 5s each time, about every 20 seconds. It occurred while I had the TV line-in audio coming through the Playbar, and was also streaming some content on my iPad in the same room (it's connected to my 5GHz wireless channel). Interestingly, the dropouts completely stopped as soon as I closed my iPad (clearly implying it's likely a 5GHz interference issue). I hadn't recently changed any of my wifi or Sonos settings that had been working for the past few days (since splitting my wifi into dedicated 2.4GHz and 5GHz channels).

Based on the previous info about the rear surrounds and sub communicating via 5GHz, this makes me wonder if SonosNet (boost mode via ethernet wired Playbar) is switching 5Ghz channels intermittently? Or my router auto-switched it's 5GHz channel to a conflicting one with Sonos. I know in advanced settings we can set the Sonos 2.4GHz channel. However, I'm curious if Sonos always run on certain 5GHz channels, ie. it would be advisable to set my router to a static 5GHz channel outside of the Sonos range in order to minimize interference?

I can submit an additional diagnostic report the next time this behaviour happens. But I suspect it will just show the same as the last ones (eg. "interference" from other devices on my 5GHz channel). Thanks in advance for the additional help Sonos team!

Here is a diagnostic corresponding to the most recent surrounds/sub audio dropouts. Diagnostic # 1690248755. It seems to only occur when laptops/phones are being using in the same room, which makes sense if everything is competing on the 5GHz channels. Sonos team, can you advise on my earlier question about whether Sonos rear surrounds/sub in Boost mode use certain 5GHz channels? In other words, would it be preferable to set my router to use 5GHz channels outside of that Sonos range? Thanks again - hoping to get this worked out soon!

Hey there, el_matt0. Are you still running into problems in the 5GHz band? Sonos will always look for the least crowded 5GHz channel. If you "lock" your router to a particular 5GHz channel, Sonos should steer clear of the interference. Typically, we want to lock it to a lower channel such as 36 or 44. Test this and let us know how it works out.

Thanks!

Hey Keith. It's been in general a lot better, but still definitely not perfect sadly. We are still getting about 1 or 2 brief dropouts every hour or so if listening continuously (or using the TV line in) on our living room surround setup. The rear surrounds/sub audio dropouts always seem to coincide with someone checking text messages or using their phone on the 5GHz band in the same room (which in theory is "between the line of sight" of the ethernet wired Playbar and the rear surrounds).

I will try setting my router to the lower 5GHz channels to see if that works. Generally it seems to prefer either 149 or 165 when set to auto, so I had currently left it locked in at 149 but was still having the above issues.

I have been experiencing very similar issues and seem to be at the same point, can you please let me know if changing the 5ghz channel worked. My router is set to channel 161 80mhz.
Cheers

Sorry just re read your post and see that changing the channel did not help, it has been six months can you please post an update i would be very interested to know if you have resolved this problem
Cheers
