Can't Disable Wifi from Ethernet Connected S1 Device

It sounds like you have understood the position very well, and also reached the right conclusion about what NOT to do!

This stuff from the ISP about bandwidth being allocated sounds a bit implausible to me, but i don’t know enough to really challenge it.

The reason you didn’t have a “Manage Networks” screen is because you don’t have any WiFi networks added to Sonos - which was why you were seeing the behaviour you were seeing, and which you now understand.

Now we know where we are, I would now (after all) like to know which wireless channel your router is using.  If it is set to anything other than 1 or 11, please set it to 1 or 11.  Your problem may be caused more by wireless interference than “bandwidth allocation”.

Proteus,

When using SonosNet the only part of the “blizzard” that I described above that’s important is the traffic that ends up going out to the WAN (Wide Area Network -- the Internet). There will be minimal WiFi traffic to the SONOS controllers only when they are awake. Traffic between SONOS players will be handled by SonosNet.

I had the ISP reconfigure the WiFi so it uses only channel 1 and channel 11, never channel 6. The ISP technician thought WiFi interference may be the source of my troubles, and this should fix that. They also asked me whether I wanted to configure the ethernet connection to Sonos as 2.4GHz or 5.0GHz. I said 2.4GHz, because reading the Sonos documentation I understood that’s what Sonos supports. However, if you advise me to change to 5.0, this would be easy to do.

I guess the thing to do now is try it out and see if the problem is resolved. Buzz, I do follow you about the blizzard being on SonosNet. I hope I’ve now got it set up so there’s no interference with that blizzard.

I will let you know, either way, how this works out. Many thanks for all your support.

Well, I don’t have happy results to report. I am still getting occasional drop-outs. Sometimes there’s silence for a second or so and then it picks up where it was. Sometimes something strange happens - it goes silent, and then skips one track forward (always forward, always to the next track). What might be causing this behavior with my current configuration? How to diagnose and cure?

When playing from an external service the typical response to a large communication issue is “I give up on this track” and the next track in the play sequence will be attempted. A short communication issue will result in a mute. It’s a judgement call by the player as to the severity of the communication issue. If it seems like a brief issue, the player will mute. At times the player will bungle through, assuming each of a long string of issues is minor, resulting in a cascade of “brief” mutes that is effectively a perpetual mute for the listener.

Submitting diagnostics and working through SONOS support is your best plan, We don’t have access to the diagnostic data. Local and remote issues will leave characteristic tracks in the diagnostics. Submit within 10 minutes of an issue because fine diagnostic data will eventually start to scroll out of view.

This makes perfect sense, thank you. I just encountered another moderately long drop-out and submitted diagnostics right away. In case someone on this thread is able to read the diagnostic, the confirmation number is 1611198388. I’ll try to connect to Sonos support with this.

Unfortunately, those of us outside Sonos don’t have the ability to read the diagnostic data, probably due to an amount of PID in them. 

This is completely meaningless and increases my suspicion that you are being fed a lot of nonsense by the ISP.  Ethernet cannot be 2.4GHz or 5GHz.  It isn’t wireless, it’s wired!!
