This started happening about a year ago. I have a Sonos One wired to my router, and a Playbar and two more Sonos Ones (in separate rooms) connected on the SonosNet network. Everything works fine, until the router reboots due to a power outage or other reason. When the SonosNet network comes back up only the wired Sonos One and the Playbar are recognized. I have to unplug and plug back in the other two Sonos Ones for them to be recognized again.
Any ideas on what might be causing this? I’ve tried changing the wireless channel, resetting the speakers and swapping out the wired Sonos One. No luck with any of it.
Thanks in advance.

It’s really hard to tell from your description. It could be wifi interference from a non WiFi source, or even a source outside your home. I’m loathe to jump to duplicate IP addresses, since you mention it happens even after a power outage, which normally should clear that issue.
You mentioned changing the wireless channel, do you mean your router’s WiFi channel (which should not be auto set, but defined by you), or do you mean your SonosNet channel?
There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.
When you speak directly to the phone folks, there are more options available beyond just the diagnostic analysis.
