I have a Play 5 and a Play 1 which have worked flawlessly in my home for nearly two years, with controllers in an iMac, a MacBook Pro, two iPads, and two iPhones. Always works. A couple of days ago I upgraded to 9.3. Now each of these controllers may work or may not, and if not now maybe later. What has happened? None of Sonos' recommended troubleshooting steps seem to fit this situation. WiFi is strong throughout my home with an Eero system. And if one of the six controllers isn't working, one of the others will. Until later when the situation may reverse. Does anyone have an explanation for this, and a suggestion for what I should do next?

If it happened immediately after a software update, it's most likely an issue with duplicate IP addresses, which is exposed by the way that Sonos soft boots each speaker during the process. If your Eero has lost its place in the DHCP table, it could hand out duplicates. I'd recommend a refresh of your wifi environment.
