I have a Play 1 and a Play 5. Some days after Uverse did a software upgrade, I lost WiFi connectivity to the Play 1. A day later, Uverse did another software update and I lost connectivity to the Play 5. Both work when connected via Ethernet cable. When I pull up the desktop app, I get a ‘cannot find Sonos’ message. I was on the phone for over two hours with tech support, and the problem could not be solved. I deleted the Sonos 2 app and reinstalled Sonos 1, but that didn’t make any difference either.
Almost certainly, the problem has to do with Sonos WiFi communication with the Uverse router. PW and router info are all correct in the app, which I checked and re-entered while hard wired.
Anybody have any suggestions?
