Sonos devices not in Windows Controller after wifi router change and Macafee Total Protection installation, Music Library won’t play

Before:   Three Sonos devices, Play 1, Play 3, and Connect: amp. Sonos Windows Controller installed on my desktop, Able to play music from Music Library, and life was good. Connect:Amp hardwired into Ethernet network, other two wireless.


Then: I installed Mcaffee Total Protection on desktop, and and changed my wireless router from Google Fiber provided wifi to a Google Mesh Wifi network. It took some doing, but I was able to get all three devices to come back up, streaming works fine.


The problem:   Windows App does NOT show the Sonos devices like before, trying to play from Music Library from my IPhone or Ipad returns “Server Cannot be Found”, and won’t play. I saw that Mac Total Protect can cause firewall problems, so I turned Firewall off, but no change. Looking at my Google Fiber network diagram, Sonos devices are there, but now grayed out, and designated “Disconnected”

For future readers, I recommend one major network change at a time. In the OPs case router change AND McAfee installation means the root cause is a lot harder.

However in this case it is probably easy: new WiFi network on PC I assume, needs to be marked as Private to Windows, it will default to Public which will block all Sonos networking.

Thanks for your reply. You’re right, I wasnt thinking clearly when I did both things.


I’ll try your suggestion; for now, though I have turned off the firewall in an attempt to resolve. Still working with it.
