I have 2 Sonos Connects running in my house which I always used in sync. For the last few weeks they have been acting extremely unstable, constantly disappearing from the app. Today one of them completely stopped appearing in the app. The white light in the front is pulsing (I say pulsing and not blinking because it never truly goes out, it pulses from dim to bright). The green and amber LEDs above the Ethernet ports are all blinking, and there is a static sound coming through the speakers in sync with the blinking Ethernet LEDs. Now that this unit is not connecting at all, the other Connect in my house appears to be working perfectly again.
I have tried factory resetting the non-working Connect, it does not seem to register at all that any buttons are being pressed, it just continues the behavior I describe indefinitely. Any ideas on how to fix it?
