I have enjoyed my Sonos Connect box for more than 6 years. No issues in the past, until a few days ago. Without any obvious cause, the Sonos Connect became unresponsive and all attempts to recover it have failed. I have tried restarting the controllers/apps, switching ports on the router, restart of the router/internet, power cycling, etc. Attempts to use various button combinations on the front of the box to reset to factory settings have also failed. The only thing that the box does now is to blink constantly from the 4 ethernet port lights on the back as soon as the power supply is connected.
What does the non-stop blinking of the 4 Ethernet port lights mean? It does this with and without ethernet cables plugged in.
Is there any hope to recover the Connect box, or is this thing fried?
Does it have to do with a recent firmware/software upgrade performed in the background?
