Next time it regains connection, submit a system diagnostic within 10 minutes, and call Sonos Support to discuss it. They should be able, I’d think, to see if there’s a failure in the electronics, or just a simple IP address issue.

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your Sonos system and network.

If it turns out to be a simple IP address issue, caused by your router, then merely unplug the Sonos device from power, then reboot your router. Once the router has had time to reload, plug back in your Sonos.

Thank you.  I will.  But always seems to happen when I’m not at home so all I can do is talk my wife through the power cycle.

She could make a diagnostic after the power cycle: https://support.sonos.com/en-us/search?q=diagnostic

Perhaps you could create written instructions -- for emergency use.

Wonderful idea. But….again the problem happens at odd times. A working list of instructions might help.  I placed my Sonos devices on Allocated IPs, which I saw in posts about this problem five years ago.  Hoping it fixes the problem. 

I made the spouse a nice user manual for my old stereo setup, with pictures. I also labeled any cords she’d need to deal with.

With my Sonos I’m using a simple remote power switch, saving having to move stuff to get to the power connection.

Good idea. Thanks. Bruce
