Unplug all Sonos devices from power.

Reboot your router.

Wait threeminutes, then plug the Sonos devices back in to power. 

Hi!
But the problem remains that music drops out every minute or two.
This is a hardwired system so wifi interference shouldn’t be the problem.
And I cannot reboot the system every time I change radio station...

Any Sonos people that could bring some light on this?

The procedure I listed above doesn’t really address WiFi interference, it is for network issues, which can occur either when connected via WiFi, or wired. 
 

If you’re interested in engaging directly with folks from Sonos,  I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

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.
