Multiple Sonos Ports in separate installations. One or multiple Ports will drop its connection ( was selected in the app, but then drops ). The Ports are all hardwired. Go back into the app select again, it will play for a few minutes and then drop again. This happens across multiple Ports at multiple locations. It is not location specific. Reboots of the switch, and modem have no effect on the behavior.
Anyone else seeing similar behavior over a hardwired Ethernet network?
Have the Sonos devices been powered down/unplugged while the reboot of the router (not the switch, nor the modem, the router is the device that controls DHCP, most often)?
It sounds a lot like duplicate IP addresses, but that’s a guess. You might find out more if you were to 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 network and Sonos system.
Setting static/reserved IP addresses for your Sonos followed by powering them down. rebooting the router and powering them back up should remove any IP address issues.
Even if it doesn’t fix anything it is one possibility off the list of potential problems.
