Try hardwiring it to your router with an Ethernet cable.  If there is any interference a wired connection shot resolve it.

Then check for updates.

Thanks, actually forgot to mention I have it wired in already and on my router I can see it says SonosZP, model: Zonepkayer Zp100… but it is in fact a play 5 gen 2 model

When is the last time you updated it? 

I’m listening to two Sonos PLAY:5 gen 2s as I type this. They happen to be grouped with a pair of PLAY:1s right now. 

I could see if it’s been a while since it was updated, the firmware on it might possibly be too old to be caught by the automated process, but it would likely need to be quite a while since it was last updated (likely years, not months). 

I would recommend that you submit a system diagnostic and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here, they get sensitive about GDPR.

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 Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Thanks for the pointers…it has been in fact probably several years since the firmware was updated…I’ll do as you suggest and see if the Sonos support can help, thanks for your help/suggestions
