Hi @Giftedmike, Thank you for reaching out, and welcome to the community. Sorry to hear about this issue on your Sonos system and thanks for submitting a diagnostic report of your system. Upon checking, It shows incomplete diagnostics. If you can temporarily wire one Sonos speaker to the main mesh router and submit a diagnostic report for us to check what could be causing the issue. 

Let us know what you have in mind with the advice above.

Hi Simon

Thank you for the fast response. I’ve connected one Sonos and to be fair it has fixed the issue.

my new diagnostic number is 

300383727

i think the system isn’t playing well with my net gear nighthawk network. It worked fine with my Apple mesh network

Hi @Giftedmike, thanks for the update and for sending a diagnostic report of your Sonos system, upon checking the report, It shows that there is a lot of Wireless interference and low bandwidth of connections. Kindly check this link about reducing wireless interference and Music service stops or skips for some troubleshooting steps for this issue. You may also check if there are any devices or objects that may cause the wireless interference or if the speakers are far from the router since it detects low bandwidth of connections. 

Let us know what you have in mind with the advice above.
