Welcome to the community. In your diagnostic report I see that your speakers are occasionally losing connection to your wireless network. This is likely due to wireless interference from nearby networks running on the same wireless channel as your Orbi. It looks like you have a couple other networks in your home. The Sonos system can connect to a mesh network system like your Orbi network, but only if all of the access points are putting out the same wireless network name, wireless channel, and password. Try moving your Orbi network over to channel 11, and leave the other networks on their current channel. This should reduce interference between them and may help with your Sonos system.
Another option is to switch your Sonos system over to the Boost setup. By wiring in any one of your Sonos units with an ethernet cable to your Orbi hub, the Sonos system will switch to its own mesh network. You can change the wireless channel of the Sonos mesh to reduce interference from other nearby networks.
