Hi @Tyler K.
Thanks for reaching out and welcome to the community!
I appreciate your detailed post outlining the issue and especially your effort in submitting the diagnostic, let me help and try to figure this out.
Upon checking on the diagnostic report, the system detected errors and one of those is the home channel mismatch, wherein your system is on a mixed-mode (SonosNet and wireless). Supposedly, when one of your Sonos products is directly connected to the router via ethernet cable, it will create a dedicated network for Sonos which is called SonosNet. I see that the Boost is wired but there are speakers still connected on your Wi-Fi and not on the SonosNet.
I suggest following the steps below to try and get the error corrected:
- Try to change the SonosNet channel to the same home channel as the station mode (wirelessly connected) devices:
- Open the Sonos app and go to Settings > System > Network > SonosNet Channel
- (Your SonosNet system's home channel is 6 and the Station Mode system's home channel is 11, please change the SonosNet channel to 11)
- Wait a couple of minutes for the devices to switch from Station Mode to SonosNet.
- They should now have the same Home Channel.
Let us know how it goes and if you have any questions feel free to reach out, we’re always here to help.
