Hi @DustyB13
Thanks for your post!
As @Airgetlam suggested, the cause of the problem is interference. I can see very high (higher than I’ve seen before) levels of interference near the Office speakers and Sub. My guess would be that they are too close to a router, a mesh WiFi access point, a printer, a laptop or even each other.
Please read our reducing wireless interference help page and look to keeping the speakers 1m from possible sources of interference. Please keep in mind anything that might be on the other side of a nearby wall. If there are no nearby devices, look to remove nearby metal or glass surfaces.
Incidentally, the Roam does not connect to SonosNet like your other Sonos devices - it will only connect to your WiFi. It’s currently on channel 6, whereas SonosNet and at least one access point are both on channel 11. Please check your Sonos app and only if you see all your rooms present change SonosNet to channel 1 - Settings » System » Network » Change SonosNet Channel » 1.
I hope this helps.
