My Sonos arc keeps dropping off from the WiFi and I get a message in the app saying "sonos arc can't connect to your WiFi system, do you want to fix this now?"
This happens daily and the only resolution is to power off and back on. I've tried everything to fix it, from moving items around to turning the 5ghz band off on the router. I've even had a replacement soundbar.
I previously had issues with the sub dropping out, so I disconnected my philips hue lights as I believe they were causing WiFi interference.
