I have 22 various Sonos speakers through my home. I also have a 1 Gbps Internet high speed connection with a Asus AC-5300 high end router.
When all 22 speakeers are plugged in and operating my speedtest performance is about 150 mbps. Today, I shut off 8 of the Sonos speakers. I then did a speedtest and consistently got close to 500 mbps. I again re-plugged in the Sonos speakers and performance dropped again to 150 mbps.
Can someone tell me why Sonos speakers are so chatty that they are killing my network?
