Hi Sonos folks. I wanted to share an issue that I hadn’t yet seen info about here. I lost connection to my existing system and could not fully reconnect all speakers and other components by rebooting router, factory resetting speakers, etc. I did an online chat with a Sonos support agent who was very friendly and responded quickly. He instructed me to contact my ISP (Verizon) to have them enable “bridge mode” on my router to fix Wi-Fi network conflict issues between my Verizon router and my Google mesh network. I asked if my recently connecting a mesh point via an Ethernet cable might be the problem. The agent said no. As a test I disconnected the Ethernet cable from that mesh point and my Sonos connection issues were resolved after I rebooted my router.
Bridge mode is a common issue for many. But it wasn’t the issue for me. Connecting a mesh point via an Ethernet cable is what blew things up.
I hope this helps others. Peace.
