Hi - I had Comcast as my wifi with my Sonos and had no issues. When I added eero with three nodes, while keeping my Comcast router, my sonos playbar would no longer connect. I direct connected the playbar to eero with an ethernet cable, opened the Sonos app and forgot my wifi system > network > manage network (even though it has the same name and PW), and went through the process to “fix the connection”. I tried to connect to the wifi once and it failed. So I tried again and unplugged the Ethernet cable while it was connecting. Fixed all my issues and works great (without resetting a bunch of settings). Thought I’d share if it helps!
