SONOS not working with new C7800

[hopesprings]

I use a SONOS Playbase speaker for TV and music via the SONOS app.  Previously, worked fine via wifi for TV and music via the SONOS app.  I got the TV sound to work after akward Ethernet cable connetion of Playbase and the Netgear C7800, but no music available via SONOS app.  After 1.5h on phone with SONOS, they said the problem was with Netgear.  I'm not a techie and have no idea what to do.  Firmware is: V3.01.38. (I've only have had the C7800 for a few days).

Does anyone have experience with SONOS compatibility (or lack of same) with Netgear wifi modems?

I don’t know what to tell you . I’ve got the same router/modem a few weeks ago and it continues to drop connection. I have called both NETGEAR and my ISP but neither one is helping . NETGEAR doesn’t seem to want to fix the issue .
