Try unplugging the Family Room speakers from power for a couple of minutes and reboot your router and phone.

Are you able to connect any of your Sonos devices (not a Sub or surround speaker) directly to your router with an ethernet cable? This will create SonosNet, a dedicated mesh network for your Sonos speakers that can oftentimes improve their network performance.

I have the “Beam” in the Family room connected to the TV.
