• If you can stream music to your soundbar it’s still on the network
• In this particular instance your soundbar and/or sub & surrounds have not lost connection with your network.

Trouble Shooting

• The trouble shooting should begin at the source which is the HDMI or optical connections between your TV and the soundbar
