Have just purchased a Sonos Sound bar. We have Virgin Media Superhub,TIVO box and Panasonic Smart TV. Panasonic is connected to Superhub Router with ethernet cable to make 'smart' connection. Soundbar is connected to TV via digital line supplied. There are 2 spare ethernet ports in Soundbar, 1 in TV but none in Superhub. Do we have the correct wired set up?
