I am trying to connect a soundbar to a Sharp smart tv. There is no wifi where the tv and soundbar are located. (My boyfriend's parents are both 80 and are not interested.) Do I need wifi for this soundbar to work? (It does have the wireless subwoofer but I am told that functionality is in the unit already). Is there anyway I can "wire up" the unit to the TV if I do need wifi? And if not, does anyone know of a soundbar that can work without wifi so I can switch it out for them ? Any help would be appreciated.
