Bought a sub to add to my playbar. It will not connect. It always comes up with an error saying: SUB setup error, make sure your sub and playbar are connected to power. They both are. I read some stuff here about similar issues and since I was running this through my wifi network, i purchased a BOOST. I went through the setup to add that in, and tried to add the sub again, no luck, same error. I have done just about everything i can think of, restarted everything, re-added everything, no luck. The sub and playbar are probably 15 feet from the wifi router, so it shouldnt be a distance issue, but i cant connect them directly to the router. What am i missing?
