How do I get the TV feed to work with WF-803M? I have internet, Xfinity. All lights on the adapters are lit (I have activated encryption) indicating full connection, but my Xfinity X1 service does not reach the TV. Splitters do not solve the problem. In fact, the one splitter setup that lets the TV signal through kills the internet connection. I connect to the internet through a Motorola M7550 Cable Modem/Router.
