Today's systems require US to learn to integrate them. It could be as simple as updating the router or replacing the router but many of today's buyers are not going to learn all about networking. So it's something but given only this to work with I suggest you forget wifi and get some powerline network solution.
Why is it that my sony media player works ok on a wireless connection and my lgtv smart tv with st600 upgrader did work and message displayed network is not connected and do I want to reset previous settings and when i select reset it, I lose my connection with sony media player? Can my wireless router connect both without disrupting both ?
