|I've yet to play with anything like this myself so I don't know how the TV connects or sets up but if it were me, I'd try to look at the network settings for the TV to ensure it's getting proper TCP/IP information (you can compare against a computer in your LAN that is working properly).|
It sounds to me like your TV isn't getting the correct TCP/IP information.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
