As the OP has it sorted I'm going to ask a similar question.
I have a TiVO box (replaced a V Box today) & V6 TiVo box Upstairs & A TiVo Box downstairs.
The 2 boxes upstairs are connected to the router (Asus RT-N66U) upstairs, but the one downstairs is not connected to the router.
I want to be able to stream stuff between boxes.
I had looked at powerline adapters, but I belive this won't work as they are on a different circuit.
I then thought would a wi-fi extender like the one in the link below work, by allowing me to plug a cat 6 cable between the TiVo and extender, I need a thru-port?
