In my quest to rid myself of shiny discs I've installed sage-tv on my recently built HTPC. I now have an HD-200 extender on the way, (should be here wed.)
My stupid question is this- There is only one (1) ethernet port on my pc. If I plug in the extender I can't connect to the internet for all that coolness. Do I need another port on the pc via a card or something? Is There a magic box I need? Two wires and one hole.

just can't wrap my head around this...
