I don't understand why this works, but it does!

Because the ethernet port on both the empeg-car and the Rio Receiver has some issues with certain autosensing 10/100 switches. There is some handshaking that goes on when you plug into a 10/100 switch that autosenses things like Duplex, Speed, and Crossover. Something about the ethernet port on those devices doesn't handle that handshaking well.

And of course the ethernet port on your router is really just a little cheap 10/100 switch.
