cat5e with an rj45 at either end would be your best bet.
Maybe i should have told you my setup first.......
My modem is at the master socket in the front hall of the house and i run a cat5 cable up to the router which is upstairs. now the media player is downstairs in the living room and it is wireless.
I wanted to keep the media player wireless cause i didn't want another cat5 coming from the router
Because its alot more tidy that way. I also have a trendnet 300mbps wireless n usb adapter in the media player. So is it worth my while getting a new router or going with the full cat5 setup.
