Cannot connect WD Live TV media player to Sky Sagem router

I have the latest firmware for my media player, and I have attached a network cable direct from the router to the player, but the light on the router (for the port) just flashes every 2/3 seconds. When I try to connect automatically in the network settings it says it cannot connect. If I enter the IP address ect manually it says set up complete but when I  try to test the connection it wont find the IP address and when I go back to the network settings it has changed all the settings back to 0.

Can anyone help.

Try pressing the reset button, if that doesn’t work you can setup a static IP address.
