I am getting the same thing.  Using a D=LINK DIR-655.  I get activity lights on the port on the router, and the light on the router corresponding to the blade lights up, but nothing after that.  I am using a single blade and am using an adapted Molex splitter as described at the beggining of this topic.

 I contacted the guy on ebay that I bought it from and he said to check the range from 192.168.1.200 - 220 and nothing there either.

 I am connected to the router with a 50' cable and will try a different, closer cable later as well as reset my router.
