WD Live cant find network

I have a router upstairs.  Wd Tv Live downstairs.  I have inputed all the IP info manually, done auto setup, plugged directly into router, and it never works…  When I plugged the player into the router it prompted me to update the firmware; I did.

I can plug a Hard drive into it and play movies perfectly; but nothing via the router or my network.  At one point I could view a folder on my network containing movies;  but nothing was in the folder according to WD TV Live ( on my computer plenty of files)

Anybody have any suggestions or know why my WD live wont sync to my home network?

Follow the link below for the steps to share a folder so the WD TV can see it.
