Can't set up device

Hello I am having a lot of difficulty setting up my WD TV live device.

I have the WDTV live plugged into my TV. My wireless router is in a separate room. My PC is upstairs. I have a devolo dLAN 200 AV plugged into the WDTV, and another plugged into my PC. The lights are on on both devices. When I try to create a wired network it can’t detect one, but it will detect my media library. However when I try to play any file on it it says ‘browse error. content not available,’ I am using firmware 1.07.18. I have tinkered with my windows 7 settings to allow sharing and have turned off passwords. I have tried resettting, and ahve not other devices to try it with. Any help would be greatly appreciated

How about any of the online services like youtube, can you access them? If you can follow the link below to view the steps to share a folder from your computer.
