Connecting the WD Live TV streaming player to the TV through LAN

I’ve a router and a switch, I want to share media contents from windows media player (windows 7) to the WD live. My network topology:  PC connected to the router > router connected to the switch > switch connected to WD Live > WD Live connected to TV. I am using Cisco router and switch, I’ve to use both of them for some reason. I tried assigning IP address and pinged from my PC to WD Live, no packet loss, but I can locate the device on my windows media player. Can someone please help me in this situation. What combination of IP address should be assigned to PC, Router, and WD Live. Any help would be highly appreciated.

Thank You.

What combination? They have to be in the same subnet and workgroup.

You may also confirm that the SMP and your computer are part of the same Workgroup.
