When I attempt to connect my Computer to my Xbox 360 using Windows Media Center I am unable to. I get a message that says "Cannot Set Up Extender" and a link to a very vague Microsoft help page.
I have temporarily disabled the firewall on my PC. (Windows Firewall)
I am using a DLink DIR-601 N-150 Wireless router with UPnP and Multicast enabled.
My PC is currently running Windows 7 (rev. 7600)
The Xbox 360 software is current (Last update issued 1-19-2011)
