I have a Comcast wifi/router connected to Comcast broadband. I have 2 PCs connected to it. Both connect directly via CAT5. In my garage, I have a NAS unit connected to a switch that goes through another switch, then to the router / LAN. For clarity, DESKPC cannot see the NAS, but TVPC does. Both PCs run the same Windows 7 Home Premium. I need DESKPC to see the NAS.
