When I first try out Wi-fi Media Connect last week, it did not worked. This morning, it did work. But, I had to log out of it, and then when I did tried it again later in the day, it did not work anymore. I get an connection error code. The model of the tv is 55PFL4706/F6. The PC is Windows 7, Nvida, Intel Pentium. The wireless router is Netgear. Can someone please tell me how to get it working again?
