I have a Samsung BD-F5100 which I use to stream videos from my PC to a TV.

This was all working fine until I upgraded my modem/router from D-Link DSL-G604T to a TP-LINK TD-W8960N.

Now all I get when I try to play a video on the Samsung is either "Device Disconnected" or "Not Available".

The PC runs Windows 8.1 Pro X64.

Any help or info would be warmly welcomed.
