We have a Samsung un55mu8000 telly. It's connected to our wireless network (5GHz). We have a lot of video content on a Western Digital EX4100 NAS that is connected to the wireless router via an ethernet cable. We haven't figured out how connect to the NAS with the UN55 to view the video content. A saw a thread from 2015 that said you had top use an HDMI cable, which is not viable unless we punch a hole in wall and floor. We'd appreciate any help in achieving this connection.
