Does anyone have any experience or ideas to run some Cat 6 ethernet from the gateway in my master bedroom downstairs to the PS4 in the living room? I would like it to be hidden but I am clueless. My master bedroom is not directly above the living room and pretty much opposite side of the house.
Have you looked into WiFi extenders? TPLink makes all sorts of network switches, extenders, wireless access points, etc. that might help you out here.
