I'm looking to buy a Steam Link to stream my games to a TV in the lounge. My WiFi signal in the lounge isn't great and besides Valve recommend to connect via Ethernet so I was wondering is it possible without drilling holes and running cables through ceilings to do this with a power line adapter so I can run the Ethernet cable from the power line adapter (which will be plugged in besides the TV) to the Steam Link? I'm new to this technology so I don't really understand how it works entirely.
