Hi, I live in an old house with thick walls, so there isnt much wires running through them. My house runs on wifi, and with the thick walls, the speeds are quite slow... The router is hooked up via a coax cable, and the computer next to it gets very high speeds because it is wired to it. I have a set top box in another room hooked up with coax too, and I was wondering if there is a way I could connect the PC which is across the room via ethernet? Thanks c:
