I am preparing to build a PC and as I was planning, I originally intended to remove my router and modem to another room so that I could hook up the PC with an Ethernet cord. However, when I went to move the router and modem, the only coaxial wall socket in the room didn’t work and I have no idea how to fix that. I know that there are a few other options outside, but I am unsure what my next course of action should be. I know about Powerline adapters, but I’ve heard that if the room that the router is in has a different circuit than the room the pc is in, the Powerline adapter won’t work. I’ve also heard about wifi cards, but I am not sure if I want to pursue that just yet. Thoughts?
