Hey! So I live in this huge house where there’s a lot of people rented here. There is only one router and it’s extremely far away from me. I use internet a lot so I need a router of my own via cable not WiFi. What are my options? There’s xfinity here. I had my own xfinity router from my old house, plugged it into the tv cable and I don’t get service. What could I do to have my own router and Ethernet ? Thanks!
