I have xfinity for internet service and my Son who drives me crazy with his Gaming PC components thinks he needs faster service. My wireless gateway modem is in my living room where it's wired to my cable box, TV, Phone and 2 PC's already. Is there a way to put his own modem upstairs in his room? It's too far and way too much work to direct wire to his PC. He has a cable line already in his room also.
