I'm trying to help out my nephew who's bedroom appears to be terrible for receiving a Wifi signal. I know that a DECA based system is not intended for what I am about to ask. But, for the sake of this discussion, I just need to know if it will work. They have a SWM based system, with NO Whole Home DVR service. They have a CCK connected to a DVR that's across the room from their wireless router. So it has a good signal. If I add a DECA in his bedroom, with the coax connected to his existing receiver and the the Ethernet output connected a network switch, and then to his PC and Xbox 360. Will he have Internet access on those two components?
