Okay, so I have Comcast and I already pay over $100 a month for two boxes, and we need cable in a 3rd room, is there a way to make that happen without another cable box. Could I somehow hook up the cable from the wall to a wireless router and then hook it up to a T.V. Thanks
You could buy wireless audio video senders. This setup would involved splitting the signal from the cable box and you would have to watch the same thing on both tvs but they do have built in remote control extenders so you would be able to change the channel.
