I'm wondering this question. I have wiring for three rooms in my house, living, bed, and the loft. About 4 years ago I got Comcast internet so the signal was only being pumped to the loft. 8 months ago I got Comcast cable TV so the signal was being piped to all three rooms. If I go back to DTV, can they splice in the bedroom lines and leave the loft line alone? Will I continue to get Internet without issue? Will DTV work without any interference?
