I have wireless internet from a local provider (HoodCanal) in my apt., I have it set up in my bedroom. Can I run cable TV from a different provider ( Comcast) in the living room? (I have 2 cable outlets). Without thinking and asking first, I recently ordered basic tv cable from Comcast and also ordered their self set up kit. Everything is plugged in and power is on and activated, but of course DUMB ME there is no signal or channels on my TV. What do I need? A splicer? I was trying to save some money, I'm on a tight budget. I think I made a huge mistake! ( dumb senior citizen woman).
