Comcast has once again been most unhelpful, I would say their usual Cluster-F*CK - Just need to get wireless coverage in big 2-story house.... My poor old mom took all of her old cable boxes, analog converters, coax cables, etc. to Comcast and told them she had two new HDTVs - one up, one downstairs, and two PC's, one up, one down. They gave her the following equipment. ONE DVR, and one wireless N router. The house has coax cable split at the drop upstairs, running downstairs. Comcast provides her bundle (meaning phone, internet, TV, all come in over the coax, of course...) Based on the fact that if we place the wireless downstairs, the upstairs is dead to wi-fi. If we place it upstairs, the downstairs is dead (very thick walls in her big old house). With all that said, what is the best way to get coverage to her entire house? I have another dlink wireless N router that we could use, as well. Don't we need another DVR (one for each HDTV?) Can I get a coax-to-ethernet converter and put two routers in the house - one up, one down? That would give us the coverage we need, but can you do that?? If so, how do I configure those? Somebody please help, I can't believe Comcast really expected a 76-year old lady to figure this out!!
