shouldn't this be the problem for the cable company? Why are you tackling it? In the old analog days, the signals are taken at the output of the splitter; but with digital, I am not sure.
Comcast tech split signal from "in" cable to HDTV and my Motorola modem/router. Cable connection no good. If I connect m/r directly to "in" cable and use no splitter, system works perfectly but then no HDTV connection. We get one or the other. Has anyone had this pleasure?
