I have a Motorola 4 way amp. splitter with my cable modem and three Tv's hooked into it.A friend who used to work for cable said I should run the cable modem directly from a 2 way splitter instead of through the amp splitter.The amp is bi-directional/passive.What is the deal on this subject.Thanks for any responce.Hope this is the right forum to ask this in.- overtimeman
