I move into a new home which have seven cable outlet in different room . one of the bedroom I turn into a office but the problem be that I only have one cable connection in the room . the connection do okay with either the cable modem or the hdtv but not with both connect . the cable modem would not connect with the tv connect to a splitter . I connect the amplifier and run one cable to the tv and the other to the cable modem . I cross my finger and plug it in ... now I have a great cable internet and hdtv signal , both from one cable connection . the only thing I have a problem with be the 13 day it take from the time I order until the time I receive the item , but that have nothing to do with the item itself .
