I had been having problems off and on for months with disruptions in my Internet service. I had the cable company techs come out three times to diagnose the problem and they finally decided this was happening due to signal loss through the many splitters that previous techs had installed (instead of wiring the house properly in the first place). So the last tech that was out managed to reconfigure things in such a way that he could eliminate two splitters from the line and the cable began acting fine...for one computer. Apparently the signal was still not strong enough to make it through my router, so I was unable to use my home network until the problem was resolved. Enter the Motorola Signal Booster. I put this baby in the line and voila! no more problems.
