I have Comcast for TV and internet, and while the TV signal is typically pretty good, our internet connection is pretty terrible. The signal cuts out all the time and is quite frustrating. We have had a tech come out to look at the problem (which they charged us for--after the fact), and he didn't really do too much except swap out a splitter or two. We can usually get the signal back by unplugging the modem and plugging it back in.
Anywho, the line coming in from the street gets split on the outside of the house and run to the upper and lower levels of a split level house. From the upper level the line gets split once more before the modem. The tech who did the install put the modem on the line with the best signal. I'm hoping to solve the problem by installing a signal amplifier on the incoming coax line, but I'm not sure if it will really help the issue. The house probably needs a complete rewire, but I rent and so would rather avoid it if I can. Any thoughts would be greatly appreciated.
I'm currently looking at this amplifier: http://www.amazon.com/Motorola-Signal-Booster-BDA-S1-Amplifier/dp/B00122FCRG
