cable modem

[bsxiong]

hi all,

I've been having problems with my internet cable modem. It's a motorola. Whenever i download huge files from the internet alot at a time, for a while, My internet connection will die on me. THen i will have to go and unplug my cable modem again. I think that it's all my modem. Will buying a new modem help me eliminate this problem? Afterall, this is a free modem that we got from Comcast internet cable provider.

Your Signal to Noise Ratio is borderline.

Do you have any splitters anywhere on your cable, like to a TV or cable box?
If you do then check the label on the splitter and make sure that it meet the below standard:
Rated at 1000MHz (or 1GHz) and the outputs should be rated at -3.5dB.
The closer the output value is to 0dB, the less your signal will be affected by the splitter.

ok, this is what i have.

From the Cable modem, we have a switch/router. One goes into my computer and one goes into another comptuer. THis is all that we have. The cable cord comes directly from the outlet on the wall. There are no extra switch between the cable cords. I don't share my cable line with my TV cable. We have two cable outlet.
