    Great info, thanks for uploading the video. I dropped out of college when
    some personal problems came up but I love to learn new things. Thanks for
    teaching me something new.

    Newbie question, how do I know, by using the SNR that my cablemodem shows
    on the modem webpage, if I have too much noise or little noise? for
    instance, I see that it says something about 36dBm in the SNR marker, does
    that mean that I am getting more signal than noise? By using google I have
    learned that there is a SNR for the signal on the coaxial cable, that can
    be affected by cable quality, splitters, installation, bla bla bla. What I
    want is to know if my installation is affecting the cable modem ability to
    get good signal and therefore good speeds.
