    I have been monitoring my power and noise levels for the last few weeks and am wondering if anyone can tell me if these levels and variations in levels look acceptable? (images below)
    Service Provider is Comcast in the Lebanon/Hanover NH region.
    Model DPC2100R2
    Hardware Version 2.1
    Software Version dpc2100R2-v2.0.2r1256-100817as

    Thanks,
    ~ John

    The variations are fine.

    Do you know, this is an Irish forum btw?

    Thanks, I did note it was not a U.S. based forum after I submitted but being married to one of Irish decent knew I would be in good hands. Thanks for taking a look.

    The SNR looks very healthy and can easily handle even the most delicate QAM modes for the DOCSIS modem. Small fluctuations would be expected and if the graphs has flat lines I would think you live in a lab!

    Power level not even reaching 50 dBmV is another good sign.

    That connection looks perfect to my eyes!
