Splitters and modem power levels

  • Recommended downstream power levels are -7 dbmv to +7 dbmv
  • Recommended upstream power levels are
    35 dbmv to 49 dbmv
    (Modem manufacturer, Arris, recommends 45 dbmv to 51 dbmv)
  • I  have a necessary splitter that splits to my cable modem and to my tv.
  • Even after that split, my downstream power levels are peaking at 7+ dbmv and my upstream are below manufacturer recommendation.

I decided to see what the levels looked like after adding an additional splitter and it actually makes my levels more in the median of where I want them.

My question is: Should I leave it there, or do you think I'd be prone to problems?
