You could maybe replace the 2way for a 3way then becuase your signal at your modem is still a bit high according to what you posted. if you look on the face of the splitter it will tell you the loss . a 2way is 3.5,a 3 way is 3.5 on one leg and 7 on the other 2 legs,a4 way is 7 on all ports.

I work for charter comm. in OR In our cable system the ideal signal level is between 2 and 6 db also the power level is ideal around 42 dbmv. the higher your incoming signal the lower your power level will be.also most cable modems will go offline when the power level goes below 30dbmv or above 60dbmv. If you can get ahold of a quality 2 way splitter you will drop your signal by 3.5db and increase your power level.dont use a 3way or larger splitter they will decrease your signal by7db or more. hope that helps
