[Signals] Options, what to do?

Ok in my office I have a dedicated leg for my cable modem. Straight to the modem, my signal levels average around -1 to -4 db downstream with 4 channels bonded. Pushing around 51-52db upstream with 3 channels bonded.

I need to add a comcast dvr to the same room/leg. No option for another line to the room.

Using a 2 way splitter will drop downstream to around -4 to -8db and similar upstream as stated above.

Adding a 10db amp pushes downstream signal to around +4 to +6 with many many uncorrectable errors and similar upstream as above.

Using a 3 way splitter with 1 leg capped, makes downstream signals around +1 to +3db with hardly any errors, but lowers upstream to 57db and only 1 stream, instead of 3 streams.

So which option should I go with- which would be best? Speed stays consistent in all options: around 36 down, and 6 up (Blast service).

Everything using quality cabling, connectors, and splitters, mostly comcast provided. Amp used is an RCA DT100M.

Thanks for the help!

I do this for a living

ummmm you know adding a splitter raises your upstream right?

so adding the 2 way pushes your upstream to beyond max transmit, you wont see it, but the CMTS does.

i would say get comcast out to fix your high upstream, then it wont matter what you do to the line, or have them do it when they are out.
I'm better than you!

As stated above, you need to have a tech out to adjust your signal. Your upstream will cause issues even without splitters installed.
