    I'm rewiring my coax network and adding MoCA-compliant splitters in the process. I'm having some issues with signal strength to my cable modem however. Right now I am using setup A, but I am thinking setup B would be better as it results is less drop in strength due to the splitters. Am I correct in this?

    B is better, but I would use an amplified splitter

    B is better, as keithg1964 said. I'd highly recommend placing a 75-ohm termination on any wall plates or unused splitter ports.

    Thanks for the feedback. I have terminators on the unused splitter ports but didn't think about wall plates.

    Agree with the above (B is better, get a MoCA bypass amplifier if cable signal issues persist), but you'll also want to get MoCA filters installed ... one on the input of the top level splitter (the 2-way in B); on the input of your Tuning Adapter; and, possibly, on the input of your cable modem/gateway, depending on its MoCA compatibility.

    p.s. The diagram doesn't seem to provide a complete picture, lacking any network connections.

    What are the walljacks feeding? Mini's? If so, I'd dump the cable and run ethernet, then only use cable where you absolutely have to.

    B would be better in my opinion with one change. Come out of the 2 way splitter and have one side go to the modem and the other side feed the other splitters. I was using that for a long time. Then Comcast came out to fix another problem I was having and replaced my two splitters with a single powered splitter for free.

    Between the two, option B would be the better choice. However, a few follow up questions.

    1) If you connect your cable modem directly to the drop without any splitters, what do your downstream and upstream signal levels look like?

    2) Will all 8 drops from the 8-way splitter be used?

    3) What are the distances of your shortest and longest drops?
