I have been with Tivo since the first box and finally in 2013 I have stepped up to streaming between boxes with MOCA. My house is newer and wired with coax properly. There is a splitter outside, one for cable modem in my office and the other for my cable entry point in my basement. I am using one splitter in the basement to feed both of my Premieres. My MOCA is working perfectly now. Signal strength on first premeiere in the 90's, the second, low 80's to upper 70's. I want to add another splitter to send the signal up to the attic where the coax is for the rest of the house. I have a TivoHD upstairs and would like to expand once the Tivo Mini is released. I am hesitant to call Comcast to ask them for amplifiers or MOCA questions about speed and bandwidth. Right now I am not paying additional outlet charges or renting any of their equipment, save for the two cable cards. I am about to split the signal with a 2mhz splitter to send the feed up to the attic. Based on nothing, I assume the signal strength will be compromised. What is the best thing I can add (or do) that will allow me to truly have whole house MOCA, with acceptable signal strength, and not pay Comcast for additional outlets. I am already paying for their highest tier of programming and internet.
