What you sometimes have trouble with is the TA not being able to talk back through the moca interface and/or the moca interface not being able to communicate through the TA... you do not want these two devices daisy chained together. Since the prime is one directional, it does not matter if this is after a device (either the moca adapter or TA) but usually the prime is the device on which you want the best possible signal and going through a device may degrade it. Going through a 3 way may degrade the signal to/from the TA and/or moca adapter too much where one may not work properly (depends on other wiring) in which case I would try one of the other methods using a two way splitter and see if it improves. My most recent moca install, I actually went to the adjacent bedroom to house the moca adapter and 2nd floor "switch" (as that room also needed ethernet for the daughter's computer so the switch provided for both upstairs bedrooms and office) and used its direct coax back to the main distribution (4 way splitter, one to each bedroom and one to main living area) to get the ethernet to the first floor where the router was and connected 2nd floor prime and computers to that switch... prime had its own cable off the 4 way. When that location added SDV, I split it in that room for TA and prime with no problems as good signal to 4way.
OK, let's make this a bit more complex! So far I've tried everything suggested (I think) but am still having signal issues.
In my original post on this issue, I left out a part of my set up. I did this to try and keep things simpler, and also because I am not having issues on the other part.
We actually have TWO Primes, and TWO TA's. I will refer to them as P1 and TA1 (working fine), and P2 and TA2 (weak signal).
P1/TA1 are located in the main house, and we are having no issues with them. They are connected thusly: feed from 4 way splitter under house to a 2 way splitter in the house, one feed to cable modem and the other feed to the MOCA, MOCA to TA, TA to Prime. Although this goes against your recommendation, it's working fine. A WMC PC in the main house uses this Prime.
In the garage room (where we are having our problem), it goes: feed from 4 way splitter under house to 3 way splitter in garage room, 3.5db to Prime2, the other two 7db feeds to TA2 and MOCA. So with this we have weak signal issues.
I have tried feed from 4 way splitter under house to MOCA, MOCA to TA2, TA2 to Prime2, as we have in the main house, but the signal was slightly weaker than now.
So now I know of only two more options: use an amp under the house in place of the 4 way splitter, or move P2/TA2 into the main house near P1/TA1. If I do the latter, how should I connect everything?
Feed from 4 way under the house to a 3 way in the house, split feed 1 to cable modem, feed 2 to the MOCA, MOCA to TA1, TA1 to Prime1, feed 3 to TA2 then to P2?
Or, I can use another 4 way in the house: feed 1 to modem, feed 2 to MOCA, feed 3 to TA1, TA1 to Prime1, feed 4 to TA2 then TA2 to P2?
