MoCA Setup Help

Hi...I was wondering if somebody with some MoCA experience could help me out. I just can't get a stable connection and need it for TiVo to work right (1 Roamio Pro and 4 Mini's) as Ethernet has to go through switches the way my setup is and TiVo says switches don't play nice with TiVo Mini's.

I had Comcast X1 prior, so was already setup for that, but switched over to TiVo a few months back, as I was sick of unplugging the X1 boxes every other day to reboot them as they'd freeze up often. My cable layout from that Comcast setup is:

Line in from street --> MoCA POE filter --> Commscope CSAPDU9VP Amplifier -->then cables split off to each room.

The amplifier is also my splitter. It was added by Comcast for the finicky X1 platform that needed my power all in the same range and I think I needed a good boost to get there.

In my home office room, that's where my cable modem is, which is a Motorola SB6183 with 8 channels. I added a PCT 1-port bi-directional cable TV HDTV signal booster with passive return path right before the cable modem in the office, as it's gives up to a 15 db boost. My cable modem without it was getting around -9 to -11 db range on each channel and was ranging in speed from 90-110 mbps. After adding the booster, all channels are now in the 4 to 6 db range and I now get 165-180 mbps when connected directly through Ethernet to my PC, so it made a significant difference.

Per TiVo's suggestion, I bought the Actiontec ECB2500C adapter the other day to try to get MoCA working. I first plugged it in right before the PCT 1 port signal booster, and when I checked to see if I had internet, it wasn't making a connection. I took the signal booster out, and now have an internet connection, around 50 mbps just from taking an Ethernet cable directly to the MoCA adapter and testing it on my laptop. However, now my cable modem speeds are back down because I removed the signal booster. I think it may work with higher speeds if I put back the PCT 1 port signal booster and put the Actiontec adapter between it and the modem instead of in front of both. I haven't tried that yet, as I'm still troubleshooting the other issue (below) which is more important.

If I go to the room where my TiVo Roamio Pro is, it can now connect via MoCA to the internet and all seems to work fine on that box, verified by disconnecting the Ethernet cable from the Roamio and still having internet just through the coax. However, if I go to my Mini's, they still can't establish a connection through MoCA to the Roamio. This is the bigger problem, and why I'm here. My feeling is the Commscope CSAPDU9VP Amplifier might be the problem, as everything feeds back to that, as it acts as the splitter too. Am I right in thinking this? And if so, what other options do I have? It would seems as though I'd need some type of amplifier, but also need to have an 8 port splitter. This is where I need help, if this is what it sounds like is causing the issue for my other rooms Mini's not being able to connect over MoCA to the Roamio.
