MoCA problem when adding a 2nd Mini

I'm having a strange MoCA problem when adding a 2nd TiVo Mini.



Here is my setup:

  • Apple AirPort Extreme connects directly to my TW Cable Modem

  • Roamio Plus connects to the AirPort Extreme via Eithernet

  • Roamio Plus also serves as the MoCA bridge

  • Mini "A" connects only via MoCA


At this point all works fine.



When I connect Mini "B" via MoCA, it cannot connect back to the bridge in the Roamio Plus. If I power off Mini "A" and "B", reboot Roamio and then bring up only "B", it works, however after starting "A", now it does not work. :confused:



The other complexities are Time Warner's lovely Tuning Adapter, however I have this properly split prior to connecting the Roamio and Tuning Adapter.



As far as cable splitters go, I have the following:

  1. In the closet, there is a 4 way splitter (5-1002MHz)

  2. One of these connects to a 2 way splitter (5-1002MHz)

  3. I also have a 2 way splitter just prior to the Roamio and Tuning Adapter 2 way splitter (5-900MHz)




I have read all about the splitters needing to be 2GHZ, TiVo's specific recommendation seems to be "at least 1.2GHz".



Thinking that my problem was the splitters, I attempted to replace splitter #3 above, with this one, Ideal 2.4 GHz 3-Way Splitter, which is rated 5 MHz-2.4GHz. Unfortunately that did not resolve my issue.



Previous tenant / lazy cable guy left the hodgepodge mess of outdated splitters, not me. :D



Questions:

- Should I also replace #1 with a 1-4 way splitter? (I don't actually need the 5th connection.)

- Is there any reason that I would need to "isolate" my Time Warner Cable modem from the MoCA cable TV/MoCA stuff?

- Frankly I don't understand how the current setup with just 1 Mini actually is working, as nothing was previously rated any higher than 5-1002MHz!

- Has anyone else run into issues with multiple Mini's on the same MoCA network?

- Why does Time Warner insist on using the stupid Tuning Adapters? alas this last question belongs in another forum. :mad:
