I have started a thread on the Comcast CATV forum on my whole home DVR installation I have set for next week, but this is more about the modems I have installed. I have an Arris CM820A for HSI and an Arris TM602G for CDV. I am wondering if the MoCA from the whole house DVR will cause problems (interference) with the HSI and CDV modems. There are five devices in the setup.
I don't know about the latest ARRIS modem models, but the newest Motorola ones say that they are equipped with an "Internal Low Pass Filter to eliminate MoCA signal overload" (like my SB6121: »www.motorola.com/staticfiles/Sup···heet.pdf).
