OK - so I have a Roamio Plus and Mini, and both COAX and CAT5 at each location. I connect the CAT5 to the Plus for internet and the COAX to both the Plus and mini, and they will communicate thru Moca on the COAX, is that correct? Will I also need to connect the CAT5 to the Mini, or will it get everything it needs thru Moca? Any benefit to connecting the Mini to CAT5? Thanks.
