It looks like this is what's happening. The Mini still functions over MoCA with internet down but with Roamio's ethernet link up.
Losing ethernet link on the Roamio disrupts the MoCA network, presumably because the bridge is interrupted.
Thanks for the suggestion!
Does anyone know if the XL4/Elite behaved the same way?
