Tivo Bolt MoCA Bridge causes loss of Internet

When I turn on the MoCA Bridge on my Tivo Bolt my Internet stops working on all my devices.  I have tried 2 different Tivo Bolts but I get the same issue.  This issue started happening on an older Xfinity Modem so I got a new Xfinity modem but the issue remains.   I talked with Tivo and they said the modem is not allowing the Tivo Bolt to create a MocA network.

Does anyone know what I can do to fix this?

Thank you
