Upgraded my modem/gateway/router from SBG6900 and G34 and immediately had problems with my TIVO mini’s being unable to connect to the Host DVR. Problem lasted a couple of weeks with no help from ARRIS (assured me nothing internally was being blocked) or TIVO (couldn’t tell me what protocol they used for discovery).
Problem was solved when I discovered the setting for “Zero Config” (Bonjour type discovery) under Advanced > Device Discovery > Zero Config was disabled. Enabling it allowed my TIVO mini’s to immediately connect to the host DVR. Note that this setting is on a page that is mainly about UPNP.
This could affect anyone else who has printers or other devices that use the Bonjour Zero config capability to connect to one another.
