Just upgraded Verizon FIOS, and in the course of doing that Verizon changed the connection to the ONT in my home from a coax cable to an Ethernet cable. The router they installed is the G3100, but it's very expensive, and I don't need its wifi because I have my own Google mesh system. All I need is an Ethernet port to plug the mesh network into (and a couple of ports for other devices that I prefer to hardwire rather than connect over wifi, like my primary desktop and my Ooma unit). What kind of hardware do I need to convert the Ethernet connection from the ONT into a few separate Ethernet connections for my mesh network and other devices? I'm not stuck with the $299 G3100 just to connect some Ethernet cables together, am I? Thanks!
