It is possible that the tech removed a spitter somewhere so the coax run you where using before is now disconnected. This is just an add on to the other recommendations posted allready.
Aside from the modem vs gateway issue and how it alters the need for an additional adapter, the diagram doesn’t address how the coax outlets would actually interconnect: the coax outlets can’t be direct-connected, as diagrammed, if the pictured setup is for cable Internet, since the modem lacks a connection to the ISP. You’ll want to make sure that the rooms and incoming ISP feed are interconnected using a MoCA-compatible splitter, and that a 70 dB “PoE” MoCA filter is installed on its input port to isolate/secure your MoCA network.

Oh, sorry, I guess I didn’t think about some things with the diagram. The modem is connected to a fiber cable and I’m not really sure how the two coax outlets connect, I just know that they reach each other somehow.
Hmm, then that changes things. It would definitely be helpful to get a brand & model # for the modem and router, as well as the identity of the ISP.
