Moving modem to new room, cable identification issues

Looking to move my modem to a new room, but having issue tracing back the correct Xfinity cable. I see it runs into a junction/splitter, assuming I can branch off that and run a new coax into the room in question?

I’ve attached a photo of what I’m seeing, it’s just a sold black wires running into the splitter. Assuming this is the primary line I can split from.

is this something I as a consumer can do or does it require a technician?

@user_rr1cr8 - the picture looks like this is your Demarc point, anything going outside of it is the Xfinity's responsibility, anything going inside of it is the home owner's responsibility. You can do anything you wish inside your home. Do you already have a Coax outlet in your "new room" ?

Not yet, if I can fork off this point. I’ll run a line from it too the new room. Or repurpose some of the excess wire that’s there

Yes, in theory you should be able to. If you are planning to disconnect the current home run cable and connect the new one to the same "out" port of the splitter and but if you are planning to add new cable to the splitter pay close attention to the ports on the splitter, to see if the "out" ports have different dB specs, also the high quality F-Type connectors for the new home run coax cable should be terminated with a compression tool.

FWIW. The ports on a splitter do not have "different MHz specs". A splitter has only one MHz rating / frequency range. You must mean different dB / loss ratings.

@EG, yes I meant dB.

That's a 4-way splitter. And it looks like only 1 output port is being used. Some of the ports have terminators on them. If you only need one line, you should change that out to a two-way splitter, or no splitter at all for less loss.
