/diy/ - Do It Yourself

Hi I have a ltitle puzzle in my new apartment and it may be more of a /g/ question.

There are Rj45 jacks and the coax outlets wired in my apartment. They all lead to a switch box in the 2nd bedroom walk-in closet.

I would like to use the cat5 J
jacks for my living room media center and part of my overall home network and partly becuase I detest using WiFi for any kind of streaming and to rely on it for things like my automated aquarium controler. If the hardware and infrastructure exists I'm paying enough rent to take advantage of it.
Sadly the building landlord idiots and even worse comcast (which I have no choice in using becuase my building is wired ONLY for comcrap) have absolutely no idea it exists or how it works or is wired. I assume no one cares becuase most of the normie plebs clog the airways with wifi a anyway.

Now I opened the switch box and I switched where the coax splits and what seems to be a hub or sorts for both data and another for the conventional telephone.

I've tried testing these jack and it only works port to port (ie if I connect my modem/router to a wall jack I will only get conectivity to the terminus on that weird hub in the switch box). Obviously an actual switch/hub is required and whatever that box is, it's just an organizer.

Make things even more confusing on that data hub there is labels for living room, 1st br, 2ndbr and also a "feed" but to what?

the company that makes that is called open house but google hasn't really turned up much other then products for smart homes.
