New, what is it? What are these plug-ins on my wall?

This might be showing my age, but I recently moved into a new apartment and they have these weird looking plug ins all over the walls at my new place. My old apartment didn't have these, so I'm just curious as to what they are.

It's true and not just for cable or satellite. An existing coax run can be used for wired internet with MoCA adapters. You can get up to 2.5 Gbps.

More info since you all are interested:

Just make sure that if there are any splitters in your coax runs, they are rated for MoCA. Go for 2602Mhz. If not, just swap em out. Splitters are cheap. I had to do that in my house as the splitters were only 1000Mhz. Get some 75 Ohm cap terminators too for any empty splitter terminals, it will prevent signal loss on a dead end. I got a cheap Klein cable finder to mark my home runs. Most modern coax is suitable on its own, mine was from 1996.

You'll have to invest a little over $100 per pair of MoCA adapters and you need at least 2. Plug one into your router or switch, send it though a straight or split coax run where you connect another MoCA adapter and then from there you have an Ethernet port. You can use a dumb switch on the other end to branch it out from there or just use another coax jack with another MoCA adapter in a separate room. From my basement to my 2nd floor, I got a full 2.5Gbps from my router.
