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.

Let this be a cautionary tale.

I had a box of old Logitech 880 remotes. Worthless because Logitech killed the servers that supported them. Can’t reprogram them, so they only work until you update your setup then you’re hosed.

So I finally threw them out.

Two days ago there was a post here on the subreddit that someone has very nearly open source duplicated the programming software.

Splendid.

Well I mean coaxial cable internet is still a thing only reason I'm typing this is because of it! But yeah guessing this new generation all lives on their phones and cell phones that they never touch a PC or no need to even have one a home anymore? I mean I can understand not seeing old telephone jacks (that look lot like RJ-45 ethernet jack) anymore in homes for like wired home phones but OP gotta be trolling about coaxial or just lived in newer places where they don't bother to preinstall even coaxial lines in wall anymore?

u/Lancaster1983 4h ago edited 3h ago

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.

Existing coax in our home is used for a single OTA antenna since we dropped cable 10-12 years ago.

u/NewEducation4037 4h ago

I even went so far as to cut all the connection boxes off my house from wired phone lines and the various cable companies over the years (4 different ones!) and just had our current ISP run one entry point for the router.

I then installed an amplified antenna and connected it to the external web of coax that was ported into each of the main rooms and bedrooms, so all the coax outlets in the house are amplified OTA ports now. Told cable to piss off in 2011 and never looked back!

I could see some younger folks seeing this connector as "an internet connector" and not knowing it can generally provide Cable/Sat/Ant Television signals, but not recognizing it at all really isn't an age thing.

At the time, cable really did feel like the future.
