Is there a device that can convert coaxial to ethernet connection?

g_____g · May 30, 2017

Hi,

I may have the idea of this wrong, but I was wondering if there was any type of device at all that could convert the input from a coaxial cable to an ethernet cable to gain internet connection.

I plan to play games on a PC I just built, but I was looking through various solutions for joining a network at a long range from an access point with the best connectivity. I removed the coaxial cable from my cable box and plugged it into an old router I had, and I was able to get a wired connection to my computer.

I'm looking for other options because this old router is an Actiontec MI424WR Rev I, and just isn't optimal for gaming. I noticed several spikes that were even worse than wireless connection.

So, my question is, is there any device (switch, router, even a cable converter) that would allow me to convert a coaxial connection to ethernet? The ones I have came across are all ethernet to coaxial, which really wouldn't help me too much. If there is such a device, then recommendations and the type of technology used would be appreciated.

Thanks in advance.

A cable modem.

But seriously there's probably nothing that can do what you want to do.

Yes, for internal to your home there are MOCA converters like these -- https://www.amazon.com/Actiontec-MoCA-Ethernet-Adapter-ECB6000K02/dp/B013J7L6BW

Well, yes.

However, we'd kind of need to know all the other parts in your house LAN.

What type of connection comes into the house? Cable, fiber, DSL, other?
The Actiontec MI424WR leads me to think Verizon fiber?

What type of wiring goes through the house? Coax everywhere?

If you have FIOS with an Actiontec MI424WR router, you can get FIOS to enable the ethernet port on the ONT. Then you can use any ethernet based router.

And you don't even need that.
The default FiOS install is coax from the ONT to your router. That ActionTec.
Then ethernet out from that.

However...the internet signal already exists in the coax line from the ONT.
A splitter in the right place, and a single MOCA device elsewhere, can provide a stable, fast ethernet signal to a device at the other end of the house.
That's how my upstairs gets a wired signal.

Verizon fiber comes into the house. Coax wiring goes through the house.

This is exactly what I am trying to accomplish. What components would be required to do this correctly?

This is almost certainly very easy.
You have coax from the ONT to the Verizon router?
You wish to have a connected PC somewhere else in the house?
No problem.

The proper signal already exists in the coax.
In the coax that presumably exists in that location, a MOCA device connected to that coax. Ethernet out from that to your system.

I have one of these for my upstairs connection:

Assuming that coax eventually leads to all the other coax in the house, plug the coax into that, and a Cat5e into the RJ-45 port on that.
This should work. It is exactly how my house is wired.

Just for confirmation, are all of these MOCA devices meant to convert from coaxial to ethernet? They have all read 'Ethernet to Coaxial' so I assumed that it only worked that way. I feel pretty dumb now lol, but thanks a ton.

It goes both ways.
In a house without Verizon FiOS, but with coax everywhere...you'd simply use 2.
router->Cat5e->MOCA->house coax->MOCA->Cat5e->PC

Got it. I'm probably going to order one now, this will beat wireless by a ton.
