Converting Cable TV cable to internet?

VampLena · Jun 28, 2016

So im moving into a new place, and they dont offer Cable internet in rooms, just Cable TV. They have Internet access PCs in the rec area though.

Is it possible to use the cable TV coax and rig a Internet solution from that? I really want a wired ethernet connection in my place. I've heard of Coax to ethernet stuff, but im not too clear on how it works.

Thanks

Do you own the cable account? if not, nothing you can do.
If yes, talk to the cable company on adding a cable modem to your room connection

What you are probably thinking of is what is called MoCa, Multimedia over Coax.
What you first need to understand is there is cable types and there is protocals.
A cable is simply a physical item defined by things like how many wires it has in it, and what frequencies it supports; a protocol is a specific format that data is sent/received in.
Coax is a cable, cat5/cat6 is a cable
Docsis and Ethernet are protocals.

You can use a Moxa adapter to transmit Etherent data over an existing Coax cable. This requires you to have an existing internet connection (typically using Ethernet) to plug into the MoCa adapter to then convert it to be transmited over a coax cable.

If you don't have an internet connection then bottom line you need an interent connection from somewhere.
If your room has its own cable tv account with the cable company then you can get cable internet. If the building owner has 1 cable tv connection and splits it to the rooms then there is nothing you can do to get cable TV unless the building allows you to have your own separate coax connection (and then you will have to pay for TV and Internet through the cable company).

There is no way to just fabricate internet data out of a coax cable that only has TV data on it. You need the cable company to be sending you internet connection (using DOCSIS protocol) over the coax cable that you can then use a DOCSIS cable modem to decipher and then convert to Etherent for your computer.

Well, the building owner has both cable tv and the cable internet in the rec area, so I want to imagine it should have internet on the wire going to the rooms.

You can only use 1 cable modem per connection. The line going to the building is 1 connection, how many rooms it splits off to is irrelevant.
Thus if the owner already has a cable modem there is no way for you to have your own modem from that cable connection.

Here is your options:
1) Talk to building owner about hard wired Ethernet drop or using powerline Ethernet adapter.
2) Deal with it
3) Talk to building owner about having your own (meaning pay for it) hookup to cable company for TV and Internet.

Thanks, I'll have to talk to the building owner then.
