Hooking up two cable modems to two separate coaxial ports for internet

[Imm0rt41]

Ok so my mom paid to get a secondary coaxial port in the house, its running from the box outside upstairs to my room. We already had a coaxial port downstairs, and to that one we connected our cable modem and router. However, the wifi connection is horrible going across the house and so I wanted to see if I could buy my own secondary cable modem and hook it up to the currently empty coaxial up here in my room so that I could get ethernet connection. We have Time Warner Cable and they said that if I wanted to use the cable modem on the coxial upstairs for internet, they'd have to disable the cable modem downstairs. I'm wondering if there is any way I can hook the cable modem upstairs and get internet out of it without having the one downstairs disabled. My mom doesn't want to pay to have Time Warner Cable bill us a second connection, and she doesn't want to just run a really long ethernet up the stairs either, and for what I do with my computer a wireless connection won't work very well

So, in short, can I connect a second cable modem to a secondary coaxial port, and get internet access from that cable modem while retaining the internet access to the cable modem already installed downstairs. Thank you!

Sounds like a perfect place to use the oft' forgotten Powerline Ethernet option...

No you can't without TWC either disabling the one downstairs or giving you a second bill. You may want to look into a wireless repeater or running a network cable outside of the house, or having an electrician pull a cable for you.

What do you mean by running a network cable?

 

[Snipergod87]

A Cat 5E cable, however as Farving suggested a power line adapter would work well. You would plug a network cable (Cat 5E) from your router into a power line adapter plugged into the wall, this will put the network connection over the electrical wiring in your home. You can then put another power line adapter in the place where you need it (you room or whatever) and you can then run a network cable from that to your computer, or get a power line adapter that makes a wireless network and connect wirelessly.

Network cable=Ethernet cable.

Ok so I was confused about the power line adapter, it actually transfers the ethernet signal through the house electricity? Like getting multiple of those adapters (with one hooked into the router by ethernet) would actively transfer ethernet to any AC outlet (that has another adapter in it)?

It will transfer Ethernet through the houses AC power lines (hence the name power line), any AC outlet would receive the signal and you would need to plug in an adapter to convert it to normal Ethernet or wireless.

On some home circuts air conditioning and refrigerators may weaken the Ethernet signal depending on how the house is wired.

Since you have a coax cable running to the upstairs room you also have the option of use a device called MoCA. This run network work the cable tv wires. Exactly how you cable it varies a bit but you would connect one to the tv coax with a splinter near the modem and a second in the other room. You would then plug a ethernet cable from the modem into this new moca box and the signal would come out the ethernet port in the other room. These generally work much better than powerline networks especially if you have a simple coax path to the other room. They are kinda expensive though compared to other solutions. I

If you needed wireless in the other room you would plug a AP or router running as a AP into the MoCA box in the remote room.

Hi. What if the AC outlet you plug your two different powerline adapters into are on two separate breakers?
