LAN coax doesn't work with router?

Hey guys, I want to move my setup to my room, but since it's on the opposite side of my house, my WiFi doesn't reach there (and I don't have a WiFi card). There are LAN coax wires located in my room and in the family office (where the router is currently located) and I'd like to move it to my room for Ethernet.


I've tried moving the router to my room, but after installing it to the coax wire, it doesn't recognize it and doesn't connect to the internet. It's pretty rusty and hasn't been used for over a decade, and I had a little bit of a hard time connecting the router to it (with a wrench). However, when I installed it back in the office (the wire in the office is nice and clean) the router worked fine. What could solve this issue? Thanks!

As far as old coaxial ethernet is concerned, you don't necessarily need routers at all. unless your network gets huge and complicated.
The basic topology is such that EACH device attaching to the coaxial cable is attached to it with a BNC T bit and each end of the line has terminator block.
I'm pretty sure network cards that had BNC connectors died off around 2000 or so. Adapters still exist though.

It also seems that there are routers to use existing TV coaxial cabling for network usage, this is NOT the same as old legacy coaxial ethernet.

Googling for coax lan gives quite few images that show possible ways to build the network based on the cable type/setup

This. Just because the coax outlet is in your room doesn't mean it's hooked up. It may have been disconnected in the past. Do you have Cable TV service? Try plugging in a cable box and TV in your room, and see if it works.

If it doesn't work, the coax outlet in your room probably isn't active. Walk around the outside of your house and find where the Cable TV comes into the house. It usually looks something like this, or the splitters are inside a box, or underneath a metal flap.

Once you find it, make sure all the cables are connected via splitters or a junction box. Sometimes they are disconnected if the homeowner has switched to satellite TV (satellite has weaker signal strength, so unused cable is often left disconnected). If there's just a single Cable TV wire going into the house, the distribution junction (which splits the signal to the different room coax outlets) is probably somewhere inside. You'll have to find it and reconnect it.

Router: Actiontec MI424-WR Rev.D (Verizon Fios)

I just plug the wire straight into the router and screw it in. I honestly don't know if the wire in my room is active or not. They go straight into the wall, they don't connect to any wall coax outlet or anything.

Nope. This comes out right where the cable goes in: http://imgur.com/CSBi7jz
