    Hello. I live in an apartment complex so I don't have many alternatives, here is my situation:

    I have my cable modem and WRT54GL in my room. There is a splitter where the coaxial cable goes from my room to the living room though the walls. I want to get some sort of media center extender so I can one day connect a media center.

    I was wondering how I can conver that coaxial cable and use it as CAT-5 cable, while still allowing cable TV to run to it? Thanks!

    I don't think you can convert Coaxial to Cat-5. There are 8 tiny individual wires inside a Cat-5 cable, each carrying different information. In Coax, there is just a single, thicker wire running the length of the cable which is usually heavily insulated. Now, that's not to say it can't be done, as data can travel across coax (in the obvious case, cable modems).

    If you really wanted to do it you'd need to get a NIC (Network Card) with BNC connectors. That way you could attach coax cable to them. You'd need to get a coax cable with BNC connectors as well though.

    Over here, it's common for such wires to be run through a tube.
    These tubes have a diameter of 16 mm or 5/8".
    Sometimes larger tubes of 19 mm or 3/4" are used.

    If this is similar at your place, you should be able to run a new coax cable together with a cat5 cable through the wall.
    I did so, so i'm sure you can do this too, if you have such a tube.
    I ran a H125 coax cable (8 mm diameter) and whatever network cable was available to every room i my house.
    (i had different pieces of cable around).

    Ofcourse this is im my own house, and there were no cables in the tubes when i bought it, except the tube to the living room.
    Just a wire to get the cables in.
    But you should use the old cable to pull the new cables in.
    You will not succeed if you'd try to add a new cable to the exsiting one.
    Be very patient if you are going to try this yourself, and get help from some friend.
    One should pull gently from one side while the other one puts the new cables in the tube.
    Pull gently means do not pull very strong and certainly dont start jerking, you'll break one of the cables and that's when the sh*t hits the fan.
    If you get stuck, pull them a bit back (so reverse direction) and try again.
    Also, uncoil the cables before you start so you can put them straight in the tube.
    Else they get tangled and will get stuck in the tube.

    Hope this helps.

    No easy or cheap way to do this. Why not just use wireless?
