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!
