I just purchased an iMac (don't worry, the question is still somewhat PC related), and I need to connect it to the internet. Of course, airport extreme is expensive and hard to come buy so that's a no go. Our other computers are in the next room, and I have a wireless router. It has 4 spare ethernet ports on the back.
So my question is, if I run a cable from one of these ports to my mac, will it be internet ready, or are the ports on the router only for input devices?
