Ok, well what would I get to hook up to my router? I have 3 computers in my room now (Cousins, Friend's, Mine... freeloaders.. Using my internets..) but we are 1 port short on my router from having everyone in my house have internet, so im wondering what should I get to hook up to my router? Another router or a switch? From my understanding a switch would be better, but I could be wrong.
