I was wanting to do it this way because it'd be easier. I've got the modem in my room, than there's a really long ethernet cord running over to my dad's room on the other side of the house, he was wanting to hook up my brother's computer(next room over to his) But it's hard to get an ethernet cable long enough to reach across the house, so he was wanting to plug the ethernet cord that's already plugged into his computer, into the router, than have a shorter one off into his computer, and another shorter one off into my brother's computer.
