Is this even possible? I'm a networking newb. I have a PS3 connected wirelessly. I haven't sprung for a bridge/adapter nor a router to DD-WRT yet. Can I take an ethernet cable and connect it from my PS3 to my HR22 which is 2 feet away? I know the HR22 has a daisy chain but is ethernet treated as strictly in or out? Is the back of the PS3 in only?
