I'm trying to do the same thing. Just got wired setup working in my new home. (cable modem > dlink 860 feeding 8 ports around the house).
Now I need to add wireless, hoping I can figure out how to setup the new Buffalo wireless router that's on its way into acting as a AP. It does have dd-wrt if that helps. Very much a newb in all this, just been running simple wireless networks the past 10 years..
New Game PC running!
