Is a 'Wireless' wireless AP possible?

Hi, I have my DSL router in the master bedroom and cannot move it to any other room in the house. I want to set up an access point in my living room. However, I don't want to connect the two via ethernet. Is it possible to have an access point where the router and AP can communicate sans ethernet cable? If so, is there a special piece of hardware I need to purchase? I currently have a Motorola 3347 in use through Century Link. I have a Netgear WNR2000v3 laying around that I was hoping to use as the AP, but I don't think it's possible without connecting via ethernet. Thanks!
