There's used Japanese WHR-HP-G300N router is being sold nearby. But I'm not sure does it support WDS? Some sources say NO, some say YES, some say US version supports after software upgrade. Does it support WDS in reality? What software do I need to upload to make it support if necessary? I need to extend a G54 wifi network to 3rd floor. base AP is conventional (moderate power) router. So I want to place a High Power Buffalo model in my room near door to access the network from other spots through WDS. I've tried this spot near door with Toshiba notebook (Portege R205-S209) So I think it should work, if WHR-HP-G300N is really HP model.
