Can't print using ReadyNAS duo

Thanks for the previous post. It has helped me print from my Vista computer that is wired to my Linksys WRT54GXv2 router. The issue I have now is that when I attempt to use the same instruction for my netbook (XP) which is connecting wirelessly, I just keep receiving the message that is it unable to connect whether I use the local hostname or the IP of the local host. I've managed to ping the NAS itself using the IP address but not the local hostname. From within the router I'm configured it so the UPNP is enabled and I can see the NAS link for Frontview but that is as far it goes. I do think think this is some configuration problem with the router in terms of the wireless setting but I've looked through this setting and nothing is jumping out at me. Can anyone help?

Thanks
