Enable Bidirectional Communication

Hi, I hope someone there can put me out my misery. I am trying to wireless connect my Dell V305 to my laptop. \the laptop is in a network with my desktop and connects through the router. I have loaded the drivers as per installation disk but it will not connect as it just comes up with the message "Enable Bidirectional Communication". I have followed all info and gone to printer properties but could find no box marked thus. I am running windows 7 if thats any help.

I cannot find help anywhere else so I would be very greatful as a first time user of this forum.

Thanks Davec
