I want to add (rather say install) a wi-fi card to my Sony vaio Laptop... Its model no.is- VPCEB45FG. is it possible???? I dont have any idea regarding this, so i want some help to gather some knowledge on this matter. Actually most of the newly launched Vaio laptops have in-built wi-fi card (besides bluetooth and wireless lan) and i want that in my Vaio too.. Is there any way out?????
