This might be a noobish question but i am not really familiar with wifi setups (never used, but need to know for someone). There is a wifi enabled laptop which uses a wifi card (some Aircard) which goes into a slot in the laptop & then a small antenna is attched & wifi is connected further. The person wants to use this card in his Desktop pc too, like taking that card & pushing it in a slot in desktop pc to connect to the wifi - that is a tata indicom wireless connection; (no simultaneous/sharing connection is needed). What exactly I need to buy to do that? (wifi card/ wifi usb adaptar? im confused as i never used those) also if i would need a driver/software cd for that aircard (which he had before i bought anything).... Please be a little descriptive in saying what exactly i need to buy & attach etc. Thanks.
