Could you please post what you think is your wifi card?
Edit: To check what drivers your wireless adapter is currently using, you can run the following command in a terminal:
(Cntrl-Alt-T should open a terminal.)
sudo lshw -C network
"lshw" lists information on your hardware
"-C network" filters the output to only show the network class.
In the output, look for the entry with the description: Wireless interface.
