I searched this thing on internet and before I can suggest some thing
I want to know is your wifi card being detected on your system.
If possible for you just go to some friend who has a wifi and see if
you can see wifi of friends network  being detected
on your laptop.
If you are comfortable with command line
then post the output of
iwlist scan

If everything is working, the resulting output will yield something like:

wlan2 Scan completed :

If you get this output (plus data for other AP's), then the interface
is able to receive data (at least).

Post the results here.
