Okay, the computer is detecting the card and loading a driver for it.  Things
to check:

Does this card require firmware (Intel usually doesn't, but check anyway)?  Is it 
present?

Does ifconfig show the interface?

Does rfkill indicate that the card is disabled?

Does scanning from the command line using "iwlist scan" from wireless-tools
show your network?

Are there known problems with this card and the driver included in your
current kernel version?
