MacBook Pro 2010
Running ubuntu minimal 13.04

I want to connect my laptop to wifi,

but, wlan card is not shown:

iwconfig

Code:

lo        no wireless extensions.

eth0      no wireless extensions.

Although:

lspci -vvnn

Code:

What does
ifconfig -a
produce for you?
if it shows a wireless interface it may be as simple as
sudo ifconfig wlan0 up

Problem was with the drivers for my network controller.

Solution: install drivers for bcm43xx
