Certain commands can only be run by root; if you see

This is most likely caused by the lack of administrative privileges associated with your user account.
then you need to enter
Code:
sudo iwconfig
enter your password when prompted to do so.

Have you tried this?
Code:
sudo ifconfig wlan0 up
If that doesn't work you need to verify that the correct driver is installed for your wifi device.

You may need to install the firmware-broadcom
Try
Quote:
sudo modprobe bcm4306

BCM4306 driver issues

I have just run into a similar problem while installing Mint17 on a Dell Latitude D505. After many false starts I found the recommendations in http://askubuntu.com/questions/45912...-14-04-install, with a modification for the BCM4306 V2 device:
sudo apt-get purge bcmwl-kernel-source
sudo apt-get update
sudo apt-get install firmware-b43legacy-installer
shutdown computer; unplug network; restart; Wifi should work now.

If you have a different Broadcom card, see https://help.ubuntu.com/community/Wi...Driver/bcm43xx
I think the key is the purge command, because it also fixes the configuration files.
