Brings up and down interfaces defined in /etc/network/interfaces. ex: ifup wlan0 for wireless network interface.

Gives you more info about your wireless interface. Most useful so far is iwlist wlan0 scan which shows information about all networks in range.

iwconfig wlan0 essid “MY_ESSID”
iwconfig wlan0 mode Managed
