iw(list/config) can only handle WEP.

You need wpa-supplicant for this.

sudo apt-get install wpasupplicant

In /etc/wpa_supplicant.conf you put your ssid and password.

gksu gedit /etc/wpa_supplicant.conf 

Example:

network={
            ssid="ssid_name"
             psk="password"
}

Assuming your interface is wlan0 you can connect to it with...

wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant.conf -Dwext && dhclient wlan0

然后如果要开机连接
在/etc/rc.local中添加

wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant.conf -Dwext && dhclient wlan0

问题：
1.
驱动加载这一块还需要在实验，现在用的系统驱动已经加载好了。
2.
从解答中有iw，所以用iw可以执行，但iw只支持WEP
3.
