how to connect to wifi that has a encryption key, in terminal

I can connect to wifi

sudo ifconfig wlan0 up sudo iwconfig wlan0 essid sudo dhclient wlan0

but I don't know how to connect to encrypted wlan so please tell me how to do that, if a wifi password is "abcdef" Thank you.

Solution

  • But this is only working with WEP encryption:

    sudo iwconfig wlan0 essid name key s:abcdef

    sudo dhclient wlan0

    WPA

    You will need to install wpa-supplicant (sudo apt-get install wpasupplicant)

    After you have installed edit the sudo nano /etc/wpa_supplicant.conf

    For example:

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

    And finally you can connect with commands:

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