Step-by-Step Guide

• A 'wpa_supplicant' file must contain the necessary credentials to connect to your network.

  Target (Linux)

  vi /etc/wpa_supplicant.conf

  CODE

• Ensure that this file reflects the following contents (replace NETWORKNAME and NETWORKPASSWORD to the corresponding credentials for your target network): 

  /etc/wpa_supplicant.conf

  ctrl_interface=/var/run/wpa_supplicant
  ctrl_interface_group=0
  update_config=1
  
  network={
          ssid="NETWORKNAME"
          key_mgmt=WPA-PSK
          psk="NETWORKPASSWORD"
  }

  CODE
  

  The vi text editor begins in "Command Mode" and you must first hit the 'i' key in order to enter "Insert Mode". Using the arrow keys to navigate, make the necessary changes and then hit ESC to go back to "Command mode". Now enter ":wq" to write the file and quit.

Setup the Interface

• Load the credentials from the previous step:

  Target (Linux)

  wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf

  CODE

• Launch the WiFi client 

  Target (Linux)

  udhcpc -i wlan0

  CODE
• Wait until you obtain an IP address.

• Test your connection 

  Target (Linux)

  ping google.com -c 10
