Add WPA Supplicant Configuration File

Follow the steps below to create the wpa_supplicant.conf file:
  1. Manually creating the wpa_supplicant.conf configuration file or use /etc/wpa_supplicant.conf.
  2. Add the following content to the configuration file:
    ctrl_interface=/var/run/wpa_supplicant
update_config=1
    Note: This allows wpa_supplicant to overwrite configuration files after modifying the configuration. For example, add new network statement blocks through wpa_cli tool, write configuration to wpa_gui, change password, etc.
