How to connect:

  • Connect the 5V 3A power supply for the Raspberry Pi-3.
  • Connect HDMI cable to Raspberry pi-3 for the display purpose.
  • Turn ON the supply for Raspberry Pi.

Setting up the wpa_gui for wifi connectivity for the RPi-3:

  • Open the File manager and go to root folder or type “/ “ in the search option and press Enter.
  • Open the “usr” folder, then open “share” , and then “applications”

iface default inet dhcp


  • Now create a new file/etc/wpa_supplicant/wpa_supplicant.conf with the following contents:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

  • Now use following commands for proper permissions :

    sudo chmod 600 /etc/wpa_supplicant/wpa_supplicant.conf
    sudo adduser pi netdev

  • You can now launchwpa_gui from /usr/share/applications/wpa_gui.desktop (Make a shortcut to desktop using cp /usr/share/applications/wpa_gui.desktop ~/Desktop) as described above.
  • And picture shown below to refer
