  • Open the LX-Terminal and type

   sudo apt-get update && sudo apt-get install raspberrypi* raspi-config

  • Once updated, use the following command to install graphical WiFi connection managerwpa_gui.

               sudo apt-get install wpagui

  • After this try once again search in File manager. If you dint find follow the below steps.
  • Now, edit/etc/network/interfaces file using sudo nano

iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
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
update_config=1

  • 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
  • From now on you can use this nifty graphical WiFi connection manager on Raspberry Pi to configure your WiFi access point settings as shown below.
