If You Are Having An Error

Once you have completed the above steps, a configuration file with the newly created connection name is created under /etc/NetworkManager/system-connections directory. We will now edit this configuration file. Open Terminal and run the following command to edit the configuration file:

gksu gedit /etc/NetworkManager/system-connections/wifi-connection-name

Restart the system and enable WIFI from Network Manager icon on the Ubuntu panel bar. It will automatically connect to the newly created WiFi hotspot. If it is not connected automatically, select “Connect to Hidden Wi-Fi Network” and select the newly created WiFi hotspot from the drop-down list.
