Automatically connect Ubuntu to a specific WiFi at startup

Question

I am working with Ubuntu 16.04. I want the system to connect to a particular WiFi network automatically when it boots; it can be a new connection which the system has not connected to earlier. For example: SSID = wireless; password = abcde

I have tried suggestions from this question but they did not work for me (the system kept connecting to one of the previously known networks).

Please help. Thanks.

You can edit the interface file /etc/network/interfaces and add the informations about the WiFi you want to connect to :

network={
ssid="testing"
psk="testingPassword"
}
