Changing wifi

[thomchas]

I have built a scoreboard for my brother in law and want to be able to change the ssid and password that he uses at his house. Right now I have it connecting to my internet connection to set it up and configure it. Is there a way for me to configure it for his network before I give it to him without being there. I have tried changing ssid and password using rasp-pi config, but after making the change and saving it reverts back to my ssid and password I guess because it can’t find his network. So is there a simple solution for me to be able set his network up on my end before I give it to him?
