Hi,
I am currently playing with a Stadia Controller connected to my Iphone, my Laptop or a Google TV.
My son (with his own account in my Google Family) can't connect the same controller.
When we try to associate the Controller with the combination of keys it never connects. His device is on the same WiFi than the controller.
Any idea ?
Is your son trying to connect the controller to the same devices (iPhone, laptop, Google TV) that you've been using?
Have you gone through these steps to add your son's account to the Google TV device?

Once the account is added, you should be able to just power on the controller, connect with the linking code, and then choose which account to play with. My wife and I are able to switch between our Stadia accounts on the same controller and Google TV in this way.
