Nah. You're going about this all wrong.

You're trying to be too competent with him. Set up all of the routers, on all of the time. Explain that you thought the devices he left you would suck up the bad wifi, and that you are pretty sure you saw a website where that was the case and you will not be turning them off because you are really concerned for his health, and he is not thinking straight.

More networks, not fewer is the key.
