How to prevent the router from working properly?

My child is addicted to the wifi network and plays games with his mobile phone or tablet. I want to mute the wifi signal and prevent it from accessing the internet. How can I stop?


Around me, I often see many people complaining that children's self-control is weaker and more rebellious, so it is necessary to take drastic measures. As you said, it is a very good way to cut off the wifi network so that it can't work normally. As for how to block wifi signal, you can buy a professional Desktop WiFi Jammer in our store.
