I have a teenage at home and would like to know if I can turn off WIFI on his laptop and leave it on on other computers ?
A more complicated solution, though probably more appropriate is to go into your wireless router's settings and enable MAC address filtering. Every device has a hardware MAC address. Using this feature, you can add all of your allowed devices to the list, including the teenager's computer. When you wish to block the teenager's access, you remove that MAC address from the allowed list.
You'll need to determine the MAC address for every device and you'll need to secure your router.
Some routers include additional features to restrict and allow access. You may also want to look into Parental Controls that provide the ability to set limits on Internet access on a per user basis.
