In the following case we will block the Internet by time in our router tp-link, this way all the users that we place within a group of host will not be able to access the Internet navigation, however they will be able to communicate within the LAN network for file and printer sharing.
The schedule is fully customizable, you can choose the hours to enable the blocking rule, in this way everything will be automated once you have created the profile within your router.
