A user can block a device from accessing the network using the Time and Schedule feature of the dlinkrouter.local interface. While maintaining the Schedule, a user has to make sure that the Time zone assigned to the router is appropriate and correct. To add a timetable for specific devices, click on the Add rule button and configure the duration according to your requirements. Any fault in the Time-zone may bring failure in the Schedule feature of the router. You can configure the Time-zone of a Dlink router using its web management interface.
