The SBG6400 Parental Controls feature provides the ability to block or allow Internet access during a specified Time of Day. The Internet can be blocked or allowed for certain times of the day, certain days of the week, or all times. Access permissions can be assigned to all devices on the network, or a specific device (e.g. computer, gaming console, tablet). By default, Parental Controls is disabled, which allows all Internet access to all devices. This document describes how to block one device from accessing the Internet for a specified Time of Day.
This document contains the following sections:
