Helpful WiFi topics
The Security menu allows you to view settings to control access to your home network, including these options:
- Firewall
- MAC Filter
- Parental Control - see next section for details
- Scheduler Rule
- Certificates
Parental Control allows you to define users within your household and set limits on when they have access to WiFi.
1. Start by using the slider button at the top to enable Parental Control. Blue means it is enabled; gray means it is disabled.
2. From here you can click 'Add more profiles' to create new user profiles for your household members. You can also turn existing profiles on or off with the slider, or select the arrow at the bottom to edit controls you have already created.
3. To create a new profile, type the name of the user into the box on the left, and make sure the slider is blue to indicate 'Active.' Under 'Profile Device List,' you will be able to check and modify the list of devices that person uses. Then click 'Next' to set up a schedule.
4. Modify an existing schedule, or click 'Add New Schedule.' Then you can set hours and days that the user will be blocked from online access. When you are finished, click 'Save.'
Repeat these steps for each user you want to manage.
