Hi @Robin_se,

Thank you for reporting your issue to our community.

If Parental Control is not working on the Router, please review the following troubleshooting steps based on different scenarios.
1. Parental Control delayed for one hour?
   It is usually caused by the Daylight Saving time. Please open the Tether APP, and then go to Tools > System > System time to check the Daylight Saving Time and time zone settings.
2. Blocked device not working at all? Blocked device still having Internet access
   1) Most mobile devices have randomized mac addresses enabled by default. Please check the current mac address of the client device and disable randomized mac address.
   2) You could also check if the client device is using VPN to avoid the parental control, If so, disable VPN for testing.
3. Parental Control blocking websites by mistake?
   The HomeShield Parental Control keeps a record of daily blocked history, if any websites are blocked by mistake, please enter the parental control profile -> Block History -> Find the Site and "ADD TO APPROVED WEBSITES".
4. Blocked websites not working? Client devices can still access sites that are blocked?
    1) Enter the parental control profile > Content Filter, make sure the correct category is selected.
    2) Add the website manually into the "Blocked Websites" section.
