What should I do if my router has MAC filtering or access control enabled and my devices can't connect through the extender?

When devices connect through the extender, the router sees a translated MAC address, which causes MAC filter or ACL settings to block those devices from getting an IP address. To fix this, log into your router and disable the MAC filter or ACL, then run the Quick Setup on the extender and connect all devices to the extended network. Finally, add all the Online Devices' MAC addresses to your router's MAC filter table, then re-enable the router's MAC filter or ACL.
