When you set the time from 00:00:00-14:30:00 and it’s not blocking the device as expected, the issue might be related to how the router interprets the time ranges. Setting it from 00:00:00 might create confusion in the router’s system because it’s often interpreted as the start of the day (midnight). I had conversation about that some time ago with the metro by tmobile , they helped me to understand this problem and solve it of course.
