Internet block devices

[Akhearix]

I am attempting to restrict night time access to my teen, however even with creating a profile on Helix, putting all her devices in said profile, this brat finds a way to reinstate her connectivity. 

So either she's finding a method to by-pass the "Mac" filtering, or Helix is unable to perform the task. She has succeeded in staying connected on three separate Helix Hubs, two of which were the original black Helix hubs, and one white.
