My problem is with an RE200 range extendere but it is not available in the new thread model list.
My network has an Archer AC5400 router and AC750 RE200 range extender.
When a device that is blocked by parental controls on the router connects throught the range extender, it is allowed internet access.
This is a big flaw. It seems no one in the wifi router development industry has any clue on how to design parental controls.
I have not found one yet that works as a parent would use it.
