unable to configure parental controls

I do not have the answer to your question but I am subscribing to your discussion.  I was never able to configure the parental controls on my previous Netgear Router and I eventually gave up.  I was able to set a general content approval level but that was all I could do.   I have recently purchased a new router (an R7000 Nighthawk) and I am going to make a renewed attempt at setting up parental controls.  Thanks for starting the discussion.  Let's hope we get a clear and understandable response.  Sincerely,
