BT Access Control
Use Access Control to set times when specific devices will be prevented from connecting to the internet. This can be handy, for example, if you’d like to cut down on the amount of time your children are online.
This means the Hub will block all incoming and outgoing traffic to specific devices between the hours of your choice.
What's the point of this if the older child of the family just comes down during the early hours and just Hard Reset's the router?. Is there no other way as i don't want them using it beyond 1am!.
