I have Family Base time restrictions set up for my step-son, but he is clearly using the internet during the restricted hours for Facebook chat & Skype. He does not have access to wifi as we unplug and put the router and modem in the safe at night. I have checked and rechecked the settings. I have removed them and redone them. I have had my husband check them and we can't find anything wrong, yet he is on the internet every night. How is this possible and what can I do?
