My son has worked he can change the MAC address to bypass parental controls. This means my deco is essentially useless - the whole reason I spent all that money on this system was to control his screen time. There's no whitelist, and there is no manual

approval of new devices joining the network. I have to manually block each new MAC address when he connects. My only option is to change the password, reset the connections for 20+ devices and smart home devices, and hope that his siblings don't tell him the new password. This is a terrible solution, and I can see that there have been people raising this as a problem in this forum for years now.
