Blocking or asking for access to get onto home network?

[unhandy]

I get a notification when a new device logs onto our home internet.  My question: is there a way to block additional devices from logging on to the network OR having them ask permission to get on internet? 

My issue is that my teenage sons are tech savvy and change device names to get onto the network and work around the time constraints/parental controls.  Any advice on how to stop limit their work around?

You're the parent, right? Then read them the riot act. Either they follow the rules or they get their devices locked down or taken away.
