I am trying to stop my son from accessing our internet/wifi from any other device than our PC.

In the hope that I can regulate the amount of time he is spending on it.

Please can someone help as I need to sort this out asap

Many thanks

Wifi router/wireless access point  is having mac address filtering option.. allow only the needed mac address using mac address filtering.. Check Wifi router/wireless access point manual for wireless filtering configurations..
