You have a few options

  • Check for a feature called MAC filtering. You can block access by MAC address. I'd suggest doing the opposite though and only allowing certain MACs. This way, MAC spoofing won't work, unless they spoof one of your device MACs (which would cause conflicts and probably refuse connection anyways).

  • Check for an access control feature. It works similar to MAC filtering but you can specify which parts of the network are blocked, and optionally log all attempts:

  • Physically unplug the network cable
