Hi I would like to ask if I can block a user who connects to our network and generates high usage of internet.
The problem is every time he clones his MAC address.
PS ...( WITH OUT SETTING A PASSWORD ON THE APs AND WITH OUT SWITCHING THEM OFF)
Only way to prevent it is to do exactly what you mentioned you don't want to do and that's set a password or eap security. Layer 2 hacks have been around for ages. Very hard to defend unless you lift security requirements.
