I want to block any body to connect my AP's with out my permission. Is there any solution ? Please help me

There is no way to lock anyone from connecting to an AP as long as it can be seen and also not using a password.

As long as you have a AP that is broadcasting, any body can connect.

If your system is using a password then once they connect,they will need to enter the password to be allowed to do any thing.

If you are not using password, then they can do any thing at any time.
