airmon-ng

make sure your wifi interface is capable of packet capture and can go into promiscuous mode.

Trist007,
Out with of those 4 that you mentioned, which one is easiest to use? also, how do I know if my Wi-Fi interface is capable of packet capture and how do I going to promiscuous mode?

This might help http://www.aircrack-ng.org/doku.php?id=cracking_wpa

You can use MAC-address filtering. Since every machine has it's unique MAC-address, filtering allows only trusted machines to connect to your network, no matter secure your password or not.

If you really want your network to be both wireless-accessible and secure, you need to use [Open]VPN ... with digital certificates.

This way, if someone else in the coffee shop breaks the WPA encryption on what you're sending, Eve only sees a strongly-encrypted data stream underneath.

With certificates (and TLS-protection, in OpenVPN ...), there is no "password a.k.a. pre-shared key (PSK)" to break ... period. There are only one-of-a-kind digital keys, thousands of bits long, which on your computer should be further protected by being encrypted. Each and every certificate is unique, and can be individually (and, instantly ...) revoked without affecting any of the others.

WPA, et al, is merely designed to make it "moderately difficult" to listen-in on a wireless conversation. It is not, nor was it intended to be, "strong" security.
