Hi there!

Good demonstration, although after some thinking,

He encrypted the access point with a 128 bit key—made by just keying in random letters and numbers.
At least the Agent should have used a strong PASSPHRASE and demonstrate it. If I were there, I will try to ask if I can also join the fun by being the ONE who will put the PASSPHRASE and see them CRACKING in action. Of course I will use the MAXIMUM allowed PASSPHRASE CHARACTERS to be entered and observe the next few moments while they’re on to CRACKING IT.

128 bit WEP key
Ehem, since it could be down to 104 (after subtracting the semi-random 24 bit number called an Initialization Vector (IV), as part of the key, they haven’t mentioned CRACKING WPA (Wi-Fi Protected Access) standard yet.

3) Use WPA with a strong key WPA is a definite improvement over WEP in providing wireless security. But the version intended for home and SOHO use—WPA-PSK—has a weakness shared by any passphrase security mechanism. The choice of simple, common and short passphrases may allow your WPA-protected WLAN to be quickly compromised via dictionary attack (more info here).
dictionary attack!? OK, what if we really use a stronger PASSPHRASE, any other related tools to do the CRACKING job?
