Very useful videos, (link)

[TrialAndError]

Here is a collection of useful educational videos covering numerous tools and techniques relevant to the security domain. This is well worth a look...and bookmarking!!!

I found the the RC4 Encryption section especially useful...it gives a really good overview of how WEP encryption actually works, and therefore makes sense of the techniques employed when using the Aircrack suite. They're adding new videos all the time covering tons of useful apps, (such as Wireshark, Nmap, Netcat and more), as well as an overview into techniques such as Sniffing, Packet Injection and so so much more...as I say, it's well worth a look
