 :*The Ubuntu install was by far the easiest part of the process.  I just popped in my newly burnt Ubuntu 8.10 ISO and followed the onscreen instructions.  When it got to the area of where to install I just selected "Guided - use largest free space" and that was it.  Booting into my new Ubuntu system I saw that Ubuntu had recognized my wireless card during install and already installed my drivers successfully solving my initial problem of not having a working wireless connection using linux.

 :*How WPA works
 ::*WPA works similar to WEP but with a few key differences that account for its greater security.  Looking back on the way WEP worked we remember that the 40-bit secret key is just XORed with the 24-bit initialization vector.  This simple process is what allowed people to listen in on networks and then easily reverse the process to gain access to the secret key.  While WPA does employ the same RC4 cipher stream to create the IV section it is no longer just XORed with the secret key.  WPA utilizes a new system know as TKIP or Temporal Key Integrity Output which securely mixes the secret key and the IV, effectively making it harder for a person to listen in on IVs and then obtain the secret key.  This process of mixing the IV with the secret key has now come to be known as dynamic key generation

 :*With the obvious flaws in the WEP system, starting in 1999 a new system, WPA, became available to users.  Later in 2004 WPA was again preceded by WPA2 which offers even greater security.

-:*When clients and access points wish to communicate they send "packets" of information back and forth to one another.  With the rise of the internet and computing in general this process of sending packets back and forth was standardized for ease of use. Today we use the 802.11 standard.  A standard 802.11 packet can be seen [[http://www.geocities.com/backgndtest/wlan_mac_frame.jpg here]]. Besides the standard 802.11 packet, the 802.11 standard utilizes different frames that are placed in a packet to give it a specific purpose.  Below is a list of the frames that will be used through out AJ and Is testing (Please note that this is not a complete list of all 802.11 frames but only a list of the frames that we encountered).
