 To see if you captured any handshake packets, there are two ways.  Watch the airodump-ng screen for " WPA handshake: 00:14:6C:7E:40:80" in the top right-hand corner.  This means a four-way handshake was successfully captured.  See just above for an example screenshot. To see if you captured any handshake packets, there are two ways.  Watch the airodump-ng screen for " WPA handshake: 00:14:6C:7E:40:80" in the top right-hand corner.  This means a four-way handshake was successfully captured.  See just above for an example screenshot.

-This step is optional.  You only perform this step if you opted to actively speed up the process.  The other constraint is that there must be a wireless client currently associated with the AP.  If there is no wireless client currently associated with the AP, then move onto the next step and be patient.  Needless to say, if a wireless client shows up later, you can backtrack and perform this step.+This step is optional.  If you are patient, you can wait until airodump-ng captures a handshake when one or more clients connect to the AP.  You only perform this step if you opted to actively speed up the process.  The other constraint is that there must be a wireless client currently associated with the AP.  If there is no wireless client currently associated with the AP, then you have to be patient and wait for one to connect to the AP so that a handshake can be captured.  Needless to say, if a wireless client shows up later and airodump-ng did not capture the handshake, you can backtrack and perform this step.
  
 This step sends a message to the wireless client saying that that it is no longer associated with the AP.  The wireless client will then hopefully reauthenticate with the AP.  The reauthentication is what generates the 4-way authentication handshake we are interested in collecting.  This is what we use to break the WPA/WPA2 pre-shared key. This step sends a message to the wireless client saying that that it is no longer associated with the AP.  The wireless client will then hopefully reauthenticate with the AP.  The reauthentication is what generates the 4-way authentication handshake we are interested in collecting.  This is what we use to break the WPA/WPA2 pre-shared key.
