I wonder if I'm doing something bad, trying to find out a WPA key
- my card supports mode monitoring
- its name is wlan0

Some friend told me the PWR value should be positive (and not negative)

Check:

1- main screen


2- cowpatty


3- aircrack


I clearly see that the "handshake" could not be made. May I know why?
- The time I tried to do this? 0:02am
- No one connected to AP?
- something else?

Thanks a lot in advance and hope anyone can guide me to correct these mistakes...
