I'm glad that you're reading through the book that I had mentioned. I would treat the AP that is "broadcasting two mac addresses" as two seperate AP's. So, try to capture a different handshake for each one. I hate to be negative, but I want you to keep in mind that you're probably not going to crack a WPA protected AP(unless this AP is 'reaverable'). Does this mean you shouldn't try? Absolutely not... Give it a shot. You never know. What I recommend for you:

-Set up your own AP using WPA

-Set the password to a common word. For example, dog, cat, television, rooftop. Any of these will do.

-Use the tactics you've learned from the reading to capture and crack a handshake using the rockyou.txt dictionary. This dictionary comes with backtrack and can be found elsewhere online.

-Don't forget to change the authentication password for your AP back normal.

If you are unable to complete the previous tasks then you may be doing something wrong. If you are successful then you know that your doing it right. After success you can take your skills on the road. Good luck and get back to me.
