ok, ran all of the above code, waiting for some ARP's

One question, when I send a fake authentication request, it says

"Authentication successful :-) (AID: 1)"

Whats AID: 1??

EDIT:
Interesting, I was looking at the video made by xploit on cracking WEP Networks
I see he gets arp, requests acks, sends packets, and gets pps's

Right now this is what mine reads

Read 12339 packets (got 0 ARP requests and 0 ACKs), sent 0 packets...(0pps)

What am I doing wrong?

BTW, this ISNT the beta, I didnt mean to post it in here, its a fresh download
