Unable to capture authentication handshake using airodump-ng

Question

I am using airodump-ng to capture authentication handshake, so I ran airodump for almost 49 minutes and the output appearing as

CH  9 ][ Elapsed: 49 mins ][ 2013-04-14 10:58 ][ fixed channel prism0: -1                                 

 BSSID              PWR RXQ  Beacons    #Data, #/s  CH  MB   ENC  CIPHER AUTH ESSID                        

 04:18:0F:9B:38:99    2 100    28948      457    0   6  54 . WPA2 CCMP   PSK  AndroidAP                    

 BSSID              STATION            PWR   Rate    Lost  Packets  Probes   

But as mentioned on the wiki page of aircrack I should be receiving wpa handshake message.

So please help me where I am doing wrong

set of commands:

# echo 1 | tee /proc/brcm_monitor0  //Switching my wifi in monitor mode
# airmon-ng start prism0            //using airmon-ng to make sure wifi in monitor mode
# airodump-ng prism0                //gives details about neighborhood wifi

 BSSID              STATION            PWR   Rate    Lost  Packets  Probes 

Then I used

# airodump-ng -c 9 --bssid 04:18:0F:9B:38:99 -w psk prism0

which gives the output previously mentioned.

So please let me know where I am wrong because after searching on net I found it won't take much time to gather authentication handshake but I did't get anything after 49 minutes.

my wifi card is: Broadcom Corporation Device [14e4:4365]

Look at the link you mentioned: There is no connected wireless clients -> No handshaking
