It takes about 5-6 hours if the password is weak a high signal of the WiFi network you are going to hack and you have sometimes 10-12 for more complicated passwords and if the WiFi signal of the Network is weak .The time taken also changes if the WiFi network you are going to hack has many other clients already accessing it .

{ get the 30 day trial or use the free full version available on net from other sites.) (i recomment the 30 day trial because it will be the latest ) after it expires y can always go to other means.
You will use this tool for capturing the packets sent and recieved through the Access Point you are going to hack .The more packets you capture the better chances of cracking the password .You will need more than 1,00,000 minium packets to
crack the password .The packets will be captured in the .ncp format .You will use this tool to convert the .ncp to .cap .
NOT MANY NETWORK CARDS ARE SUPPORTED SO PLEASE CHECK YOUR NETWORK ADAPTER IN DEVICE MANAGER. IF it is not supported then there is no other option then to use backtrack with extra hardware.
