Ways crack WiFi password using WPA/WPA2

In previous articles I have explained the steps to crack WiFi password using WEP . But now many ni dah dah tak network using WEP security type, mostly using WPA/WPA2.
So this time I will briefly describe the steps to crack WPA/WPA2. Remember, all this is for learning purposes, it's up how you use it.
Just like before, you need:
Wireless adapters that can do packet injection. I use Alfa AWUS050NH purchased from eBay.
Linux as an operating system, or the BackTrack Live CD.
Compared with WEP, how to crack WPA/WPA2 is much easier because we will be using Reaver. Easy direction, you just have to wait longer to get results. Let us begin:
1. Install Reaver.

apt-get install reaver

2. Get the interface name of your wireless card.

iwconfig
3. On my computer, Alfa AWUS050NH is wlan1. Next, put your wireless card in monitor conditions.

airmon-ng start wlan1

The screen will display the name of your monitor interfaces are usually mon0. Take note of this name.

4. Get BSSID of WiFi that you want to crack.

airodump-ng wlan1

Note: If the above instructions did not work, replace your wireless card interface name (in my case, it is wlan1) with the name of the monitor interface.

5. Start with Reaver crack.

moninterface reaver-i-b BSSID-vv

For example, my command is     reaver-i mon0-b 34:08:04: C9: D0: 04-vv
Let alone this command runs until Reaver managed to get the password you are looking for.Reaver will display the PSK that you can use to get into the network, such as the diagram below:
