 The point of cracking is to generate data.  You can generate data in Section 4, but sometimes there are no clients connected to wifi, but the AP is still sending out data.  In this case, you will want to capture the data that the AP is sending out, and use it to determine a valid XOR keystream (basically a file which allows you to create a packet with out knowing the key).   The two attacks for this are "​fragmentation"​ and "​chop-chop"​. ​ Fragmentation is quickest, but you have to have a good connection to the AP (be close to the AP), and it doesn'​t work with all cards. ​ Chop-chop usually works with all cards, but it doesn'​t always work on every AP. The point of cracking is to generate data.  You can generate data in Section 4, but sometimes there are no clients connected to wifi, but the AP is still sending out data.  In this case, you will want to capture the data that the AP is sending out, and use it to determine a valid XOR keystream (basically a file which allows you to create a packet with out knowing the key).   The two attacks for this are "​fragmentation"​ and "​chop-chop"​. ​ Fragmentation is quickest, but you have to have a good connection to the AP (be close to the AP), and it doesn'​t work with all cards. ​ Chop-chop usually works with all cards, but it doesn'​t always work on every AP.
