-There has been a lot of discussion over time of how to use a wireless client workstation to generate packets to crack   WEP instead of the wireless access point itself. This tutorial describes four approaches with examples of how to do this.

This tutorial describes four approaches with examples of how to do this. The examples provided are from real working equipment, not theory. ​ Each was used in real life and successfully cracked the WEP keys.
  
 The basic idea is to have the wireless client workstation generate data packets with IVs which we can use to crack the WEP key. Normally we have the access point itself generate the data packets with IVs.  So why would you need to leverage a wireless client workstation instead of the access point? Here are just a few of the reasons: The basic idea is to have the wireless client workstation generate data packets with IVs which we can use to crack the WEP key.

-You run the following command and select a packet which is a decent size.  It has to be larger then the ARP packet we want to create. So pick something like 86 or more bytes. As well we need to determine the IP address of the wireless workstation we are targeting. So pick a packet with a source or destination MAC address of the workstation. The reason for this is will later use tcpdump to look at the decrypted packet and obtain the IP address.+You run the following command and select a packet which is a decent size.  It has to be larger then the ARP packet we want to create.
