 It is recommended that you experiment with your home wireless access point to get familiar with these ideas and techniques. If you do not own a particular access point, please remember to get permission from the owner prior to playing with it. It is recommended that you experiment with your home wireless access point to get familiar with these ideas and techniques.

 It also assumes you know the IP address of various devices on the network.   Chopchop is the most effective way to determine IP addresses since it decrypts packets for you.  In turn, looking at the decrypted packet will give you the IP address and network being used.  You can guess the network and typical IPs based on the manufacturer of the Access Point.  The manufacturer can typically be determined via the MAC address.  Same for DHCP pools which have standard defaults in each brand.  The last method is simply what most people pick as network numbers. It also assumes you know the IP address of various devices on the network.   Chopchop is the most effective way to determine IP addresses since it decrypts packets for you.  In turn, looking at the decrypted packet will give you the IP address and network being used.  You can guess the network and typical IPs based on the manufacturer of the Access Point.  The manufacturer can typically be determined via the MAC address.  Same for DHCP pools which have standard defaults in each brand.  The last method is simply what most people pick as network numbers.
    
-More research is being done on using interactive replay with live packets as an alternate method instead building packets from scratch.  Once this techique is refined, the tutorial will be updated and rereleased.+More research is being done on using interactive replay with live packets as an alternate method instead building packets from scratch.  Once this technique is refined, the tutorial will be updated and re-released.

 +The speed you can achieve depends on the hardware used. By the Access point as well as your hardware.
