This starts packet capture, but for cracking the wireless network, ARP Packets have to

be specially captured, for which, the following command has to be typed:

aireplay-ng --arpreplay -e ESSID mon0.

This starts intercepting ARP Packets. Higher the captured ARP Packet, better is the

chance of cracking wireless network.

7- DeAuth Packet: This is also known as the ‘denial of service’ attack, as it disconnects a

client from the access point till the time a packet is sent. The purpose of sending DeAuth
packet is to disconnect the client and force them to connect again so that the ARP

Packet can be captured.

Command for sending Deauth packet:

aireplay-ng --deauth 0 -e ABC (ESSID Name) mon0

Here,

ABC = ESSID Name of victim network
Mon0= interface name

Make sure you run the DeAuth Packet on the same channel as the wireless network.

To test this you can connect a mobile to the wireless network and send DeAuth packets.
The PWR value of that wireless network goes down and when this reaches ‘0’ the
mobile gets disconnected.
