For an explanation of ARP, see this PC Magazine page or Wikipedia. The purpose of this step is to start aireplay-ng in a mode which listens for ARP requests then reinjects them back into the network. Step 2 - Test Wireless Device Packet Injection This will give you the frequency for each channel. To match the frequency to the channel, check out: It is important to confirm all this information prior to proceeding, otherwise the following steps will not work properly.

Please note that only the madwifi-ng drivers show the MAC address of your wireless card, the other drivers do not do this. In the response above, you can see that ath0 is in monitor mode, on the 2.452GHz frequency which is channel 9 and the Access Point shows the MAC address of your wireless card.

Tx excessive retries:0 Invalid misc:0 Missed beacon:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Link Quality=0/94 Signal level=-95 dBm Noise level=-95 dBm

You will notice that вЂњath0вЂќ is reported above as being put into monitor mode. Examples: вЂњwlan0вЂќ or вЂњrausb0вЂќ.ДЄth0 Atheros madwifi-ng VAP (parent: wifi0) (monitor mode enabled) For other drivers, use the wireless interface name. This is because the madwifi-ng drivers are being used. Note: In this command we use вЂњwifi0вЂќ instead of our wireless interface of вЂњath0вЂќ. You must have your wireless card locked to the AP channel for the following steps in this tutorial to work correctly. Substitute the channel number that your AP runs on for вЂњ9вЂќ in the command above. Now, enter the following command to start the wireless card on channel 9 in monitor mode: When you are finished, run вЂњiwconfigвЂќ to ensure there are none left. If there are any remaining athX interfaces, then stop each one. (Note: this procedure is different for non-Atheros cards.)ДЄth0 Atheros madwifi-ng VAP (parent: wifi0) (VAP destroyed)Д®nter вЂњiwconfigвЂќ to ensure there are no other athX interfaces. As well, only (there are some rare exceptions) monitor mode allows you to inject packets. By hearing every packet, we can later select some for injection. Normally your card will only вЂњhearвЂќ packets addressed to you. Monitor mode is mode whereby your card can listen to every packet in the air. The purpose of this step is to put your card into what is called monitor mode. Additional troubleshooting ideas and tips are especially welcome. Please send me any constructive feedback, positive or negative. 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.

Although this tutorial does not cover all the steps, it does attempt to provide much more detailed examples of the steps to actually crack a WEP key plus explain the reason and background of each step. This 'What is an ARP?' section provides the details.ДЇor a start to finish newbie guide, see the Linux Newbie Guide. It is important to understand what an ARP packet is. In turn, aircrack-ng uses the new unique IVs to crack the WEP key. The basic concept behind this tutorial is using aireplay-ng replay an ARP packet to generate new unique IVs. It assumes you have a working wireless card with drivers already patched for injection. It is intended to build your basic skills and get you familiar with the concepts. This tutorial walks you though a very simple case to crack a WEP key.
