If you want to listen to network traffic and to capture network traffic, your network adapter needs to be in Monitor mode. Start the wireless interface in monitor mode Run aircrack-ng to crack key using the IVs collected.Start aireplay-ng in ARP request replay mode to inject packets.Use aireplay-ng to do a fake authentication with the target access point.Start airodump-ng on AP channel with a bssid filter to collect the new unique IVs.Start airodump-ng to discover all the available networks and find your target.

Start the wireless interface in monitor mode.

Here are the basic steps we will be going through:

Ok, we have all the hardware and software ready, now it is time to explain how WEP cracking works. They both should result in the ' Injection is working!' message. Try executing the following two commands in yourВ terminal window: Use the injection test to confirm your card can inject prior to proceeding. If the network interface is set correctly, it should say Monitor mode. The print screen below shows you what you want to see in your iwconfig screen. You can find the name of your network adapter by executing the iwconfig command. ItВ would be rausb0 if you worked with the TP-LINK 321. Wlan0 (and also wifi0) is the name of your Intel 3945 network adapter. If it is not, try executing the following command:

If you loaded your driver module correctly, your network adapter might already be in Monitor mode.

One of the assumptions in this article is that your network interface drivers need to be patched for monitor mode and packet injection. Does my network adapter driver work correctly? The Intel adapter is referenced as wlan0 ( wifi0), and the TP-LINK adapter is referenced as rausb0. We have tested WEP cracking with two network adapters: Intel PRO/Wireless 3945ABG with the ipwraw-ng-2.3.4 driverВ and alternatively TP-LINK TL-WN321G network adapter dongle with the rt73-k2wrlz-3.0.1. The reason is that WEP cracking relies on ARP packets and if there are no active clients then there will never be any ARP request packets.Д®nsure that all of the above assumptions are true, otherwise theВ examples that follow will not work.

There is at least one wireless client connected to the network and active.

The wireless card strength is typically less than the access pointВ strength, so you have to be physically close enough for your transmitted packets to reach and be received by the access point. Remember that just because you can receive packets from the wireless access point does not mean you will be able to transmit packets to the access point.

You are physically close enough to the access point to send and receive packets.

(Of course, you can use some other adapter as well, Intel and TP-LINK is what we used.)

Software and hardware: Ubuntu, Intel PRO/Wireless 3945ABG with the ipwraw-ng-2.3.4 driver (or alternatively TP-LINK TL-WN321G network adapter with the rt73-k2wrlz-3.0.1.

Other tutorials on the web are based onВ differentВ assumptions. Note, the assumptions listed below are specific to this tutorial. Here is a list of assumptions that you need to meet in order to be able to discover a WEP key from network traffic. What doВ I need toВ discover a wireless network WEP key? Now we can proceed to demonstrating how toВ crack WEP encryption. How to crack WEP with Intel PRO/Wireless 3945ABG Before you proceed to WEP cracking, read our first page of this 'tutorial' which can provide an idea about setting your computer and also about the legality of WEP cracking. Setting up your equipment so that it does what it needs to do can take weeks (depends on what you have and what you already know). Cracking WEP itself is relatively easy and can take anywhere from as little as aВ few minutes to a few hours (depends on the amount of network traffic, connection quality, etc.).
