general, cracking WEP-encrypted wireless network speed is even more.
2. Change the wireless NIC Driver for data monitoring:
Similar to the previous intrusion into wireless encryption WEP, we first need to update our wireless NIC Driver, because by default, although the wireless Nic can communicate wirelessly, however, it is not competent for listening. The procedure is as follows.
Step 1: The notebook I use is IBM T400. By default, his wireless network adapter is the
network card uses Atheros v4.2.1. The card must use the Atheros AR5001, AR5002, AR5004, AR5005 or AR5006 chipset. The following table can be used for NICs, in this experiment, we use Netgear's memory M wireless network adapter (model: wgw.t ).
(1) install the packet capture wireless NIC driver on the STA3 notebook. Insert a wireless network card. The window shown in 11 is displayed. Select "No, temporarily
without stopping communication. On this basis, another computer is used to steal encrypted data packets and crack them. The specific device is as follows.
AP: D-LinkDWL-2000AP + A, responsible for setting WPA encryption information.
Wireless Client: notebook + D-Link DWL-G122Wireless Network CardTo ensure continuous WPA data communication.
Listening/cracking machine: Laptop + NetGear wagelist V2 wireless network card, used to capture and log onto the 'handler' session and CrackKEY.

Click "restart vro" under "System Tools" to restart the vro.5. Download Software for cracking WEP and WPA keysTo download the software used to crack the key from the Internet,
, you should disable the OS option in the Bios, and select the corresponding video card based on the installed video card drive model in the Bios. The system recognizes integrated graphics cards by default.
2. Intel's Wired and Atheros Wireless NICs cannot be loaded automatically.An Intel wired network card must be installed with a Linux driver of the corresponding model. Because the drive path is loaded by the kernel in the form of a module, the Linu

To meet strong market demand, many WLAN, Wi-max and mobile communications companies have provided (or are planning to provide) solutions based on MIMO technology. MIMO has a number of functions, such as transmission beamforming (transmit beamforming)/maximum ratio combination (maximal Ratio COMBINING;MRC), spatial multi-work (spatia

Debian-Debian-the Linux release technology-which is used to drive wireless NICs. For more information, see the following. In the past, FC6 was used because the NIC could not be driven. Later, debian tried to load the driver under win, But it crashed every time. Ubuntu can be used after the NIC is plugged in. The NIC is tp-link WN310g. I accidentally saw someone on the internet saying I could use the native drive of Atheros. I tried it on the internet

Step 2: select the corresponding Nic and enter the serial number before the wireless Nic. For example, the ID is 13.

The CPU does not contain the switch chip. In addition, an adm6996 is installed, and the wireless module uses the atheros.

(1) Name of the Network Interface
There are no naming rules, but the definition of network interface names is generally meaningful. For example:
Eth0: Abbreviation of Ethernet, which is generally used for Ethernet interfaces.
Wifi0: Wi-Fi is a wireless LAN, so wifi0 generally refers to a wireless network interface.
ATH0: Short for atheros, generally refers to the wireless network interface contained in the atheros
