  6. Choose a channel and device to capture packets from.
  7. Capture raw 802.11 frames from the chosen particular channel and device using airodump-ng. This tools is particularly suitable for collecting WEP initialization vectors so that they can be used for cracking with aircrack-ng. Specify the channel number with the -c parameter, the file name with the -w parameter, the device with the -d parameter, and the interface name at the end of the command, e.g.,

    airodump-ng -c11 -w capture -d E8:65:…:FA:F3 wlan0mon
