What do the AirPcap USB Adapters do?

  • All of the AirPcap adapters can operate in a completely passive mode. In this mode, the AirPcap adapter will capture all of the frames that are transferred on a channel, not just frames that are addressed to it. This includes data frames, control frames and management frames.
  • When more than one BSS shares the same channel, the AirPcap adapter will capture the data, control, and management frames from all of the BSSs that are sharing the channel and that are within range of the AirPcap adapter.
  • The AirPcap adapter captures the traffic on a single channel at a time.
  • The channel setting for the AirPcap adapter can be changed using the AirPcap Control Panel, or from the "Advanced Wireless Settings" dialog in Wireshark.
  • Depending on the capabilities of your AirPcap adapter, it can be set to any valid 802.11 channel for packet capture.
  • The AirPcap software can optionally be configured to decrypt WEP-encrypted frames.
  • An arbitrary number of keys can be configured in the driver at the same time, so that the driver can decrypt the traffic of more than one access point at the same time.
  • WPA and WPA2 support is handled by Wireshark.
