I’m currently looking for information regarding the possibility to use the BBB as an wifi packet-sniffering device.
When carried out with the next composition, the error of came out.
OS : Ubuntu 12.04
Sniffering soft : Wireshark
USB wifi chipset : rt8070
error message :
The capabilities of the capture device “wlan0” could not be obtained (That device doesn’t support monitor mode).
Please check to make sure you have sufficient permissions, and that
you have the proper interface or pipe specified.
Try using airmon-ng, as suggested by CaptureSetup/WLAN in the Wireshark Wiki.
In the past, with the same composition on notebook PC I could capture packets.
What can I do for sniffering packets by BBB?
If that doesn’t work, my students did a nice project[1] that runs tcpdump on the bone to collect data and passes the data to WireShark (running on the host) to display the data.

When I reinstall Ubuntu “13.10”, I can capture packets.
Probably, some drivers needed for packet-sniffering were contained in not 12.04 package but 13.10 package.
