Subject:ar9280+802.11na+ath9k+kismet don't capture data packets
Date:13:09:21 22/04/2011

Hello!

The platform uses D-link DIR-825 Atheros AR7161, with two AR9280(802.11bgn and 802.11an)
kismet-2010-07-R1 is installed to OpenWrt Backfire Trunk. Used driver at9k of compat-wireless-2011-04-19.
For tests I use D-Link Dir-825 AP and D-Link DWA-160. Connection speed is 300 Mbps at 36 channel.
Kismet captures PHY and Control packets, and don't capture the data packets.

After that ifconfig issued:

Is it possible to capture 802.11n data packets using Kismet?
