Uhm, do you need to access the raw 802.11n frames or just “baked” 802.3
frames?

raw 802.11n frames…

I don’t know if there are native wifi drivers for 802.11n chipsets that
export the original 802.11n frames. From what I’ve seen, even the native
wifi drivers for 802.11n chipsets export “cooked” 802.11 frames, i.e.
removing some important fields in the beacon and/or data frames (if I
remember well for example a QoS+DATA frame is transformed into a DATA frame
modifying the FC field and removing the QoS header).

The company I work for has a solution for 802.11n sniffing, it uses
customized hardware

Please contact me in pvt if you need more information
