Could it be that you are looking for 802.11n(MCS) data frames? Because by default, carl9170's monitor mode only catches the legacy 802.11a/b/g frames. If this is the case, then try setting the right channel mode (HT20/HT40+/HT40-) when selecting the channel. i.e.: # iw dev wlanX set channel Y HT20 # iw dev wlanX set channel Y HT40+ I hope this helps. Otherwise, you could try: # iw dev wlanX set monitor [...] fcsfail and see if you are picking up frames this way. This should work, but you will be picking up mostly damaged stuff, so some extra frame processing will be needed to filter out the noise.
