hey,
when using airodump-ng to monitor packets I almost see no packet transfer with my usb cards in monitor mode.
I have 2 internal wifi and 2 external atheros usb wifi cards to test.
airodump -c 13 wlanX
Card Beacons #Data internal Broadcom 1000 7159 (ok) internal Intel Wireless-N 1000 7443 (ok) USB TP-Link TL-WN821N V1 (AR9170) 1510 7 (bad) USB TP-Link TL-WN821N V2 (AR9170) 1574 8 (bad)
However airodump detects lost packets between AP and Client of the AR9170 cards (the amount isn't equal to the broadcom's detected loss amount).
What I've tested so far:
- Tested in: Kali 1.1 (problem), Kali 2.0 (problem), Backtrack 5 R3 (everything works as it should)
- wps handshake detecting: Kali - only detected by broadcom, Backtrack - all 3 cards detect handshake
- Carl9170 drivers/firmware: Kali - 1.9.7/1.9.6, Backtrack - 1.9.4/1.9.4
- Aircrack versions: Kali - 1.2, Backtrack - 1.1
- Copied Aircrack from Backtrack to Kali: Same problem
- Copied Carl9170 firmware (not the driver) from Backtrack to Kali: Same problem
- Captured .cap file: almost empty with AR9170 cards
- Occurs on each channel or AP
- dmesg sometimes (less than once every 100 seconds) outputs for AR9170: invalid plcp cck rate (0). or frame tail is clipped.
- no distance problems (1m away, 4m away, 10m away)
- tested on two notebooks
I'm not sure if this is a aircrack problem... any help would be good. Perhaps someone had the same problems.
