MT7610U weird Active monitor mode behaviour on Raspberry Pi

Open LightMoon opened this issue 1 year ago • 5 comments

Hi! I am facing a strange issue with AWUS036ACHM - Chipset MT7610U on Kali Linux RasPi 5. The card stops working and throwing ioctl(SIOCGIFINDEX) failed: No such device error if you run Aireplay-ng while having Airodump-ng running.

Error on shown on airodump-ng

read failed: Network is down

ioctl(SIOCGIFINDEX) failed: No such device                                                           
Can't reopen wlan1mon

NB: this attack is more effective when targeting
a connected wireless client (-c <client's mac>).

Good to note, I did ran airmon-ng check kill prior to eliminate processes interference, also replaced the driver to the latest, however, none has stopped the issue.

uname -a Linux kali-raspberry-pi5 6.1.64-v8+ #1 SMP PREEMPT Sun Dec 3 11:34:54 UTC 2023 aarch64 GNU/Linux It seems the issue is related to arm CPUs as it can be reproduced on the latest Raspbian OS; although the card on Kali (Intel) works fine. I am not sure but if someone could confirm this issue could be related to the bug - https://bugzilla.kernel.org/show_bug.cgi?id=217465 would be great. I would appreciate any tips you could give me in getting the card to the usable stage.

Steps for reproducing error in summary:

  • Kali Linux for RasPi => apt update & apt upgrade -y
  • replace the existing MT7601U driver with the latest version from the Linux kernel repository and the reboot once.
  • airmon-ng check kill
  • airmon-ng start wlanX ( x could be different to your environment )
  • airodump-ng --channel 11 --bssid xx:xx:xx:xx:xx:xx wlanXmon
  • aireplay-ng -0 10 -a xx:xx:xx:xx:xx:xx wlanXmon
