Summary0003014: Regression in monitor mode of some Ralink cards with Linux 4.3 of Kali 2016.1

Have just installed the latest Kali 2.0 2016 rolling release. I have a ralink adapter with a rt2870 chip which uses the rt2800usb firmware. When trying to use anything with monitor mode with this chipset i cannot see associated clients. There is a issue with rt2800usb firmware. I have confirmed it. My toughbook has just Kali 2.0 installed and updated but not to the rolling release. It works and can see Associated clients. However on the newest kernel that comes with the rolling release it does not work. I have tried multiple things to try and get it to work and it wont. It can see clients for instance in airodump-ng but it cannot them being associated with the AP. Even with a device sitting right next to my AP it cant see them, however if i go to my toughbook that has the older kernel everything works just fine,

Steps To Reproduce

I can reproduce it with anything that has to do with monitor mode with the ralink rt2870 chipset on Newest kernel on Kali 2.0 2016 rolling release

Very similar problem here.

USB wireless adaptor : Alfa AWUS052NH (Ralink RT3572 chipset, rt2800usb/rt2x00usb modules)

Steps to reproduce :

  1. airmon-ng start wlan0
  2. airbase-ng -e "My_AP" -c 11 wlan0mon

Tap device at0 is created, the access point is visible from neighbouring clients, but cannot be associated with them. airbase-ng doesn't display any output when a client tries to connect.

I tried on 3 different machines, and also tried to disable ipv6 completely, without success.

On Sana (Kali 2.0), the AP can be associated without problem.

Seems like a kernel-related problem, I don't know if you Kali folks can do anything about this issue... Thanks anyway.

Found the same problem with the PCI version of these Ralink modules :

  • device : "Ralink corp. RT3090 Wireless 802.11n 1T/1R PCIe"
  • modules : rt2800pci, rt2x00pci, etc.
    Access point works on Sana/2.0, but not on current rolling-release.

I have decided to downgrade to "4.0.0-kali1-amd64 0000001 SMP Debian 4.0.4-1+kali2 (2015-06-03) x86_64 GNU/Linux" This is the kernel version I am using as noted above by two_factor and everything works great now. Before downgrading I used many different usb,pci, and pcie ralink based wifi adpaters and it seems any of them that use the rt2800usb, rt2800pci or anything ralink will not see associated clients at all. It would seem this is definately a kernel issue with the supplied ralink drivers and firmware. Not sure if this help but this is current output from lshw.

I tried to find other reports of similar problems but was unable to find anything relevant.

It would be nice if we could identify more precisely when it stopped working. Currently we know it's at some point between Linux 4.0 and 4.3.3. Can you try with Linux 4.2 ? And possibly also with Linux 4.4 ?

You can grab various (older) versions from

The .deb for Linux 4.2.6:

The .deb for Linux 4.4:

Otherwise if you know how to compile a kernel from sources, a git bisect to identify when it stopped working would be really useful.

Just want to double check, do you have the "firmware-misc-nonfree" package installed at version 20160110-1?

(You can check with "dpkg -s firmware-misc-nonfree")

Please also attach the output of "dmesg" with the kernel that does not work after having tried to use the wifi card in monitor mode.

Upstream is aware of the problem and there's a patch available already:

Should be fixed with linux 4.3.3-7kali2 that I just uploaded to kali-dev.

until its pushed to the main repo, you can try to add the following line to your sources.list, and update the kernel. Don't forget to reboot once done.

deb kali-dev-only main non-free contrib

Note: please make sure to remove this repository once you're done testing. Keeping it in your sources.list is a recipe to break things down the road.
