Which ARM version ?

I used the rpi image for the Raspberry Pi - armv6l
No issue with amd64

Any progress on this? From https://forums.kali.org/showthread.php?23650-nl80211-not-found it sounds like somebody has just to add the modules to the kernel in that relase. Is this right? Currently I can't use my WiFi Sticks with airmon and I am not able to get the correct kernel sources and build scripts for kali to compile additional drives to the kernel by myself.

Which wifi card is this? I can't reproduce the issue here. Have you tested with the latest rpi image that we have?

The only time I can reproduce the issue is when a wifi card doesn't use cfg80211 (which nl80211 is part of now) or cfg80211 isn't loaded.

I'm having the same issue as peshay. I have a generic wifi dongle bought on adafruit (I'm pretty sure its this one: http://www.adafruit.com/products/814). The only info that I have about it is the output from lsusb:

root@kali:~# lsusb
Bus 001 Device 005: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter

EDIT: using the latest version of Kali (downloaded yesterday from http://images.offensive-security.com/ARM/kali-1.1.0-rpi.img.xz) on a RPi B+

Thanks for the update, as of that image, we are using a 3.12 kernel from rpi. The driver that MIGHT cover that device would be 8192cu, which is NOT mac80211 friendly.

I'm working on a 1.1.1 release which uses a 3.18 kernel. If you'd email me [email protected] I'll add send out an email if you'd like to beta test the 1.1.1 image and see if that helps at all.

Okay, digging around... unfortunately, for whatever reason, the rpi foundation decided to port in the rtl8192cu driver from the vendor instead of using the mainline drivers. I'm guessing to ensure more compatibility. Unfortunately, the vendor driver isn't mac80211 compliant, so on the rpi/rpi2, you will need a different wifi chipset to do anything more than connect to a wireless network, or use it in AP mode.

Due to vendor changes to the kernel, the rtl8192cu driver in the rpi kernel is not the same as in a mainline (what we use on amd64/x86) kernel, so unfortunately there isn't much to be done, unless someone wants to take the rpi kernel, unport the vendor changes, and bring the mainline rtlwifi stuff back in.
