Edimax WLAN-Stick N150 Nano EW-7811UN monitor-mode not working

Hello,
I know that there are a lot of problems with with wifi-sticks which don't support monitor mode, but I am able to put the same adapter into monitor mode on my laptop with kali-linux 1.1.0a and 2.0. My problem now is that on my raspberry pi 2 with kali-linux 2.0 installed I can't get the adapter into monitor mode.

Here are some of the command outputs on my laptop:

dmesg

Code:

[ 1339.932739] rtl8192cu: Chip version 0x10 [ 1339.964462] rtl8192cu: MAC address: 80:1f:02:e4:ca:af [ 1339.964467] rtl8192cu: Board Type 0 [ 1339.964539] rtl_usb: rx_max_size 15360, rx_urb_num 8, in_ep 1 [ 1339.964567] rtl8192cu: Loading firmware rtlwifi/rtl8192cufw_TMSC.bin [ 1339.964709] ieee80211 phy4: Selected rate control algorithm 'rtl_rc' [ 1339.965111] usb 2-7: firmware: direct-loading firmware rtlwifi/rtl8192cufw_TMSC.bin [ 1340.021552] rtl8192cu 2-7:1.0 wlan2: renamed from wlan1 [ 1340.035212] rtl8192cu: MAC auto ON okay!

Now the output on my pi:

dmesg

Code:

Code:

As you can see airmon-ng can't find the phy interface for the adapter. The driver seams to be the same but for some reason the the chipset text is slightly different, but i guess thats not a problem. The lsusb output is the same. The dmesg output of my laptop mentions, that a special firmware is loaded etc. All this stuff is missing in the dmesg output of my pi. It seams, that my laptop referes to the adapter as the rtl8192cu adapter that it is, but my pi refers to it just as a general usb device.

I think there is a problem with the drivers (it's every time a driver problem -_-). Of course I searched the internet for this "rtlwifi/rtl8192cufw_TMSC.bin" and drivers that would help me but I couldn't find anything..

did you solve the problem?
getting the same issue with mi RPI2.
the strange thing is that i can configure it to my network and surf through it.
bu i can not monitor it.
i also tried it using TP-LINK wn821n dongle....
same issue....

the only difference is that in the driver column i get ????????? and not rtl8192cu like you do.......
can anyone help me with this issue?

Hi everyone,
first of all - I GOT IT TO WORK :) :) :)

after seeing that this thread got
Replies: 1 (mine)
Views: 1,603

i thought that i wasnt the only one with this problem and after searching all over the web i am writing how i got it to work... hope it will help ;)

first of all u need a VM of kali linux (VMPlayer or Oracle VM VirtualBox <which i used> will do the trick)
p.s change the password from toor and regenerate the ssh keys - search online how to do it it is writen where ever there is a kali distro for download..

once you got kali running on a vm run the following commands:
mkdir arm-stuff
cd arm-stuff
apt-get install git
git clone https://github.com/offensive-securit...-build-scripts
cd kali-arm-build-scripts
./build-deps.sh

notice that when i ran this script it did not install everything i guess i has to do with dependancies or what ever.... so i wrote at the terminal one line at a time with 'apt-get install' until it installed all the build-deps
the current list is :
git-core gnupg flex bison gperf libesd0-dev build-essential
zip curl libncurses5-dev zlib1g-dev libncurses5-dev gcc-multilib g++-multilib
parted kpartx debootstrap pixz qemu-user-static abootimg cgpt vboot-kernel-utils
vboot-utils u-boot-tools bc lzma lzop automake autoconf m4 dosfstools pixz rsync
schedtool git dosfstools e2fsprogs device-tree-compiler libssl-dev btrfs-tools

and libncurses5 (i am making this guide only to 32 bit systems)

now for the fun part:
i dont know why but the rpi2.sh script is missing a few lines that without me adding them the script did not build the image right

so type

nano rpi2.sh

to edit the rpi2.sh file and at the section where it is writen
# Kernel section. If you want to use a custom kernel, or configuration, replace
# them in this section.
do the following modifications:
1. before the line "cd ${basedir}/root/usr/src/kernel" write the line:
read -p "it is time to modify the files . . ." -n 1 -s

2. before the line "export ARCH=arm" write the line:
export KERNEL=kernel7

3. instead of this lines:
make -j $(grep -c processor /proc/cpuinfo)
make modules_install INSTALL_MOD_PATH=${basedir}/root

write:

make -j $(grep -c processor /proc/cpuinfo) bcm2709_defconfig
make-j $(grep -c processor /proc/cpuinfo) zImage modules dtbs
make modules_install INSTALL_MOD_PATH=${basedir}/root

now we are ready to run the script:

./rpi2.sh <your kernel name and version - like MyKali_1.0>

at some point the script will stop saying:

it is time to modify the files . . .
<remember we added this line before>

now at a different terminal go to
edit /root/arm-stuff/kali-arm-build-scripts/rpi2-<your costum name>/root/usr/src/kernel/drivers/net/wireless/Kconfig
-#source "drivers/net/wireless/rtlwifi/Kconfig"
-source "drivers/net/wireless/rtl8192cu/Kconfig"
+source "drivers/net/wireless/rtlwifi/Kconfig"
+#source "drivers/net/wireless/rtl8192cu/Kconfig"

edit /root/arm-stuff/kali-arm-build-scripts/rpi2-<your costum name>/root/usr/src/kernel/drivers/net/wireless/Makefile
-#obj-$(CONFIG_RTLWIFI) += rtlwifi/
+obj-$(CONFIG_RTLWIFI) += rtlwifi/

after making this modifications return to the previous terminal and hit Enter so it will continue to run..

thats it you go the image :D

good luck
