RPi 4 onboard wifi monitor mode and packet injections on kali-linux-2019.4-rpi3-nexmon-64.img

[BTears]

Hello forum,

I am a new guy trying to set kali linux on Pi 4 B 4gb and I didn't succeed to set onboard wifi to monitor mode and of course either tried frame injection.
I relied to that phrase on official page (https://www.kali.org/news/raspberry-pi-4-and-kali/) quote: "And now you can add to that list full Kali Linux support complete with on-board wifi monitor mode & frame injection support!"

Could you please tell me what I miss here and how I can make it work as it says?

I tried with images below:

RIG: Raspberry 4 B with 4GB ram
ADATA Premium Pro 64GB microSDXC U3

Connections: miniHDMI port 0 (close to power port) to HDMI monitor
ethernet cable on a switch

Procedure:

Format microsd card to FAT32
unzip berryboot-20191005-pi4.zip to microsd
boot pi and format mmcblk0 with ext4 filesystem.
reboot
Add OS via smb (kali-linux-2019.4-rpi3-nexmon-64.img)
reboot
Boot OS
Login to Kali with GUI user:root pass:toor

So a clean installation is ready on my Pi4 and here the problems begin:

Trying to set monitor mode on wlan0:


~# iw phy phy0 interface add mon0 type monitor
command failed: Operation not supported (-95)

So I make again a clean installation and try the below:


~# apt-get update && apt-get dist-upgrade -Vy && apt-get autoremove -y && apt-get autoclean && apt-get clean && reboot


after the update I tried again to set monitor mode


~# iw phy phy0 interface add mon0 type monitor
command failed: Operation not supported (-95)

FAILED



~# iw phy `iw dev wlan0 info | gawk '/wiphy/ {printf "phy" $2}'` interface add mon0 type monitor

Try 2020.1, and use airmon-ng to also put it in monitor mode instead of manually doing it.

[BTears]

Same with 2020.1 both 64bit and 32bit.



airmong-ng start wlan0

I can't reproduce the issue here at all.

It's possible you somehow have/got the wrong firmware, due to a misstep with enabling them in the metapackages. You could try running `apt install --reinstall kalipi-re4son-firmware` - this should place the correct wifi firmwares where they should be on the off chance that somehow the ones from the firmware-brcm80211 package replaced them when it was in the metapackage.

[krogstad]

You need to install pciutils package to get it to work, I believe. I loaded hwinfo, lshw, and pciutils after doing the `apt install --reinstall kalipi-re4son-firmware`.

After doing all that, I got it to work.
