Raspberry Pi - RTL8188CUS Wifi dongle Monitor mode issue

[snir_l]

Hi guys

I own a Wifi USB dongle: RTL8188CUS. I have a personal laptop which runs Kali Linux, and when i plug it to my Laptop i can get it into monitor mode with no issues.

Unfortunatly, the issue begins when i plug the same dongle to my Raspberry Pi 2 B. On my Pi, i run Kali Linux as well, and i'm trying to get the same dongle into monitor mode with airmon-ng, and with "iwconfig wlan0 mode monitor", but Both fails. Looks like to me that its not a hardware issue, since i can get it into monitor mode on my laptop, but not on the pi.

The Airmon-ng shows on the PHY "null" for some reason.

Just to mention, my Pi recognizes the dongle well, and i'm getting wifi signal and can clearly see the interface of the dongle on iwconfig. however the only issue is with the monitor mode.

few things i already try:

updated realtek firmware with apt-get install firmware-realtek
Also Tried airmon-ng check kill
Aircrack is updated to the last version


Any suggestions? Thank you guys

I am in the same situation as you.

I am on the Edimax RTL8188CUS and I can't seem to get monitor mode to work as well. Was wondering if you manage to get it up?

I have this one and it is working fine, even on the same Pi2 with ALfa RT3070 adapter.

What can I help - some script checks or firmware etc.

PS: Sorry just saw the issue is in monitor mode, didn't check that. I'm using it only in managed mode.

Hi All,

So after doing research for a few days I gave up and bought a TP-Link WLAN USB (WN722N) http://www.tp-link.com/en/products/d...TL-WN722N.html

Monitor mode works fine after that. I also did dual boot on a laptop with Kali together with Win 7 Pro and the Edimax WLAN USB dongle with RTL8188CUS chipset works fine on laptop.

The thing is that the ARM version of Kali for Rasp Pi 2 does not work for chipset RTL8188CUS however it works fine if you are booting it up Kali on a laptop.

I hope this helps everyone =) ... Also hopefully ARM Kali can help fix the chipset for RTL8188CUS.

As am I.

Has anyone been able to get the RTL* chipsets in monitor mode yet?
I've tried 3 different types wifi cards all with Realtek chipsets
Will post back if I do.

So I've revived some old threads, probably one too many.

Seems rebuilding the kernel with rtl8192cu instead of the mainline version that comes with the current kernel enabled will do the trick,

here is the article.

I don't have the time to do what the article suggests at the current moment.

Can anyone give it a go and post back?
