Unable to get the realtek 8191su in Monitor Mode

[flyinghaggis]

Moved this from the Wireless Trouble Shooting Sticky to allow for a wider audience.

To the Mods - if this is wrong then please excuse my ignorance and take the appropriate action.

Hi,

I have just purchased a new unbranded USB to use on the vmware image I downloaded from the website, as the old belkin wasn't giving me the range I required.

The chipset is a realtek 8191 although when plugged into Vm it displays 8191Su.

I have the linux drivers for this item and have used the install.sh provided (for end users who are not familiar with Linux system) like me and seemed to install ok.

iwconfig lists it as being present but it will not start with airmon-ng start wlan1.

My Questions are as follows

1. Is this chipset supported - I have read that it is under the 8192 drivers?
2. If it is supported - Is there a driver that i can download with instructions pertinent to kali-linux ?
3. If the above is "don't waste your time" - Is the Atheros AR5008 or the TL-WN722N (AR9002U) compatable?

I have downloaded the backports-3.11.6-1 file but cannot get it to install so if there is a glimmer of hope
that this may work could someone help me with the correct syntax to get this installed I am having a
problem with the ./scripts/driver-select section.

I have today tried the instructions from a livecd 32 bit edition at https://forums.kali.org/archive/index.php/t-127.html but this too failed

Another quick update - after using the dmesg command I have discovered that the usb is using the r8712u: DriverVersion: v7_0.20100831 (don't know if this is relevant) and a msg at the bottom of the list stating ADDRCONF(NETDEV_UP): wlan0: link is not ready.

Somebody please please please help me - this is daein ma heid in!
Rab.

The realtek-firmware install the rtl8712u module (the driver is r8712u) which supports the USB devices based on the RTL8188SU, RTL8191SU and RTL8192SU.

One question: where did you get this driver you posted and that you installed from?.

It would be better if you post the model and brand of the USB device.

Please be more specific as to model and brand, even version of device is aplicable, also what have you done so far to install it.

Luck.

All I can tell you is it is an unbranded usb purchased from fleabay and that on the module itselft it says ieee802.11-11N 300n wireless usb adapter.
the driver came with the Usb-I realise that all the relevant drivers are included in the distribution but I thought (wrongly it appears) that this would
make a difference.

I have tried various things (too many to remember) that have been posted on the net and on both this site and the former backtrack forum.

As this is on a VM I will reinstall it to remove any conflicts that may have occured during my quest to resolve this issue.

Try putting interface wlan0 to monitor mode: airmon-ng start wlan0

See if it works.

Also try booting without the USB plugged in. After boot, plug it in and see if device is present: iwconfig

[flyinghaggis]

Thanks for responding, but as you can see from the above....I have already tried the iwconfig and it is there. Below is the output(which has been
tried on many occassions) or the airmon output-

root@kali:~# airmon-ng start wlan0

If airodump-ng, aireplay-ng or airtun-ng stops working after

Problem Solved - My thanks to all who viewed this thread.

[Badmodangy]

What was required for you to get this chipset into monitor mode. I have been working on this for it seems like Forever!! lol. I can't seem to get any of the modified drivers to install. I am fairly new to linux but not to computers in general. I know that I am overlooking the simplest detail. Did you have to install a modified driver to get the process completed? Any help would be greatly appreciated at this point.

when I type the following i get this below... just like you were reporting.. how did you solve it?

root@kail# airmon-ng start wlan0

===========================================

then nothing listed for interface chipset and dirver.. it doesn't creat a mon0 either when I type airmon-ng start wlan0

Please help.

[flyinghaggis]

Sorry to Mislead -

I just went out and bought another one (different of course) with the atheros chipset on board.

Quick update....have been told by another source to try - airmon-zc

airmon-zc start wlan0

I have a USB card with the same chipset and I can't get it into monitor mode as well.

I can confirm the same error messages as flyinghaggis.

probably off the main topic (the rtl8191su) but instead of seperate kill command, try
