HOWTO : RTL8191SE wireless card on Back|Track 4 R2

Lenovo ThinkPad X100e (Type 3508-65B) is equipped with AMD Athlon Neo MV-40 CPU and Realtek RTL8191SEvB wireless LAN Controller. It is working perfectly on Ubuntu 10.04 and 10.10. However, the wirelss card does not work on Back|Track 4 R2 (which is believed to be Ubuntu 8.04 with newer kernel). In additon, Back|Track 4 R2 is installed with Wicd as network manager.

This tutorial is going to show you how to install the r8191se_pci wireless driver on Back|Track 4 R2.

Step 1 :

Download the official Linux driver from Realtek. The current version is 0018 dated 2010-Oct-25 at the time of this writing.

Download Linux driver at RTL8191SE-VA2 section.

Step 2 :

Extract and compile the driver as well as copy the firmware the workable directory.

tar -xzvf rtl8192se_linux_2.6.0019.1207.2010.tar.gz

cd rtl8192se_linux_2.6.0019.1207.2010

make install

cp -Ra ~/rtl8192se_linux_2.6.0019.1207.2010/firmware/RTL8192SE/ /lib/firmware

Step 3 :

Load the driver.

depmod -a
modprobe r8192se_pci
ifconfig wlan0 up

or, reboot the system.

Step 4 :

Go to "Menu" -- "Internet" -- "Wicd Network Manager".

Select "Preference". Add "wlan0" to "Wireless interface".

Then click the "Refresh" button. Now, you should see the Access Points in the air. Select your desired Access Point, entered password and surf the internet.

Remarks :

RTL8191SE wireless card does not support aircrack-ng's injection mode. You may consider to buy USB wireless adapter, such as TP-Link TL-WN321G, TP-Link TL-WN821N and TL-WN822N. Or, changes the RTL8192SE to Intel 5100 as they all support monitor and injection modes.

That's all! See you.
