Recently i bought a Realtek USB wireless card with RTL8187L chipset. Backtrack 5 R3 kde installed and 3.2.6 is kernel version.

I tried to use injection with this card it's work but after 15 second will stop and disconnect. I ask seller to know about this matter, he said should be install exactly RTL8187L driver (not rtl8187 & etc...)
Found a driver in Realtek website and try to install it :
Code:
apt-get install build-essential linux-headers-`uname -r`
cd Downloads/rtl8187L_linux_1041.0209.2012
make
make install
But error showing:
Code:
root@bt:~# apt-get install build-essential linux-headers-`uname -r`
