hola a todos tengo una placa de red wifi awus036h, utilizo el backtrack 5, 2.6.32-21-generic, y despues de googlear hasta el cansancio di con una posible solucion, para mi problema de que no me la reconocia.
Desde terminal seguimos los siguientes pasos.
1. sudo rmmod r8187 rtl8187 mac80211 cfg80211
2. sudo mkdir /usr/src/drivers
3. cd /usr/src/drivers
4. sudo wget http://dl.aircrack-ng.org/drivers/rtl8187_linux_26.1010.zip
5. sudo unzip rtl8187_linux_26.1010.zip
6. cd rtl8187_linux_26.1010.0622.2006/
7. sudo wget http://patches.aircrack-ng.org/rtl8187_2.6.27.patch
8. sudo wget http://patches.aircrack-ng.org/rtl8187_2.6.32.patch
9. sudo tar xzf drv.tar.gz
10. sudo tar xzf stack.tar.gz
11. sudo patch -Np1 -i rtl8187_2.6.27.patch
12. sudo patch -Np1 -i rtl8187_2.6.32.patch
13. sudo make
14. sudo make install
15. sudo modprobe r8187
