I purchased USB Wireless adapter which runs smoothly on Windows and Ubuntu, but in BackTrack it's showing me a Bad password issue. From my reading I guess it's driver issue which BackTrack Kernel don't have drivers for RTL8191SU (my) Adapter.
The Realtek site have drivers for kernels
2.6-2.9. Even thought BackTrack 5R3 comes with
3.2.6, I tried to compile drivers which failed for me with make errors.
Additionally I cant get monitor mode in aircrack suite.
