I purchased USB Wireless adapter which runs smoothly on Windows and Ubuntu, but in BackTrack it showing me 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.

Any possible solutions or instructions?

Since your adapter works well on both windows and Ubuntu, it should also work on your BackTrack. Now that you get the bad password issue, the first thing you should do is to check your password and maybe you can try the generic driver. By the way, how about the encrypting program? If that break down, the adapter will always show you bad password errors.

try generic driver? Can you give me more info? what you mean by encrypting program? –  Jones Nov 28 '12 at 14:24
    
In the kernel driver list, there should be a "generic driver" item used for the device that is not in the device list. To connect to your wireless, your computer will encrypt your password and then send it to check. If the encryption break down, you will not succeed to connect. –  Fity Nov 28 '12 at 14:51
    
1) Mention the full/approximate path, I don't see any generic driver. I tried compat-wireless drivers to compile which failed to do for my chipset. 2) Crypting is performed by Wicd manager. Hence I don't have anything to do with it. –  Jones Nov 28 '12 at 15:44
