I'm using Backtrack 5, R3 and an Alfa AWUS036NHR adaptor. It seems to work fine, and I can put it to monitor mode and I've succesfully used (e.g.) Reaver a few times. However, I can't seem to connect to (encrypted) wireless networks, at least using Wicd. I've enabled encryption in my network's properties, tried both PSK and Pass Phrase, and I'm sure it's the right password, but it always returns a 'Bad Password' error. I'm using the wext wpa supplicant driver (as recommended).
Many of the solutions in threads covering the same problem simply cause Wicd to stop interacting with my adaptor and not show networks at all anymore, so I'm running out of ideas. Any assistance would be appreciated!
