I need help I'm new to Knoppix!

I have Knoppix STD 3.2 and everything works great with my Orinoco Classic Gold 8410 WD (firmware 8.01) except Airsnort. I receive the "Can't set Monitor Mode" error after the first 3 packet captures every time.

Is there another card that will work better or is my firmware version wrong?

Thanks for the help in advance!
