I am able to go into ad-hoc and managed mode just fine.

Why can't I enter monitor mode?! I am trying to get kismet working
I think I have at least 1.04 of my drivers, is there a way to check?

Any help would be great!
Thanks.
You need to upgrade your driver. If you dowemload the latest driver from sourceforge + firmware + ieee80211
Now the only nasty thing is that it seems the drivers on the knoppix CD are not installed at their regular place, hence the unload/remove script that goes together with the source does not work. Remove manually the ipw/ieee80211 files before installing the new ones, otherwise it sure will NOT work.. Don't forget to copy the firmware to the hotplug dir
After it it works fine.
If there is need for it I can see if I can make the compiled driver available for downloading
