ndiswrapper -i /cdrom/KNOPPIX/rt61.inf

If I try to load the device (ifconfig wlan0 up) I get an error that there is no such device present.
Has someone got the same problem?

Perhaps the output of: ndiswrapper -l , and iwconfig would help.

from:
http://ndiswrapper.sourceforge.net/m...index.php/List

Try this:
There will be 3 files net8185.inf net8185.sys net8185.cat. Open a terminal and change to user root with su and root password, then type ndiswrapper -i net8185.inf in the folder where you extracted the driver files hit enter. next ndiswrapper -l shows net8185 driver installed we now have to get the device id from root prompt type lspci -n at the bottom of the list is the belkin card card ID info 1799:701f write this down you will need it for the next portion of the installation. Now from root prompt type ndiswrapper -a 1799:701f net8185 hit enter this associates the net8185 driver with the device ID of the belkin card. from root ndiswrapper -l should now show
net8185 : driver installed
device (1799:701f) present
from root prompt type modprobe ndiswrapper . Then iwconfig. Notice the association of driver and device with ndiswrapper -a
option.
