No space left on device when setup iwconfig

[duke_ly]

Hi,
I use Knoppix 3.6 and kernel 2.6
IBM Thinkpad R40

I got my wireless card IWP2100 recognized automatically.

iwconfig gives me the status of the card.
But every time I setup wireless env. for it using iwconfig, the change will not be saved.

I tried nniswrapper instead and it gave me the following error:

ndiswrapper -i /mnt/hda1/temp/xxx.inf

> cannot write /etc/ndiswrapper/... no space left on this device

Do I have to install knoppix in a drive in order to do this? I heard some guys successfully setup wireless without install knoppix.

Thanks a lot guys
Doug
