i'm using knoppix 5.1 liveCD and the ndiswrapper version 1.9 already installed on it
i've been trying to install my wireless pci card driver...

i followed the instructions, used the chipset information in lspci and lspci -n then went to the
ndiswrapper list and downloaded the right driver.
now when i do
> ndiswrapper -l
mrv8335x : driver install
device (11AB:1FAA) present

so i guess the driver has been installed successfully,
when i do

>iwlist wlan0 scan

i get the wireless network information i need to connect to.

now when i use the >netcardconfig
command i get to setup, where i fill all the correct information, the ESSID, the WEP Encryption key,...etc.
then it as ks me if i want to obtain adress automatically (DHCP), I click yes
then it gives me the following error message:

Sending DHCP broadcast from device wlan0 Operation failed.
Failed
Hit return to exit.

i've been working on this for so long, and i'm getting really desperate, i really need to be connected to the net for my school work. i would really appreciate anyone trying to help me out
thank you very much in advance
