internet

depends on what card you have, and how much you are willing to read.
EDIT
if you open a console and type

Code:

sudo true ; ( set -x lspci lsmod ifconfig iwconfig ) >& result.txt

end it with ENTER key.
that code will show what you have in hardware and how it is configured...
the result will be saved as result.txt in /home/knoppix directory, move it to a USB-pen, floppy... and reboot computer to WINDOWS (leave it plugged in untill the computer ask you to remove the knoppix CD.
we can help you much better if you then post the text here, that text will show what you have in hardware and how it is configured...
a tip is to open the textfile in Internet Explorer, it may look weird in notepad or Word.
look at this link on some more how to save the file...
