sure, this is what I did:

1- Locate the windows driver. My laptop is a HP DV5020. The driver was 
located at c:/SWSETUP/WLAN/bcmwl5.inf

Your driver might be somewhere else. If you can't find it, download it 
from your laptop's manufacturer web site. Or check what is available at 
the ndiswrapper web site

http://ndiswrapper.sourceforge.net/joomla/

BTW, there are detailed instructions there as well, just in case these 
don't work.

2- copy it to your linux partition, for example

cp /media/hda1/SWSETUP/WLAN/bcmwl5.inf /home/dilip/drivers/bcmwl5.inf

3- install ndiswrapper-utils-1.9

sudo apt-get install ndiswrapper-utils-1.9
||
4- remove the bcm43xx module

modprobe -r bcm43xx

5- blacklist the bcm43xx module, so it does not load automatically on 
boot. Add the following line to your /etc/modprobe.d/blacklist file

blacklist bcm43xx

if you add it as the last line, make sure you add an empty line after 
that line

6- install the driver:
ndiswrapper -i /home/dilip/drivers/bcmwl5.inf

7- verify that it installed ok:
ndiswrapper -l

should get a message like this:
|
bcmwl5: driver installed|
| device (14E4:4320) present|

8- load ndiswrapper

modprobe ndiswrapper

9- test it using iwconfig

iwconfig

should receive a message like this:

lo no wireless extensions.

eth1 no wireless extensions.

eth0 IEEE 802.11g...... (it can get installed as wlan0 as well, i am not 
clear when one or the other result)

10- configure your wireless interface using iwconfig (text mode, in a 
terminal or at the console), or the System>Administration>Network 
applet, or the network-manager applet.

11- test your connection

12 - if everything works, add the line "ndiswrapper" (without the 
apostrophes) to the /etc/modules file, so it loads at boot

That should do it. If everything fails, consult
