Windows Wireless Driver (ndiswrapper)

I have a friend who has a computer which can not connect to the wireless network but the wireless hardware is working well in windows ( his name is Martin )
Strange.......in windows it works but in Linux not. The hardware is ACER IPN2220 Card

How to solve this ? ( you may use online or offline solution )


Offline solution :

1. we have install a program called ndiswrapper manually
2. get 3 packages from http://packages.ubuntu.com and install them in order
3. ndiswrapper-common
4. ndiswrapper-utils
5. ndisgtk
6. In order to set up ndiswrapper, it is necessary to obtain the Windows driver for your wireless card. Generally, the best way to do this is from the CD supplied with your wireless card. You should copy two files to the same place on your computer, one ending in .SYS and one ending in .INF. If you find any files which end in .BIN, also copy those, let say copy them to home folder.

7. go to System → Administration → Windows Wireless Drivers
   
8. Click on install driver button and point to home folder, choose neti2220.inf and click ok to install it
9. Click on Configure button to do the wireless setting.
