Installing Lenovo G400 Wifi Driver on Ubuntu Hardy

ubuntu hardy on lenovo g400
My friend has a Lenovo G400, at first he using Windows XP on it but the driver is not works, I opened the manual book and finally i know that this machine is bundled with Windows Vista.
But Vista is still expensive for my friend, then I suggested him to use Ubuntu Hardy on his notebook. Everything was run normally until I tried to connect to internet using this machine but the wifi led was not on.

I browse in google then found an article that wrote the solution. I tried in my friends computer. here the steps:
  • Create init scripts. Open the Terminal and run sudo gedit /etc/init.d/wirelessfix.sh. Copy the following lines.

 #!/bin/bashmodprobe -r b44
 modprobe -r b43
 modprobe -r ssb
 modprobe -r ndiswrapper
 modprobe ndiswrapper
 modprobe b44

  • On the Terminal make the init script executable using sudo chmod 755 /etc/init.d/wirelessfix.sh
  • Make the script run during boot up, sudo update-rc.d wirelessfix.sh defaults
  • Install needed packages and windows drivers.
    sudo apt-get install ndiswrapper-utils-1.9 ndiswrapper-common
    wget http://ftp.us.dell.com/network/R140747.EXE
  • Reboot your machine.
  • Unzip the downloaded R140747.EXE using unzip -a R140747.EXE
  • cd to the driver directory (/home/~~/Driver/)
  • Install the windows driver using sudo ndiswrapper -i bcmwl5.inf and sudo ndiswrapper -l. The last command should indicate detection of the adapter likebcmwl5 : driver installed
    device (14E4:4311) present (alternate driver: bcm43xx)
  • Finish everything with sudo ndiswrapper -m and sudo modprobe ndiswrapper
  • Reboot your machine. The wifi switch button beside the machine should now work and your the nearest wireless networks should now be detected.
  • To connect to the wireless network follow the Basic Procedure in Connecting to the Internet from help.ubuntu.com
