The NDISWrapper deb is no longer available due to complications. Installing from source is highly recommended. First download NDISWrapper from: http://sourceforge.net/project/showfiles.php?group_id=93482 Steps to Success 1) Unzip the package on your desktop. 2) Open a terminal. Type: cd /Desktop cd ndiswrapper-1.49 make sudo make install If you are on Ubuntu you have to install the build-essential package: sudo apt-get install build-essential If you are on Debian or Fedora you have to install the kernel headers: Debian: sudo apt-get install linux-headers-$(uname -r) build-essential Fedora: sudo yum install kernel-headers-$(uname -r) gcc After installing NDISWrapper you can install the driver like this: sudo ndiswrapper -i bcmwl5.inf You can see the status of an installed driver with: sudo ndiswrapper -l To remove an installed driver type: sudo ndiswrapper -r bcmwl5.inf You can download the bcmwl5.inf driver, which is for most Broadcom chipsets from your manufacturers website. All computer manufacturers make the device drivers available online. Once you find your driver it will be in .exe format. Install cabextract to extract the files: sudo apt-get install cabextract Place the drivers .exe file inside a folder on your desktop to catch all the extract files; we don’t want to make a mess of your pirty desktop. Name the folder something simple like “1″. Open a terminal and type: cd Desktop/1 Extract the files with: cabextract sp34523.exe Install the driver with: sudo ndiswrapper -i bcmwl5.inf Add ndiswrapper to the autostart modules list; add ndiswrapper to the bottom of the file: sudo gedit /etc/modules Then blacklist your bcm43xx driver to prevent conflict; add blacklist bcm43xx to the bottom of the file: sudo gedit /etc/modprobe.d/blacklist Then make sure the bcm43xx driver is not loaded: sudo rmmod bcm43xx Then load the ndiswrapper module: sudo modprobe ndiswrapper Your wireless card should be working now, and network manager you automatically accomodate wireless functionality.
