Configuring the ndiswrapper module for wireless controllers without native Linux drivers in Fedora 8

Author(s)

Introduction

This guide is designed to help you configure a wireless controller under Fedora 8 which does not have any native drivers. Thanks to the ndiswrapper module, you are able to run drivers written for Microsoft Windows XP/2000 under Linux. This method should only be followed if there are no native drivers available for your wireless controller or the drivers available do not work properly with your card.

Important Notes

Windows driver version

For best results you should use drivers written for Microsoft Windows XP. Vista drivers are not recommended.

64bit Linux

When installing the Windows drivers with NDISwrapper you will need to install drivers which match the architecture of your Linux distribution. So you will install 32bit Windows drivers when using 32bit Linux and 64bit Windows drivers when using 64bit Linux. Unfortunately many manufactures have not release drivers for the 64bit version of Windows XP so your only recourse would be to reinstall a 32bit version of Linux.

4K Stack Kernels

Fedora as standard uses a kernel with the 4K Stack option enabled. This can be a problem with NDISwrapper as many Windows driver expect a greater stack size. Unfortunately the only way around this is to compile a custom kernel. This is beyond the scope of this guide.

If you are getting random system lockups while using NDISwrapper then the 4k stack issue may be the issue. Try finding a different set of Windows drivers and see how that work.

Notes

We will be using 'nano' as our text editor of choice but you can use whatever you wish.

While this guide is mainly focused to laptop users there isn't any difference for desktop users.

Prerequisites

You should run a full update for your installation of Fedora to ensure you have all the latest packages installed.

Installing the NDISwrapper module

The ndiswrapper module is not included with Fedora 8 so we will need to use a 3rd party repository. Here we will be using the ATrpms repository.

1. Load up a terminal window if you are in the graphic interface.

2. Switch to the root user by entering the command “su -” (without the quotes) and typing in your root password

3. Edit the file /etc/yum.conf. Using nano we type the command:

nano -w /etc/yum.conf

4. If you have already configured yum to use the ATrpms repository then append “*ndiswrapper*” to the end of the “includepkgs” line and skip the next 3 steps. Otherwise continue on.

5. Add the following to the bottom of this file:

[atrpms]
name=Fedora $releasever - $basearch - ATrpms
baseurl=http://dl.atrpms.net/f$releasever-$basearch/atrpms/stable
gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms
gpgcheck=1
enabled=1
exclude=*kmdl*i586*
includepkgs=*ndiswrapper*

6. Save the file. In nano you press Ctrl-X, answer yes to the “Save modified buffer” question and then press enter on the file name to write.

7. If you have not previously setup ATrpms execute the following command:

rpm --import http://ATrpms.net/RPM-GPG-KEY.atrpms

8. Now execute the following command:

yum install ndiswrapper

The ndiswrapper module is now installed.

Configuring NDISwrapper

First find out which wireless controller you have in your system. This website should provide you with details on which card you have in your laptop. Alternatively you can use our Linux Wireless Chipset Detector utility which will determine which controller you have.

Download the Windows XP driver which is appropriate for your wireless controller. This website should recommend a driver to use based on the laptop you are using. If not then the driver from your manufacturer should work fine. You can also find a list of drivers from the NDISwrapper site.

Extract the contents of your driver. If you have an .exe file you will need to use either cabextract or unshield to extract its contents. If you have a zip file just use unzip.

Now execute the following two commands as root:

ndiswrapper -i <location_of_your_driver>/<the_driver>.inf
ndiswrapper -l

Change the above from <location_of_your_driver> to your driver's directory and change <the_driver> to match the name of the .inf file in the driver's directory. For example a Broadcom controller is sometimes called bcmwl5.inf and is in the bcmwl folder. You would type in:

ndiswrapper -i bcmwl/bcmwl5.inf
ndiswrapper -l

The last line should print out a list of the installed drivers. You should also see “hardware present” printed next to your driver. If you do not see “hardware present” it is likely that you installed the wrong Windows XP driver.

Now type in:

modprobe ndiswrapper

And the wireless controller should be active. You can try to see if the controller is working by typing:

iwlist scan

This should print out a list of access points in your area.

Finally we need to tell Fedora to load this driver each time we start the computer. Type in the following:

echo "modprobe ndiswrapper" >> /etc/rc.modules
chmod 755 /etc/rc.modules

You should now have a working wireless controller.
