This is a brief tutorial on how to get wireless LAN cards working on Linux. Although the instructions were written for Suse 9.3, they should work on all distributions.

Here is a brief rundown on what we need to do:

Download 'ndiswrapper' and prepare to compile it.
Compile it and install it to the system.
Add the drivers and create the driver configuration.
Start it up.
Setup IP adresses and networks.
Making it work all the time.

Getting ndiswrapper

NOTE: If your Linux distribution comes with ndiswrapper I recommend that you use the version installed by your system instead.

To get ndiswrapper, click here to download. Make sure that the version you download is compatible with your kernel. If you not sure of your kernel version then run this command.

Code:

uname -r

That should tell you your kernel version. You also need to have the kernel source installed on your computer, which may or may not come with your distribution. If it is not included, you can find the source to any kernel version here.

Installing it

Now that we've downloaded the file, we need to unpack it. First use the 'cd' command to change directory to wherever you downloaded it. For me it's /downloads

Code:

cd /downloads

Then unpack the package. Remember the package name is whatever you downloaded:

Code:

tar xvf ndiswrapper-1.3rc1.tar.gz

A new directory should have been created, so change to it.

Code:

cd ndiswrapper-1.3rc1

And now, compile and install:

Code:

make
make install

Adding the drivers.

Note:From this point forward, this guide assumes that the name of the driver is "bcmwl5". Substitute accordingly.
At this point you need to get the windows drivers you are going to install. You'll want to look for these files.

bcmwl5.inf
bcmwl5.sys

Place them in a folder, and run the following commands:

Code:

ndiswrapper -i /link/to/bcmwl5.inf

Obviously replacing the file location to wherever you have it.

A few additional notes:
If you try installing something with ndiswrapper and it goes wrong, it will still list it as installed even though it is not working. You need to run the command below to remove the driver from the list so you can try again.

Code:

ndiswrapper -e bcmwl5

If you are not sure what drivers you have installed then get a list by running this command.

Code:

ndiswrapper -l

Config + startup

This is the last bit we will do with ndiswrapper. We need to write to the ndiswrapper config file

Code:

ndiswrapper -m

Now we start it up.

Code:

modprobe ndiswrapper

Perfect! If anything goes wrong here it will be because of problems between the version of ndiswrapper and the kernel.

IP addresses and networks.

First of all we need to connect it to the network, now you can do this through the network devices of whatever distrobution you're using. I'm using SuSE so I'm doing it with YaST.

Now we need to check what your card is known to Linux as. Run the command below to find out if you have wlan or eth or whatever.

Code:

dmesg

Now keep that in mind. We need to setup the connection to the wireless station. Now if you use a program such as YaST to add the configuration here are the things you should know.

NOTE: If you setup your IP address with your card too then read below and do it all together.

Device type: Wireless
Configuration name: 0 (most likely 0, it will be what is shown when you run dmesg)
Hardware configuration name: wlan0 (most likely wlan0, it is what dmesg gives you, the whole of it)
Module name: ndiswrapper

If you dont have a graphical interface like that, you can connect using the following commands.

Code:

iwlist scan

This should list all networks it can find.

NOTE: If the network you are trying to connect to dose not broadcast its signal then you may not be able to connect to it. You probably can, just ask the administrator of the network to make it broadcast its signal if you can't connect.

Using IFconfig we will setup the network.

Code:

iwconfig wlan0 ESSID
iwconfig wlan0 key s:""

If you have a static IP address run this command.

Code:

ifconfig wlan0 address

Run the dhcpcd command to setup DHCP.

Code:

dhcpcd wlan0

At this point it should of started working, if your DHCP is done through the command line then run 'iwconfig --help' to see the commands you need to setup your DHCP. It will be different for everyone.

By now it should work.

Getting it to work every time.

We need to add this to the startup file so that it always loads when Linux does.

NOTE: Some distrobutions (if done through a graphical interface) will of already added this to the startup script.

Find the file /etc/rc.d/rc.local (sometimes just called rc) open it and search for 'dhcp', 'dhcpcd', 'wlan0', 'ndiswrapper' or any other reference to see if it has already been added, if not, add the following to the bottom.

Code:

echo "Set up wireless lan"
modprobe ndiswrapper
dhcpcd wlan0

Remembering to replace wlan0 with whatever yours is called.

And that should be it! Now I need to mention just one more thing. Sometimes Linux will try to start DHCP and fail because it has not loaded the ndiswrapper drivers. A good way to find out is if you have no internet connection, run 'dhcpcd wlan0' and it will tell you this.

Code:

**** dhcpcd: already running
**** dhcpcd: if not then delete /var/run//dhcpcd-wlan0.pid file

This means DHCP has failed, where you have added the code in rc.local, add 'rm /var/run/dhcpcd-wlan0.pid' above modprobe so that DHCP can restart. It should look like this.

Code:

echo "Set up wireless lan"
rm /var/run/dhcpcd-wlan0.pid
modprobe ndiswrapper
dhcpcd wlan0

And you're done! :D

	PROBLEM
	Written by Christopher Walken on 2006-10-23 12:17:40
	Hi! I have a HP Pavilion zd8179ea and have installed Linux Fedora on it. I am trying to make the wireless connection work. It has the Broadcom chipset. I followed the steps you provide at this address http://www.linuxforums.org/network/wlan_cards_and_linux.html but I have stuck somewhere. When I type the ¨make¨ command I get this error: [root@localhost ndiswrapper-1.27]# [root@localhost ndiswrapper-1.27]# make make -C driver make[1]: Entering directory `/home/user/Downloads/ndiswrapper-1.27/driver' Can't find kernel build files in /lib/modules/2.6.18-1.2200.fc5smp/build; give the path to kernel build directory with KBUILD=<path> argument to make make[1]: * [prereq_check] Error 1 make[1]: Leaving directory `/home/user/Downloads/ndiswrapper-1.27/driver' make: * [all] Error 2 [root@localhost ndiswrapper-1.27]# The same appears when I try to type the ¨make install¨ command. What is the problem? I can´t continue the installation further cause I get error messages from then and on. Please help me. Also is there a command of how I can type 2 or more commands at the same time? For example as you say the code is ¨make make install¨, how can I type ¨make¨ and ¨make install¨ at the same line? What is going wrong? Please help me as soon as possible cause my work depends on that... Provide me with details cause I am still a linux amateur Thank you

	I believe that you don't have the kernel source and headers, and whatnot, on your system. (You have the kernel, not the source and headers.) If you look near the top of the article you'll see he mentions this prerequisite and points you in the direction of the kernel source you'll need for this task.

	failure to create ndiswrapper module
	Written by urs on 2006-05-30 05:35:58
	this page is a very logical documentation for rather new users to linux. However, when I tried to run "modprobe ndiswrapper" I got the message below (message includes prior steps too). My debian dist is a testing version 2.6.15-1-486. I cannot find its kernel-source. Either the missing kernel-source or the fact the installed kernel is a testing version, causes this failure.... I'd appreciate if someone could get a look at it if he/she gets a chance... Thanks, Urs lazyboy:/home/urs/debian/WLan# ndiswrapper -i /home/urs/debian/WLan/W70n51.INF w70n51 is already installed.

You have to remove those first. Type "ndiswrapper -e w70n51" then type "ndiswrapper -e w70n51.sys" Navigate to the folder you stored your wifi downloaded windows drivers too and type "ndiswrapper -i w70n51.inf" then "ndiswrapper -m" (to make it activate on boot) and finally type "modprobe ndiswrapper". It should now work if all went well. Type "iwconfig" too see if it recognized it. If not, type "dmesg" and check for any ndiswrapper error messages.

	WIreless and Linux? Hobby only
	Written by BUICK1946 on 2006-06-02 15:16:53
	Only try wireless networking (or any technology under three years old for that matter) in Linux if it is your hobby. If you need it to work out of the box with a simple follow the instructions and click OK or NEXT you are stuck with Windows XP. many Linux distros are still having trouble coming to terms with PCMCIA in a laptop. Despite what the hardcore fans say wireless networking is still geek territory. Instructions, even those from the vendors are generally poorly written and ambiguous. Reminds me of windows 3.1 and MSDOS 5 instructions, designed to preserve the mystery and magesty of computing and prevent the unwashed massed from getting too familiar with their betters. In short if you need wireless within the next 2 or 3 years, you need WinXP.

	that's silly
	Written by justin on 2007-01-02 03:31:31
	Come on! My wireless worked in 2 steps in ubuntu: open wlassistant and click on the network! And, yes, it's not that easy for all cards and on all distros, but that's not Linux developer's shortfall, it's idiot vendors who don't give a shite enough about their users to pinch out a measly driver. Linux popular OS with some distros that are definitely for non-geeks who need wireless.

	I am not a linux guru by any means. But i am writing this on my laptop over my wireless connection. The laptop is running mandriva one. I used mandriva control center and ndiswrapper to load a windows driver for my pcmcia card. Using the configure lan Gui i was able to configure the connection and have it up and running in under 10 minutes. I never used the command prompt, i never read anything first, i accepted all the defaults (I changed one option, let users start connection to yes) and was up and running. it was easy. If someone could point me to some WEP documentation or help me with some questions i would appreciate it. You don't need WinXP.

	Wireless is not really the problem!
	Written by Ben on 2006-11-11 23:39:02
	Hi all, Well, I am not a Linux guru either, my wireless runs fine over an open network. It is using WPA_Supplicant that I have a problem with! :-( I just posted a query on the Fedora support forum on this site... Anybody has ideas about that? BTW, lame question (because a friend helped me set up the initial network): How do you probe to find out what driver your card is using? Kind regards, Ben
