Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

This is a how to on how to get the stubborn infamous Broadcom 43xx wireless cards working:
First download the drivers from my website:
1) Blacklist bcm43xx driver
Open a Terminal window
Type "sudo gedit /etc/modprobe.d/blacklist"
At the bottom add the lines
# get rid of the default kernel drivers
2) Make sure network interfaces file is correct
Type "sudo gedit /etc/network/interfaces"
Remove all comments ('#') that you see so that all devices arehandled by the default network manager.
I would reboot here and make sure the wireless light goes out
3) Install ndiswrapper
Put in Ubuntu CD. Open Synaptic Package Manager (ClickSystem -> Administration -> Synaptic Package Manager),search for ndiswrapper-utils, and install it.You could also type "sudo apt-get install ndiswrapper-utils (IF you are not using ubuntu then make sure you have ndiswrapper-utils somhow installed)
4) Conigure ndiswrapper
Open terminal and navigate the folder where your drivers are."cd Desktop/bcm43xx"
Type "sudo ndiswrapper -i oem3.inf"Then type "sudo ndiswrapper -m"
Type "sudo gedit /etc/modprobe.d/ndiswrapper"Change the one line in that file to read "alias eth1 ndiswrapper"
Now you should reboot so all the drivers load.
Once you reboot the wireless light on your laptop should be lit. If it worked, you should be able to click the Network Manager icon in the top right. It will probably show a disconnected ennection becuase the computer is not plugged in.
Left click it and select eth1 from the drop down menu.
Click Wireless Connection, then Properties. Here just enter your network information. If you're using an unprotected network you should only have to type yout SSID.
Click OK and you should now be connected! If a green signal meter and connected network icon appear in the upper right you'll know it worked.

Well the problem with the 43xx cards is that thier firmware is not supported by certain distros (ubuntu for me) in which thats the problem... This how to shows how to use ndiswrapper with the drivers from windows and making it work. No matter if its blacklist or what...it works for me.

Sorry, but that isn't right. Distros may not include firmware, but I've never seen anything to suggest that certain firmware won't work on certain distros. If you have, please provide a link to the source.
You may need to create your own firmware with fwcutter and the Windows driver, but that is pretty easy. You just compile fwcutter, then run fwcutter WindowsDriverfilename.sys then run make installfw.
Honest, I'm not trying to belittle your contributions. I certainly encourage people posting what works for them and I hope you will continue to do so. It was not my intention to offend you and you have my apologies if I did so.
The problem with the bcm43xx driver is that the documentation and help are close to non-existant, so statements like "the firmware isn't supported by certain distros" can be very damaging. There is literally nothing out there to contradict these kinds of statements, so those who do have experience with this driver need to try and keep what little is out there as accurate as possible.
Just tried this after reinstalling Kubuntu (because of some grub problems) and it did not work. Should changes be made to /etc/network/interfaces to include eth1? I changed a couple of things, but with no luck. I think i'm going to be installing Gentoo though, because grub on my current install fails every month or so
Well these instructions tell you to do "ndiswrapper -m". This adds a line for "wlan0" into /etc/modprobe.d/ndiswrapper. Then the instructions tell you to edit that line which was added by the command "ndiswrapper -m", such that it referneces "eth1". On my machine, /etc/modprobe.d/ndiswrapper was a one line file, and it referenced wlan0, which was where I like to see the wireless device anyway, so i left it alone. I did not need to edit /etc/modprobe.d/ndiswrapper. My wireless device shows up as "wlan0", right where ndiswrapper put it.
Also a quick note. The drivers which are available at the compaq website for my computer did NOT work using this procedure. I had to download the ones in the instructions above.
Anyone get this to work for Slackware?
I'm running a fresh install of Slackware 11.0 on the same Wal-Mart special that klrtmto is.
I ran lsmod and modprobe to see if bcm43xx existed for me, which it doesn't, but I followed Step 1 here anyway.
Next, in step two, I don't have a /etc/network/interfaces ,
I do have a /etc/networks which is a file, and inside it there is only two lines that say
And where it says the light should go out, it's never been on since I removed the stock XP install and installed Linux.
I installed ndiswrapper with no problems that I can tell. I tried to build the 1.32 package from the sourceforge site but that failed, with some build error, so I downloaded a slackpack that was version 1.10 I believe. I then issued the commands listed in step 4, except there was no /etc/modprobe.d/ndiswrapper file, so I created one with the alias line. Of course, no success here. Any ideas? I've been working on getting this damn wireless garbage to work for I don't know how many days now.
Any suggestions or links would be very sincerely appreciated.
I'm aware of the bcm43xx.berlios.de site, but it's been down for some time now it seems
