How to set up the Broadcom BCM4318 wireless card that comes with Amilo 1655g laptop on SuSE Linux 10.1 and linx mint Daryna 4.0 (ubuntu gutsy based)

I recently bought a Fujitsu Siemens Amilo 1655g laptop with an AMD Turion(tm) 64 Mobile Technology ML-32 processor and 1GB of Ram.The laptop comes with a broadcom wireless card

( Broadcom BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller ) .


The card was said not to work with linux on various forums I 've read.
Here are the steps I took in order to make it work on SuSE 10.1 x86_64.

1. Install ndiswrapper from Yast.
Go Yast->Software Management , Search for ndiswrapper , tick , and press Accept to Install.

More Details here  http://www.tuxmagazine.com/node/1000167


2. Download the windows driver from here http://www.linuxant.com/driverloader/drivers.php

It's the "Airforce One" Broadcom devices with PCI ID 14E4:4318 ( ftp://ftp.support.acer-euro.com/notebook/ferrari_4​​​​​​​​​​​​​​​​​00​0/d​riv​er/​win​xp6​4bi​t/8​021​1g​.​zi​p ).


3. Extract the zip and run as root

ndiswrapper -i bcmwl5.inf

from where the .inf file is located.

next

ndiswrapper -l

you should see something like that:

Installed drivers:
bcmwl5 driver installed, hardware present

please read http://www.tuxmagazine.com/node/1000167

for more details.

4. On Yast -> Network Devices -> Network Card , I have selected

Traditional method with ifup.

But I suppose network manager will be ok too.


5. Add a wireless network interface if you dont already have.

Set the module name to ndiswrapper. This should load the ndiswrapper kernel module at boot.



6. Set the other details of your wireless card like Ip (static or via DHCP if you use it) , Gateway (routing).

These are on the Address tab.On general tab I have Device Activation On hotplug and User Controlled checked.
I dont think other setups would make any trouble .
The key points of this setup are :
  • first to load the ndiswrapper on kernel,
  • set up the address , ssid ,encryption of your wireless card,
  • and finally install a second kernel module that I ll refer later as ndiswrapper can't start/stop the hardware.


7. press next and Set the details of your wlan

press next and finish.


8. Now something Important.

Download the fsaa1655g source from http://www.marvec.org/amilo/

Everything is ok but the wireless card is not started!

This module can start/stop the card.

Extract the fsaa1655g source and run make && make install

Update 20071109

on linux mint celena (or ubuntu feisty)
I had to comment out this line (line 32) on fsaa1655g.c
before running make :

/*#include <linux/config.h>*/

there is no config.h nowadays, I think it's deprecated.


9. Reboot .


10. Check if ndiswrapper module is loaded.

To see if the ndiswrapper kernel module is loaded after boot� , issue as root :

lsmod

this command lists the loaded modules of the kernel and you should see somewhere ndiswrapper.

(it's a great possibility that if ndiswrapper module wont load after reboot you should issue ndiswrapper -m and reboot )


11. Now the point is to load fsaa1655g module into the kernel , and restart network

Issue as root

modprobe fsaa1655g

ifdown wlan0

ifup wlan0


This little script I wrote starts / stops wireless card and interface depending on whether it is started or stopped.

I found it useful as I dont like my wireless to start automatically.
I put it on /usr/local/bin.

Update - 20071109
Updated the script for my new installation linux mint celena on my laptop (it is based on ubuntu feisty).
I have the same ip on both interfaces (wireless and ethernet) set static and I noticed problems when having both
interfaces up.
I think I also noticed problems even when having different ips on the interfaces.
So i stop the ethernet interface before bringing up the wireless and vice versa.

I also had to put some sleep delays after stopping each interface in the script.

The whole installation at mint/celena is more or less the same.
Here are the steps I followed :
http://ubuntuforums.org/showthread.php?t=285809

I used wep-encryption on the router and on gnome network I set my wep ascii key .
I remember that using wpa encryption needed the wpa-supplicant script to run
so I went with wep.
I also removed various scripts in /etc/network that delayed the starting / stopping script
and decided I didn't need them
here is my /etc/network listing now:

bak directory stores the backups of the if-up.d e.t.c. directories.




Update 20071126

On Linux mint 4.0 that is based on ubuntu 7.10

I was able to use WPA-PSK encryption since it is supported.

On the network tool i chose wpa-psk encryption.

Don't forget to blacklist the bcm module that is loaded in kernel

Blacklist native bcm43xx drivers

Issue: sudo gedit /etc/modprobe.d/blacklist

Add the line: blacklist bcm43xx

After saving type at the terminal: sudo rmmod bcm43xx

You can add it to your kde or gnome menu , and set it to run as root.

Don't forget after you copy paste the above code to a text file , to make this text file executable:

Right click on the file and change it's permissions or in the console type: chmod +x <script's file name>



12. Now you should have wireless if everything went Ok.

Check with the ifconfig and iwconfig commands .

Disconnect your wired ethernet adapter and ping an ip on your local Lan.

Does it pong?

Good luck..

Update 20080628
On linux mint elyssaa which is based on ubuntu hardy.
Every time the installation of this card becomes different.
This time :
sudo apt-get install bc43-fwcutter
if it doesn't find it google a little bit to find the correct repository for this
 package.  bc43-fwcutter will install the correct driver during installation. Run above command from console.
Follow the steps (number 8) described above to install fsaa1655g .
Uninstall ndiswrapper if you had installed it .
the script is modified this way with just deletion of the loading of ndiswrapper in load_necessary_modules.
