KDE installation of wireless card BCM4318 [AirForce One 54g] 
hp pavilion of my brother has a BCM4318 integrated wireless card on motherbord, the open source driver works very badly so I tried using the windows driver
step 1 to identify the card: chris-laptop: / home/chris86
# lspci 06:02.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)
step 2 download driver windows the following link http://ndiswrapper.sourceforge.net/joomla/index.php?/component/option, com_openwiki / Itemid, 33/id, list_b / find the suitable driver to run the wifi card, using the location of firefox and trying to 06:02.0 (numerical string ID card)
the driver can be loaded directly at the following link:
ftp://ftp.hp.com/pub/softpaq/sp30001-30500/SP30379.exe
step 3 installation
unzip the driver.exe with winrar ( works fine with wine) and then as root I type ndiswrapper-i
bcmwl5.inf
# install ndiswrapper-l # check if everything went well
if you have the following response all is well: bcmwl5: driver
installed device (14E4: 4318) present (alternate driver: ssb) modprobe ndiswrapper then
step 4 configuration with YaST
apro yast dispositivi di rete > impostazioni di rete e seguo questo piccolo how to
In the Network Card Configuration Overview, click on "Add".
In the Manual Network Card Configuration, select "wireless" from the dropdown menu, leave everything else default and type in ndiswrapper in the module name box. Click on "Next".
On the Network Address Setup, goto the general tab, and set the Firewall to "External Zone". This may need some experimentation. Set Device Activation to Boot time (or Hot Plug). Click on "Next".
On the next screen configure the settings for your network. I've found it's best to leave the ESSID and encryption key fields empty and to let KDEWallet configure this, otherwise there may be conflicts. Most of the time, your Operating Mode will be set to "Managed". Again, you may need to experiment a bit.
In this context, I would like to share my experience of making the Broadcom Dell 1390 mini-pci wireless card work in a Comapq Presario V6000 laptop after I had installed OpenSuSE 10.2 (64 bit) in a dual boot configuration with Windows Vista Home (32 bit). Hopefully, this will save you some time and a lot of frustration, if you are on a similar track.
The laptop was connecting fine to the internet under Windows Vista through a Linksys wireless router with WPA-PSK security and it was set not to broadcast the network's ESSID. My objective was to achieve the same functionality under OpenSuSE 10.2. The first problem was to get the wirelss card recognized. I had to use ndiswrapper with bcmwl5.inf and bcmwl564.sys (available as the self-extracting R151517.EXE file from the Dell download centre) driver files for that. No other method worked. Then I tried to configured the card using YaST as described above. Although the blue light was now on, and the card could detect other visible secure networks when I used ' iwlist wlan0 scan ' it did not see my network (this was understandable as the ESSID was not broadcast). I could neither configure the security settings using YaST. The iwconfig command always reported the default settings only. It was such a frustration! Then I used the KDE KNetworkManager utility and the problem was solved. Could I configure the wireless card for my secure network and connect to the internet - It Was A doodle. The only thing Is that you need to fire up knetworkmanager Every time you boot up, I need to put it in your shell's profile file.
step 4 to load the module at boot
believe that this step is crucial because I did not initially make the change and the card did not work:
I went to edit the file / etc / sysconfig / kernel, replacing the MODULES_LOADED_ON_BOOT line = "" with MODULES_LOADED_ON_BOOT = "ndiswrapper"
then I rebooted and the sympathetic leed wireless card is on and the device worked properly
