It's not a very good guide

You don't need ndiswrapper for your card to work !

Hello babbutycoon

Welcome to the forum.

I have a 4318 in my laptop and haven't used ndiswrapper since Fedora 8 was released.

I'd seriously suggest uninstalling ndiswrapper and using the new b43 driver that is built into Fedora.

If you want to give that a try, post back and we can talk about it.

EDIT: I can't get the guide you followed to load at the moment, but does it contain the information to either disable NetworkManager or to set the card "Not to activate at startup" in Network Configuration?

Hello babbutycoon

We need to be sure of one thing first. If your Fedora 8 installation is from the original CD/DVD and hasn't been updated you will need to download one file. If you have updated beyond a certain level then you will need a different file.

If you run the command:

Code:
rpm -q b43-fwcutter
and post back the result I'll know which set of notes to give you.

Hello babbutycoon

This is what you need to do then.

With that card then you should only need to download the firmware, cut it and configure the card with NetworkManager.

Download this file and put it into a directory somewhere:

http://downloads.openwrt.org/sources...0.53.0.tar.bz2

Acquire full root rights over your machine with this command in a terminal window:

Code:
su -
That's a space and a minus sign after the su. It gives you full root rights over your machine rather than just root rights over your ordinary users environment without it.

Use the cd command to navigate into the directory where you downloaded the above file. Issue the command:

Code:
tar xjf broadcom-wl-4.80.53.0.tar.bz2
That unpacks the file archive you downloaded and will create you a new directory where you are working called 'broadcom-wl-4.80.53.0'.

cd into that and then the 'kmod' directory within that and use the command:

Code:
b43-fwcutter -w /lib/firmware wl_apsta.o
That cuts the required firmware for your card from the downloaded file and places it in the correct place for the b43 driver to find it.

Check and see if you have NetworkManager showing on the top Gnome Panel to the right in the notification area. If you have ignore the next part.

Go to the "Gnome System Menu - Administration - Services", tick NetworkManager and NetworkMangerDispatcher, make sure they are started and the settings are saved so they start at next boot.

Restart the machine and left clicking on the NetworkManager icon should bring up a list of wireless access points to connect to.

If it doesn't work there are a couple of possible things we may need to alter, mine worked without them though so we'll not complicate things if we don't need to.

Hello babbutycoon

There is no option for "New" in NetworkManager. I think that if you look at the title bar of the configuration program you are using directly you open it you will see "Network Configuration" written there. That is NOT NetworkManager.

Look at the last part of the notes where it says to use NetworkManager in the top right of the Gnome panel and how to get it if it's not there.

When I installed my 4318 this way it never appeared in Network Configuration.

Hello babbutycoon

Are you sure you are using Gnome as your desktop manager? If you deleted the top panel for Gnome, where do you have the menu's to access your applications?

Hello babbutycoon

Run these commands and post back:

Code:
su -
to get full root control.

Code:
lsmod | grep b4
to ensure that the b43 module is loading.

Code:
iwconfig
to see if a card is being detected.

Code:
iwlist wlan0 scan
to see if it can be instructed. Obviously, if iwconfig finds a wireless interface other than wlan0 then substitute it in the iwlist command.

Check in the:

Code:
/lib/firmware
directory to see that there is a b43 subdirectory and look in that to see that there are cut files in there.

you'll probally need to blacklist the ndiswrapper driver and follow the Broadcom how to in my sig and you should be golden.
