Using Broadcom Wireless in Ubuntu Breezy 5.10
PPC: Breezy does not support the Apple Airport Extreme without building a custom kernel (see section on [link here]), but Dapper includes a native driver UbuntuHelp:WifiDocs/Driver/bcm43xx/Dapper.
Ndiswrapper
This section's contents are copied from a posting on Ubuntu forums.
Broadcom wireless cards are tricky to set up in ubuntu, and the forums are full of frustrated users seeking advice. Broadcom provide no Linux support (feel free to complain to your hardware vendor or choose a different card if you haven't yet shelled out your cash), but they can be made to work - and you're in the right place if you want to know how.
First, you need to find out if this guide is applies to you. Broadcom wireless cards come under many brand names and, in particular, are used in many Dell and Acer laptops. Look for the drivers supplied with your card (Dell usually store a copy in `C:\DRIVERS\NETWORK\ADDON`); if you have a file called `bcmwl5.inf` or `bcmwl5a.inf` then keep on reading. You won't succeed without following these instructions!
Removing previous ndiswrapper
- Before you start, clear out any mess from existing failed attempts to use ndiswrapper. Note that you shouldn't use a root terminal to execute the code in this how-to; use a normal terminal session instead.
sudo modprobe -r bcmwl5 sudo modprobe -r ndiswrapper sudo apt-get remove ndiswrapper-utils sudo rm -r /etc/ndiswrapper/ sudo rm -r /etc/modprobe.d/ndiswrapper
Some of these steps may report errors; just ignore them.
Installing ndiswapper
- Copy the `bcmwl5.inf` and `bcmwl5.sys` files to your desktop.
- Follow the advice given at How to add extra repositories.
- Open a terminal session and enter this code. Note that you need an active network connection for this to work; I've assumed that if you have access to a wireless LAN, you also have access to a wired network as a fallback.
sudo apt-get install ndiswrapper-utils sudo ndiswrapper -i ~/Desktop/bcmwl5.inf sudo ndiswrapper -m for conffile in /etc/ndiswrapper/bcmwl5/*.conf; do sudo sed --in-place 's/RadioState|1/RadioState|0/g' $conffile done
- Reboot your PC. On restarting, the light on your wireless card should come on. If not, try entering
sudo modprobe ndiswrapper
- Your card is now working. Open the networking configuration tool System --> Administration --> Networking.
- Select your wireless network card (probably `wlan0`) and hit the properties button.
- Tick the This device is configured box, and enter your network name and connection settings. Ask your office network administrator for support if you don't know what this question means, or copy your settings from Windows.
- BE CAREFUL entering your WEP key, if you're using one. You're expected to enter this in hexadecimal form; if you don't speak hex, prefix your key with s:
- Click OK. The screen should close fairly quickly; if it hangs, you probably aren't connected properly.
- Back in the Network Settings screen, select your wireless device as the default gateway device.
- Click OK. Again, the screen should close fairly quickly.
- Enjoy wireless nirvana. If everything works, you can delete the `bcmwl` file from your desktop.
- You might notice that the signal strength applet doesn't work properly. This is a known bug with these cards.
If you have trouble, try booting into Windows - if you dual boot - and checking that the card is enabled. Some laptops allow the wireless card to be switched off, usually with a special key combination, and I've not found a reliable way to make this work in Linux.
You can check if your card is disabled by using the command "sudo lshw -C network". If you see: *-network:0 DISABLED you have have disabled your card using a keyboard combination by mistake!
Native Drivers (using a Custom Kernel)
This document gives Ubuntu-specific (but quite general) instructions to install a driver for wireless devices with the Broadcom bcm43xx chipset, in particular Airport extreme cards.
You can find more detailed instructions at [1]. The open-source driver development page is located on the BCM43XX Developer website.
<!> This has only been tested with Ubuntu 5.10 (Breezy Badger) release using a self-compiled kernel as the bcm43xx driver requires a 2.6.15 or newer kernel.
The following instructions are not step-by-step. As installing this driver is currently only for advanced users, you are supposed to do your job, and it is not just cutting and pasting.
Install a custom kernel
First of all, you need a recent kernel, that is 2.6.15 or newer. Since Ubuntu 5.10 (Breezy Badger) comes with a 2.6.12 kernel, you need to compile one for yourself. If you are too lazy, you can grab a deb of JoeOblivian's latest here. Once you have installed it, refresh yaboot, reboot and check if everything is working fine.
sudo -s dpkg -i your-kernel ybin reboot
{i} Please note that some people prefer to use an Ubuntu 6.06 (Dapper Drake) kernel. If you prefer, feel free to use the latest kernel from Ubuntu 6.06 instead of building one for yourself.
Grab the Software
Then you need to download the IEEE 802.11 SoftMAC snapshot plus the latest snapshots of the bcm43xx driver (not the dscape one) and bcm43xx-fwcutter from the BCM43XX Developer Site. The following URLs are a known working combination.
- http://softmac.sipsolutions.net/softmac-snapshot.tar.bz2
- ftp://ftp.berlios.de/pub/bcm43xx/snapshots/bcm43xx/bcm43xx-20060119.tar.bz2
- ftp://ftp.berlios.de/pub/bcm43xx/snapshots/fwcutter/bcm43xx-fwcutter-20060119.tar.bz2
You will also need the latest versions of some wireless utilities.
apt-get install wireless-tools apt-get install wpasupplicant
Install the Firmware
Download and compile the fwcutter utility. {i} This tool will extract the binary firmware from the Apple Airport drivers and install it into the Linux firmware directory.
tar xjvf bcm43xx-fwcutter-20060119.tar.bz2 cd bcm43xx-fwcutter-20060119 make
Grab the firmware for your Airport Extreme from OS X. The following instructions assume you have a dualboot and you have mounted your OS X drive under Linux with root directory OSXROOT (most usually it's /macosx). If you have not done that then use some other means to copy that file ( {i} you can take a look at the README included in the fwcutter directory where some URI are given). Copy the Apple Airport driver to the build directory you just created and extract the firmware.
cp $OSXROOT/System/Library/Extensions/AppleAirPort2.kext/Contents/MacOS/AppleAirPort2 . ./fwcutter AppleAirPort2 fwcutter can cut the firmware out of AppleAirPort2 filename : AppleAirPort2 version : 3.90.34.0.p11 (400.17) MD5 : dc3a69aac95c68fe8edc760e39bbb2c9 WARNING!

Then install the firmware
export FIRMWARE_INSTALL_DIR=/lib/hotplug/firmware make installfw
Beware that the firmware shipped with OS X Tiger is not supported by fwcutter. In that case, you'll need to find a suitable firmware from one of the sources listed in the readme file. I'd post the firmware here if there were no legal issues. Update 20060121: the latest version of fwcutter successfully extracted the firmware from the OS X Tiger Airport Extreme drivers.
Install SoftMAC and bcm43xx
Download and install the latest softmac layer. This should install the softmac ieee80211 kernel drivers.
tar xvjf softmac-snapshot.tar.bz2 cd softmac-snapshot make make install
Then do the same for the bcm43xx snapshot. This particular snapshot works but check the website for more recent snapshots.
tar xjvf bcm43xx-20060119.tar.bz2 cd bcm43xx-20060119 make make install
Once you have done this, you are ready! Just type:
modprobe bcm43xx
and you should see in dmesg something like:
[ 57.137024] ieee80211_crypt: registered algorithm 'WEP' [ 57.194199] bcm43xx: set security called [ 57.194215] bcm43xx: .active_key = 0 [ 57.194219] bcm43xx: .level = 1 [ 57.194222] bcm43xx: .enabled = 1 [ 57.194226] bcm43xx: .encrypt = 1 [ 57.216599] bcm43xx: PHY connected [ 57.750700] bcm43xx: InitVals fileformat error.

Configure the network
Configure the IP address settings on eth1 using whatever method you prefer. DHCP works and can be most simply configured with System->Administration->Networking. If you use WEP can also configure your WEP key within that GUI dialog.
If you want to use WPA for greater security you need to use wpa_supplicant and that needs to be configured from the command line. The most complete instructions are in the WPAHowto. Here's a very quick guide for configuring WPA.
Modify /etc/default/wpasupplicant so Ubuntu knows that eth1 requires WPA.
cat /etc/default/wpasupplicant ENABLED=1 OPTIONS="-i eth1 -D wext -c /etc/wpa_supplicant.conf -d"
Modify /etc/wpa_supplicant.conf to contain your preshared key (PSK) and your SSID. The PSK must match what has been set on your access point.
cat /etc/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1
network={
ssid="YourSSID"
scan_ssid=1
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
psk="YourPSK"
}
Confirm that your access point is configured for WPA and then check the status of your WPA authentication under Linux using the wpa_cli tool.
wpa_cli > status verbose bssid=00:00:00:00:00:00 ssid=YourSSID pairwise_cipher=CCMP group_cipher=TKIP key_mgmt=WPA2-PSK wpa_state=COMPLETED > quit
For more details about making WPA-PSK work with the softmac version of bcm43xx take a look at the BCM43XX developer mailing list and in particular to this thread.
