    HOWTO: Broadcom Wifi & Ubuntu 10.04 LTS

    This posting should help those of you with Broadcom Wifi Hardware that
    are Upgrading/Installing Ubuntu 10.04 LTS. 10.04 uses the B43 Driver.

    1. How do I know if I have Broadcom Hardware?

    Open a Terminal Window and use these commands to get more information
    on your hardware, wireless, Windows loaded drivers, and Linux drivers
    that are currently blacklisted. Copy & Paste to prevent errors!
    Code:
    lspci
    lsusb
    lshw -C network
    lsmod
    ndiswrapper -l
    cat /etc/modprobe.d/blacklist.conf
    iwconfig
    iwconfig will show what the wireless is detected as......wlan0, ath0, etc.
    If you are requesting help, post the output of each command........

    Your options that can be used to get the Wifi functional: (B43 is the preferred for 10.04)

    1. Ndiswrapper and a Windows Driver....bcmwl5.inf & sys
    The correct 32/64 Bit drivers must be used to match Ubuntu 32/64 Bit.

    2. B43 and some Firmware that was downloaded/extracted when you
    enabled the Driver.


    #1 - NDISWRAPPER
    To install the Windows Drivers that are located on your Desktop in a
    folder named broadcom (.sys & .inf files):
    Code:
    cd ~/Desktop/broadcom
    sudo ndiswrapper -i bcmwl5.inf
    sudo ndiswrapper -l
    sudo depmod -a
    sudo modprobe ndiswrapper
    sudo ndiswrapper -m
    lsmod
    ifconfig
    iwconfig
    To make sure it starts on boot:
    Code:
    echo ndiswrapper | sudo tee -a /etc/modules
    Then I'd reboot or try:
    Code:
    sudo /etc/init.d/networking restart
    SKIP to FINISH below.......


    REMOVE WINDOWS DRIVERS:
    If you want to REMOVE the Windows Drivers:...............
    If the output of ndiswrapper -l shows any drivers loaded,
    remove ALL of them. If memory serves me correctly the command is:
    Code:
    sudo ndiswrapper -e bcmwl5
    sudo ndiswrapper -e ssb
    This should clean up nidswrapper & drivers and:
    Code:
    ndiswrapper -l
    should return nothing as being loaded.

    Then remove ndiswrapper:
    Code:
    sudo modprobe -r ndiswrapper
    Remove from startup file by editing:
    Code:
    sudo nano /etc/modules
    to remove ndiswrapper.

    SKIP to FINISH below.......


    #2 Use DEFAULT B43 Driver in 10.04
    The Firmware is missing and you just need to have an Ethernet Connection
    and ENABLE the B43 Driver, or if you don't have an Ethernet Connection,
    you can just copy the Firmware to the proper folders.

    Download the Firmware files located at:
    http://www.omattos.com/node/6
    to a USB Flash Drive and copy them to your Desktop, and Extract.
    You should have two folders b43 & b43legacy. You will be copying
    these folders to /lib/firmware/b43 and /lib/firmware/b43legacy

    Here are the commands I used on my old Compaq V5201US, running the
    10.04 LiveCD to get it working: (Open a Terminal Window)
    Code:
    cd /
    cd /lib
    cd firmware
    pwd
    ls
    sudo cp -r /home/loginname/Desktop/b43* .
    cd b43
    ls
    cd ..
    cd b43legacy
    ls
    exit
    Now you just have to Enable the B43 Driver:
    SYSTEM -> ADMINISTRATION ->HARDWARE DRIVERS
    should have a B43 Driver listed a driver listed for your wireless,
    if so enable it. (If by chance you have already ENABLED it, go ahead
    and let it try to uninstall, then install it again by clicking again.
    It should find the drivers and load them, because the Firmware is where
    it needs to be.

    Check Network Manager (right click on the icon) to be sure the "Enable Wireless"
    box is checked (It should be ENABLED already by default.)

    Check to see if you have wireless now. If not, you might need to
    check the Loaded Modules, making sure there are no conflicts with other
    Wifi drivers that might have been loaded, or others that cause conflicts.
    Code:
    lsmod
    Post the output of lsmod.

    You can check for errors with:
    Code:
    dmesg | tail
    You may have to remove other modules depending on what lsmod shows:.... ..
    What you will REMOVE depends on what you post as output from your commands.

    If lsmod shows module bcm43xx and other conflicts installed you will
    need to blacklist them, since you are going to be using B43.
    You may have to remove the following depending on what lsmod
    shows:
    Code:
    modprobe -r b44
    modprobe -r ndiswrapper
    You can use sudo nano /etc/modprobe.d/blacklist.conf
    and add the necessary modules to blacklist.

    Once this is all straightened up..........
    I'd reboot or try:
    Code:
    sudo /etc/init.d/networking restart
    FINISH:
    Click on the Wifi Icon in the top right toolbar and select the Network.

    Manual Choice:
    If you know the routers essid and the correct <interface>,
    shown by using iwconfig ie wlan0, ath0, etc.... replace that
    as the <interface> below:
    Code:
    sudo ifconfig <interface> down
    sudo dhclient -r <interface>
    sudo iwconfig <interface> essid "youressidofrouter"
    sudo iwconfig <interface> mode Managed
    sudo ifconfig <interface> up
    sudo dhclient <interface>
    iwconfig
    example......for Airlink and Wlan0
    sudo iwconfig Wlan0 essid "Airlink"

    It shouldn't take more than about 15 minutes......

    Okay, I have reinstalled Ubuntu, done the necessary updates, and enabled b43 in Hardware Drivers, but still I have no wireless capability. Here is the output of lsmod:

    Re: HOWTO: Broadcom Wifi & Ubuntu 10.04 LTS

    I'd try just blacklisting b44 first.

    Then, if you have downloaded the firmware, and have it copied to the proper
    places, you should be able to do a:
    Code:
    sudo /etc/init.d/networking restart
    or reboot. You should have the Wifi functional.

    This lsmod listing is different than what you posted on your other posting,
    so I assume you did another fresh install.

    These steps worked fine on my Compaq V5201US to make the Wifi Functional.

    Re: HOWTO: Broadcom Wifi & Ubuntu 10.04 LTS

    I have a Broadcom wireless as well and installed the restricted driver (System>Administration>Hardware Drivers) without issue; just select it, activate it and the light goes on. Just curious if there is a reason that that method was not mentioned to install the drivers. It worked like a charm on my Dell Studio.

    Better yet, I personally recommend PC/OS (http://www.pc-os.org) instead of Ubuntu. We have a 2005 Dell Inspiron 6000 laptop, which has a Broadcom 4311 (or is it the 4318? -- I can't remember) wireless card in it, and PC/OS properly detected it right off the bat without all the hassle involved with trying to set it up in Ubuntu (believe me, I've tried -- it's a BEAR to get that thing working in Ubuntu!).

    What's more, PC/OS is based on Ubuntu, although by default, it uses Xfce for the desktop (which I personally prefer, anyway), although there is a GNOME version available for those of you that are hooked on GNOME.

    Indeed, from what I've seen, you just need to hard-wire to your router (since obviously your wireless isn't working yet), open a terminal window (Applications/Accessories/Terminal), type sudo apt-get update and press enter. Wait for that to complete then go to System/Administration/Hardware Drivers and enable the driver listed.

    Also to be noted:

    - if you need to install ndiswrapper in order to use your wireless, the 2 packages you must install are on the LiveCD you installed with:

    /pool/main/n/ndiswrapper -> click on ndiswrapper-common first and let it install, then click on the utilities and let them install

    - if you need or want to use ndiswrapper, there is another program on the LiveCD that takes away all of the command line things: ndisgtk.

    /pool/main/n/ndiswrapper/ndisgtk -> click on the package there to install it. Once you have your Windows drivers, and ndiswrapper and ndisgtk both installed, forget the command line info and just do the following:

    - go to System/Administration and click on Windows Wireless Drivers. This will start ndisgtk (it is a GUI'd application). Check for any existing definitions and delete them if they are present, then just click on add and point it to your Windows driver files.

    Additionally, sometimes you see people make reference to the firmware cutter. If for some reason you need it and don't have an internet connection, it is also on the LiveCD at:

    /pool/main/b

    I did this the same way(hard wired to my router) and it worked just great for me as well, and I just started using Linux yesterday. I did this with my Dell 1545.

    Re: HOWTO: Broadcom Wifi & Ubuntu 10.04 LTS

    I have no B43 driver even listed in Hardware Drivers for my Broadcom BCM4312. The only driver listed there is "Broadcom STA wireless driver" and in the description box, it says "These package contains Broadcom 802.11 Linux STA wireless driverfor use with Broadcom's BCM4311-, BCM4312-, BCM4321-, andBCM4322-based hardware." I have this driver activated, yet I cannot use wireless because when I left-click on the Network Manager icon in the panel, it shows that wireless is disabled. When I right-click, I can't enable wireless because the "Enable Wireless" option is grayed-out.

    The results of the following command are:


    sudo lshw -C network

    Just to clarify, my computer does not have a physical wireless switch that toggles enabling/disabling wireless.

    Re: HOWTO: Broadcom Wifi & Ubuntu 10.04 LTS

    I finally got the B43 driver to display in Restricted Drivers after working with software sources and apt-get, and I have enabled it (and of course, disabled the other driver: the Broadcom STA driver). After downloading and installing the driver and after rebooting, I still have the same problem of not being able to use my wireless.

    The output of sudo lshw -C network now is:

    I don't think I see any module conflicts or anything, but I might be wrong. What should I do?

    Re: HOWTO: Broadcom Wifi & Ubuntu 10.04 LTS

    bcasanov,
    What is the output for:
    Code:
    ndiswrapper -l
    cat /etc/modprobe.d/blacklist.conf
    iwconfig
    What files are located at:
    Code:
    cd /
    cd /lib
    cd firmware
    pwd
    cd b43
    ls -alt
    cd ..
    cd b43legacy
    ls -alt
    If the firmware files are there it should work, if not they need
    to be copied as per the previous instructions. If the firmware files
    exist, then go to Hardware Drivers and disable B43, then re-enable b43.

    Then restart the networking or re-boot.
