    Unhappy MacBook Pro 8,1 (Broadcom BCM4331) + Ubuntu 12.04 - no wireless

    Hi,

    I read here that since linux kernel 3.2-rc3+, the BCM4331 wireless card that comes with my MBP 8,1 (late 2011) is supported by the kernel. I waited for Ubuntu 12.04 and installed the 64-bit version as soon as it was available. But no, the network applet still says "device not ready (firmware missing)" for wireless. I know that the instructions here work but it needs to be done for every new kernel version. I am attaching some information about my wireless card and the drivers that are loaded.

    Code:
    MBP:~$ lspci -nn
    03:00.0 Network controller [0280]: Broadcom Corporation BCM4331 802.11a/b/g/n [14e4:4331] (rev 02)
    Code:
    MBP:~$ lsmod | grep bcm
    bcma5974 17399 0
    bcma     26696 1 b43
    Code:
    MBP:~$ lsmod | grep b43
    b43      365785 0
    mac80211 506816 1 b43
    cfg80211 205544 2 b43,mac80211
    ssb       52752 1 b43
    bcma      26696 1 b43
    When I plug in my LAN cable, in Connection Information, the driver shows up as tg3.

    Code:
    MBP:~$ lsmod | grep tg3
    tg3 152032 0
    A couple of other things:

    Code:
    MBP:~$ dmesg | grep -i broadcom
    b43-phy0: Broadcom 4331 WLAN found (core revision 29)
    .....
    .....
    Broadcom 43xx driver loaded [ Features: PNL ]
    .....
    .....
    Code:
    MBP:~$ sudo lshw
    .....
    *-network DISABLED
     description: Wireless interface
     .....
     configuration: broadcast=yes driver=b43 driverversion=3.2.0-23-generic firmware=N/A link=no multicast=yes wireless=IEEE 802.11bg
    I installed firmware-b43-installer and rebooted, but no use. Maybe I missed a step, like rmmod some module and modprobe something else.
    Update: I just checked the output while installing firmware-b43-installer, turns out "Unsupported device found: PCIe [14e4:4331]", so that is a dead end as well.

    Can someone please tell me how to get this working?

    Thanks for your help!

    Re: MacBook Pro 8,1 + Ubuntu 12.04 - no wireless

    i just got this working on my MBP8,1 by following the wireless section on this page -
    https://help.ubuntu.com/community/MacBookPro8-2/Oneiric. No need to for the backports and what follows below it. Simply add the repo, update, install and reboot. Good luck!

    Re: MacBook Pro 8,1 + Ubuntu 12.04 - no wireless

    Thanks logisic, I did not know that the mactel repo had its own version of the firmware-b43-installer.

    However, I did something else and got it working.

    On Ubuntu 12.04, the b43 driver with the newer linux kernel 3.2+ supports the BCM4331 wireless card but the firmware is missing. "device not ready (firmware missing)"

    See this for elaborate instructions on getting WLAN to work. However, the only things needed to get it working are the b43-fwcutter (available in Ubuntu repos) and the Broadcom proprietary driver tar file mentioned there.

    Install b43-fwcutter and download that tar file. Then:

    Code:
    tar xf broadcom-wl-5.100.138.tar.bz2
    sudo b43-fwcutter -w "/lib/firmware" broadcom-wl-5.100.138/linux/wl_apsta.o
    This will install the missing BCM4331 firmware for the b43 driver to /lib/firmware/b43, from where it will be picked up automatically on reboot. Check the lshw output to confirm whether the firmware has been picked up.

    Suspend-resume and Hibernate might still cause issues, so as mentioned on the Ubuntu Buzz site:

    Code:
    # cp /etc/pm/config.d/default /etc/pm/config.d/default.old
    # echo 'SUSPEND_MODULES="b43 bcma"' >> /etc/pm/config.d/default
    If the default file does not exist, you can create it and just put in one line:

    Code:
    SUSPEND_MODULES="b43 bcma"
    Restart/suspend-resume as you wish!

    Confirming logisic's remarks, a fresh install of 12.04 on a Macbook 8,1, and then following the instructions at https://help.ubuntu.com/community/MacBookPro8-2/Oneiric works. The only remark is that the step of installing "linux-backports-modules-cw-3.2-oneiric-generic" should be updated to installing "linux-backports-modules-cw-3.3-precise-generic". Otherwise, this works perfectly.

    Re: MacBook Pro 8,1 + Ubuntu 12.04 - no wireless

    You don't even need the backports module anymore. It was backported from 3.2 kernel and Precise is already on 3.2 kernel.

    If you're on kernel 3.2.0-27 (current version if you kept your Ubuntu updated) then you don't need the suspend fix either since kernel 3.2.0-27 had a fix for that issue.

    Re: MacBook Pro 8,1 + Ubuntu 12.04 - no wireless

    Confirmed Kauboy's solution worked for me, however I have to run "modprobe -r b43 && modprobe b43" to get the wifi working completely.

    Thanks for everyone's help!
