    [SOLVED] Broadcom BCM4311/Ubuntu 12.10/Dell Latitude D620

    Hi, I'm a Ubuntu newbie currently testing out Ubuntu 12.10 on a Live USB. From my network controller, there does not seem to be an option to connect to a wireless network. The wired connection via Ethernet cable worked fine.

    09:00.0 Ethernet controller [0200]: Broadcom Corporation NetXtreme BCM5752 Gigabit Ethernet PCI Express [14e4:1600] (rev 02)
    0c:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01)

    I've tried the following to get my wireless to work:

    • Turning on the bcmwl-kernel-source driver in "Additional Drivers": nothing happened.
    • Typing in
      sudo apt-get --reinstall install bcmwl-kernel-source
      • DKMS: install completed.
        ERROR: Module b43 does not exist in /proc/modules
        ERROR: Module b43legacy does not exist in /proc/modules
        ERROR: Module ssb is in use by ssb_hcd
        ERROR: Module bcm43xx does not exist in /proc/modules
        ERROR: Module brcm80211 does not exist in /proc/modules
        ERROR: Module brcmfmac does not exist in /proc/modules

        ERROR: Module bcma does not exist in /proc/modules
        update-initramfs is disabled since running on read-only media


    After getting the above, I tried:


    sudo modprobe -r b43 ssb wl brcmfmac brcmsmac bcma
    FATAL: Module ssb is in use.
    this@this:~$ sudo modprobe wl
    this@this:~$

    -----------------------------------
    I've also tried installing b43-fwcutter, but it isn't listed in Additional Drivers after my attempt.

    this@this:~$ sudo modprobe -r b43 ssb
    FATAL: Module ssb is in use.
    this@this:~$ sudo modprobe b43
    this@this:~$

    Any help would be much appreciated. Thanks. =)

    The Broadcom STA driver is incorrect for your device. Nice of Additional Drivers to offer you something that won't work, wasn't it? Hook up that ethernet for a few moments, open a terminal and do:
    Code:
    sudo apt-get remove --purge bcmwl-kernel-source
    sudo apt-get install linux-firmware-nonfree
    sudo modprobe -r wl && sudo modprobe b43
    Any improvement?

    Thanks for the speedy reply!
    Here's what I got from the terminal:

    this@this:~$ sudo apt-get remove --purge bcmwl-kernel-source

    Reading state information... Done
    Package 'bcmwl-kernel-source' is not installed, so not removed

    E: Unable to locate package linux-firmware-nonfree
    this@this:~$ sudo modprobe -r wl && sudo modprobe b43
    FATAL: Module wl not found.

    I'm not sure what's going on.. I think it has something to do with my using Ubuntu on a Live USB?

    I'm not quite sure how that could be. Are you connected to the internet? linux-firmware-nonfree is an available package in 12.10. Please try this:
    Code:
    sudo apt-get update
    sudo apt-get install linux-firmware-nonfree
    sudo modprobe -r b43 && sudo modprobe b43
    Off for the evening; see you tomorrow.

    Thanks so much for your help! I installed Ubuntu alongside WIndows 7, and followed your instructions. I had to restart my computer two times forcibly, but now under Additional Drivers, I have the linux-firmware-nonfree driver for a device known as "Unknown : Unknown." xP

    But I can now connect to wifi networks! Thanks again, I'm loving Ubuntu! =D

    Glad it's working! As I implied above, don't fret about Additional Drivers too much. Your wireless is working and that's what we needed.
