    Broadcom 4315: No wireless after upgrading to Pangolin 12.04

    Thank you to anyone who can help.

    I searched for a resolution in this forum for my specific driver, but didn't find one, and following the advice of numerous others who had this problem has failed to help, so far.

    I have a Dell Inspiron laptop 32-bit and upgraded Ubuntu to Pangolin 12.04, suddenly I have no wireless. I have a Broadcom STA driver, but when I try to activate it under "Additional Drivers" I get:

    "Sorry, installation of this driver failed.

    Please have a look at the log file for details: /var/log/jockey.log"

    When I go to settings/wireless it says, "Firmware Missing"

    Following instructions from Chili555 in a thread very similar to my situation, I opened a terminal window and entered:

    lspci -nn | grep 0280

    This is what I got:

    0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)

    I don't see a solution for "4315" on this forum, yet. Here is the thread I'm talking about, that's similar to my situation:

    I sincerely appreciate anyone who can help, please keep it simple as I'm not as much of a techie as you all, thank you!

    With a temporary ethernet connection, please do:
    Code:
    sudo apt-get install --reinstall bcmwl-kernel-source
    After it's done, do:
    Code:
    sudo modprobe wl
    If there is no error or warning, your wireless should be working.

    Re: Broadcom 4315: No wireless after upgrading to Pangolin 12.04

    Thank you for responding Chili555, I get error messages running the codes you recommended:

    1. Here is what I get after running the first command:

    (Reading database ... 562647 files and directories currently installed.)
    Removing pdvdlinux ...

    No apport report written because MaxReports is reached already
    Errors were encountered while processing:
    pdvdlinux
    E: Sub-process /usr/bin/dpkg returned an error code (1)

    2. And here's what I get when I enter the second command:

    FATAL: Module wl not found.

    When I upgraded to Ubuntu 12.04, I received an error message that Flash and pdvdlinux had not been installed, followed by successful installation of Flash; however pdvdlinux could not be installed, and when I use the Update Manager now, this is what I get:

    http://ubuntuforums.org/showthread.php?t=2053256

    Now I see pdvdlinux is showing up in the error message when I run the codes you recommended to get the wireless up?

    Thanks so much for your help!

    Re: Broadcom 4315: No wireless after upgrading to Pangolin 12.04

    I think you have to get your pdvdlinux problems solved first. I am not experienced with this package, but I'd probably remove it altogether:
    Code:
    sudo apt-get remove --purge pdvdlinux
    sudo apt-get update
    Then see if you can then successfully install bcmwl-kernel-source.

    Another error message when I tried to remove pdvdlinux, this is what happens when I enter the first code:

    Re: Broadcom 4315: No wireless after upgrading to Pangolin 12.04

    I fixed the problem with pdvdlinux:

    sudo gedit /var/lib/dpkg/info/pdvdlinux.postrm

    # Comment out the last three lines & save

    sudo gedit /var/lib/dpkg/info/pdvdlinux.postinst

    # Comment out the last three lines of this also & save

    sudo dpkg -P --force-all pdvdlinux

    sudo apt-get update

    sudo apt-get upgrade

    That took care of it... now I'm running the scripts you gave to fix the wireless and I'll post the resutls.

    Re: Broadcom 4315: No wireless after upgrading to Pangolin 12.04

    Here's what happens when I run the following codes:

    sudo apt-get install --reinstall bcmwl-kernel-source
    sudo modprobe wl
    I don't get any error messages, however the wireless isn't restored, in fact it has disappeared under Settings/Network completely; however under "Additional Drivers" it now says the Broadcom STA Driver is active, but not currently in use on this system (it was inactive before).

    I rebooted, that didn't help, but at least the update manager works again (after clearing pdvdlinux, above).

    When I run the second line of the code, nothing seems to happen, is that expected? Any ideas? Thanks again...

    Re: Broadcom 4315: No wireless after upgrading to Pangolin 12.04

    Let's look for any error messages:
    Code:
    sudo modprobe wl
    dmesg | grep wl
    Thanks.

    Re: Broadcom 4315: No wireless after upgrading to Pangolin 12.04

    There was nothing from the first code, but after the second code I got this:

    [ 143.757765] wl: module license 'MIXED/Proprietary' taints kernel.

    I hope we're getting warmer

    Re: Broadcom 4315: No wireless after upgrading to Pangolin 12.04

    I think we are very warm. There are two opinions about how to get this little jewel working:
    Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315]
    I think we know bccmwl-kernel-source is the wrong one. With the ethernet hooked up:
    Code:
    sudo apt-get remove --purge bcmwl-kernel-source
    sudo modprobe -r wl
    sudo apt-get install linux-firmware-nonfree
    Reboot and let us hear a good report.
