    Question Unclaimed wireless network controller after update on 12.04

    Hi, I'm haivng the same problem as this post:

    http://ubuntuforums.org/showthread.php?t=2206487

    After I installed the new kernel update and restarted, i couldnt use my wireless anymore.
    Because I am new to linux and ubuntu, I am not totally sure what to do, if I need to install a driver or what driver to install.

    This came up when i did the lshw -c command:

    *-network

    Re: Unclaimed wireless network controller after update on 12.04

    And did you have this part as well?
    I had to install some kind of special patch for the kernel when I first installed this version of Ubuntu on my laptop a couple of months ago because it had the same problem
    What does this tell us?
    Code:
    modinfo iwlwifi | grep 7260
    ls -al  /lib/firmware | grep 7260
    Thanks.

    I installed the kernel patch right before this problem. When I first installed Ubuntu there didnt seem to be a kernel patch.

    Here is what I got from the code:

    firmware: iwlwifi-7260-7.ucode


    7260 there is in red...

    Re: Unclaimed wireless network controller after update on 12.04

    However, if the modinfo step doesn't produce any result, then the driver doesn't claim your device. I suggest you download this to your desktop: http://www.kernel.org/pub/linux/kern....13.2-1.tar.xz Right-click it and select 'Extract Here.' Now open a terminal and do:

    Code:
    cd ~/Desktop/backports-3.13.2-1/
    make defconfig-iwlwifi
    make
    sudo make install
    Reboot and tell us if it's working as expected.

    Let's see:
    Code:
    modinfo iwlwifi | grep -e version -e 7260
    sudo modprobe iwlwifi
    dmesg | grep iwl
    Were there errors, warnings, etc., as you compiled the package?

    I didnt see any warnings or errors before no.

    Here is the result of that:

    It looks like there is a problem with the firmware. May I now see:
    Code:
    ls -al  /lib/firmware | grep 7260
