    Default wlan0 No Longer Working

    Hey guys,

    So I have been having this problem with my WiFi which isn't working. I am currently running on the following:
    uname -a
    Code:
    Linux mmartin6510 2.6.31.14-0.8-desktop #1 SMP PREEMPT 2011-04-06 18:09:24 +0200 i686 i686 i386 GNU/Linux
    I am also using gnome-NetworkManager. If I left-click on the NetworkManager icon down on the taskbar near the clock it shows "Wired Networks" with eth0 connected, and "Wireless Networks" is blank under the heading, last week I believe it said something like "device unavailable" or something like that.

    Network Details:
    iwconfig

    I was curious about when the last time I was able to successfully use my wifi so I checked to see in NetworkManger and it just so happend to be that I was on a business trip in Atlanta on a different network then am usually connected to. Don't know if that has to do with anything but I thought it was worth mentioning.

    If I could supply any other info to you that would help, please let me know, and include the command to get it.

    Also, I thought it may have something to do with assigning an IP address static-or-auto but I am not too familiar with NetworkManager to check that.

    Thanks,
    Matt

    Have you checked out either of these two stickies on the wireless section of this forum?

    No I haven't I'll check it out, thanks...

    Default Re: wlan0 No Longer Working

    Ecky,

    So I checked out that first link you had up there, which is a great resource btw, thanks for that.
    So the dmesg and grepping for firmware led me to find that my laptop is not able to load the correct firmware. So I went to /lib/firmware and noticed that the ucode file is missing and I cannot seem to find it on the Intel website. Do you know where I can locate the correct file? It says I need "iwlwifi-6000-3.ucode" or 2 or 1. But the only one I can find on their site is iwlifi-6000-4.ucode, would this do anything for me?

    Thanks,
    Matt

    I tried installing suse and upgrading to gnome 3 last night, my wireless worked at first, and after upgrading I had the same issue as you with the wireless (in addition to gnome shell crashing when I clicked applets in the panel) I also have intel wifi. Could there be a bad update?

    Default Re: wlan0 No Longer Working

    After searching for hours and hours I have not found a single answer to this problem. And cannot find a single download for iwlwifi-6000 version 3.
    Does anyone know anywhere I could find this firmware???

    Install the kernel-firmware package using YaST or zypper.

    Hey lwfinger,

    Thanks for the response. I re-installed the kernel-firmware like you said, did it through Yast Software Management. Rebooted and still nothing. The ucode file it is looking for is still missing in /lib/firmware.

    Code:

    I have only been able to find iwlwifi-6000-4.ucode anywhere on the Internet and am still getting the error. I also tried downloading the one for 6000 v4 and just creating a link that points to that one but then it tells me that it is the wrong version.

    In YaST I also saw ipw-firmware which is currently installed. I may try to re-install that and see if that does anything.

    Thanks for the suggestions,
    Matt

    There is a package available in yast's software manager called iwl6000-ucode, don't know if you have it installed, if not maybe that one will work for you?

    Version 3 though seems to be pretty old as the one I found in software manager is version 9 and a google on it finds a lot of people having problems with the same device that relates to driver backwards compatibility

    Curiously a read on some of the results I found showed that some people fixed it using a backport while others fixed it with an update, sounds like a bit of a paradox but maybe backwards compatibility with your device version wasn't working in one or more driver versions between v3 and the later ones, has to be worth trying it if you don't already have it installed

    You will need the link between iwlwifi-6000-3.ucode and iwlwifi-6000-4.ucode.
    According to an expert on the linux-wireless mailing list, older versions of the
    firmware can be obtained at http://intellinuxwireless.org/?n=downloads. Try
    progressively older versions until you find one that works.

    Please report back what actually solves the problem. I'm sure the situation will
    happen again. If it is not possible to find one that works, then I would suggest
    installing the compat-wireless package. The firmware in the iwl6000-ucode
    package should match that driver. Unfortunately, I do not have such a device and
    cannot test the possible solutions.
