    Ubuntu 9.04 update broke wireless?


    I was running Ubuntu 9.04 on a new Dell Vostro 1520 for a few weeks.
    After the last group of patches (which I applied without reviewing) the
    wireless has gone ballistic. It will work initially when it boots, but it will
    eventually drop off and doesn't seem to come back.

    It worked flawlessly for the first few weeks before these latest patches.
    Is there a way to "undo" the applied patches in Ubuntu? Or is this issue
    known and have a possible work around?

    The problems most likely are caused by a change in the driver, that the update provided. To further troubleshoot this, much more info is needed. Please read the post linked to below. It tells how to find the needed info, and then post that info here.

    Of course, Murphy's Law, after I make the post the problem goes away.
    We'll see if it returns. Maybe the AP was just flaking out or something...

    There's a good chance that yet another update fixed the problem.

    I'm going to run through the Wireless Setup steps provided.
    I think another update came and now the wireless is toast.
    It doesn't even partly work, it just completely won't function.

    I wish there was an "undo updates" button, unless it's there
    and I'm just missing it...

    You can check to see if it is doing any automatic updates, and then disable it. Go to this:

    System-->Administration-->Update Manager

    Click on the "Settings..." button. There you can see and change the update settings. I have the "Only notify.." setting checked.

    We'll start with what you have. Here is the wireless card.
    Code:
    0e:00.0 Network controller [0280]: Intel Corporation Wireless WiFi Link 5100 [8086:4232]
    	Kernel driver in use: iwlagn
    	Kernel modules: iwlagn
    Here are the wireless and related modules loading.
    Code:
    Module                  Size  Used by
    iwlagn                100228  0 
    iwlcore                93184  1 iwlagn
    led_class              12036  1 iwlcore
    mac80211              217464  2 iwlagn,iwlcore
    cfg80211               38288  3 iwlagn,iwlcore,mac80211
    This wireless requires firmware to work, so it seems to be loading it.
    Code:
    [   23.408301] iwlagn 0000:0e:00.0: firmware: requesting iwlwifi-5000-1.ucode
    Everything appears to be in order. You can check to make sure that the firmware file iwlwifi-5000-1.ucode is in the folder /lib/firmware, or the kernel folders in /lib/firmware.

    To see if there are any other errors, you should post the entire out put of this command.
    Code:
    dmesg

    dmesg output broken up into 4 files and attached.

    $ ls -l /lib/firmware/*iwl*
    -rw-r--r-- 1 root root 149652 2009-04-02 16:46 /lib/firmware/iwlwifi-3945-1.ucode
    -rw-r--r-- 1 root root 149816 2009-04-02 16:46 /lib/firmware/iwlwifi-3945-2.ucode
    -rw-r--r-- 1 root root 187608 2009-04-02 16:46 /lib/firmware/iwlwifi-4965-1.ucode
    -rw-r--r-- 1 root root 187764 2009-04-02 16:46 /lib/firmware/iwlwifi-4965-2.ucode
    -rw-r--r-- 1 root root 345008 2009-04-02 16:46 /lib/firmware/iwlwifi-5000-1.ucode

    I notice that when I right-click on the networking icon...

    "Enable Networking" is active and checked.
    "Enable Wireless" is inactive (gray) and unchecked.

    I'm not sure if that signifies anything? I thought I recall it being active when the wireless was working previously.
