    Re: wireless light on keyboard keeps blinking

    I am using Ubuntu 11.10 on Dell D630 laptop with Intel's 4965 network card.
    I have tried the above but it has not worked for me (I am quite novice at coding in Ubuntu).

    After coding for
    sudo gedit /etc/modprobe.d/wlan.conf
    and saving the following in the text editor
    options iwlagn led_mode=1
    I get the following error message in terminal:

    (gedit:2295): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', but failed: Failed to create file '/root/.local/share/recently-used.xbel.6AC66V': No such file or directory

    (gedit:2295): Gtk-WARNING **: Attempting to set the permissions of `/root/.local/share/recently-used.xbel', but failed: No such file or directory
    I hope someone has a solution

    sudo gedit /etc/modprobe.d/wlan.conf
    I believe your card uses not iwlagn but iwl4965. Please verify:
    Code:
    lsmod | grep iwl
    The module iwl4965 does not have an LED parameter, unfortunately.

    Re: wireless light on keyboard keeps blinking

    Yes, my wireless driver is iwl4965.

    I only happen to have this issue on Ubuntu 11.10. I have Win7 (dual boot) and don't have any issues. The led indicator is lit up when the wifi connection is on and when it is not, it's off.

    I have never seen the blinking before and it is distracting when I try to work, so I would highly appreciate any assistance

    Thanks again

    Please try this:
    Code:
    sudo mkdir /root/.local/share/
    sudo gedit /etc/modprobe.d/iwl-legacy.conf
    Add one line:
    Code:
    options iwl-legacy led_mode=1
    Proofread carefully. Save and close gedit. Now do:
    Code:
    sudo rm /etc/modprobe.d/wlan.conf
    Reboot and let us have your report.

    There was a time, in the world of *nix, when one did not release programs or libraries without man-pages. Notice that there are such pages for much of the C-language (now C++) run-time-library. Would it be that much trouble to write a man-page such that man module-name would report details about available parameters and their meaning and usage, caveats about use of the module, dependencies on other modules, and so on?

    When I was coding for a living, we wrote these man pages first while writing the implementation requirements. They later served as input into unit test planning and sometimes code specification.

    I lament, also, the proliferation of command line software that does not implement options that are defacto standard such as --help and --version and the short-form equivalents -h or -?, and -v.

    One would think not, however, there doesn't seem to be any. I had hoped there might be available published data sheets from the manufacturers explaining all this, but have not found it so far.

    I have sometimes found sparse documentation in the form of comments in .c files; for example, here:
    Code:
    less /usr/src/linux-source-2.6.38/drivers/net/wireless/iwlwifi/iwl-3945.c
    For me, at least, it's a combination of trial and error, educated guess-work and...luck. Sorta blows the Doctor image, doesn't it!

    PS - Dependencies are well covered in modinfo module-name.

    This worked for me, THANK YOU VERY MUCH.

    EDIT: sudo mkdir /root/.local/share/ already existed.

    Re: wireless light on keyboard keeps blinking

    I would just like to add to the solutions here:

    LINK: https://alexcabal.com/stop-blinking-...ubuntu-karmic/

    Solution that worked for me : echo "echo \"options iwlwifi led_mode=1\" >> /etc/modprobe.d/iwlwifi.conf" | sudo bash

    I tried the above steps in this post and did not work for me but i did find the site and it worked. So i figured id share this with yall.

    For those that have found this old thread (comes up high in search results) while desperately seeking a solution...

    I'm currently doing +1 testing on Ubuntu 14.04 LTS. Sorry to report this, but the blinking LED light problem still exists.

    Supposedly (according to posts on Launchpad) this 'problem' is actually a kernel feature. Whatever.

    I own a Dell Latitude D620. The LED light doesn't blink on Ubu 14.04 with a Linux 3.13-rc2 kernel.

    I also own a Dell Latitude D630 ATG. The LED light DOES blink on Ubu 14.04 with a Linux 3.13-rc2 kernel.

    The difference between these two laptops is:

    • The Dell D620 has a Dell Wireless DW1390 mini-card (no blinking)
    • The Dell D630 ATG has an Intel Wireless Pro 3945abg mini-card (non-stop blinking)


    The 'fix' for the D630 was to swap its 3945 wifi card with the 1390 wifi card from the D620.

    Put another way, the 3945abg blinks, and the 1390 doesn't.

    Hopefully, somebody will find this helpful.

    BTW, I just bought a new 1390 on Ebay for $3.00 with free shipping. I'll put it in my D620 and throw the 3945 on the junk pile.

    Problem solved...
