    wireless light on keyboard keeps blinking

    Just installed Ubuntu and the wireless LED keeps blinking when I have a connection but if I disable it turns red like it should.

    Re: wireless light on keyboard keeps blinking

    I believe your wireless card uses the driver module iwlagn. Check with:
    Code:
    lsmod | grep iwl
    If it is indeed iwlagn, let's try a temporary fix:
    Code:
    sudo modprobe -r iwlagn
    sudo modprobe iwlagn led_mode=1
    Now does the LED behave as expected? If so, let's write a simple file to make it permanent:
    Code:
    sudo gedit /etc/modprobe.d/iwlagn.conf
    Add one line:
    Code:
    options iwlagn led_mode=1
    Proofread carefully, save and close gedit.

    You should be all set.

    The LED blinks to show send-receive activity in addition to wireless on-off.

    What do you mean by "work as it should?" Isn't that what you want, Doc?

    I do, and many of us do, but many others are offput by the incessant blinking (nagging? sorta like my ex??) and would prefer a simple ON if the wireless is connected and OFF if it's not. The developers of iwlagn and a few other wireless drivers give us the option to select.

    If he were using most other drivers, I would have said, "I can do nuthin' fer ya, son."

    A great place to start with driver issues is:
    Code:
    modinfo <your_driver>
    In this case:
    Code:
    $ modinfo iwlagn

    Worked like a charm. Thank you for the help.

    Thanks man! One more "feature" of 11.10 that is no longer bugging me.

    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.
