    Re: wireless is disabled by hardware switch - natty 11.04

    With My Inspiron 1501, I'm also seeing this bug where the wireless is hardblocked. To complicate matters, I'm having a problem in that the keycode for the wireless button [Fn-F2] isn't mapped.
    Code:
    May 10 17:14:51 ubuntu-dell kernel: [  191.862248] kbd_keycode: 15 callbacks suppressed
    May 10 17:14:51 ubuntu-dell kernel: [  191.862257] keyboard: can't emulate rawmode for keycode 240
    May 10 17:14:51 ubuntu-dell kernel: [  191.862296] keyboard: can't emulate rawmode for keycode 240
    Any suggestions?

    Code:
    sudo rmmod -f dell-laptop
    sudo rfkill unblock all
    Is your wireless working now? If so, we'll need to blacklist dell-laptop.

    Did anything improve after you removed dell-laptop?

    Thanks for the pointer, but no, I have already removed it. No joy.

    This is a real backward step from 10.10 and many previous versions on this Dell hardware. I recall having these kinds of keycode problems three or four years ago (7.04 or 7.10 IIRC) with an Acer laptop, but not with this hardware.

    sudo rmmod -f dell-laptop


    Question: Not to sure but is it removed? Looks like the command should be.

    Code:
    sudo rmmod -f dell_laptop
    Well I thought it might not work BUT I was WRONG.... Checked it and sudo rmmod -f dell-laptop
    worked just fine...

    Meaning the wireless works just fine without dell-laptop? If so, we can blacklist it.

    That seems logical to me... However I just removed the module and then restarted it here.. It has no adverse effect on my laptop but I am not having the OP's issue. I was just curious as to what it might do..

    Let me rmmod it again and reboot .. Dang I like testing LOL

    If you reboot, the rmmod disappears. I think you need to do:
    Code:
    sudo rmmod -f dell-laptop
    sudo rfkill unblock all
    Do NOT reboot. Is your wireless working?

    chili555 I was just testing my laptop to see if it would reboot after blacklisting the dell_laptop module. And yes it did without any rfkill commands.

    lsmod | grep dell

    Code:
    bigdad@bigdad-Latitude-D620:~$ lsmod | grep dell
    dell_wmi               12601  0 
    sparse_keymap          13666  1 dell_wmi

    If you want to make it permanent, do:
    Code:
    sudo su
    echo "blacklist dell-laptop" >> /etc/modprobe.d/blacklist.conf
    exit
