    Is your wireless working now? If so, we'll need to blacklist dell-laptop.
    thank you very much. It worked for me

    I have 11.04 as well.
    You see, every computer has a wireless switch, but some of them have it as a button, others have shortcuts on the keyboard. The shortcut for wireless connection can usually be seen on your computer manual. I have an Acer and its shortcut is FN+F3.
    You should try finding it there. If the switch is not the problem then you should continue trying rfkill or other commands on the terminal. But I'm new to Ubuntu so I can't help you with that.

    Re: wireless is disabled by hardware switch - natty 11.04

    This is what I had to do to get my dell studio 1537 working:


    plug network cable into wireless router to gain network access


    list hardware
    lspci -vnn | grep 14e4


    I was able to tell that my hardware was supported by the b43-fwcutter package. Learned this at the following site:


    http://linuxwireless.org/en/users/Drivers/b43


    Install b43-fwcutter package
    sudo apt-get install b43-fwcutter


    then I had to go to the SYSTEM SETTINGS > HARDWARE > ADDITIONAL DRIVERS
    and activate the driver. REBOOT.


    rfkill list


    0: dell-wifi: Wireless LAN
    Soft blocked: no
    Hard blocked: yes
    1: brcmwl-0: Wireless LAN
    Soft blocked: no
    Hard blocked: no


    lsmod | grep dell
    dell_wmi 12681 0
    sparse_keymap 13898 1 dell_wmi
    dell_laptop 13827 0
    dcdbas 14438 1 dell_laptop


    sudo rmmod -f dell_laptop


    sudo rfkill unblock all

    rfkill list
    1: brcmwl-0: Wireless LAN
    Soft blocked: no
    Hard blocked: no


    It works and thanks to the posters on this thread

    And don't forget to blacklist dell-laptop as mentioned earlier thread.

    This is driving me natty! er Batty!

    Dell 1501 + Kubuntu natty + maverick version of bcmwl-kernel-source installed.

    I've unblacklisted bcm43xx in blacklist.conf. Dell_laptop and dell-wmi are running at startup.

    sudo rfkill list says both hardware and software locked on dell-wifi
    if I do sudo rmmod dell_laptop I get a notification "Wireless activated" and rfkill list returns nothing. Unfortunately although I am able to tick wireless, no wireless networks show up and the wifi light doesn't turn on, even if I fn+f2.

    With the current version of bcm-kernel-source sudo rfkill list returns nothing. Killing dell_laptop still shows the same activation message, but there is no checkbox to turn on wirless.

    Halp!

    I've unblacklisted bcm43xx in blacklist.conf.
    That has nothing to do with anything. Please add to the blacklist.conf file:
    Code:
    blacklist dell-laptop
    Reboot and let us see:
    Code:
    rfkill list all
    iwconfig
    Thanks.

    None of the suggested solutions above worked for me. Eventually downgraded bcmwl-kernel-source to previous release as per bug below:-

    Reply #36 in https://bugs.launchpad.net/ubuntu/+s...wl/+bug/732677 worked for me.

    Dell Latitude D420


    lspci -nnk | grep -iA2 net

    This thread is a bit long in the tooth. Would you please start your own new thread? Post:
    Code:
    lspci -nn | grep 0280
    dmesg | grep b43
    Leave a link here and I'll be right there.

    I had same issue with Dell Inspiron 1120. Somehow, with disabling, reenabling it came back OK. I won't use the hardware button anymore. Thanks!
