    Soft blocked: yes
    Hard blocked: yes

    what do i do
    Find out if you have dell-laptop or dell-wmi loaded:
    Code:
    lsmod
    Whichever on it is, unload it temporarily:
    Code:
    sudo modprobe -rf dell-laptop <---or -wmi
    sudo rfkill unblock all
    Does your wireless srping to life? If so, we'll make it permanent.

    hey chili555 , I would be highly obliged if you throw light on my problem which is the same as of other members here i.e., can't get my wireless to work.

    I ran some commands that you listed here & they gave me the following results:

    chaitanya@CHAITANYA-PC:~$ lspci -nn | grep 0280
    0c:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11a/b/g [14e4:4312] (rev 01)
    chaitanya@CHAITANYA-PC:~$ rfkill list all
    0: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no
    chaitanya@CHAITANYA-PC:~$

    This device requires firmware and there is a bit of controversy about the best way to do it. You will be our test pilot! Please get a temporary wired ethernet connection, open a terminal and do:
    Code:
    sudo apt-get install linux-firmware-nonfree
    sudo modprobe -r b43 && sudo modprobe b43
    Any improvement?

    Yes, I do have a wired ehternet connection. I ran the commands & here's the result:

    It's been more than 15 minutes & the cursor is stuck there in the WARNING line.

    This is symptomatic of a failed ndiswrapper installation. Let's check a few things:
    Code:
    ndiswrapper -l
    ls /etc/ndiswrapper
    cat /etc/modprobe.d/blacklist
    Thanks.

    hey thanx again for your reply, sorry for taking a bit time. Here are the results:

    chaitanya@CHAITANYA-PC:~$ ndiswrapper -l
    chaitanya@CHAITANYA-PC:~$ ls /etc/ndiswrapper
    chaitanya@CHAITANYA-PC:~$ cat /etc/modprobe.d/blacklist
    blacklist bcm43xx
    chaitanya@CHAITANYA-PC:~$

    Re: Broadcom BCM4311, Ubuntu 12.04

    chaitanya@CHAITANYA-PC:~$ cat /etc/modprobe.d/blacklist
    blacklist bcm43xx
    There is no such module:
    chili@Think410:~$ modinfo bcm43xx
    ERROR: modinfo: could not find module bcm43xx
    So you may as well remove the ineffective file:
    Code:
    sudo rm /etc/modprobe.d/blacklist
    Now let's unload and reload the driver and see if there are any informative messages in the log:
    Code:
    sudo modprobe -r b43 && sudo modprobe b43
    dmesg | grep b43
    Either your wireless will be working or dmesg will tell us why not.

    EDIT: I see you are getting excellent help from my friend Hadaka. Please continue with him.

    It's stuck there.
