    WIFI issues Broadcom

    Hello dear All,

    I am absolutely lost and I would like to ask advise. After upgrading to Ubuntu 12.04 my Broadcom WIFI driver stopped working.
    I tried ndiswrapper with a windows driver, I also tried activating the driver as in previous comments, I tried also different distributions, but the driver is not active and wifi is not working. My expert friend also blacklisted the driver and reactivated, but no change.

    These are the details:
    Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)

    It shows : wireless disabled by hardware switch. However I triple checked and the physical switch in ON. I switched ON/OFF not working. On some distros it is not even showing this, it just not showing any wireless options.
    Else : networking works fine from ethernet cable and 3G stick.

    Does anybody have any idea??
    THANK YOU IN ADVANCE.

    Uninstall ndiswrapper as it will prevent anything else working and is pretty much superseded by b43.

    Did you do an update with the ethernet cable in? If not, uninstall ndiswrapper and do that, then check Additional Drivers.

    If there's nothing there, try installing b43-fwcutter and firmware-b43-installer.

    You may need to log out or restart to get the changes to happen.

    Hi ,
    the wireless card you have is supposed to work out of the box in 12.04 . You not need any restricted drivers and especially you don't need this ndiswrapper.

    Please follow bellow commands to remove completely this ndiswrapper thing

    Code:
    sudo modprobe -rf ndiswrapper 
    sudo apt-get remove --purge ndiswrapper-common ndiswrapper-utils-1.9 ndisgtk sudo rm /etc/modprobe.d/ndiswrapper.conf 
    sudo rm -r /etc/ndiswrapper/*  
    sudo depmod -a
    Then take a look here => http://ubuntuforums.org/showthread.php?t=1985698

    Re: WIFI issues Broadcom

    hello!! thank you.

    ndiswrapper is removed as I am currently on a brand new installation of Mint.

    I tried the code what suggested on the attached link:, and this was returned

    0: ideapad_wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
    1: ideapad_bluetooth: Bluetooth
    Soft blocked: yes
    Hard blocked: no
    2: brcmwl-0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes

    What exactly is Hard blocked: yes means? Can it mean that my physical switch might be faulty? It is switched on for sure..

    Re: WIFI issues Broadcom

    Hard blocked means that wireless is of , but maybe we have a conflict here. (like the other thread I gave you).

    Let us see some extra info.

    Please open a terminal (CTRL+ALT+T) and execute bellow commands with order. (Active Internet connection required)

    Code:
    wget "http://ubuntuone.com/1kKCgeRTZHszxUdsSEekYz" -O ~/wirelessinfo
    chmod +x wirelessinfo
    sudo ./wirelessinfo
    The last command will produce a file named netinfo.txt inside your /home folder.
    Click on "New Reply" and attach the file. See here on how to attach a file

    Re: WIFI issues Broadcom

    You have this wl driver installed and enabled. This is the additional driver . Try to remove it.

    Code:
    sudo apt-get remove --purge bcmwl-kernel-source
    Then reboot and check the wireless again.

    If not working , give the results of
    Code:
    lspci -nnk | grep -iA2 net 
    lsmod
    dmesg | grep -ie net -ie firm -ie b43 -ie wlan -ie eth

    Hello,
    after removal and reboot, the wireless is still disabled, no reaction on anything.

    Re: WIFI issues Broadcom

    Hi ,
    try this
    Code:
    sudo modprobe -rvf bcma
    sudo modprobe -rvf brcmsmac
    Then do
    Code:
    sudo modprobe brcmsmac
    See if wireless works. If yes we have to make it permanent because above is for one session only.

    Thanks
