    Exclamation Toshiba L640 Wireless BCM4313 Not Working UBUNTU 11.10

    I also have a HP Laptop which has BCM4311 and getting Wifi to work on it was easy simply had to disable Broadcom STA Driver install firmware-b43 and Reboot

    I have a Toshiba L640D having BCM4313 Wireless card.

    First thing I tried was the above Troubleshooting. Also read the
    BCM4313 solved thread stating to "blacklist bcma" but it didn't work. Only progress achieved so far is that it detects the Wifi Connection asks for Security Key but is never able to connect.

    SOLUTION
    Did some hit and trial and finally got my BCM4313 to work.
    None of the Previous threads directly related to BCM4313 helped so here I am mentioning my steps.

    Firstly went over to Synaptic Package Manager
    >Remove all the Installed Packages related to BCM & BCM 43 // Do check STA in Additional Drivers is deactivated if not please do so before Removing Packages

    >Then check whether bcma is blacklisted ( in file /etc/modprobe.d/blacklist.conf ) if not then type in terminal
    Code:
    echo "blacklist bcma" | sudo tee -a /etc/modprobe.d/blacklist.conf
    >Similarly check whether brcm80211 is blacklisted ( in file /etc/modprobe.d/blacklist.conf ) if not then type in terminal
    Code:
    echo "blacklist brcm80211" | sudo tee -a /etc/modprobe.d/blacklist.conf
    >Reboot

    >Goto Synaptic Package Manager
    In search simply type bcm43 ( to easily find all the Packages required to install )
    Select the Following Packages for installation ( latest version )
    1)bcmwl-kernel-source
    2)broadcom-sta-common
    3)broadcom-sta-source
    4)firmware-b43-installer

    It will prompt for additional packages required simply accept them too.

    >Reboot

    This time round No Wifi is being displayed in the Network Section and if you check
    Code:
    rfkill list
    It also won't be displaying the wifi card will display bluetooth only ( if any )

    >Goto Additional Drivers
    Activate Broadcom STA

    By now your Wireless would be active and ready to connect but still on the safer side

    >Reboot

    Now if you check Synaptic firmware-b43-installer won't be marked as installed // Mentioning just in case you face with any problems can apply your own Hit and trails.

    Sweet!

    I've got an hp-2000 with a bcm4314 and this worked perfectly for me (as some other suggestions did not).

    Just one question. Why do you have to install the broadcom-sta-source?

    Re: Toshiba L640 Wireless BCM4313 Not Working

    To the OP, I have a BCM 4313 and did all the steps as you mentioned. When I check rfkill after reinstalling packages, it still shows me wireless lan and under that soft blocked and hard blocked.

    Code:
    0: ideapad_wlan: Wireless LAN
    	Soft blocked: no
    	Hard blocked: no
    1: ideapad_bluetooth: Bluetooth
    	Soft blocked: yes
    	Hard blocked: no
    OP mentions, we should only see the bluetooth list. That is not the case with me. Perhaps, that's why it still ain't working. Any suggestions?

    Hello there,

    Thanks for the solution it worked fine in a HP Pavilion dm4 with a BCM4313.

    I had tried several ways to fix it before and they just dind't work. This is the simpler and straight forward solution I have found and it works!!

    Cheers.
    Javier.

    Hi lossman,

    I am facing a similar problem as yours. I assume that you have fixed it as it has been quite some time since this message has been posted. Can you help me out in solving it please.


    Hi OP,

    Can you also guide me what to do, my rfkill list gives the exact 6 lines which lossman has just mentioned.

    Just FYI: this worked for me with Ubuntu 12.04 LTS on a Dell Latitude E4200 with Broadcom Corporation BCM4312 wireless card.

    Re: Toshiba L640 Wireless BCM4313 Not Working

    Many thanks jskandhari, this (post #2) has worked for me. (Acer Aspire 5741 laptop containing Broadcom BCM43225 wireless)

    My problem started after upgrading from 11.10 to 12.04, after which all references to wireless networks had disappeared from the drop-down 'Network Menu'. Although 'Broadcom STA proprietary wireless driver' was listed under 'System Settings...' > 'Additional Drivers', it was not activated, and pressing the 'Activate' button produced the error "Sorry the installation of this driver failed. Please have a look at the log file for details: /var/log/jockey.log"

    I didn't have to follow your instructions to the end before my wireless started working again as the Broadcom STA activated automatically at the second re-boot (directly following the package re-install).

    Thank you!
