    Broadcom BCM4313 does not work - Lenovo G560

    Hey there everyone, I am new to Ubuntu and Linux in general. I have installed Ubuntu 12.10 from the official website. I am running dual boot with Windows 7. My machine is a laptop Lenovo G560.
    At home I am getting Internet from a wireless router. I have no problems connecting to my wireless(did not install any drivers) but I can't seem to get wired connection working. When a plug the cable nothing happens, I do not get the usual arrows icon for wired connection. I get a message now and then about wired connection disconnected and nothing else. I have tried disabling/enabling wired/wireless connection and networking in general - nothing seems to work.
    As I am pretty much a newbie with Linux I apologize in advance for any missing crucial information you need to help me solve this. Whatever additional info you need I will be posting.

    p.s - I have tried to achieve wired connection at my friends house as well - same thing + wireless connects with no problem but there is no actuall Internet connection. Same thing happens in the dorm where I study and spend most of my time - cable doesn't work, wireless connects but there is no Internet.
    It seems as if I get Internet signal only at home and only through wireless.
    Windows 7 works fine everywhere.

    You can try the module brcmsmac instead of the proprietary STA-driver:

    Update this driver and its firmware via:
    Code:
    sudo apt-get install --reinstall linux-backports-modules-cw-3.6-precise-generic build-essential dkms linux-headers-generic
    wget http://media.cdn.ubuntu-de.org/forum/attachments/39/45/5007272-Broadcom_Firmware_fae7121.tar.gz
    sudo tar xvf 5007272-Broadcom_Firmware_fae7121.tar.gz -C /lib/firmware
    From here:
    http://forum.ubuntuusers.de/topic/le.../#post-5007272

    Unload and uninstall the driver:
    Code:
    sudo modprobe -rfv wl
    sudo apt-get remove --purge bcmwl-kernel-source
    sudo depmod -a
    sudo update-initramfs -u
    Load the other driver:
    Code:
    sudo modprobe -v brcmsmac
    You should copy/paste these commands

    I did a restart after this. On start up the wireless connected automatically. I switched it off and plugged in the ethernet cable. At first nothing, then I went to connections and clicked on Auto Ethernet. After few seconds it connected and the arrow indicators appeared as well. Thank you a lot!
    If it is not too much, would you explain exactly what we did and what caused this problem?

    The driver brcmsmac is already part of the kernel, but its firmware is outdated. We uninstalled the Broadcom-STA driver and updated the other driver and its firmware

    Re: Wired connection does not work - Lenovo G560

    When I go to Software sources>Additional drivers I see that I still use some Broadcom STA driver. Is this different from the Broadcom STA driver I uninstalled?

    Deactivate it there. It is already uninstalled.
