Broadcom BCM4313 does not work - Lenovo G560

[chaushev]

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:

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:

sudo modprobe -rfv wl
sudo apt-get remove --purge bcmwl-kernel-source
sudo depmod -a
sudo update-initramfs -u

Load the other driver:

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?

[praseodym]

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

[chaushev]

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?

[praseodym]

Deactivate it there. It is already uninstalled.
