Install the firmware (#4):

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

Reboot and check:

dmesg | egrep 'bcma|brcm'
iwconfig
lsmod
sudo iwlist scan

[sushi80]

still not working!

Driver update as mentioned in #4?

[rodolphoarruda]

Hi all,

After some investigation I have managed to solve the issue on my G460 running ubuntu 12.04.

What causes the issue is that Ubuntu detects BCM4313 and applies Broadcom's "wl" driver to it. You can certainly do some web surfing, but will face some of the problems listed here along the thread. According to Broadcom's website, BCM4313 can use either "wl" or "brcmsmac" drivers, but in order to solve ALL the wireless issues you must drop the former and use the latter.

Follow the steps below:

Run this command to check whether we are in the same page, talking about the same pieces of hardware here:

lspci -nnk | grep -iA2 net

If you got output with things like these below, go ahead. If you didn't, stop here, this solution won't help you.

- Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller
- 14e4:4727
- brcmsmac

Now you are going to need git. If you don't have it installed on your machine yet, do it so. Type in the command below. It's going to ask for your password to proceed.

sudo apt-get install git

Once git is installed, go to this URL to see from where you are getting files from (it's just FYI only):

https://git.kernel.org/cgit/linux/ke...-firmware.git/

Now run this command:

git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

Git will clone the set of files (called repo) into your home folder. Go there and copy the following files:

brcm/bcm43xx-0.fw
brcm/bcm43xx_hdr-0.fw

Now you have to open Nautilus as root user in order to paste them some where else protected in your system. Run the code below and wait until Nautilus window pops-up.

sudo nautilus

Paste the two files above into here:

/lib/firmware/brcm

At this point we are almost done. Now we need to remove "wl" and make Ubuntu use the new driver, "brcmsmac". For that, run the code below. WARNING: since we are swaping drivers, there will be a "shadow" period where your machine will be without wireless at all. Do not panic. As soon as the system gets the new wireless driver, things will be back to normal... or... to what they should have been since installation.

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

Finally, run this command to wrap things up around the new driver:

sudo modprobe -v brcmsmac

Done! Now you should be able to enjoy wifi like everybody else. Cheers!
