Wireless not working after installing Ubuntu 13.04

[JesUbik]

So my network connection is not working at all after formating my computer and installing Ubuntu 13.04.

Before formating, I was using Windows 7 in one partition and Ubuntu 12.04 in another. I installed windows first and had to download some drivers to have network, video, etc, working properly. And Ubuntu 12.04 automatically had everything working by itself.

So I formated my computer, installed Ubuntu 13.04 and can't setup the internet connection.

Here is the output for ifconfig in terminal:

Also, I checked for the drivers at Software and Updates and it looked like that:


Software and updates > additional drivers >


Broadcom corporation: BCM4313 802.11b/g/n Wireless LAN Controller
(this device is using an alternative driver
Using Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernel-source

I know that this is probably a very begginer question but english is not my native language and I've been searching for solutions in this very old and small netbook.

Does any of you know how to get it working, please?

Thank you (:

Hi,

uninstall the STA driver and its config via:

sudo apt-get remove --purge bcmwl-kernel-source
sudo rm /etc/modprobe.d/blacklist-bcm43.conf
sudo rm /etc/modprobe.d/broadcom-sta-common.conf
sudo rm /etc/modprobe.d/broadcom-sta-dkms.conf

Download this firmware file and save it in "Downloads".
http://media.cdn.ubuntu-de.org/forum..._070513.tar.gz
Installation via:

sudo tar ~/Downloads/xvf 5007272-Broadcom_Firmware_070513.tar.gz -C /lib/firmware

Shutdown for 10 minutes currentless and reboot.

Thank you for the quick anwer, praseodym.

So I was able to uninstall the STA driver with the first command line. But couldn't perform the rest of it.

This is the output:

jessica@jessies-SpaceShip:~$ sudo rm /etc/modprobe.d/blacklist-bcm43.conf

Sorry typo:

sudo tar xvf ~/Downloads/5007272-Broadcom_Firmware_070513.tar.gz -C /lib/firmware

is the right command

[JesUbik]

Ok! Installed it!

But Ubuntu keeps not turning wifi on... Maybe is there something about my broadcom BCM4313 board?

Thank you very much (:

Any button/switch/key/key combination? Try also:

sudo rfkill unblock all
rfkill list

I don't have any switch... just F2 for turning wifi on or off but it seems not to work with Linux

[JesUbik]

HA I can see avaliable wifi networks!
