I update my Toshiba PORTÉGÉ from Precise(12.04) to Quantal (12.10). After update to Precise wireless device works fine. But after update wireless device is not detect on network manager.

The lspci command says:

The ethernet connection works fine. I try to install firmware-b43-installer but it says:

$ sudo apt-get install firmware-b43-installer

I execute this too and this is the output:

I have checking the model in http://linuxwireless.org/en/users/Drivers/b43:

BCM4313 - chipset uses unsupported LCN PHY, we work on it

I had configured privated drivers in the visual enviroment, Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernel-source but don't work either.

I believe bcmwl-kernel-source is correct for your device. Let's try again:

sudo apt-get install linux-headers-generic
sudo apt-get install linux-headers-$(uname -r)
sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl

You should be all set.

  • thanks for you answer, but it doesn't work. I reinstall the bcmwl-kernel-source but no wireless module is founded: sergio@caprica:~$ sudo modprobe wl FATAL: Module wl not found. FATAL: Error running install command for wl

  • For the 3.8 kernel now with 12.04.3 this will fail to compile. See askubuntu.com/a/337999/88802 for the workarounds.

On the upgrade from 12.x to 13.04, the old bcm43 module got blacklisted, however on my mac-mini, the b43 (free driver) was already blacklisted.

Especially for people having used the non free driver in 12.x, this becomes a problem, as the b43 is also blacklisted under 12.x there. So - we have 2 bcm43 and b43 both blacklisted, and none will work. So - check the /etc/modprobe.d directory for any b43 and bcm43 entries, and make sure only one gets blacklists.

YYMV - but I found the bcm43 non free to provide better performance
