Ubuntu – Broadcom Corp. BCM4313 Wirelss not detected in Ubuntu 12.10


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.

Best Answer

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.
