My Network Driver is Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) via lspci.
HOW TO INSTALL A PRE-COMPILED DRIVER
Some of the major linux distros already supply a version of this driver, so
you don’t have to compile your own. Most of the distros keep this driver
along with other proprietary or non-GPL drivers in a separate repository.
For further information see the documentation for your specific distro.
Fedora:
su -c 'rpm -Uvh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm' su - yum update yum install kmod-wl
Ubuntu:
Go to System->Administration->Hardware Drivers
Choose the Broadcom STA wireless driver
Activate
Sometimes the driver does not show up in the Hardware Drivers choices. In
this case, try reintalling the driver from the GUI or shell like this:
From the GUI:
Package Manager (System>Administration>Synaptic Package Manager). Click the
Reload button in the upper left corner of Synaptic to refresh your index then
search for and reinstall the package named bcmwl-kernel-source.
From the shell:(recommend)
sudo apt-get update sudo apt-get --reinstall install bcmwl-kernel-source
In either GUI or text case, after reinstalling, reboot your machine.
Now go back to System->Administration->Hardware Drivers
and you should see the driver enabled and working.
