Installing Broadcom Wireless Drivers for "Chip ID": BCM4360, "PCI-ID": 14e4:43a0 (rev 03) on Ubuntu 14.04

Solution 1:

AFAIU, bcmwl-kernel-source is correct, so I suggest you reinstall it:

sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl

Now check the logs for informative messages:

dmesg | grep wl

It appears that, although you have a 3.16.0-xx kernel (thanks, @Jeremy31!), apt has tried to install the version for Ubuntu 14.04. I suggest you remove the version that failed to install:

sudo apt-get purge bcmwl-kernel-source

Download these packages to your desktop: http://packages.ubuntu.com/utopic/bcmwl-kernel-source and also: http://packages.ubuntu.com/utopic/dkms Be sure to get the 32- or 64-bit version as needed. Find out with:

arch

For example, if it returns x86_64, then you need the 64-bit version; known at packages.ubuntu as amd64.

Install the packages with:

cd ~/Desktop
sudo dpkg -i *.deb
sudo modprobe wl

Again, note and post any errors.

Solution 2:

While chili555 answer worked for me, I reinstalled Ubuntu and then discovered an alternative method to the same solution. This requires an active connection to the Internet.

• Open System Settings > Software & Updates > Additional Drivers
• Select "Using Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernel-source (proprietary)"
• Apply changes

Restart is required, although it worked without restarting.
