We're going to install the new kernel version from the PPA.

Open a terminal and type :

1. sudo apt-add-repository ppa:francisbrwn9/kernels
2. sudo apt-get update && sudo apt-get dist-upgrade
3. reboot

After rebooting, the Broadcom-STA (wl) driver doesn't work. We have to download the source from http://ftp.free.fr/mirrors/ftp.debian.org/pool/non-free/b/broadcom-sta/ :

broadcom-sta-common_5.100.82.112-6_all.deb
broadcom-sta-source_5.100.82.112-6_amd64.deb

In terminal, type :

1. sudo -s
2. dpkg -i broadcom-sta-source_5.100.82.112-6_amd64.deb
3. dpkg -i broadcom-sta-common_5.100.82.112-6_all.deb
4. m-a a-i broadcom-sta
5. update-initramfs -u -k $(uname -r)
6. modprobe wl
7. exit

Now you can use the WLAN0 interface.
