Ok, I updated the bios of my laptop from A10 to A15.
Here is the output o 'sudo dmidecode -s bios-version && sudo dmidecode -s
bios-release-date'
A15
09/24/2014
Nothing has changed concerning the wireless interface, when running
kernel 3.16.0-25 wifi doesn't work, while it works perfectly when
running the old 3.13 kernel.
Here is the output from 'lspci -vvnn | grep -A 9 Network'
