DRAFT - Installing Debian on Lenovo G50.... configuring wi-fi

Here is a temporany procedure to configure the wi-fi on your Lenovo G50.
First of all you need to install the correctly firmware.
Download it from here(firmware-realtek_0.43_all.deb) and install it giving:

dpkg -i firmware-realtek_0.43_all.deb

Then add to the sources list file the backports repository.
We are going to install a new kernel. No panic!!!
So open /etc/apt/sources.list file and add this line:

deb http://ftp.debian.org/debian wheezy-backports main contrib non-free

Then:

apt-get update
apt-get upgrade

I read that about 3.16, kernel starting to support the realtek_0.4* firmware family....

So after searching(apt-cache search) the last one available... install the

linux-image-3.16-0.bpo.2-amd64
and
linux-headers-3.16-0.bpo.2-amd64
giving these commands:

apt-get install linux-image-3.16-0.bpo.2-amd64 linux-headers-3.16-0.bpo.2-amd64 -t wheezy-backports

Now we need to reboot and to select in the boot menu the new installed kernel.

Now if all it's gone well our wifi card should be recognized.
