Strange enough – there are a lot of CLOSED SOURCE firmware out there – be it realtek or be it intel Wifi-Adapters.
closed source firmware is AGAINST truth and dignity…
Per default Debian will NOT install non-free firmware which is because of privacy reasons.
Vendors kind of “not care” about OpenSource community trying to avoid such firmwares?
steps to get going, unless you do not want Wifi…
0. identify your system
https://www.debian.org/releases/ -> here are all Version-Numbers and “Codenames” for that Version.
[cc lang=”bash” escaped=”true” width=”600″]
su; # become root
cat /etc/debian_version; # identify your version of debian
8.6 = Jessie
uname -a
Linux 3.16.0-4-686-pae #1 SMP Debian 3.16.36-1+deb8u1 (2016-09-03) i686 GNU/Linux
[/cc]
1. change sources.list to include non-free firmware
[cc lang=”bash” escaped=”true” width=”600″]
vim /etc/apt/source.list; # edit sources list
# at the end of the file put:
deb http://ftp.uni-erlangen.de/debian/ jessie main contrib non-free
deb-src http://ftp.uni-erlangen.de/debian/ jessie main contrib non-free
[/cc]
2. identify your network / wifi adapter:
[cc lang=”bash” escaped=”true” width=”600″]
apt-get install lshw; # install
lspci -knn|grep -EiA2 net;

3. search for what firmware package would need to be installed: https://duckduckgo.com/?q=linux+debian+firmware+Intel+Corporation+Centrino+Ultimate-N+6300&t=ffab&ia=web
http://forums.debian.net/viewtopic.php?t=59643
-> this kind of tells me, one needs to search for a package called “iwlwifi”
4. install the missing firmwrae
[cc lang=”bash” escaped=”true” width=”600″]
apt-cache search iwlwifi; # search for package
firmware-iwlwifi – Binary firmware for Intel Wireless cards
apt-get update && apt-get install firmware-iwlwifi; # install that package
[/cc]
if your adapter is realtek:
[cc lang=”bash” escaped=”true” width=”600″]
apt-cache search realtek; # search for package
flashrom – Identify, read, write, erase, and verify BIOS/ROM/flash chips
nictools-pci – Diagnostic tools for many PCI Ethernet cards
librtlsdr-dev – Software defined radio receiver for Realtek RTL2832U (development files)
librtlsdr0 – Software defined radio receiver for Realtek RTL2832U (library)
rtl-sdr – Software defined radio receiver for Realtek RTL2832U (tools)
firmware-realtek – Binary firmware for Realtek wired and wireless network adapters
apt-get update && apt-get install firmware-realtek; # install realtek firmware
[/cc]
5. install a network manager application (there is none installed per default under gnome2/MATE)
[cc lang=”bash” escaped=”true” width=”600″]
apt-get install network-manager-gnome; # for conveniently managing wifi connections from your MATE / Gnome2 Desktop
# when done do
reboot; # reboot system hardcore
[/cc]
you should have a nice icon in the upper right corner:
HAVE PHUN!
alternatively:
use unofficial non-free iso – that allready has the drivers on it. (Richard Stallman 
IS VERY MUCH AGAINST ANYTHING THAT IS NON-FREE) For good reasons of privacy… because after all a backdoor in your network card firmware could really compromise your system in terms of security and privacy.
Unofficial non-free images including firmware packages:
recommendation: ALWAYS GO FOR THE MINIMAL and load packages during setup straight from the internet…

Here are some extra images, equivalent to the normal images we produce regularly except in that they also include non-free firmware to make things easier on some systems requiring proprietary but redistributable firmware. See http://wiki.debian.org/Firmware for more details.
There are two types of image here:
- “netinst” install CDs that also include firmware to make installation easier
- live images including firmware packages pre-installed
The current and current-live directories contain images that match up with the latest stable Debian release.
