I used the netdisk iso to install debian, which apperently is missing the firmware files: rtl_nic_rtl8411-2.fw and iwlwifi, so I can't get my wifi working. My laptop uses intel wireless-AC 8260, and I have updated my kernel to 4.8
Dmesg output:

I'm not sure if I have installed iwlwifi 8000 correctly. this is my /lib/firmware output.

I have copied the non-free sources into my /etc/apt/sources.list
deb http://ftp.us.debian.org/debian/ jessie main contrib non-free#
deb http://mirror.one.com/debian/ jessie-backports main contrib non-free
When I do apt-get iwlwifi:
firmware-iwlwifi is already the newest version.
I have tried to get this working for 2 days now without luck, what am I missing? I'm new to Linux so I'd really appreciate an understandable answer for a beginner.
Download iwlwifi-8000C-24.ucode from https://github.com/NetBit73/NeteXt73_pakiety/tree/master/iwlwifi
The package that you are missing is firmware-iwlwifi which is a non-free package. The official Debian image builds only includes Free Software.
Method #1 - with ethernet connection
So to install it you need to add the non-free and contrib components to /etc/apt/sources.list
See: https://wiki.debian.org/SourcesList#Example_sources.list
Then,
sudo apt-get update
sudo apt-get install firmware-iwlwifi
Method #2 - with no Internet connection
Manually download (from some other machine with Internet connection) the deb package for your release from here.
If you're using the Debian stable, check: https://packages.debian.org/stable/firmware-iwlwifi
Then,
dpkg -i firmware-iwlwifi*.deb
Restart.
The same process should work for Realtek drivers.

I suffered this problem for a week and did not know how to fix it. After many tests, I discovered that my Kernel (3.10) was not compatible with the firmware as say the next web: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi The Kernel versión you need is: * 4.1+ for iwlwifi-8000-ucode-25.30.13.0.tgz (Intel® Wireless 8260 and 4165) * 4.3+ for iwlwifi-8000-ucode-16.242414.0.tgz (Intel® Wireless 8260 and 4165) * 4.6+ for iwlwifi-8265-ucode-22.361476.0.tgz (Intel® Wireless 8265) I updated from 3.10 to 4.6 and my problem was solved for my Intel 8260 Dual Wireless/WiFi card. I hope this helps someone. Cheers!

If your card works, its just a information message from Kernel :

As you can read in the README for iwlwifi-firmware package :
- OVERVIEW
The files iwlwifi-8000C-16.ucode provided in this package must be present on your system in order for the Intel Wireless WiFi Link AGN driver for Linux (iwlwifi) to operate on your system.
The "-16" in the filename reflects an interface/architecture version number. It will change only when changes in new uCode releases make the new uCode incompatible with earlier drivers.
On adapter initialization, and at varying times during the uptime of the adapter, the microcode is loaded into the memory on the network adapter. The microcode provides the low level MAC features including radio control and high precision timing events (backoff, transmit, etc.) while also providing varying levels of packet filtering which can be used to keep the host from having to handle packets that are not of interest given the current operating mode of the device.
