I can't get my WLAN working on a fresh Debian 8.7.1 64bit installation. Maybe you can help me find the issue. The card I am using is an Intel 8260 WLAN/Bluetooth card:

# lspci | grep Wire
04:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a)

I installed iwlwifi with apt and loaded the module:

# modprobe -r iwlwifi ; modprobe iwlwifi

lsmod output:

# lsmod | grep wif
iwlwifi                96547  0
cfg80211              413730  1 iwlwifi

iwconfig:

# iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

So what am I missing?! I am getting the feel it's because of the firmware not supporting the Kernel?

root@dfog:/home/irrgeist# uname -a
Linux debian 3.16.0-4-amd64 #1 SMP Debian 3.16.39-1 (2016-12-30) x86_64 GNU/Linux

I rebooted the system.

According to the official website the Intel® Dual Band Wireless-AC 8260 work on kernel version 4.1 and higher.

You can add the backports repo to your sources.list 

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

Update and run apt-cache search linux-image to get the available linux-image then install a kernel > 4.1

e,g :

apt-get install linux-image-4.8.0-0.bpo.2-amd64

or the latest kernel version: 

apt-get install linux-image-4.9.0-0.bpo.1-amd64-unsigned

Reboot your system and install the firmware-iwlwifi needed to get the Bluetooth working :

apt-get install -t jessie-backports firmware-iwlwifi

The wifi firmware iwlwifi-8000C-16.ucode is included on the firmware-iwlwifi package , also it can be added through :

wget https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-8000-ucode-16.242414.0.tgz
tar xvf iwlwifi-8000-ucode-16.242414.0.tgz
cd iwlwifi-8000-ucode-16.242414.0
cp iwlwifi* /lib/firmware

EDIT

To solve the black screen after installing the new kernel reinstall xserver-xorg-video-intel from backports , to get more info about the problem , see the answer of Stephen Kitt.

apt-get remove xserver-xorg-video-intel 
apt-get install -t jessie-backports xserver-xorg-video-intel

  • Just did this with ´apt-get install -t jessie-backports linux-image-amd64´ and rebooted...now I get a black screen while booting (it's loading the new Kernel) ... first time I do this kind of task x_X ... switching to TTY works, startx says, it could not find a monitor x_X Guess I have to remove it and do it your way... – DoubleVoid Feb 06 '17 at 19:59
  • Boot the `3.16` kernel from the advanced option of debian on GRUB menu then install the new kernel using : `apt-get install linux-image-4.9.0-0.bpo.1-amd64-unsigned ` – GAD3R Feb 06 '17 at 20:03
  • Did it, same problem though :( – DoubleVoid Feb 06 '17 at 20:08

    run `apt-get remove xserver-xorg-video-intel && apt-get install -t jessie-backports xserver-xorg-video-intel` More info [here](http://unix.stackexchange.com/a/307211/153195) – GAD3R Feb 06 '17 at 20:14
  • just did it, seems to work now :D But didn't remove the old one. Anyway, still no wlan0 available. Did modprobe again and rebooted, nothing. – DoubleVoid Feb 06 '17 at 20:21
  • Reload the driver `modprobe -r iwlwifi ; modprobe iwlwifi` – GAD3R Feb 06 '17 at 20:22
  • Does not work. I added the files in /lib/firmware to the first post ... maybe it's taking the wrong one?! – DoubleVoid Feb 06 '17 at 20:24
  • Does the `wireless-tools` is installed on your system? – GAD3R Feb 06 '17 at 20:25
  • yes they are, using iwconfig to check for the interface. ifconfig does list eth0 and lo. same for iwconfig – DoubleVoid Feb 06 '17 at 20:26
  • I will edit may answer , please add `non-free` to the backports source – GAD3R Feb 06 '17 at 20:28
  • I already did, posted my sources.list in the first post. :/ – DoubleVoid Feb 06 '17 at 20:32

    Ah now it works, just saw your edit about installing the firmware from the backports...wow! Thank you very much!! :D – DoubleVoid Feb 06 '17 at 20:34

according to intel-supports-site

you need higher kernel-version (4.1). Try kernel from backports.

I went to the synaptic package manager and typed in iwlwifi, then hit search. this gave me the option of firmware-iwlwifi, which I selected and installed. then I rebooted wifi now seen, I am connected right now.

Debian stretch 9, with the intel 8260 WLAN/Bluetooth card (I am new to Debian this month but have been using Ubuntu, Mint, Manjaro, since 2012).
