I just bought an Intel NUC6i3SYH and I installed Debian Jessie on it. I couldn't get the WiFi working. I already tried installing firmware-iwlwifi by following this tutorial, but it still doesn't work. I also tried installing with the Debian non-free installer, but it also doesn't work. It also doesn't work with Lubuntu, but it works with Linux Mint. How can I get it working with Debian?

  • What have you tried? What did you expect to happen? What happened instead? What do the logs say?

  • @JennyD I tried doing this, but after that my WiFi still doesn't work. If you need the output of a command, tell me…

According to wireles-wiki-kernel Intel® Wireless 8260 is supported by Kernel version > 4.1. To get wifi working you need to install the required firmware from backport (the easy way) or Upgrade your current kernel version.

First you need to enable backport

 echo deb http://ftp.debian.org/debian jessie-backports main contrib non-free | sudo tee /etc/apt/sources.list.d/jessie-backports.list

Then install the required firmware through the following command:

 sudo apt-get update  && sudo apt-get install -t jessie-backports  firmware-iwlwifi

  • +GAD3R I tried that and it doesn't work, so what packages do I need to apt-get download to update the kernel?

The Intel NUC6i3SYH has an Intel Wireless-AC 8260 M.2 wireless antenna, requiring the iwlwifi-8000-ucode firmware, which does not automatically ship with Debian Jessie. You may simply download the firmware from the second site, unpack it with

tar xvf iwlwifi-8000-ucode-25.30.13.0.tgz

and place one of the files thusly obtained, iwlwifi-8000-ucode-25.30.13.0/iwlwifi-8000C-13.ucode, in the directory /lib/firmware, reboot, and you should be good to go.

  • Have you checked you have the exact version of the firmware above, i.e. 8000C-13? That's not mentioned anywhere in your post. Aug 1, 2016 at 16:16
