Look at dmesg command output, it will tell you what is missing i guess... but according to this:

https://www.intel.com/content/www/us/en ... rking.html

Intel® Dual Band Wireless-AC 8260 4.1+ iwlwifi-8000-ucode-25.30.13.0.tgz

So iwlwifi-8000C-13.ucode is yours i guess.

It seems that firmware is missing in 'firmware-iwlwifi' package... whatever, if dmesg complan about that named one just copy it in /lib/firmware and reboot

Hmm I tried this just now, I was able to download the file from Intels site and extracted the content in /lib/firmware, Did a reboot but the wlan interface does not show up in ifconfig.

Hi! Sorry for some reason I did not add deb http://httpredir.debian.org/debian/ stretch main contrib non-free in /etc/apt/sources.list. Once I did that it worked as a charm! Thank you so much for the help! :D

I suspected as much, even when you said in your second post

This why we get a skeptical attitude here, and demand to see actual terminal output, instead of a vague "it didn't work!"

What output do you need? I just followed the guide and added the non-free repos.
