I just got a Samsung NP900 and I erased everything and installed Linux Mint 18.1. While installing, I chose the option to install third-party software (and nothing else; meaning I didn't mess with the secure boot settings and stuff like that).

The installation went smoothly, but when I boot everything I can't get the wifi to get recognized. The output of rfkill list only lists the Bluetooth, but nothing else. (By the way, I don't have access to any cable internet, so I can't really test the cable connection on it).

Here's the output of inxi -N:

Network:    Card: Intel Device 24fd

Any ideas?

EDIT

I'm running x86_64.

The output of lspci -nn gives me this version for the Networks controller:

Network controller [0280]: Intel Corporation Device [8086:24fd] (rev 78)

Please post output of inxi -N – Luka Apr 22 '17 at 18:51
    
@Luka Just edited in the question. Only one card is showing and no driver. Could this be used to my advantage? askubuntu.com/a/859263 – TomCho Apr 22 '17 at 18:57
    
Try finding your wireless card with lspci -nn We need model and manufacturer of WiFi card so i can give you driver to install. Also you didn't wrote is your Linux Mint arch or not. Type arch and if output is x86_64 that means you are 64bit. You can also try connecting to LAN and doing sudo apt-get upgrade && apt-get update that my find correct missing drivers. – Luka Apr 22 '17 at 19:02
    
@Luka just added to the question. I have to type by hand with my other computer, because I can't access the internet with the new one. I was wondering if just upgrading my kernel would work (and if it's easier). – TomCho Apr 22 '17 at 19:08
    
This issue is about internal WiFi card not external. – Luka Apr 22 '17 at 19:14

This is a fix for you, but you need to connect your laptop to internet by using LAN cable.

sudo apt-get install build-essential linux-headers-generic
wget https://www.kernel.org/pub/linux/kernel/projects/backports/2015/12/18/backports-20151218.tar.gz
tar -zvxf backports-20151218.tar.gz
cd backports-20151218
make defconfig-iwlwifi
make
sudo make install

EDIT: Since you do not have Ethernet....

Download https://www.kernel.org/pub/linux/kernel/projects/backports/2015/12/18/backports-20151218.tar.gz and place file to your usb flash drive, then place it from flash drive on your Linux Mint Desktop... Execute:

cd ~/Desktop
tar -zvxf backports-20151218.tar.gz
cd backports-20151218
make defconfig-iwlwifi
make
sudo make install

Reboot and post output of

dmesg | grep iwl

If it works, a kernel update will break wireless and you will need to repeat process (after tar command)

I just realized I don't have an ethernet port, so I'll buy an adaptor, try to find cable internet and port the results. This means that upgrading to a newer kernel won't fix the problem, right? – TomCho Apr 22 '17 at 19:21
    
I do not it might fix it, but what I found out is that driver is not available in mint for your card. You do not have ethernet? Well you must have flash drive. I'll edit my answer in a minute, let me know when you try it. – Luka Apr 22 '17 at 19:24
    
I've run into a larger problem, detailed here (if you're interested). After I solve that I'll try your solution. – TomCho Apr 22 '17 at 23:18
    
Thanks for the help, but I wasn't able to complete your command because there were some package dependencies. I was able to make everything work by upgrading to Linux 4.9 kernel, though. – TomCho Apr 23 '17 at 1:41

According to the official website the Intel® Dual Band Wireless-AC 8265 will work on the 4.6 kernel version and higher

1) Upgrade your kernel version : the 4.8 and the 4.10 kernel is available for linux mint.

2) Install the wifi driver

wget https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-8265-ucode-22.361476.0.tgz
tar xvf iwlwifi-8265-ucode-22.361476.0.tgz
cd iwlwifi-8265-ucode-22.361476.0
cp iwlwifi* /lib/firmware
modprobe iwlwifi

What solved the problem was upgrading the Kernel to version 4.9. Basically all I did was download the headers and image here, pass them on to the new laptop via flashdrive and install them with dpkg -i *deb. A couple of error messages like this one but I think they weren't important, since everything is working fine.

After the new Kernel was installed, I installed the newer 4.10 kernel through the update manager, so that it can have a proper update-receiving installation.

It is better to install the new kernel through apt , a custom kernel doesn't receive a security update , Installing the 4.6 or 4.10 kernel from the regulary linux-mint repo will solve your problem – GAD3R Apr 23 '17 at 11:29
    
I didn't know that custom kernels didn't receive security updates. But I was planning on updating the kernel through apt anyway, now that I can access the internet. I'll include that in the answer. – TomCho Apr 23 '17 at 17:11
