I am new to Linux *using Ubuntu 14.04) and am having issues getting my wi-fi drivers to install. I found the appropriate files online and pasted them into the /lib/firmware directory as the install notes say. However, I am at a loss of words on how to load those drivers in the kernel. I've Googled and not come up with much at all. This is what the install notes say:

The iwlwifi driver will look for the file iwlwifi-8000C-13.ucode using the kernel's firmware_class infrastructure. More information can be found under Documentation/firmware_class in kernel source. In order to function correctly, you need to have this support enabled in your kernel. When you configure the kernel, you can find this option in the following location:

Device Drivers -> Generic Driver Options -> Userspace firmware loading support

You can determine if your kernel currently has firmware loader support by looking for the CONFIG_FW_LOADER definition on your kernel's .config.

In addition to having the firmware_class support in your kernel, you must also have a working udev and uevent infrastructure configured. The steps for installing and configuring udev are very distribution specific.

Once you have the firmware loader in place (or if you aren't sure and you just want to try things to see if it works), you need to install the microcode file into the appropriate location.

Where that appropriate location is depends (again) on your system distribution. You can typically find this location by looking in the udev scripts of your distro, the default is /lib/firmware."

How do I do this?

Thanks for your help!

Edit: I used this in hte terminal

 lspci -knn | grep Net -A2; uname -a

And I got the following information: 

Network controller [0280]: Intel Corporation Wireless 8260 [8086:24f3] (rev 3a)
    Subsystem: Intel Corporation Device [8086:1130]
05:00.0 PCI bridge [0604]: Intel Corporation Device [8086:1576]

From uname -a

Your kernel is not supported any more and does not support the wireless adapter. You need to upgrade it. Run in terminal

sudo apt-get install linux-generic-lts-xenial

and reboot.

The wireless adapter should work if you updated the system and have the latest linux-firmware package.

I figured out the answer by looking elsewhere on this site. I found the answer here: Intel wireless 8260 - unclaimed network

I went to https://www.kernel.org/pub/linux/kernel/projects/backports/2016/03/24/backports-20160324.tar.gz

Extracted it, navigated to the directory in the terminal and performed the following commands, as outlined in the link I posted above.

cd ~/Desktop/backports-2016324
make clean
make defconfig-iwlwifi
make
sudo make install

I rebooted and everything worked like a charm.
