16.04.5 - Wifi not working Matebook X Pro

I've been having problems getting wi-fi to work on my Huawei Matebook X Pro with Ubuntu 16.04.5 . The problem seems to be similar to the one found here, Wifi not working (Intel) on HP Spectre x360 13, but one of the links to a firmware download is dead. Also, that answer is for 14.04 - is it suitable for 16.04?

iwconfig output:

lo no wireless extensions.
bnep0 no wireless extensions.

relevant lspci -v output:

`sudo lshw -c Network -sanitize' output:

Thank you.

uname -r output:

4.15.0-38-generic

BUT also, someone helped me troubleshoot IRL, we did a kernel update, and the wifi now works, so I guess this problem can be closed.

My solution for the Huawei Matebook X Pro, linux-kernel version 4.16, is the following:

1. Determine the name of your Wifi-Device (mine was Intel® Dual Band Wireless-AC 8265)
2. Download the appropriate Firmware files (similar numbers also work) from the Intel Website
3. Unpack the .ucode file and put it in the folder /lib/firmware
4. Reboot your system

It should work immediately after the last step.
