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.

edit 11/9/18 4:10pm:

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.

  • Please edit your question to show the result of the terminal command: uname -r Welcome to Ask Ubuntu, – chili555 Nov 9 '18 at 20:20
  • The device is supported in kernel version 4.15. Let's see what happens when you load it and check the log: sudo modprobe iwlwifi && dmeg | grep iwl – chili555 Nov 10 '18 at 1:13

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.
