networking - Wifi connections not showing up on ubuntu 16.04

I have a fresh install of ubuntu 16.04 in a thinkpad e470 but no wifi appears nor the option to enable the wifi. I already tried enabling it using the fn key, but it still doesn't work.

I already tried many different approaches, including trying to update the packages, checking for drivers, restarting network manager and following these solutions:

Wifi networks are not showing in Ubuntu 16.04

Unfortunately none of this worked :/

The output from lshw -C network is as follow:

Any help is appreciated! :)
Thank you very much!

So I finally managed to make it work. What was missing was the driver 8821ce.

I followed the answer found here:
