For some reason, the rtl8821ce WiFi hardware works poorly or not at all on most Linux distros. Apparently, the driver used in the Linux kernel for this hardware is outdated or for other reasons that I don't know about, it doesn't work properly. The solution to this problem is a driver developed by a friend from Portugal and placed on GitHub.
In this guide, we want to build and install this driver.
