Realtek RTL8821CE Driver

Intent

This repository hosts the code for the ArchLinux AUR Package. It's targetting Linux > 4.14 and is being developed for ArchLinux and Ubuntu 18.10. No support will be provided for other Linux distributions or Linux Kernel versions outside of that range.

DKMS

This driver can be installed using DKMS. This is a system which will automatically recompile and install a kernel module when a new kernel gets installed or updated. To make use of DKMS, install the dkms package.

Installation of Driver

In order to install the driver open a terminal in the directory with the source code and execute the following command:

sudo ./dkms-install.sh

Removal of Driver

In order to remove the driver from your system open a terminal in the directory with the source code and execute the following command:

Possible issues

PCIe Activate State Power Management

Your distribution may come with PCIe Active State Power Management enabled by default. That may conflict with this driver. To disable:

sudo $EDITOR /etc/default/grub

Add pci=noaer at the end of GRUB_CMDLINE_LINUX_DEFAULT. Line should look like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"

Then update your GRUB configuration:

sudo update-grub

Reboot.

Lenovo Yoga laptops

Some new Yoga laptops (like the Yoga 530) come with rtl8821ce as the Wi-Fi/Bluetooth chip. But the ideapad-laptop module, which may come included in your distribution, may conflict with this driver. To disable:

sudo modprobe -r ideapad_laptop
