This repository hosts the code for the Arch Linux AUR Package. It's targeting Linux > 4.14 and is being developed for Arch Linux and Ubuntu 18.10. No support will be provided for other Linux distributions or Linux Kernel versions outside of that range.
The maintainers of this repository are not Realtek employees and are maintaining this repository for their own usage. Further feature development (such as proper power saving, etc.) will not be pursued here, but will be gladly integrated if newer driver sources are provided by Realtek. Use at your own risk.
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.
Make sure you have a proper build environment and dkms
installed.
The following steps are required prior to building the driver on Ubuntu/Debian:
sudo apt install bc module-assistant build-essential dkms
sudo m-a prepare
Ubuntu users may also install the prebuilt rtl8821ce-dkms package, an older version of the driver maintained by the Ubuntu MOTU Developers group for bionic, eoan and focal. It has been known to work in cases where the newer driver available here does not. Bugs and issues with that package should be reported at Launchpad rather than here.
Make sure you have the base-devel
package group installed before you proceed for the necessary compilation tools.
Install rtl8821ce-dkms-git from the AUR.
sudo pacman -Syu linux-headers dkms
If you are running a non-vanilla kernel then install the headers to match the kernel package. Proceed to the section below.
An unofficial Gentoo package is available, using this repository as upstream. It is available from the trolltoo overlay. Gentoo does not use or require dkms for packaged drivers.
# layman -a trolltoo
# emerge --ask net-wireless/rtl8821ce-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
Open a terminal window and git clone the repository to your local disk
git clone https://github.com/tomaspinho/rtl8821ce.git
cd rtl8821ce
Then run the installation script:
sudo ./dkms-remove.sh
Remove the driver:
sudo ./dkms-remove.sh
Make sure you have your local copy of this repository fully updated:
git pull
Clean any stale binaries:
make clean
Install again:
sudo ./dkms-install.sh
When reporting issues, please make sure that debugging is enabled. To enable debugging either set MAKEFLAGS="CONFIG_RTW_DEBUG = y"
before compilation or edit Makefile:
CONFIG_RTW_DEBUG = y
This will enable verbose debug logging, helpful to developers.
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.
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
This may be due to the Kernel loading up the wrong firmware file for this card. Please take a look at @wahsot's tutorial at tomaspinho#19 (comment) to see if that helps you out.
