Realtek PCIe GBE NIC Driver

Applicable for RTL8111/8168/8411 PCIe GBE NIC.

Using the official driver will resolve sending rate being capped at 4MB/s per tcp connection under tcp-bbr, typically when you’re using the default r8169 nic driver on RTL8168 device. Newer distros like Ubuntu 18.04.3 with a mainline Linux 5.3 should not have the problem any more. You should try this driver only if you did notice the sending rate degradation.

apt update && apt install build-essential libelf-dev linux-headers-$(uname -r)

git clone https://github.com/airium/Realtek-PCIe-GBE-NIC-Driver.git cd Realtek-PCIe-GBE-NIC-Driver/r8168-8.047.05 sh autorun.sh # this script will break the network temporarily # on Ubuntu 16/18, your ssh session will be automatically resumed in ~1 minute # on Debian 8/9, you might have to reboot manually after ~5 minutes

for i in $(ls /sys/class/net); do echo $i '=====================' ethtool -i $i done

enp4s0 ===================== driver: r8168 version: 8.047.05-NAPI firmware-version: expansion-rom-version: bus-info: 0000:04:00.0 supports-statistics: yes supports-test: no supports-eeprom-access: no supports-register-dump: yes supports-priv-flags: no

Compared with the reference, this guide complements necessary dependencies, and removes the blacklist operation (it seems the Realtek driver will do it for you).

README.md

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.

Dependencies for manual installation on Arch Linux

sudo pacman -Syu linux-headers dkms bc

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

Manual installation of driver

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

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 removal script:

Make sure you have your local copy of this repository fully updated:

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:

This will enable verbose debug logging, helpful to developers.

PCIe Active 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 pcie_aspm=off at the end of GRUB_CMDLINE_LINUX_DEFAULT. Line should look like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=off"

Then update your GRUB configuration:

On systems that doesn’t have update-grub but have grubby like Fedora, you can directly execute instead:

sudo grubby --update-kernel=ALL --args=pcie_aspm=off

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 #19 (comment) to see if that helps you out.

If your system uses Secure Boot, the kernel will not accept user-supplied modules. There are two ways to solve this issue:

Disable Secure Boot via BIOS/UEFI settings.
Create or use an existing MOK (Machine Owner Key) to sign the compiled .ko linux kernel object produced by DKMS.

Unstable connection — slowdowns or dropouts

The problem may be due to the periodic scanning of access points by the network applet.

This fix worked helpful on Pop! _OS/Ubuntu 20.10 and Fedora 33. Both with GNOME and NetworkManager. #179

Set the BSSID from your network applet. In GNOME this can be done in WiFi Settings > Your profile > Identity > BSSID .

We are going to disable the Connectivity Check option in NetworkManager. This by editing the file in /var/lib/NetworkManager/NetworkManager-intern.conf and adding the following instructions at the end:

[connectivity] .set.enabled=false

Then, just reboot or restart the NetworkManager unit to fix the problem.

Wi-Fi not working for kernel >= 5.9

The Linux Kernel 5.9 version comes with a broken rtw88 module developed by Realtek that has poor compatibility with most revisions of the 8821ce chip.

You must disable it by adding the following to your module blacklists ( /etc/modprobe.d/blacklist.conf ):

Then, make sure you have the rtl8821ce module correctly installed.

Turn off your computer, wait a few seconds (to force firmware reload) and then turn it on again.

Wi-Fi and Bluetooth don’t work after suspend

This is a bug that won’t be fixed until/if Realtek implements proper power management themselves. Given they are now only working in rtw88 , this driver will most likely never be fixed in this regard. Please avoid opening issues about this.

Monitor (promiscuous) mode doesn’t work

This driver doesn’t support it and never will. Please avoid opening issues about this.
