Wi-Fi not working on Lenovo ThinkPad E570 (Realtek RTL8821CE)
We just bought a Lenovo ThinkPad E570 (which is supposed to have the Intel 8265 for wireless). This laptop was bought in part because it is certified to run Ubuntu and as such to me at least it would make sense for things to work out of the box... but no such luck.
First, I installed Ubuntu 17.10 and after installation realised Wi-Fi was not working. I also tried Ubuntu 16.04 from a USB drive since that is the version of Ubuntu it is certified for, but no luck there either.
The wireless chip is not detected by lshw
(or even lspci
by the looks of it), ip link
does not show a wireless interface, and the iwlwifi
kernel module is not loaded at boot (I can load this myself using modprobe iwlwifi
but this does not make Wi-Fi work). I think it is a combined Wi-Fi/Bluetooth chip, and Bluetooth does appear to work (or at least Bluetooth shows up in Gnome and rfkill list
).
modinfo iwlwifi | grep 8265
shows me a file ending in -34 is supposedly loaded but only a file ending in -33 (and some other lower numbers) is present in /lib/firmware
, if that helps).
I have also installed the Linux 4.14.9 kernel in an attempt to get things to work, but this did not resolve the issue either.

I just noticed that the laptop does not have an Intel wireless chip at all, but in fact has a Realtek one... which means that the specs presented on the product page of the shop I bought this laptop at were not accurate... Sigh. Same problem stands, however, just with a crappier wireless chip.

First, I would suggest that these instructions are more likely to work with Ubuntu 17.10. If you are not currently running it now, I suggest that you re-install it.
Click this link to download the driver file: https://minhaskamal.github.io/DownGit/#/home?url=https://github.com/endlessm/linux/tree/master/drivers/net/wireless/rtl8821ce
Unless you have specified otherwise in your browser, downloads go to the directory Downloads. Open a terminal and do:
cd ~/Downloads
unzip rtl8821ce.zip
cd rtl8821ce
nano Makefile
Scroll down to line 152 and change the line that now reads:
export TopDIR ?= $(srctree)/drivers/net/wireless/rtl8821ce
To now read:
export TopDIR ?= $ ~/Downloads/rtl8821ce
Proofread carefully, twice, and save (Ctrl+o followed by Enter) and close (Ctrl+x) the text editor.
Now do:
make
sudo make install
sudo modprobe 8821ce
Your wireless should now be working.
EDIT: You have compiled the module for your currently running kernel version only. When Update Manager offers a later kernel version, known as linux-image, after the requested reboot, you must recompile:
cd rtl8821ce
make clean
make
sudo make install
sudo modprobe 8821ce
Please retain the file and these instructions for that time.
This is what I found yesterday as well and it worked :) One thing I'm curious about is whether this will keep working across kernel updates, though.

This is a follow up to stason's answer who suggests using dkms.
As far as I can tell, at the time of writing this, there is not yet a Wifi Driver for the Realtek RTL8821CE in the official Ubuntu Repositories.
Over on github there is a repository with an RTL8821CE driver aimed at kernels 4.14 and above and specifically for Arch Linux with no support provided for other Linux Distros: https://github.com/tomaspinho/rtl8821ce
It has, however, been reported to work just fine with Ubuntu 18.04.
A temporary internet connection will be required (such as an ethernet cable, USB wifi dongle or connecting your phone with a usb cable and 'tethering' it to use your phone's Wifi)
The solution is taken directly from post #4 by Praseodym (much praise to their wisdom!): https://ubuntuforums.org/showthread.php?t=2398917 and will install a number of packages for building the wifi driver module (git, dkms, build-essential & linux-headers) and clone the rtl8821ce git repository from tomaspinho (much praise also!).
DKMS is used because it's "a system which will automatically recompile and install a kernel module when a new kernel gets installed or updated."
Open up a terminal and type the following lines (You can cut and paste if you prefer):
sudo apt-get install --reinstall git dkms build-essential linux-headers-$(uname -r)
git clone https://github.com/tomaspinho/rtl8821ce
cd rtl8821ce
chmod +x dkms-install.sh
chmod +x dkms-remove.sh
sudo ./dkms-install.sh
After this is completed successfully, you should reboot and find that your Wifi is working.
You also want to make sure SecureBoot is Disabled in the BIOS settings or it won't let you load the unsigned self-complied kernel module.
I can confirm the you don't need to disable SecureBoot. If you have SecureBoot enabled simply follow the prompts during thesudo ./dkms-install.sh
and enter the same password which you will choose during the reboot.

Update 2018-02-27
Please note the suggested driver is for Endless OS and therefore it might break at any point. If any body has an official driver for Ubuntu it will be better.
Original Answer
This is not a new answer, would be better a comment.
So I tried to follow @chili555 answer but I kept getting errors while trying to make the module.
Errors like:
/rtl8821ce/include/osdep_service_linux.h:294:2: error: implicit declaration of function ‘timer_setup’; did you mean ‘ether_setup’?
[-Werror=implicit-function-declaration]
timer_setup(ptimer, pfunc, 0);
^~~~~~~~~~~ ether_setup
So I tried downloading a different revision (zip archive direct download link) which by the time of the original answer might be master as well. Then I was able to make the module and install following the steps provided by @chili555
add a comment |
A solution for the timer error.
I manage to make it work for my lenovo E570 with ubuntu 16.04 and here are my steps:
First, I upgrade my kernel version to 4.15.4 using this guide
I believe any kernel version above 4.15.4 should work because I had to upgrade my kernel to 4.15.9 again. Note the driver needs to be reinstalled.
Then, I followed the steps mentioned in @chili555 answers
What do you mean by "installing the driver"?
– pim
Mar 13 '18 at 5:44
It means you need to sudo make install again. please let me know if it worked for you and what kernel version are you using. This method worked for me before, but recently I had to reinstall ubuntu several times and it stopped working for me.
– Juichung_Kuo
Mar 13 '18 at 21:58
The following thread includes an alternative driver to the 8821ce, link and it works for me again

dkms build/install for rtl8821ce can be found here: https://github.com/tomaspinho/rtl8821ce
When you use that approach you won't need to rebuild the module each time kernel is updated.
I have just built it on Lenovo Idea 720s with kubuntu 18.04.
Also I suggest you edit Makefile to change the log level from 4 (info) to 3 (warnings). Otherwise you will find your /var/log/syslog
filling up at a crazy speed with useless info messages from the driver.
So edit Makefile, to change:
CONFIG_RTW_LOG_LEVEL = 4
to:
CONFIG_RTW_LOG_LEVEL = 3
and then build and install the module as per instructions. If you already installed it, you need to uninstall it (using dkms-remove.sh
) and then reinstall it again.
Alternatively you can manually change the log level until next reboot with:
echo 3 > /proc/net/rtl8821ce/log_level
update: the maintainer changed the Makefile to reflect this suggestion, so if you make a fresh checkout/download it'll already have the right (quiet) setting.

For me edit the file wasnt necessary. Just download driver compile install and activate mod where enough. Thanks!!!

This is a follow up to stason's answer who suggests using dkms.
As far as I can tell, at the time of writing this, there is not yet a Wifi Driver for the Realtek RTL8821CE in the official Ubuntu Repositories.
Over on github there is a repository with an RTL8821CE driver aimed at kernels 4.14 and above and specifically for Arch Linux with no support provided for other Linux Distros: https://github.com/tomaspinho/rtl8821ce
It has, however, been reported to work just fine with Ubuntu 18.04.
A temporary internet connection will be required (such as an ethernet cable, USB wifi dongle or connecting your phone with a usb cable and 'tethering' it to use your phone's Wifi)
The solution is taken directly from post #4 by Praseodym (much praise to their wisdom!): https://ubuntuforums.org/showthread.php?t=2398917 and will install a number of packages for building the wifi driver module (git, dkms, build-essential & linux-headers) and clone the rtl8821ce git repository from tomaspinho (much praise also!).
DKMS is used because it's "a system which will automatically recompile and install a kernel module when a new kernel gets installed or updated."
Open up a terminal and type the following lines (You can cut and paste if you prefer):
sudo apt-get install --reinstall git dkms build-essential linux-headers-$(uname -r)
git clone https://github.com/tomaspinho/rtl8821ce
cd rtl8821ce
chmod +x dkms-install.sh
chmod +x dkms-remove.sh
sudo ./dkms-install.sh
After this is completed successfully, you should reboot and find that your Wifi is working.
You also want to make sure SecureBoot is Disabled in the BIOS settings or it won't let you load the unsigned self-complied kernel module.
I can confirm the you don't need to disable SecureBoot. If you have SecureBoot enabled simply follow the prompts during thesudo ./dkms-install.sh
and enter the same password which you will choose during the reboot.

Update 2018-02-27
Please note the suggested driver is for Endless OS and therefore it might break at any point. If any body has an official driver for Ubuntu it will be better.
Original Answer
This is not a new answer, would be better a comment.
So I tried to follow @chili555 answer but I kept getting errors while trying to make the module.
Errors like:
/rtl8821ce/include/osdep_service_linux.h:294:2: error: implicit declaration of function ‘timer_setup’; did you mean ‘ether_setup’?
[-Werror=implicit-function-declaration]
timer_setup(ptimer, pfunc, 0);
^~~~~~~~~~~ ether_setup
So I tried downloading a different revision (zip archive direct download link) which by the time of the original answer might be master as well. Then I was able to make the module and install following the steps provided by @chili555

A solution for the timer error.
I manage to make it work for my lenovo E570 with ubuntu 16.04 and here are my steps:
First, I upgrade my kernel version to 4.15.4 using this guide
I believe any kernel version above 4.15.4 should work because I had to upgrade my kernel to 4.15.9 again. Note the driver needs to be reinstalled.
Then, I followed the steps mentioned in @chili555 answers
What do you mean by "installing the driver"?
– pim
Mar 13 '18 at 5:44
It means you need to sudo make install again. please let me know if it worked for you and what kernel version are you using. This method worked for me before, but recently I had to reinstall ubuntu several times and it stopped working for me.

dkms build/install for rtl8821ce can be found here: https://github.com/tomaspinho/rtl8821ce
When you use that approach you won't need to rebuild the module each time kernel is updated.
I have just built it on Lenovo Idea 720s with kubuntu 18.04.
Also I suggest you edit Makefile to change the log level from 4 (info) to 3 (warnings). Otherwise you will find your /var/log/syslog
filling up at a crazy speed with useless info messages from the driver.
So edit Makefile, to change:
CONFIG_RTW_LOG_LEVEL = 4
to:
CONFIG_RTW_LOG_LEVEL = 3
and then build and install the module as per instructions. If you already installed it, you need to uninstall it (using dkms-remove.sh
) and then reinstall it again.
Alternatively you can manually change the log level until next reboot with:
echo 3 > /proc/net/rtl8821ce/log_level
update: the maintainer changed the Makefile to reflect this suggestion, so if you make a fresh checkout/download it'll already have the right (quiet) setting.
