@jackoneill I’ve been running with those options in modprobe.d using the built-in kernel module for a few days now and my system hasn’t crashed so far. I’ll report back if it does

jackoneill commented on 2021-07-11 10:58

@senorsnor: Those patches do the same thing as putting „options rtw_pci disable_aspm=1” in a file in /etc/modprobe.d/, but only for those specific machines. („rtw88_pci” for the built-in module, and „rtw_pci” for lwfinger’s version.)

Have you tried that option? I tried it and it didn’t help. My laptop is HP 250 G7.

senorsnor commented on 2021-07-11 10:35

Recently some patches were done describing the exact same symptoms some of us face:

Both «disable pci capabilities» based on hardware model: Protempo Ltd L116HTN6SPW and HP Pavilion Laptop 14-ce0xxx respectively. I’m not familiar with C or kernel/driver development so I don’t know exactly what this is about, but this solution worries me:

My laptop, which shows the exact same symptoms, is an HP Pavilion Laptop 15-cs0xxx (note the 15-cs, rather than the 14-ce as in the patch).

Before I reply with this to the mailing list, I thought I make an inventory here with the people that run into the same issue. Which hardware are you using?

You can find the info with the command sudo dmidecode | grep -A3 ‘^System Information’

senorsnor commented on 2021-05-28 08:38

For me the screen doesn’t update either, mouse movements and key presses are not processed anymore. System is completely frozen. Not sure about the fan speed during a system freeze.

When using the kernel drivers, my system feels unstable. Fan speed goes up and down at seemingly random moments. When I tested with rtw88-dkms-git that seemed to have disappeared, unfortunately my system still freezes.

jackoneill commented on 2021-05-27 12:21

@CodingEagle02: It doesn’t look like that here. The screen looks normal, it just doesn’t update anymore. The mouse cursor doesn’t move. Ctrl+Alt+F1..6 have no effect. The fan may speed up a little after a while. It doesn’t go full speed. I didn’t try the Sysrq stuff.

CodingEagle02 commented on 2021-05-26 21:50

What kinds of freezes are you all getting? I’ve noticed I get a really weird and specific, where my screen suddenly goes black, and my fan starts going at full speed. The kill X server command doesn’t work, but REISUB mostly does. I never used to get these. I’m too lazy to post the logs somewhere at the moment, but if people are dealing with the same thing, then I guess it’s just a matter of waiting until Linus and Realtek get their shit together.

senorsnor commented on 2021-05-21 09:20

@jackoneill ok too soon .. system just froze twice with rtw_8821ce

senorsnor commented on 2021-05-21 08:50

@jackoneill Thanks for that, then indeed I tested with the current kernel driver. Now testing rtw88-dkms-git for a few hours and so far it works great. If the system crashes then i’ll report here.

jackoneill commented on 2021-05-20 21:19

The driver that comes with the kernel is called rtw88_8821ce (and rtw88_<8821c,pci,core>). The driver in the rtw88-dkms-git package is called rtw_8821ce (and rtw_<8821c,pci,core>). The driver from the kernel seems to have higher priority. So the file in /etc/modprobe.d/ needs to contain these lines:

blacklist rtw88_8821ce blacklist 8821ce

senorsnor commented on 2021-05-20 19:54

@jackoneill I just installed rtl88-dkms-git, removed rtl8821ce-dkms-git, unblacklisted the rtw88-driver. Rebooted, system froze within an hour. I didn’t know how to verify that the driver from the package is used, and not the driver supplied with the kernel? Oh, and the system seemed to use excessive cpu as well, but not sure.

Rtl8821ce linux driver manjaro

Realtek RTL8821CE Driver

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.

Installation of Driver

Make sure you have a proper build environment and dkms installed.

The following steps are required prior to building the driver on Ubuntu/Debian:

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.

Installing from AUR

Dependencies for manual installation on Arch Linux

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.

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:

Removal of Driver

Open a terminal window and git clone the repository to your local disk

Then run the installation script:

Remove the driver:

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

Clean any stale binaries:

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 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:

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

Then update your GRUB configuration:

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:

BlueTooth is not working

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 https://github.com/tomaspinho/rtl8821ce/issues/19#issuecomment-452196840 to see if that helps you out.

If your system uses Secure Boot, disable it via BIOS settings, otherwise the kernel will not accept user-supplied modules.

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:

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 revision 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.

Установка драйвера wi fi rtl8821 CE

Коротко говоря установил Manjaro KDE 5.4. При установке, собственно сам установщик ругнулся насчет того что не все компоненты ОС буду работать корректно после установки. Я рискнул и установил и как итог у меня не определяются точки Wi Fi (вообще не ловит сеть). Покопался в диспетчере оборудования и понял, что не установлен драйвер от Realtek — rtl8821 ce 802.11 и т.д.

Прошу помочь в установке данного драйвера, так как я полный профан в линуксе и практически не разбираюсь в консоле (только знакомлюсь с кодами)

Ниже прилагаю информацию которая должна помочь продвинутым.
Заранее спасибо.

Проблемы с WIFI адаптерами RTL8821CE в Linux

Добрый день всем, кто оказался на данном сайте. В последнее время можно сталкнуться с тем, что нет драйвера на WIFI адаптер RTL8821CE. К примеру, я сталкнулся с этой проблемой когда приобрел новый ноутбук. Хотя например в Ubuntu 19.10 этот драйвер есть в репозиториях. Но, например в Debian и MX Linux его нет. Решается это довольно просто. Установкой его с gihub. И так, приступ. Для начала установим git:

Теперь можно приступать к скачиванию исходного пакета с gihub:

После чего переходим в папку с нашим исходником и приступаем к установке. Для начала скомпилируем исходник командой “make” и потом установим при помощи команды “install”

После успешной установки, нужно перезагрузить систему. После чего WIFI устройство обнаружиться системой и будет работать. А на этом сегоня все. Надеюсь данная статья будет вам полезна.

не сработало, у меня elementary os

введи команду inxi -F и скинь мне на мыло скрин, или на форуме можно посмотреть решение проблемы может кто и сталкивался http://linuxhome.spiritfamily.ru/forums/

У меня elementary os и всё сработало ноутбук HP 255 G7

HP, Elementary – нет wifi, Linux Mint – тоже нет. Просмотрел, перечитал кучу информации -ничего. Случайно наткнулся на ваш сайт – 10 минут и проблема решена. Благодарю Вас за краткость и доступность.

Спасибо, все понятно.

Сработало на Ubuntu 20.04.1! Спасибо!

как скачать, если нет интернета?

Можно подключиться по витой паре – по проводу, скачать и установить. А вообще, щас в ядро Linux уже добавили данный драйвер, его только в настройках активировать и все работает

Я подключил телефон через USB кабель.

автор, спасибо. супер статья и , главное, что без ошибок. множество статей на эту тему в сети, но ,видимо, авторы не сильно понимали, о чем пишут.. поэтому в статьях ошибки. у тебя все в порядке. спасибо. помогло решить задачу и не скатиться к использованию винды )))

Блаеодарю! думал уже на другую OS переходить
Все сработало на отлично, я снова с WIFI
ядро 5.10.6-desktop-1.mga7
ноут ASUS 2019 г.
карточка RTL8821ce
OS Mageia 7

Спасибо автору. Всё чётко и разумно. Для первичного подключения к сети использовал телефон через USB кабель.

Супер! Все получилось. Спасибо огромное.

Чуть было не забыл! Первым шагом отключаем Secure Boot в Биосе!
