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

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.

Warning: Beware of «multi-state» USB WiFi adapters. Some USB WiFi adapters have proprietary Windows drivers onboard. When plugged in, they act like a flash drive or CDROM and on Windows will attempt to start installing the Windows driver. That won’t work on Linux or MAC or any other non-Windows OS so the adapter sits there in flash drive or CDROM mode. The problem is that the state of the adapter has to be changed for the adapter to show up as the device that you expect, in this case, a WiFi adapter. Most modern Linux distributions ship with a utility called «usb-modeswitch» that will handle this issue for you if it has the correct information for your adapter. It is a good utility but if you buy adapters that are «multi-state,» that is one more potential headache you may have to deal with when something goes wrong. Often you can indentify adapters that are «multi-state» as they are advertised as «free driver» or «free installation driver.» If you are looking to buy a USB WiFi adapter for use on Linux, MAC OS, *NIX or anything besides Windows, it is a good idea to seek out single-state adapters.

Note: Some adapter makers change the chipsets in their products while keeping the same model number so please check to confirm that the product you plan to buy has the chipset you are expecting.

The installation instructions are for the novice user. Experienced users are welcome to alter the installation to meet their needs.

Temporary internet access is required for installation. There are numerous ways to enable temporary internet access depending on your hardware and situation. One method is to use tethering from a phone.. Another method to enable temporary internet access is to keep a wifi adapter that uses an in-kernel driver in your toolkit.

You will need to use the terminal interface. The quick way to open a terminal: Ctrl+Alt+T (hold down on the Ctrl and Alt keys then press the T key)

DKMS is used for the installation. DKMS is a system utility which will automatically recompile and install this driver when a new kernel is installed. DKMS is provided by and maintained by Dell.

It is recommended that you do not delete the driver directory after installation as the directory contains information and scripts that you may need in the future.

There is no need to disable Secure Mode to install this driver. If Secure Mode is properly setup on your system, this installation will support it.

Step 1: Open a terminal (Ctrl+Alt+T)

Step 2: Update the system (select the option for the OS you are using)

Step 3: Install the required packages (select the option for the OS you are using)

Step 4: Create a directory to hold the downloaded driver

Step 5: Move to the newly created directory

Step 6: Download the driver

Step 7: Move to the newly created driver directory

Step 8: Warning: this step only applies if you are installing to Raspberry Pi hardware.

Run a preparation script

Step 9: Run the installation script (For automated builds, use NoPrompt as an option)

A file called 8821au.conf will be installed in /etc/modeprobe.d by default.

This file will be read and applied to the driver on each system boot.

To edit the driver options file, run the edit-options.sh script.

Documentation for Driver Options is included in the file 8821au.conf .

Removal of the Driver

Note: This script should be used in the following situations:

• the driver is no longer needed
• a fresh start with default settings is needed
• a new version of the driver needs to be installed
• a major operating system upgrade is going to be applied

Note: This script removes everything that has been installed, with the exception of the packages installed in Step 3 and the driver directory. The driver directory can and probably should be deleted in most cases after running the script.

Step 1: Open a terminal (Ctrl+Alt+T)

Step 2: Move to the driver directory

Step 3: Run the removal script

Recommended WiFi Router/ Access Point Settings

Note: These are general recommendations, some of which may not apply to your specific situation.

Security: Set WPA2-AES. Do not set WPA2 mixed mode or WPA or TKIP.

Channel width for 2.4G: Set 20 MHz fixed width. Do not use 40 MHz or 20/40 automatic.

Channels for 2.4G: Set channel 1 or 6 or 11 depending on the congestion at your location. Do not set automatic channel selection.

Mode for 2.4G: For best performance, set «N only» if you no longer use B or G capable devices.

Network names: Do not set the 2.4G Network and the 5G Network to the same name. Note: Unfortunately many routers come with both networks set to the same name.

Channels for 5G: Not all devices are capable of using DFS channels. It may be necessary to set a fixed channel in the range of 36 to 48 or 149 to 161 in order for all of your devices to work on 5g. (for US, other countries may vary)

Best location for the wifi router/ access point: Near center of apartment or house, at least a couple of feet away from walls, in an elevated location.

Check congestion: There are apps available for smart phones that allow you to check the congestion levels on wifi channels. The apps generally go by the name of WiFi Analyzer or something similar.

After making and saving changes, reboot the router.

Set regulatory domain to correct setting in OS

Check the current setting

If you get 00, that is the default and may not provide optimal performance.

Set it temporarily

Note: Substitute your country code if you are not in the United States.

Set it permanently

Recommendations regarding USB

Moving your USB WiFi adapter to a different USB port has been known to fix a variety of problems. Problems include WiFi going on and off as well as connections coming and going.

If connecting your USB WiFi adapter to a desktop computer, use the USB ports on the rear of the computer. Why? The ports on the rear are directly connected to the motherboard which will reduce problems with interference and disconnection that can happen with front ports that use cables.

If your USB WiFi adapter is USB 3 capable then plug it into a USB 3 port.

Avoid USB 3.1 Gen 2 ports if possible as almost all currently available adapters have been tested with USB 3.1 Gen 1 (aka USB 3) and not with USB 3.1 Gen 2.

If you use an extension cable and your adapter is USB 3 capable, the cable needs to be USB 3 capable.

Some USB WiFi adapters require considerable electrical current and push the capabilities of the power available via USB port. One example is devices that use the Realtek 8814au chipset. Using a powered multiport USB extension can be a good idea in cases like this.
