Realtek 8822CE wireless driver issues

Hi. I’m trying to get the wireless card work on a Lenovo Ideapad S145-15IIL. The wireless card shows as a Realtek 8822CE on Windows.

The log at /var/lib/dkms/rtl88x2ce/5.7.3_35403/build/make.log shows

Can I get some help in order to fix this and get the wireless card working?

Re: Realtek 8822CE wireless driver issues

Please post the make.log for rtlwifi_new-rtw88-dkms failing to build.
Edit:
https://github.com/lwfinger/rtlwifi_new … 2e256206eb removed proc use so although the output may look similar the cause of the failure should be different.

Re: Realtek 8822CE wireless driver issues

The following modules were built:

As the module names do not match DKMS failed the build. So the dkms.conf appears to need updating.

According to https://github.com/lwfinger/rtlwifi_new/issues/582 the driver should only be used for RTL8723DE.

Re: Realtek 8822CE wireless driver issues

I see that the driver for 8822CE should be built at the kernel, but the interface of my wireless card isn’t showing.

Instead of using the AUR package I cloned, built and installed the package, this time with no error, but the interface is still not showing.

I already did «sudo modprobe rtw_8822ce». I see the mod_unload in vermagic but I can get it to load it (even using —force).

Maybe I’m looking in the wrong direction in order to solve this. Any idea?

Note: Please read «supported-device-IDs» for information about how to confirm the correct driver for your adapter.

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 system package information (select the option for the OS you are using)

Note: If you do not regularly maintain your system by installing updated packages, it is a good idea to not only update system package information but also to install the updated packages followed by a system reboot. The installation can then be continued with step 3.

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. You can skip this step if installing to x86 or amd64 based systems.

Run a preparation script

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

A file called 88x2bu.conf will be installed in /etc/modprobe.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 88x2bu.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 2.4 GHz: Set 20 MHz fixed width. Do not use 40 MHz or 20/40 automatic.

Channels for 2.4 GHz: Set channel 1 or 6 or 11 depending on the congestion at your location. Do not set automatic channel selection. As time passes, if you notice poor performance, recheck congestion and set channel appropriately. The environment around you can and does change over time.

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

Network names: Do not set the 2.4 GHz Network and the 5 GHz Network to the same name. Note: Unfortunately many routers come with both networks set to the same name. You need to be able to control which network that is in use.

Channels for 5 GHz: 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 5 GHzg. (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. You may have to test to see what the best location is in your environment.

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.

How to forget a saved WiFi network on a Raspberry Pi

Delete the relevant WiFi network block (including the ‘network=’ and opening/closing braces.

Press ctrl-x followed by ‘y’ and enter to save the file.

Question: What interface combinations does this driver support?

Answer: None. Realtek out-of-kernel drivers, including this driver, do not support interface combinations. If you need support for interface combinations, I suggest adapters based on the Mediatek chipsets.

Question: What extended features does this driver support?

Answer: None. For extended features, you need an adapter that uses Mediatek or Atheros drivers.

Question: I bought two rtl8812au based adapters and am planning to run one of them as an AP and another as a WiFi client. How do I set that up?

Answer: You can’t. Realtek drivers do not support more than one adapter with the same chipset in the same computer. However, testing has shown that the Mediatek drivers do support more than one adapter with the same chipset in the same computer.

Question: Why do you recommend Mediatek based adapters when you maintain this repo for a Realtek driver?

Answer: Many new Linux users already have adapters based on Realtek chipsets. This repo is for Linux users to support their existing adapters but my STRONG recommendation is for Linux users to seek out WiFi solutions based on Mediatek, Intel or Atheros chipsets and drivers. If users are looking at a USB solution, Mediatek and Atheros based adapters are the best solution. Realtek based USB adapters are not a good solution because Realtek does not follow Linux Wireless standards for USB WiFi adapters. Realtek drivers are problematic in many ways. You have been WARNED.

RTL8822x Firmware for GNU/Linux

The files in this repository are taken from Linux Mint 19.3 and will allow a Realtek RTL8822 b or c card to work on other distributions.

The files have been tested with Debian Live Testing ISO with non-free firmware included (https://cdimage.debian.org/images/u. firmware/weekly-live-builds/amd64/iso-hybrid/).

If you have trust issues, you can always boot with Mint 19.3 and take the files from there to use.

Log in with your favorite distribution, preferably with a new Kernel, as this has only been tested with 5.4+ Unload non-working modules from the Kernel, with:

modprobe -r rtwpci
modprobe -r rtw88

You can run lsmod to see if they are named somehow differently in your OS, in case you do not run Debian.

Copy the files from this repo to your system, change the kernel path as needed! Load the modules with modprobe rtw88 and the WiFi should work.

It is unclear to me whether the /usr files are needed or if everything will work with just the files under /lib. Feel free to open an issue about this.

Адаптер Wi-Fi не найден в ubuntu 18.04; нет драйверов для устройства rtl8822ce

Обновить

Ниже мой исходный вопрос с дополненной информацией. Первоначально я думал, что мое оборудование — это чип rtl8821ce, но, сравнив вывод lspci с этим постом, кажется, беспроводное устройство у меня есть, на самом деле чип 8822ce. Ранее заголовок этого вопроса не отражал этого факта, поэтому я его отредактировал.

У меня проблема, которую я не могу решить, и я был бы признателен за помощь. У меня новый ноутбук Lenovo IdeaPad, на который я недавно установил Ubuntu 18.04.4. К сожалению, Ubuntu не распознает мой Wi-Fi, говоря: «Адаптер Wi-Fi не найден».

Некоторые выходы:

lspci -nnk | grep 0280 -A3 :

rfkill list all :

sudo lshw -C network

Интересно отметить, что в выводах аналогичных команд в других сообщениях сетевой адаптер показывает: «RTL8821CE», а мой вывод — нет.

Что я пробовал до сих пор:

Сначала я попытался установить rtl8821ce-dkms вот так:

И я дополнительно отключил безопасную загрузку в BIOS. Это не подействовало. Ubuntu по-прежнему выдает то же сообщение.

Затем я попытался установить драйвер прямо с tomaspinho GitHub вот так (после удаления rtl8821ce-dkms):

Опять же, это не подействовало. Ubuntu по-прежнему выдает то же сообщение.

Интересно, что теперь, когда я бегу dmesg | grep -i 8821 , Я получил:

Я подозреваю, что, возможно, мое оборудование не поддерживается этим драйвером. Может ли кто-нибудь помочь мне понять, что мне нужно сделать, чтобы решить эту проблему «Нет адаптера Wi-Fi»?

Дополнительные попытки:

Как было предложено здесь, я попытался обновить версию linux-firmware пакет на моей машине. Я пробовал несколько разных версий, но ни одна не сработала. Что я сделал:

где » «Я пробовал быть:

• 1.173.16 (похоже, последний раз изменялся на сервере).
• 1,178
• 1.186 (последняя на данный момент версия).

Я все еще получаю сообщение «Нет адаптера Wi-Fi».

4 ответа

Наконец-то я нашел решение!(спасибо за ответ на этой странице).

Оказывается, драйвер, который должен поддерживать мое оборудование (rtw88), был доступен и совместим с этим оборудованием уже в ядре> 5.2 (у меня был 5.3.0-46-generic), но он не настроен на распознавание моего оборудования.Чтобы решить эту проблему, мне пришлось скомпилировать ядро ​​Linux с небольшими изменениями в исходном коде (шаг 2 в решении ниже). Вот что я сделал:

1) Получите исходный код Linux по вашему выбору. В моем случае я использовал основное ядро:

2) найдите файл: ./linux/drivers/net/wireless/realtek/rtw88/pci.c , и отредактируйте его. Ищите строку ‘0xC822’ и замените его на ‘0xC82F’

3) Продолжите компиляцию ядра в соответствии с инструкциями. Для полноты ответа вот что я сделал:

cd в папку./linux.

Используйте конфигурации из текущего ядра: cp /boot/config-$(uname -r) .config

Компиляция и установка:

я) make или make -j8 (чтобы использовать 8 потоков параллельно вместо одного). Это займет некоторое время.

II) sudo make modules_install .

iii) sudo make install

Включите ядро ​​для загрузки:

я) sudo update-initramfs -c -k 5.7.0-rc1+ . Конечно, использовать установленную версию ядра (в моем случае 5.7.0-rc1+). Если вы не уверены в версии ядра: «ls /lib/modules/» и посмотрите, какие модули ядра установлены.

II) sudo update-grub

Вот и все. Перезагрузитесь и обязательно загрузитесь с новым ядром. Теперь Wi-Fi должен работать.
