Realtek RTL8811CU/RTL8821CU USB wifi adapter driver version 5.4.1 for Linux 4.4.x up to 5.x

Before build this driver make sure make , gcc , linux-header and git have been installed.

First, clone this repository

mkdir -p ~/build cd ~/build git clone https://github.com/brektrou/rtl8821CU.git 

Build and install with DKMS

DKMS 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.

To make use of the DKMS feature with this project, just run:

If you later on want to remove it, run:

Plug your USB-wifi-adapter into your PC

If wifi can be detected, congratulations. If not, maybe you need to switch your device usb mode by the following steps in terminal:

Need install usb_modeswitch (Archlinux: sudo pacman -S usb_modeswitch )

sudo usb_modeswitch -KW -v 0bda -p 1a2b systemctl start bluetooth.service - starting Bluetooth service if it's in inactive state 

Build and install without DKMS

cd ~/build/rtl8821CU make sudo make install 

If you later on want to remove it, do the following:

cd ~/build/rtl8821CU sudo make uninstall 

Checking installed driver

If you successfully install the driver, the driver is installed on /lib/modules//kernel/drivers/net/wireless/realtek/rtl8821cu . Check the driver with the ls command:

ls /lib/modules/$(uname -r)/kernel/drivers/net/wireless/realtek/rtl8821cu 

Make sure 8821cu.ko file present on that directory

Check with DKMS (if installing via DKMS):

ARM architecture tweak for this driver (this solves compilation problem of this driver):

sudo cp /lib/modules/$(uname -r)/build/arch/arm/Makefile /lib/modules/$(uname -r)/build/arch/arm/Makefile.$(date +%Y%m%d%H%M) sudo sed -i 's/-msoft-float//' /lib/modules/$(uname -r)/build/arch/arm/Makefile sudo ln -s /lib/modules/$(uname -r)/build/arch/arm /lib/modules/$(uname -r)/build/arch/armv7l 

Use the tool ‘iw’, please don’t use other tools like ‘airmon-ng’

iw dev wlan0 set monitor none

Миниатюрный WiFi USB адаптер Comfast CF-811AC 802.11ac/abgn 2.4+5ГГЦ (с разборкой)

Миниатюрный двухдиапазонный 2.4+5ГГЦ адаптер/донгл/свисток (нужное подчеркнуть), интерфейс USB2.0.
По умолчанию работает в режиме клиента, после установки дополнительного ПО — в режиме точки доступа.
Одновременно может работать только один диапазон, так что 650Mbps — это просто сумма двух теоретически возможных коней пропускных способностей в вакууме.

Поставляется в блистере с защелками, внутри картонки мини-CD с драйверами и ПО (сразу выкинул).
C обратной стороны напечатаны характеристики и сценарии использования.

Корпус адаптера имеет толщину 8мм, при установке вторым в «парный» порт не приводит к взаимным выгибаниям корпусов (как у меня было с Mi WiFi).

ТТХ

Собран на Realtek RTL8811CU
Стандарты 802.11a/b/g/n,ac
Схема 1T1R, с поддержкой MU-MIMO
Индикаторов активности нет.

Вид изнутри

Пошкрябаность была изначально, из коробки.


Общие впечатления

Маленький аккуратный адаптер, работает под win7 после ручной установки драйверов (возможно в 8х и выше подхватывается сам). При работе греется меньше чем Mi WiFi — на ощупь нет 40С.
В Debian/Armbian подхватывается автоматически. Поддерживаемые фичи можно посмотреть в iw list
