Как установить драйвер для W-Fi для карт с чипсетом RTL8814AU (Alfa AWUS1900)

Какой чипсет в Alfa AWUS1900

Чипсет RTL8814AU имеют следующие W-Fi адаптеры:

• Alfa AWUS1900
• TRENDnet TEW-809UB
• ASUS USB-AC68
• TP-LINK Archer T9UH
• D-Link DWA-192

Они особенно полюбились тем, кто тестирует на безопасность Wi-Fi сети, поскольку это современные беспроводные адаптеры, которые могут переходить в режим монитора и выполнять беспроводные инъекции.

Лучше из этого списка является Alfa AWUS1900.

Раньше в драйвере realtek-rtl88xxau-dkms присутствовала поддержка для чипсета RTL8814AU и для работы этих карт достаточно было установить указанный драйвер — на Kali Linux это можно было сделать прямо из основного репозитория пакетов, на других системах нужно было компилировать. Но теперь для чипсета RTL8814AU поддержка в драйвере realtek-rtl88xxau-dkms отключена! Для этого чипсета сделан отдельный драйвер, который может конфликтовать с RTL8814AU! Эти изменения произошли недавно, поэтому старые инструкции по установке драйвера для Alfa AWUS1900 не работают.

Если вам не нужен драйвер realtek-rtl88xxau-dkms (поддерживает теперь чипсеты RTL8812AU/21AU), то удалите его:

Если он вам нужен, то можете не удалять и проверить, будут ли они конфликтовать.

Как установить драйвер Alfa AWUS1900 (RTL8814AU) в Kali Linux

Для установки драйвера RTL8814AU выполните следующие команды:

Скачайте исходный код драйвера:

Установите драйвер как модуль DKMS — это означает, что при обновлении ядра вам не придётся вручную перекомпилировать драйвер под новую версию ядра. Это автоматически будет делать модуль DKMS. Также обратите, что команда make не нужна, поскольку компиляцию выполнить модуль DKMS.

Чтобы драйвер заработал, может потребоваться перезагрузка.

Обратите внимание на строки:

DKMS сообщает, что установка завершена и что статус для 8814au «установлено».

Если вы захотите удалить этот драйвер, то перейдите в папку с исходным кодом и выполните там:

DKMS сообщает, что установка завершена и что статус для 8814au «установлено».

Удаление драйвера

Чтобы удалить драйвер из вашей системы, откройте терминал в каталоге с исходным кодом и выполните следующую команду:

Переключение между режимами USB2.0/3.0

Изначально драйвер будет использовать режим USB2.0, который ограничит пропускную способность 5G 11ac (ширина полосы USB2.0 только 480 Мбит/с => пропускная способность около 240 Мбит/с). Но когда modprobe добавляет параметры «rtw_switch_usb_mode=1» в опции инициализации драйвера 8814au, то он переключится в режим USB3.0.

Переключение usb2.0 => usb3.0

Переключение usb3.0 => usb2.0

Как перевести Alfa AWUS1900 в режим монитора

Главное, что нужно уже усвоить, используйте команды «ip» и «iw» вместо «ifconfig» и «iwconfig» — это касается работы со всеми Wi-Fi адаптерами.

How to install driver for Wi-Fi for adapters with RTL8814AU chipset (Alfa AWUS1900)

What is the chipset in Alfa AWUS1900

The RTL8814AU chipset has the following W-Fi adapters:

• Alfa AWUS1900
• TRENDnet TEW-809UB
• ASUS USB-AC68
• TP-LINK Archer T9UH
• D-Link DWA-192

They are especially loved by those who perform wireless security testing of Wi-Fi networks, since they are modern wireless adapters that support monitor mode and can perform wireless injections.

The best on this list is the Alfa AWUS1900.

Previously, the realtek-rtl88xxau-dkms driver had support for the RTL8814AU chipset and for these wireless cards to work, it was enough to install the specified driver – on Kali Linux this could be done directly from the default repository, on other distributions it had to be compiled. But now RTL8814AU chipset support is disabled in the realtek-rtl88xxau-dkms driver! A separate driver has been made for this chipset, which may conflict with RTL8814AU! These changes are recent, so the old instructions for installing the driver for the Alfa AWUS1900 do not work.

If you do not need the realtek-rtl88xxau-dkms driver (now supports RTL8812AU/21AU chipsets), then uninstall it:

If you need it, then do not delete it and check if they will conflict.

How to install the Alfa AWUS1900 (RTL8814AU) driver in Kali Linux

To install the RTL8814AU driver, run the following commands.

Download driver source code:

Install the driver as a DKMS module – this means that when updating the kernel, you do not have to manually recompile the driver for the new kernel version. This will be done automatically by the DKMS module. Also note that the make command is unnecessary since the compilation is done by the DKMS module.

A reboot may be required for the driver to work.

Pay attention to the lines:

DKMS reports that the installation is complete and that the status for 8814au is “installed”.

If you want to remove this driver, then go to the source code folder and execute there:

Start by installing the pikaur program according to the “Automatic installation and update of AUR packages” article. The pikaur program is analogous to pacman, but for working with the AUR, it allows you to automatically install and update programs from the AUR. You will definitely love pikaur!

Then run the command:

How to set Alfa AWUS1900 into monitor mode

The main thing to learn by now is to use the “ip” and “iw” commands instead of “ifconfig” and “iwconfig” – this applies to all Wi-Fi adapters.

USB2.0/3.0 mode switch

Initial it will use USB2.0 mode which will limit 5G 11ac throughput (USB2.0 bandwidth only 480Mbps => throughput around 240Mbps). When modprobe add following options will let it switch to USB3.0 mode at initial driver:
