Iwlwifi/ru

iwlwifi — это драйвер для современных беспроводных чипов Intel.

Ядро
Чтобы заставить его работать, нужно сделать небольшую настройку ядра. Драйвер поддерживает 802.11a/b/g/n/ac (в зависимости от устройства), поэтому IEEE 802.11 должно быть включено.

Драйвер устройства iwlwifi
Используйте этот драйвер для беспроводных чипов Intel. Установите как модуль, как показано. Также необходим  DVM или MVM вариант согласно записи в колонке Module в таблице firmware.

Firmware
Also firmware for the individual device is needed as listed in this table. It is available in and in device-specific sys-firmware/iwlxxxx-*ucode packages.

Если собрано в ядро
In case the driver is built into the kernel instead as a module, also the firmware needs to be built into the kernel.

In this case replace  with the exact firmware name. Some attention seems to be needed for FW_LOADER_USER_HELPER_FALLBACK.

modprobe и modinfo
should return nothing:

Most information about the driver module can be obtained by

lspci
should display  for both   and.

The  identifier will be useful for grepping specific information from dmesg.

dmesg
Check the output of dmesg. Replace  with the info from lspci.

Firmware issues

 * For systems using udev or systemd, it is imperative to configure the kernel to load binary blobs. In this case the wireless card's firmware is the firmware that needs loaded. More information on configuring the kernel in this manner can be found in the following thread on the Gentoo forums: FW_LOADER_USER_HELPER_FALLBACK.
