корпорация Intel: Dual Band Wireless-AC3168NGW [каменный пик ] Wi-Fi не работает на ubuntu

Question 1

Я установил ubuntu 20.04LTS. Мой ноутбук - HP probook 645 g4, amd ryzen7. В этом ноутбуке используется Intel wireless ac3168NGW для использования Wi-Fi. После установки ling Ubuntu, «Дополнительные драйверы» в программном обеспечении и обновлении, показывает, что корпорация Intel: Dual Band Wireless-AC3168NGW [Stone Peak] - это устройство не работает. и дайте мне возможность продолжить использование установленного вручную драйвера. Я пробовал 2 распространенных решения. Вайфай приходит и внезапно отключается. После отключения в разделе Wi-Fi в системных настройках отображается, что адаптер Wi-Fi не найден. и пропала кнопка включения-выключения Wi-Fi. Это действительно больно. Я дал 2 решения ниже. Они не работают идеально. если кто-нибудь предложит мне идеальное решение,

my-try-1:

wget https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-3168-ucode-22.361476.0.tgz
tar xvf iwlwifi-3168-ucode-22.361476.0.tgz
cd iwlwifi-3168-ucode-22.361476.0
sudo cp iwlwifi* /lib/firmware
sudo modprobe -v iwlwifi

my-try-2:

sudo apt update
sudo apt install linux-generic-hwe-20.04

и .. Я не использую двойную загрузку. Я установил Ubuntu на весь свой жесткий диск. Результат "dmesg | grep iwl" ниже.

Question 2

В вашем редактировании мы видим много повторений:

iwlwifi 0000:02:00.0: Microcode SW error detected.  Restarting 0x2000000. 
iwlwifi 0000:02:00.0: Start IWL Error Log Dump:

. Существует очень длительный отчет об ошибках о сбоях прошивки и Intel 3168: https://bugzilla.kernel.org/show_bug.cgi?id= 204151 Предполагается, что проблема фиксируется в ядер версии 5.5 и позже. Я считаю, что Ubuntu 20.04 LTS использует версию 5.4 ядра.

Я предлагаю вы загружать ISO для Ubuntu 20.10, который в настоящее время использует версию ядра 5.8. Далее попробуйте в реальном времени, также известный как «попробуйте Ubuntu».

Ваша беспроводная работа, как и ожидалось? Есть ли подсказки в журнале сообщений?

dmesg | grep iwl

делают все другие функции; Это электронная почта, веб-браузер и т. Д. Работает, как и ожидалось? Если это так, я предлагаю вам установить его.

Редактировать : Пожалуйста, проверьте целостность файла прошивки:

md5sum /usr/lib/firmware/iwlwifi-3168-29.ucode

Мы надеемся, что вы видите: 35ba5d5a8bdd6ff453106d268eda953106d268eda957e

Если нет, пожалуйста, сделайте:

sudo apt install –reinstall linux-firmware

Перезагрузите и проверьте:

dmesg | grep iwl

Любое улучшение?

Если нет, переименовать версию -29, чтобы система вместо нагрузки -27:

cd /usr/lib/firmware/
sudo mv iwlwifi-3168-29.ucode  iwlwifi-3168-29.bak

перезагрузиться. Есть ли улучшение? Если нет, верните изменение и перезагрузите:

cd /usr/lib/firmware/
sudo mv iwlwifi-3168-29.bak  iwlwifi-3168-29.ucode
