Приветствую! Столкнулся с очень неприятным моментом. Wifi начал неожиданно отваливаться, либо переподключаться каждые 15 сек, либо фризиться. До этого проблем не наблюдалось.

Ядро: 5.16.16-arch1-1.

Из недавнего: поменял роутер, wi-fi работает в смешанном режиме 2,4/5.

Update: поставил lts ядро – проблема осталась.


Может там аппаратная проблема? Контакты не контачат, антенна из разъёма выскочила, бессвинцовый припой усы пустил и теперь коротит и т.д.

Рецепт:

  • yay -S downgrade

  • sudo downgrade --ala-only linux Находим 5.16.14 или 5.15.28-lts. Ставим. Перезагружаемся. Работаем.

  • До решения проблемы разработчиками используем обновления с опцией --ignore=linux.

А я думал, что ты не на арче… Downgrade же спрашивает игнорировать обновление пакета или нет. Можно еще найти нужный пакет на https://archive.archlinux.org/ и потом дать pacman -U link
