Всем привет, тема вроде банальна, даже ветку закрепили, но решить так и не смог.
Ubuntu 20.04.3 LTS без объявления войны перестала видеть Wi-Fi. В GUI-настройках беспроводная сетевая карта отсутствует.
Это ноутбук, ethernet-адаптера в нём тоже нет, так что ноут оглох и ослеп.

Позавчера всё работало, систему вроде не обновлял, новый софт не ставил.
Прошу помощи.
