Всем привет. Пользуюсь ноутбуком Asus X555L Ubuntu 16.04 LTS на протяжении 8 мес, вчера отвалился WiFi,до этого времени все беспроводные сети находил и работал отлично. Сейчас только через провод, wlan0 нет (беспроводные сети отсутствуют, пруфы: https://drive.google.com/open?id=1sZodNHzo2qYtWeg6qXQzIOuIkaf8z0AT )
