У меня есть Dell m3800 с Intel Wireless 7260.

Я обновил ноутбук с Ubuntu 19.04 до 19.10 с помощью do-release-upgrade и network-manager больше не работает. Моя сетевая карта в порядке, если я загружаюсь в Windows или использую 19.10 установщик Ubuntu.

network-manager подключится на очень короткое время. Значки сети на панели задач переключатся на « ... » (никогда не подключался), и Интернет будет работать (иногда минуту, иногда меньше), и, наконец, появится уведомление о сбое сетевого подключения, и оно снова отключится. Панель Wi-Fi настроек gnome скажет «Wifi-Unavailable» или «Unavailable 802.1x supplicant failed»

Мне пришлось установить wicd , чтобы получить стабильную сеть.
