У меня есть Ubuntu Ubuntu 16.04.1 LTS с ядром: 4.4.0-45-generic.
У меня есть перепрограммируемый модем флешки для сотовой компании, которой принадлежит модем.
Проблема в том, что часто мне нужно несколько раз переустановить устройство, перезагрузить компьютер и / или перезапустить менеджер сети, чтобы получить опцию Mobile Broadband в виджете NetworkManager в верхней части экрана ...
Может быть, вы можете предложить драйверы или другое решение?
