Eu tenho o Ubuntu Ubuntu 16.04.1 LTS com kernel: 4.4.0-45-generic.
Eu tenho o modem USB stick refirmwared para a empresa celular possui o modem.
O problema é que, muitas vezes, eu preciso de vários minutos para reinserir o dispositivo, reiniciar o computador e / ou reiniciar o gerenciador de rede, para obter a opção de banda larga móvel no widget NetworkManager na parte superior da tela ...
Talvez você possa sugerir drivers ou outra solução?
