Я пытаюсь подключиться к Интернету с помощью LTE Stick от Huawei (e3372). Я установил usb-modeswitch, ppp и wvdial. Modewswitch работает правильно. Устройство смонтировано на /dev/ttyUSB0, где я могу отправлять AT-команды. Я хочу подключиться с помощью wvdial, но он всегда говорит: «Демон PPP умер: модем повесил трубку (код выхода = 16)». Консольный вывод моей команды wvdial:
