помогите разобраться почему пропадает инет с T77W968 модемом

[meine12]

не могу понять где копать. пропадает периодически интернет и все вешается намерво, хотя есть резервный канал.

здесь лог от роутера с 968-м модемом, он ланом воткнут в mesh сеть

в 15:34 инет пропал, ночью в 0:30 ожил и отстучался в телеграм

Потому что:

May 20 00:29:58 ndm: UsbQmi::Interface: "UsbQmi0": connection lost.

А почему бы не настроить pingcheck c restart-interface?

Здравствуйте! Нашёл только эту тему в инете. При нагрузках, например впн на роутере и далее удалённый рабочий стол и работа в браузере вызывает отключение интернета. Он просто пропадает. Через несколько минут пропадает индикация на модеме и минут через 5-7 интернет снова появляется. Сейчас не выдержали нервы, разбил новый ноутбук huawei...((((

[meine12]

опять возвращаюсь к этой же теме. пингчек стоит автоматический, он не помогает

[meine12]

помогает at+cfun=1,1, но это я подключаюсь через sstp - захожу телнетом и пишу interface UsbQmi0 tty send at+cfun=1,1
 

может есть способ быстрее и проще?
