Я добавлял вручную (в случае с nm), по крайней мере, маршрут по умолчанию.
Всё-равно не работало. Маршруты же должны сами установиться, если работает DHCP?
И ещё до этого я задавал настройки конфигурации nm и вручную (в случае с одним
модемом там сложно ошибиться).

Кстати, модем его видит и arp таблице модема появляется запись.

В случае с интерфейсом, поднятым через ifup (с nm проверю завтра):

Есть опция log-level...
Вот, что он писал в syslog (где successfull, там уже, видимо, интерфейс был
поднят через ifup на этапе загрузки):
