Билайн интернет дома: модем Icon 225

Проблема с настройком модема Icon 225.

Все вроде как ок, при попытке коннекта интерфейс hso0 поднимается, ip, роутинг и dns назначается, но через пару секунд отрубается (интерфейс остается поднятым, но модем начинает мигать, что означает что он не подключен). За эти пару секунд можно сделать ping ya.ru - он успевает заресолвиться и если повезет проходит один пинг.

Потом пытаюсь подключиться вот таким скриптом:
