Как заставить 3g модем подключиться к сети?

Question

[MorozovNsk]

Всем привет.
Есть достаточно магическая ситуация, есть 16 одинаковых 3g модема (Huawei e352), 6 из них куплены чуть раньше, 10 чуть позже. Прошивка одна, версия одна, разница только в серийниках.
Устанавливаю соединение при помощи скрипта sakis3g.
Первые 6 отлично подключаются, остальные 10 не хотят.
Самое интересное в том, что насколько я понимаю ситуацию, все модемы отлично подключаются к сети, но вторая половина не может пройти авторизацию.

Куски дебажного лога sakis3g в которых начинаются отличия:

Я нуб в Linux и pppd, но мне кажется, что модем по факту успешно устанавливает соединение, нов одном из случаев не удается пройти аудентификацию.
Внимание, на эти строки лога, они есть только в случае успеха :
CHAP authentication succeeded: Welcome!!
CHAP authentication succeeded

Answer 1

[OvLab]

Может прошить неработающие прошивкой от работающих.
Знаю точно, что Билайновцы меняли прошивки модемов, чтобы они работали только через их GUI.

модем вроде возвращает одинаковую версию(там версия и дата компиляции возвращаются, они совпадают). В любом случае подскажи чем/как шить.

Answer 2

[Сергей Петриков]

Возможно вторая партия модемов залочена под определенного оператора, соответственно с картами другого оператора не работает, проверьте, например, через данную программу для просмотра статистики бесплатна и посмотрите в чем разница, если версия прошивки действительно одинакова.

Все модемы изначально лоченные на megafon (e352b), но это успешно полечено как раз при помощи данной программы, теперь все модемы сообщают, что лока нет.

Answer 3

[AlexeyR24]

Как говорили выше проверь, лочены ли модемы.
Проверь на другой системе, желательно винде.
Переведи модемы в MODEM ONLY, в никсе, реально жизнь облегчает.

подскажи чем подключаться к произвольному оператору с винды, пытался разобраться с этим вопросом, но с ходу ничего не нашел.

[Сергей Петриков]

Например с помощью этой прошивки rutracker.org/forum/viewtopic.php?t=4432571
