NetworkManager & WiFi II

продолжая эпопею с WiFi наблюдаю взаимоотношения NetworkManager-а с беспроводными сетями.

есть у меня в пользовании две сети (с которыми я регулярно общаюсь), обе скрытые, одна при этом без защиты (wifi_1), другая работает в режиме auto WPA & WPA2 (wifi_2).
NM в общем случае вроде как умеет их сам находить, но как-то неуверенно... периодически он их теряет и приходится подсказывать ему руками.

другой неприятный момент, что с wifi_2 он не может нормально договориться. не помогает перевод сети в статус WPA only.

примерный монолог NetworkManager-а выглядит так:

Mar 15 18:45:36 junkyard NetworkManager: wlan0: link timed out.

непонятно зачем - теоритически брелок должен быть уже разблокированным - NM каждый раз просит его разблокировать (один раз на сеанс).
почему-то NM быстро сдется и не может подключиться к сети (закономерности не выявлено, но происходит это часто...), хотя рядом лежит КПК под Windows mobile 6, который подхватывает эту же сеть без слов.

неопределенное число попыток и...
