соединение pppoe (не АДСЛ). после падения переподключение невозможно. помогает только выключение системника минут на 15.

[AnrDaemon]

lshw -C network
ifconfig -a

до и после отключения.

Похоже, у вас драйвера не встали на сетевую карту, либо по какой-то другой причине система считает, что сетевая карта пропала. (Перегрев чипа карты?)
