NetworkManager буянит?

Question

[Николай Медведков]

Здраствуйте.
У меня на Debian NetworkManager периодически теряет соединение, потом через несколько секунд переподключается и соединение появляется.

Как сделать, чтобы соединение не терялось?

Answer 1

[SunTechnik]

1. Как часто это повторяется? Насколько регулярно? (например, каждые n минут)

2. Какой lease-time выставлен на dhcp server?
3. На статику можете переключиться?

Answer 2

[CityCat4]

Как на дебиане - не знаю, на генте подобное вылечилось удалением конфига /etc/conf.d/net и заменой его на просто кусок текста без команд. Возможно NM и обычный dhcpd дерутся.
