ubuntu server 10.04 интернет по pppoe
периодически начинают пропадать пакеты, сеть тормозит, потом вообще перестает пинговаться, потом дисконнект и не держит соединение больше минуты
рестарт сети не помогает (/etc/init.d/networking restart)
лечится только передергиванием сетевого кабеля в сетевую карту
сетевую карту меняли, проблема осталась.
в логах ничего подозрительного
в какую сторону копать? в чем может быть проблема?
