The Ethernet IC(0424:9730) driver seemed to be loaded correctly.

What happen if you do up/down the eth1 ?

Up/down...does not change anything.

Yesterday i installed android, to see if there is the same situation...but unfortunately is the same...ethernet disconnected.

I noticed one thing....sometimes when system boots up, green led flashes twice.

Pin in eth socket looks fine...i'm wonder if maybe the socket is broken? I thought to replace it...but i do not know if it's worth...
Any idea how to bring it back to life?

I have no idea. Sorry about that.
It is very hard to know whether the RJ45 jack is broken or not.

Only for information, ethernet card isnt dead.
I have installed meveric debian version and my card is back to life.
So i think its software problem.
