dreambox 500s strange lan problem

[neo17]

Hi mates.

I have a dreambox 500s with a strange problem.

Lan card is not working as it should. The box is not communicating at all.

In my router i see the light of the lan port to be on for 2 seconds and then off for 2 seconds, and then this thing again.

In dhcp the box dont receive ip, and if i configure the ip manually the box wont communicate.

I have tried to reflash with no success.

Does anyone have any idea??

Thnx in advance.

One more thing, the 2 lights of the lan card inside the dreambox stays always on without flashing.
