Thanks Simon,
I mean rest of the processes are working but only ethernet related functions stops working.
It's my first project with LwIP so dont know from where to start debug.
Now as you suggested I'll try to get data from lwip_stats first.

Thanks again.

That's hard. First, I don't know what "stops working" means. Then: no way to tell from here. Get a debugger and start searching what's wrong. "lwip_stats" might help you.
