[SOLVED]Cubieboard Ethernet Network Issue

[c0d3s]

Hi, today i installed on my cubieboard the latest archlinuxarm version (27-08-2013) and after i added the latest hardware pack from sunxi. The system boot and i'm able to display something on the screen, but i have an issue with ethernet connection. I enabled dhcp on ethernet connection and it work but after some minutes cubieboard disconnect from network and it wouldnt connect again (try to unplug and replug the cable) but ethernet connector led remain on.
How can i fix this problem?

There is a couple of similar issues here. It seems to be a hardware issue with faulty ethernet port. Your issue seems similar to OP's. Check your power supply or try power the board via USB OTG port.
You might need to replace your cubie if its faulty
