netmask 255.255.255.0
gateway 192.168.1.1
nameserver 192.168.1.1

Try with an other power supply.

my main supply can give up to 1.5A and i'm not using hdd also tried another supply and usb 2.0 from pc, the same thing.

I noticed it about a week ago and it doesn't start with launch of the system. Everything starts to go up\down after a random period of time.
