Thinks 
First ,  There is no iptables severing no my box;
Second : The /etc/resolve.conf keeps the same all the times;
I tried to restart   network , eth0 , dhcpd, NetworkManager but nothing helps,The same thing happens whilel using static IP address.
I've attached Wiresharp data ,Hope someone can help.
