##If you face Networking error when you stop NetworkManage, Then you need to troubleshooting on network.
##Actually, By default you system access internet or networking using NetworkManager service, But when you stop/disable 
NetworkManager service then you need to enable/start network service. Then need setup network ip manually with MAC Address, Device Name, NM_Controled=no, IPADDR, Prefix, Gateway, DNS. Then using ifup [interface name], then restart network service.Then check internet or networking. its may be solved.
