Ubuntu update 15.04 now no network enp3s0

[Pok Salid]

New to Ubuntu and very upset that a system update killed my Ethernet network. Thank god I have this old windows laptop to find help. It appears that eth0 has a new build enp3s0. Nice... no fore warning no options, just throw the d*mn thing into the system and let everyone else worry about it. That is P!ss Poor Programming.

I found a video on youtube that helped me get my ethernet up...But on reboot the damn thing crashed again. I tried system recovery from backup, crashing the program to rebuild....nothing helped it just comes back..saying you have the latest update installed....thanks WiFi on my combo card works and I can print to my network printer.

/etc/network/interfaces - edited to Auto enp3s0 /// iface enp3s0 inet static /// adresses and masks set to my system

Resolv.conf edited to map? networks - it worked but file was reverted back after reboot.

reboot and Ethernet Network device not managed error

/etc/networkManager/NetworkManager.conf Managed=false //// Ethernet Network device not managed ----error
/etc/networkManager/NetworkManager.conf edited to list Managed=true

back to no network

How can I get my Ethernet Network back on line when the update changed Eth0 to Enp30?

Wifi is no longer an option. set all files to what they were on upgrade. Settings>Network> "the system network services are not compatable with this version"
