I have a fresh install of Ubuntu 16.10 (with kernel 4.8) and the network isn't connecting (via Ethernet). The machine is a new J3455B-ITX mobo/CPU combo.
Here's what ifconfig shows:
enp1s0: ///
lo: ///
My /etc/network/interfaces file looks like this:
auto lo
iface lo inet loopback
#
auto enp1s0
iface enp1s0 inet dhcp
netmask 255.255.255.0
Here's the output of services networking status:
Active: failed (Result: timeout)
Starting Raise networking interfaces...
waiting for lock on /run/network/ifstate.enp1s0
networking.service start operation timed out. terminating.
Failed to start Raise network interfaces
I'm stumped. Any ideas?

Seems that your computer is having two network cards, enp2s0 = RTL8168g/8111g, enp1s0 = Intel(R) PRO/1000
Are you completely sure that your ethernet cable is on Intel, not the realtek?
Seems that your cable is connected to enp2s0 not enp1s0. I made that conclusion of this line you show (see the no-carrier flag):
2: enp2s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 70:85:c2:4b:68:0a brd ff:ff:ff:ff:ff:ff
3: enp1s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
link/ether 00:1b:21:39:ed:64 brd ff:ff:ff:ff:ff:ff
I Suggest you try to replace your networking config to raise interface as enp2s0 with configuration like this:
auto lo
iface lo inet loopback
#
auto enp2s0
iface enp2s0 inet dhcp
Actually you don't need netmask, dhcp broadcast to 255.255.255.255 should go to every device on your layer2 network.

No carrier means there is no active line connected to your network card.

Do you have a DHCP server available for the enp1s0 interface? What means "netmask ...." in interfaces file as you want to use DHCP configuration?

Yes I already have a router on the network that is the DHCP server. The only reason I added the netmask was because I noticed in the logs it was searching for 255.255.255.255.

To be sure, if you have all required drivers (included firmware files) try to setup static IP (help.ubuntu.com/lts/serverguide/network-configuration.html) and check if you will have access to the internet.
