Under enp3so I see only BROADCAST and MULTICAST, no UP or DOWN. Thanks
That means it's down. Note that you said enp3so above, that should be enp3s0 (zero); which did you put in interfaces? Also, there should be either "auto enp3s0" or "allow-hotplug enp3s0". Assuming that's all right, try manually running "ifup -v enp3s0".
