How do I connect to two networks (wired and Wi-Fi) at the same time?

Question

at office i need to connect to local resources through wired network and internet thought wifi. I had tried enabling settings/network/ethernet/advanced settings/IPv4/Routes/Use this connection only for resources on its network. and i got the lan conection but the internet connection sometimes work and sometimes not, then i just need to unplug the cable, reload the browser and when i get back internet connection, replug the cable. Also i had tried looking for the ip route getting only the wireless conection as default:

default via 192.168.0.1 dev wlp3s0  proto static  metric 600 
192.168.0.0/24 dev wlp3s0  proto kernel  scope link  src 192.168.0.105  metric 600 
192.168.1.0/24 dev enp2s0  proto kernel  scope link  src 192.168.1.208  metric 100 

In ubuntu-gnome 16.10 i got this working but in elementary loki i got this problem.

Some ideas about it?

Thanks in advance!

PD: Sorry for my bad english

Answer 1

i had solved this by adding some lines to /etc/network/interfaces

auto enp2s0
iface enp2s0 inet dhcp
metric 601

where enp2s0 is my wired interface and 601 is the new metric having wifi 600 metric.
