I'm looking for a way to use at the same time wired and wireless interfaces.
My situation:
- 1 Gbit ethernet interface (10.100.x.x)
- 1 WiFi 802.11 b/g/n interface (192.168.x.x)
- The PC is part of a domain (10.100.x.x) and I logon using a LDAP user.
I want to use the Ethernet interface to connect to the domain and navigate through LAN, but every time I need to access the internet, I want to use the WiFi.
The Ethernet interface is configured for the domain, so there's a DHCP that assigns every setting, from PC IP address to default gateway IP and DNS.
I tried almost everything...
- "Advanced settings" on "Network Connection Panel" to change the interfaces order.
- Route table to adjust interfaces and gateways metrics.
- "Network Adapter Advanced Settings" to uncheck the automatic metric and set a manual value.
When both my interfaces are activated this is my Route table

The best I was able to obtain was to set a manual metric value to the Ethernet interface so the metric of gateway increased till a value greater than the WiFi gateway. This way lead me to gain access to the Internet by the WiFi gateway (as I wanted) BUT I loose my network connections access so I cannot access my domain resources (server, shares, printers...).
Using the procedure described above I finally have this Route table

Here the WiFi gateway (192.168.x.x) has lower metrics than ethernet one, so I can go to the WAN with that but I cannot access my network resources anymore.
It seems that with that route table, every LAN connection tries to pass through WiFi interface.
I tried to change and delete the 0.0.0.0 0.0.0.0 10.100.1.1 10.100.1.55 276
route but nothing appened...
1Why are you trying to use metrics? Why not set a route to (10.100.x.x/16) via the wired NIC and the only default gateway via wireless? – Hennes – 2016-08-06T12:39:04.797
Regarding dual network setup, (one for Internet, one for corporate/work), also see this question: https://superuser.com/questions/450493/changing-routing-on-mac-with-two-ethernet-ports. (Same network principles apply to windows as well).
