How to tell Windows 7 to use a different default network card ?

In the presense of multiple network adapters, it is sometimes necessary to manually specify which one is the default used for internet routing, for example. To accomplish this, you have to manually add a "metric" to each interface. Windows will automatically use the interface with a lower metric. To check and change your network adapters' metric:

1. Open Command Prompt and type: route print - you will see a list of active routes, the last column displaying their "metric". Lower metric routes are preferred over higher ones.

2. Open the Network Adapter Properties (Control Panel > Network and Internet > Network Connections > right-click on adapter and choose Properties)
3. Open the properties of Internet Protocol Version 4 (TCP/IPv4).
4. Click on Advanced.
5. Untick "Automatic Metric" and set the interface metric to a number.
6. Hit OK until you close the Network Adapter properties.
7. Repeat steps 2-6 for your other network adapter(s) choosing different metrics. Remember lower metrics are preferred over higher ones.

Check the new metrics in Command Prompt by typing: route print

thx thx thx !! I loosed 3 hours to understand why my Windows tried to reach Internet by another Ethernet card (which is dedicated to a Linux VM in bridge mode, so why it didn't work). This should be mentioned by Microsoft in their support website...

DHCP and static IP addresses will give different calculated metric values even if you set the metric value. I am not sure which is selected the calculated metric value or set metric value. So far this is working.

Brilliant thanks so much.

Köszönöm a segítséget!

Bár a cmd parancs win10 alatt nem mutatja megfelelően a metric értéket, de a sorrend megoldotta a problémákat...

Good Job! Thank You!

Great advice on Metric setting. Solved my dual LAN card problem instantly. Many thanks!

I worked around this challenge by assigning a 172.16.10.0/24 network to the router attached to the internet adapter and 192.168.1.0/24 to the internet router.

I also made sure to assign a static 172 address to the computer with both interfaces and remove the default route: i.e. I left it without a default gateway.

Hope this helps!

Great! Very useful and works for Windows 10 too.
I'm using this to run several VMs on my laptop using WMWARE and different NICs, but still, using only one NIC to send all my own traffic to Internet.
