Multiple Wi-Fi cards and Internet connections on Windows 7

Question

I have two Wi-Fi cards and two separate Internet connections.

I connect to the Internet with both of them but one does all of the Internet transactions (and I have not seen any place where I can specify which one I would prefer to use!)

What I would like to do is use one of them for the browser and Skype only, and the other one for stock exchange software for instance.

Is this is possible?

Answer 1

This is not easily doable, your computer will have a local address (127.0.0.1 with a subnet mask of 255.0.0.0) and any traffic that needs to be routed outside of the address range (eg public IP addresses) will go to an adapter that has an external gateway. In this case you have two internet connections, both with external gateways. Windows will determine which one routes the data based off the interface metric (unless the traffic belongs to the subnet of the interface).

You would need some very specialised software to do this.

(and I have not seen any place where I can specify which one I would prefer to use!)

As I said above, Windows uses the Interface Metric. See here on how to change it.
