This isn't completely true. Windows has no control over how other systems connect to a multi-homed computer. On a laptop with both wifi and wired networking, incoming connections for remote desktop sessions or network file transfers could reach either the wifi connection or the wired connection.

If you're leave a laptop connected via a wired network with the intention of connecting to it from another computer, you should disable the wifi adapter to make sure your connection goes over the (much faster) wired connection.

I could be wrong - but as I understand it, the ability for one operating system to combine the bandwidth of more than one network interface card at a time requires software/drivers that will merge the data streams and the cooperation of the hardware (router) that the NICs are connected to.

However, you can have several Virtual Machines running at the same time - each using a different NIC.

You do not have to turn off the wireless to do that.

I don't know how you checked this but if you open Task Manager and click the Networking tab you can see which adaptor Windows is using.

If it truly does perfer to use your Wireless I found some info here that will help, Windows 7 - Why is the Network Adapter Priority ignored while - Microsoft Answers, in the post marked Answer at the top.

The only thing is there are two Metric settings one at the bottom and one under Default Gateways. If both adaptors are assigned Gateways then this will be the one that controls internet access, the one at the bottom most likly controls other network access like connecting to another computer.

Obviously if only one has a Gateway assigned then it will be the only one that can access the internet.

EDIT: Don't know how this will go disconnecting/reconnecting the cable. Whether or not it will retain the setting, mainly when using DHCP I would think static IP's should be ok.

as im finding answers I tried it few minutes ago both connected from wireless and cable, and as I looked from the task manager, it only uses wifi connection not the lan cable...

timlab1955,
When you make it back to this thread - please try this:

Go into device manager*
find and double click on the entry for your wireless NIC
click on the tab named Advanced
see if you can find "Disable Upon Wireless Connect" in the list of properties
