Windows 7 laptop with an built-in wireless NIC and USB 3G device. If the wireless network connection fails I want to automatically kick over to the 3G connection. I can have both running at the same time no problems, but whenever they are the internet connection always goes out through the 3G connection rather than the wireless. I have tried "internet options" setting, or prioritising the connections through the network and sharing center, all with no luck. I think this can possibly be achieved through the command prompt and the "route" command but I can't figure out how to do it.
Any thoughts would be much appreciated.
