eibgrad,
Since this appears fairly recent, I thought I might tag along on this one. I'm currently using a WLAN for the internet connection. When I plugged in another router (another wireless router I am configuring), the internet connection ceased to function, presumably due to windows 7 prioritizing the wired connection. Removing the cable immediately restored connectivity.
Looking at the network configuration as described, I see the above. wired connections were already below the wireless ones, (though I did move the virtual wireless 3 connection below the 2, something I don't imagine is significant here.) In any case, this provided no route to solve the problem.
An image of the current settings:
Checking settings using using ipconfig (with both connections established) provides the following data:

Maybe I can find some help with this, or at least it might provide another data point for the other person's problem. If you or anyone else has anything useful, I'd quite appreciate it.
