Do you assume that driver whiz is the cause of this?
I assume you "uninstalled" it through control panel/programs and features?
How about this:
download and install Revo Uninstaller
reinstall driver whiz, but don't run it.
use Revo to then immediatley uninstall driver whiz, using it's capability to dig into the registry and root out any last remnants.
Then try to reestablish networking through ordinary means.
I've used the "reinstall then immediately uninstall" thing to get around problems before and it worked.
But I'm stabbing in the dark. Who knows what registry changes may have been caused by driver whiz.
How does Device Manager look? Can you revert to older drivers there?
