Lenovo tools for windows 7: can't re-enable wireless

This just happened to me on my ideapad. Go to Network and Sharing Center in the Control Panel, then choose Change Adapter Settings. That's where you'll see your wireless card is diabled. Right click on it and enable. Obviously a little late for the the original poster but this is for everyone else who finds the page.

The message seems to indicate that the master wireless switch is turned off. You don't mention this in your post. Unfortunately, I am not familiar with the exact model, but most of these machines have a physical wireless toggle switch on them - the software controls won't work if it's turned off.
