Windows 7 - Limited Access to wireless network, Automatic update Error

Hello, I have this problem with my new Asus laptop which was fine yesterday, but cannot connect to any wireless network now. When I click the Network connections button on my task bar it shows me my internet connection with the words Limited Access next to it. I've been on google for a good 2 hours and can't really find the answer.

I may know what's wrong, however. Yesterday I pressed the shutdown button on my laptop and then it starts those automatic updates that happen when you shut down. It said something like "Updating 1 of 1 updates". It took a while so I put the laptops screen down, and when I checked on it again 5 minutes later... Blue screen. I held the power button down on my laptop and shrugged it off.. but now I can't connect to any wireless network.

Assuming the network driver is the thing that was updating last night, I searched up what to do, Rollback the driver to a previous edition. Still doesn't work.

As you can see, i'm a new user here and I need my laptop for University so please help

Ok... So no one has a way to help? I'm just about to uninstall my driver for the Atheros AR9002WB Wireless network adapter and install the driver again using the disk i got with the asus laptop.. Please tell me this is the right or wrong thing to do I don't want to destroy my new laptop.

And also, I already called Asus and they said they would call back asap, which they didnt.
