I'm puzzled. My sister's laptop was working fine until she made a password and forgot it. I re-installed Windows 7 for her, fixing the password problem, but in the process her laptop decided it no longer wants to connect to the internet.

I'm typing this on my own laptop, on which my wireless is working fine.

All it says are that no connections are available. I've tried using Windows Troubleshooting, but it's only told me it's missing a driver but can't connect to the internet to find it because it doesn't have that driver! It's driving me crazy.

I've also tried FN + F2, which is supposed to toggle wireless, but it doesn't do anything. The light that is supposed to indicate that the wireless is turned on won't do anything, even flicker. I tried plugging in two different cables from my Router into the laptop to try to use wired internet, but it won't recognize those either. In the Device Manager, there is a yellow mark next to Network Controller, which also tells me there is no driver installed.

It's a DELL Inspiron. Can anyone help me?
