Windows Connected but not working?

Well, I left my computer to fill out some important papers and now when I come back the internet was showing that it was connected with limited access but there was a red x in the connection panel.
When I tried going on the internet it said it was not connected, so I disconnected from my network and tried connecting, it still connected with limited access, I diagnosed the problem and this is what it said.

"The Network's adapter Atheros AR5007UG Wireless Network Adapter" is experiencing driver or hardware related issues.

Make sure your Internet Protocol Bindings are correct.

I've tried restarting the modem, restarting the computer and I can't update since my internet is not connected.

Appreciate the help.

Thanks.

Welcome
With another computer download the drivers that you think you need to a finger (USB) Drive.
Insert it in the problem computer and install from the USB.

Hi Arbaz,

In addition to what richc46 has mentioned, if drivers installation does not work, connect the same adapter to different a computer and check if it works fine.

If issue persists in the different computer, it might be an issue with the adapter which needs a replacement.

Please revert back for clarification.
