Wifi does not capture anything

I made a System Restore at the origin due to a virus and since the network connection could not capture any more simply. When I go to network connection that I do everything but didn't work.

Can you help me ?

Thanks

Here are my configure:

Windows Vista Home Premium (6.0, version 6000)
* ASUSTek
* Model: F5R
* Processor: Intel (R) Core (TM) Duo CPU T2250@1.73GHz (2 CPUs), ~ 1.73GHz
2000MB RAM

Select your product and select the driver in the wireless category http://support.asus.com/download/download.aspx

If you had CD's along with your laptop, look if you have one that says Drivers or pilots. At first your driver is not suitable for your hardware.

I try to install the wireless network card "Atheros AR5007EG Wireless Network Adapter"
but when I look in the Device Management wrote "Atheros AR5007EG Wireless Network Adapter # 2" with a yellow triangle and a central point "."

But it's still not working.

Go in the device manager and uninstall the driver for your wifi card, where the yellow exclamation point through the right click.After that install drivers.

When installing the driver will not be recognized as compatible, AR5007EG selections ATEHROS or AR5007G and valid even if a window indicates that the driver is not suitable.

It is likely that the button on / off wifi from your laptop does not work then, but normally you find the wifi.
