You will find the drivers for your laptop model on the manufacturer's website (that's Asus I believe).
Using a different PC which has internet access, go here and choose appropriate country:
https/www.asus.com/entry.htm
When the country-specific page has loaded, click "
Service" at the top, then click "
Support" below that.
Now enter model name/number of your laptop & click the magnifying glass icon.
Download the drivers on to a pen drive, then plug the pen drive in to your laptop to install them.
