Currently no Windows 8 Wi-Fi drivers for Elitebook 2740p are available. You have to wait for some time until they are released. For the time being, you can download Windows 7 drives instead and try to install on Windows 8. Follow the link given below from where you can download Windows 7 Wi-Fi drivers for this product.
