What is the model of your system? The following support page lists the correct order of driver installation. Your drivers would be on the support page of your system. Enter your tag number on the support page for the drivers for your exact system.
If the system does not have Wi-Fi, you should connect it directly to an Ethernet cable or you should download the Wi-Fi driver to a USB key using another device and then install it on your Alienware system.
