It’s a driver tool that detects, downloads and (if you go Pro) installs any driver updates your computer needs all automatically. To install your tablet drivers with Driver Easy, just click the Scan Now button, then when it detects the drivers you need to update, click Update. The correct drivers will be downloaded, and you can install them – either manually through Windows or all automatically with Driver Easy Pro. 5) Restart your computer and re-connect your wireless display adapter to see if it works. 1) On your keyboard, press the Windows logo key and X at the same time to invoke the quick-access menu. 2) Click Device Manager. 3) Right-click on your network adapter in Network adapters, here we take Marvell AVASTAR Wireless-AC Network Controller as the example.
