A:Answer The instructions show how to mirror Android phones and tablets, along with Windows 10 and 8.1. This device worked great mirroring my Android phone and tablet, along with my computer (Windows 10). I didn't need any wifi just as the manufacturer states. My phone, tablet, and computer picked up the device very quickly. My iPad needs wifi though as it does not put out a mirroring signal like Android and Windows. I checked all of the screen casting and mirroring instructions with my iPad, and it definitely will not mirror without wifi.
