It take a long time to download the presentation, why is that?

The DROID ZX Player can connect to the internet via Wi-Fi or Ethernet. If you use Ethernet (Ethernet dongle sold separately) you will enjoy extremely fast download times. However, Wi-Fi connection requires a good nearby wireless hotspot to operate smoothly. If your Wi-Fi connection is slow, we highly recommend that you get the Ethernet dongle and enjoy quick response times.
