2 How to use dongle
Miracast(WFD) and DLNA/Airplay are running on the different WIFI working
models. Miracast’s connection is over WiFi direct and DLNA/Airpaly’s
connection is over WiFi softap(hotspot). These two WiFi working models are
not able to be concurrent. In this chapter, each features of the dongle will be
described first and then showing how to switch modes between two WiFi
working models.
2.1 Miracast(WFD)
Power on the dongle and wait until the status “Waiting for connection...”
appears. Meanwhile, make a connection request from WFD source device, i.e.
mobile phone. About the operation on WFD source device, please refer to
chapter 3 for details. When connection between the mobile phone and the
dongle is established, WFD source device’s MAC address, IP address and

device Name will be shown on the screen as the picture below.
2.2 DLNA
1) Connect to dongle
Enable WiFi on the mobile phone/laptop/tablet, search for the AP with the
SSID named by dongle’s device name, for example, LOLLIPOP-80833.
Dongle is now working as a soft AP. So connect to the soft AP with the
default password 12345678.
2) Connect to Internet
Upon the connection between mobile/laptop/table and dongle is completed,
open web browser on the mobile phone/laptop/tablet and visit
http:\\192.168.49.1. What you will see is as below.

Touch “Scan” and follow the instructions to connect to a WiFi AP which is
able to access Internet through WAN. Please pay an attention that when the
connection between dongle and AP is established, the connection between
dongle and mobile phone/laptop/table may be disconnected. The reason is that
the connection channel between dongle and mobile phone is different from the
channel between dongle and AP. In this case, mobile phone/laptop/tablet
should be connected to dongle by soft AP again.
