2. Connect to WiFi: On your smartphone, search for a WiFi network starting with OMG_.

3. Enter the password: Click on the network and enter the last 8 digits of the device's MAC address as the password (the MAC address is printed on the side of the device). For example, if the MAC address is 409151234678, the password will be 51234678.
