To connect to the Wi-Fi, refer to the Quick Guide here.
Turn on your Wi-Fi router, then turn on the Wi-Fi setting of your own device.
On the Wi-Fi setting on your device, you will see the SSID of the router; choose that SSID and enter the password. The connection will be established.
*To see the SSID and password, see the back side of the router. It is written above the QR code.
*IMPORTANT*
If you are using a smartphone or tablet, please turn off your data roaming.
If you leave it on, it will connect automatically to a roaming network that would cost you a high amount of money.
