Why is there a QR Code on the rear side of the router?

Good news, every router is sold with a sticker that contains the Wi-Fi network information such as the Wi-Fi name and its password. You may have noticed a QR Code next to it. This QR Code is designed to simplify your connection to the Wi-Fi. Indeed, if you open your smartphone and scan the QR Code you will be automatically connected to the Wi-Fi of your device.

Once you have changed the Network Name and Password of your router, the QR code will not work anymore as the connection information of your router will be different.
