Step 1: Identify Your SSID and Network Encryption Type
For a QR code to connect directly to your Wifi it has to know what is your Wifi's SSID and the network encryption type. This helps QR code to direct smartphones to your Wifi from other connections.
To identify the SSID of your Wifi, go to the Wifi settings page and click on your Wifi. The name of your Wifi displayed on top of the page is your SSID. Be careful while noting this, SSIDs are case sensitive.
Network encryption is the kind of security your internet connection has. The most commonly used security is WPA2, WPA, and WEP. Identify which level of encryption is your Wifi at.
