R6620 will not connect to Canon printer when WPA security enabled

[MosgielColin]

I have a Canon Pixma G3610 printer that will not connect by WiFi to my R6620 router. 

When set Security Options to "None" then the printer can be connected, and available for printing to from computers on the same network.

But when reset Security Options to WPA2-PSK then the printer disapears from the network.

I do not want to operate my WiFi without security enabled.

Any advice please

Have you cleared the wifi settings on the printer and tried to connect again with WPA2 enabled? Also, can the printer use WPS to connect?
