My PIXMA MG 3620 printer is suddenly not connected to WiFi and when I try to connect it on my iMac, it's not on the list of printers in System Settings. When I try to start over and set up the printer via the Setup download, I'm asked for my password. I've tried all the passwords I can think of that I had associated with Canon, as well as with Apple. Every time I try to install something now, I'm asked for a password, but there's no indication of WHICH password! (I seem to have four just for Apple.) Can anyone help? Thanks.
