PIXMA TS6420a is connected to my Spectrum Router but it is considered to be offline by the Canon App

I can print attaching my Mac to it by a usb cable, but, I cannot print thru the WiFi Network! My IPads don’t see the printer on the network.

Unlike many Canon printer yours does allow WIFI and USB to operate at the same time. The printer needs 2.4ghz wifi, it will not connect to 5ghz. Make sure your router has 2.4ghz active.

Thanks for joining the conversation, jeffwltrs!

So that the Community can help you better, we need to know exactly which Canon printer model you're using within the TS6400a series. The model number should appear on the front of the printer at the lower right. That, and any other details you'd like to give will help the Community better understand your issue!
