My Canon printer (Canon MG3600) because I haven't even been working for a long time since I have a new wireless network. I have already tried to reconnect the printer, it works but unfortunately it doesn't matter what I do.
I don't know my way around at all, I would be grateful for any help.
Which operating system do you use?
Try to reinstall the driver for the printer. As far as I know, the network connection is also set there.
Either you enter your new Wi-Fi password on the printer.
Or you connect the printer to the printer via a USB cable, install the Canon software and use it to set up the WLAN.
Unfortunately I don't know how to reinstall this driver.
