Common Wireless Communication Issues and Steps to Troubleshoot Them
There are many reasons that your printer may be indicated as being "offline" or "not responding". Basically, the printer and computer are not able to communicate. Since there are multiple causes for these messages, there are also multiple possible resolutions. The steps below will help in resolving the issue and possibly identify the cause.
Select the Appropriate Printer
Restart the Printer
In some cases it may be necessary to power cycle the printer to potentially reset any error conditions or lost communication.
Reboot Your Router / Modem
If your router and/or modem is not able to communicate with devices that are usually connected, you should power cycle the router.
Reboot Your Computer
In some cases, it may be necessary to restart your computer to refresh connections with the various peripherals such as routers, modems, printers, etc.
Reinstall the Printer Driver
To all. Canon over the phone helped me to resolve problem.
After doing all the above maneuvers without result, agent tested I try a different browser and... all worked fine. My Chrome browser had been corrupted. So: Uninstalled Chrome, then reinstalled, and computer connects to printer fine and prints all aspects properly now.
Lots of hours wasted. My router does not reboot fast enough for the printer wireless setup timeout. Tried using USB to setup wireless but it ends up asking for my Admin password. I cannot think of any reason for this other than it gives Canon and its individual employees unrestricted access to my computer. I have tried calling customer service but got the message to call back later. I have like the various Canon printers for many years, but this experience tells me I have made a mistake and need to send this printer back.
My problem started with the new router. I tried unplugging/repluging everything possible. No good. Did the above and reinstalled the driver. No good. Realizing the drivers were for the older Mac OSs, I finally found
That did the trick.
