Someone on here had a work around for a MB2320, so I thought I would try it for my Pixma MX490......and it worked!
1. Unplug the printer
2. Unplug the modem ethernet from the router (You could also turn off router)
3. Plug in the printer - it will turn on by itself, cycle, and it may take a minute or two, but the menu screen on the printer will display without turning off.
4. Plug the modem ethernet back into the router
It worked! I am not sure if I will have to do this every time I turn on my computer to print something, but at least I not only have a work around until Canon fixes the issue, but at least I CAN PRINT WHEN I NEED TO!!!
Turn off your router and once that is done, turn the printer off and back on. The printer should start back up and then you can disable the wifi in the printer. Once that is done, power your router back on and then connect the printer to your computer via a printer usb cord and then try the firmware update.
