I called Canon, this happened Tuesday to a whole lot of people. Here is the solution:
SOLUTION: After a 1:57 hold time with Canon customer service.... I have the solution! (and that was 2 hours, not 2 minutes) If this is happening to you it is very easily fixed. [Removed per forum guidelines] Although I wish I could sell it to make up for my 2 + hours of time. Here is what you need to do to fix it:
Completely unplug your router and then turn on your printer (it won't stay on if your router is because of a linking problem with the router, that we are going to fix.) So this is the step-by-step for the MG6620 and probably those models with similar menus, but whatever model you have just try to get to your DNS Server Setup. That is where the setting is that needs manually changed. So for the MG6620:
On the menu swipe to Setup, then find Web Service Setup then DNS Server Setup. Select Manual. Press each set of numbers and change them all to 000 except the last set. That needs to be 001. So your DNS will look like this: 000.000.000.001 Click OK, then click No.
That's it. You should be good to print.
You are welcome! Too bad someone at Canon doesn't just post this somewhere. Would've save a lot of people a lot of headaches, I'm sure.
