TS9020 has lost wireless conection

[pres64]

Our Canon TS9020 lost its wireless connection overnight. On the printer screen there is a red X on the wireless portion.  We have tried multiple connections and restarts.  Our wireless router is working with other devices.  I have watched the Canon videos, but they just tell me how to set it up.  

Any advice on why my wireless connection disappeared and how resolve this issue.  We have a Macbook running OS 10.14.4

@pres64,

The steps above should get you out of the situation you are facing now.

Additionally, once the printer is reconnected, give it static IP on your router.  Either by assigning it an adress based on its MAC or by giving it an IP above or below your DHCP pool. 

Why? Doing this ensures your printer's IP will never change.  Your router will always give it the same IP , regardless of how oftern it is used, turned off, goes to sleep, etc.

Other devices on your network will always be able to "find" and print to the printer because it's IP will never change. This is a reliable method for ensuring you always know the IP of your device.
