How to change wifi router password on Maxify MB2700

[rsquared]

I have tried everything but getting a new printer and I am still unable to find how or where to change the wifi router password in my printer. Other than throwing it out the window how can I accomplish this.  When we switched routers, I kept the same name but changed the password and now I cannot get my printer to connect.  Thank you for your assistance.

Different printer (MX472) same problem.  The only thing that's been offered is "use WPS setup" which isn't an option for me.  Resetting the printer to "factory" does nothing to help.  Not sure how to get a real response Canon as they seem to not care about this at all.
