Michael, after numerous tries at setting up a wi-fi connection to our computers at home following the horrendous directions that came with the printer, I finally came across your post here and succeeded. Thank you for your help. But the technical writers at Canon need to figure out a way to get that simple point across in the user guides.
To have a better understanding of your issue, please let everyone know what operating system (Windows Vista/7/8 or Mac OS 10.X) you are using. Also any specific error messages you may be getting and if they are from the printer or the computer. That way, community will be able to assist you with suggestions appropriate for your product.
