Canon MX452 Air Printer...

[NorPlan]

I'm a Newbie to this Forum and have Posted my Query on the Canon Thread..I'm trying to cover my Bases , unfortunately I'm somewhat Computer Illiterate and do my best to read & follow by number and in the correct order too..My problem stems from the iPad reading it Can't Find the Printer...With Instructions in hand following the setup prompts to a Canon MX452 Air Printer, the Hic Up is the WEP key...I do have the correct WEP key but the Printer shows Invalid WEP Code...What am I doing Wrong ??? Thanks....
