I'm sorry about the issue. What happens when you go through the wireless setup on the printer's screen? What happens when you enter your new wireless / wi-fi password ***** the printer? Is there any error or message?
Do you mean you have lost your wpa password ***** your wi-fi / wireless password?
What is the model of your Internet modem/router device?
Do you have a laptop / wireless computer that is currently connected via wireless? If so, does it have Windows xp, vista, or 7, 8, 10, or Mac?
Please reply at the box below. Thank you.
