Hi my name is ***** ***** I will be the expert working with you today to help and resolve the problem you have posted.
Try to install the printer on your computer and while selecting wifi you can enter the password ***** your computer and that will take care of the issue.
you dont need to change the wifi router password ***** you do is install the printer on your computer and it will automatically pick the password ***** if not you can enter the password ***** your keyboard to sync with the router.
you can enter the password ***** your printer as well all you have to look for is to press which key to get special characters on your printer screen in that case.
Installing from a computer will be the easiest way to get the printer on a network.
