I recently changed my Network name on my router, as a result my printer no longer connects to it wirelessly. I have attempted to go into the settings of my HP MFP M477fdw but it prompts "Password." I tried entering the router password but that didn't work. I recall setting it up over a year and a half ago but can't remember if I set an administrative password or what it would even be. Can someone please help? Thank you in advance!
