I signed in with “admin” and the password being “password”. Prompted me to change password so I did. Upon trying to save, it tells me old password is incorrect. I try to try it again, still tells me old password is incorrect. I refresh the page and I put in old password and this message shows up. I type in the new password I wanted and still tells me the same. How do I get around it so I can change my Wi-Fi password?
