Wow this is frustrating.  Updated from firmware 1.05 to 1.07ww.  I do a factory reset, and it takes me through the set-up wizard.  I change the password.  I modify all my setting as desired, all seems fine.  However, once I exit, I cannot log back in with the password I've just created:  "Invalid password, please try again."  Factory reset, go through the entire process again, same result.  I've done this several times.  This is not a very fun way to spend a Friday night.  This is with Firefox 49.02 with all extensions and add-ons disabled.  Any suggestions?
