New R7000P will not get to password prompt

After I set up my router, I on to it to change the default password.  I entered the default password, but then I was aked to answer secret questions that I never chose before - default questions?  "What's your younger sister's name?" So I did a reset on the router.  Thereafter, Win 10 found the networks (low/high).  One network displayed Connected no Internet.  When I disconnected/connected, I never got past the checking connection window, and then nothing.  And I can't log in to the router, either.  So, what next?
