   You might find some relevant information in a widely neglected
resource:

      https://en.wikipedia.org/wiki/RTFM

   Visit http://netgear.com/support , put in your model number, and look
for Documentation.  Get the User Manual (at least).  Read.  Look first
for "Types of logins".  Further reading might not hurt, either.
