Renaming SSID on Netgear c6300

   C6300[v1] or C6300v2?  Look for "Model" on the product label.

   _Which_ "the SSID"?

   Here's a radical concept which works for some people:

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

   _Which_ "the instructions from Netgear"?

   None of that is a useful problem description.  It does not say what
you did.  It does not say what happened when you did it.  As usual,
showing actual actions (commands) with their actual results (error
messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.

   Clearly.
