Resetting a Netgear Model R7300

   "unable" is not 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.

   The non-psychics in your audience might not be able to guess what you
were reading, or where on which "the website" you might have found
anything.  Regarding "to no avail", see "not a useful problem
description [...]", above.

   I'd expect a settings reset to remove any/all custom settings.

   Visit http://netgear.com/support , put in your model number, and look
for Documentation.  Get the User Manual.  Read.  Look for "Factory
Settings" or "Reset".  Further reading might be useful, too.
