   It's a miracle!  Who'd've guessed?

   Firmware version?  Connected to what?

   "can not" 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.

   Visit http://netgear.com/support , put in your model number, and look
for Documentation.  Get the User Manual (at least).  Read.  Look for the
LED descriptions and "Troubleshoot".  Pay particular attention to the
"WiFi On/Off button with LED".  Did you press it?  Further reading
might not hurt, either.

or what you did with it.

   "AX1800" is a speed, not a model number.  Look for "Model" on the
product label.  I'd guess that there's a User Manual for it, too.

> would someone PLEASE tell me what to do........

   You might try this radical concept which works for some people:

   Right.  Wired-good, wireless-bad is a local-to-you problem.

> cisco modem [...]

   Not a very detailed description of anything.  Has it a model number?

> i get internet via ethernet but no WIFI

   I got that much _before_ I asked any questions.  Plenty of other
questions still waiting for answers.  Look for "?".

   What does "email replies" mean to you?  Responses in this forum?

E-mail notifications of responses in this forum?  Other?

> [...] tried to follow through, [...]

   What does "tried to follow through" mean to you?  _How_, exactly?

> [...] i received authentication failed messages, [...]

   From what?  When you did what?  Actual message?  Copy+paste is your
friend.

> [...] just want to mention that,

   That's fine, but the non-psychics in your audience might not be able
to guess what you're talking about.
