AC1750 Smart Wifi router not broadcasting a signal, says its offline

[dasbill2020]

So bought this newer modem and has been working fine since we bought it. Now the Nighthawk app says the its offline. I have read to check the firmware but it keeps saying its not connected to the internet. I have it plugged into the comcast Bridgeway modem (which is in Bridge Mode) via LAN. I have tried even our old modem but it says not connected. 

Anyone have any ideas on how to get this back online to check the firmware or how to get the modem to stay online?

Your a waste of time and you should stop trolling. So some of us dont speak networking or know all the proper terms, you dont have to be so brash or arrogant. But that's ok because I dont spend my time wasting it on waiting for you to answer instead of lenghty conversations.

   Is that accurate?  R6700[v1], R6700v2, or R6700v3?  Look for "Model"
on the product label.

   Does that modem have a model number?  What, exactly, does "via LAN"
mean to you?  An Ethernet cable from some port on one gizmo to some port
on some other gizmo, or what?

   Does your "our old modem" have a maker and model number?  Again,

   When in doubt:

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

   Visit http://netgear.com/support , put in your (actual) model number,
and look for Documentation.  Get the User Manual (at least).  Read.
Beyond the basic set-up instructions, look for the LED descriptions and
"Troubleshoot".

   If problems remain, then something like "not working" 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.

- R6400 v2

   What, exactly, have you read?

- On the forums on the site, about people having the same issue, however I cannot get the modem connected to the internet so I cannot check my version of the firmware of the Wifi router.

mean to you?  An Ethernet cable from some port on one gizmo to some port

- Ethernet, what else would that mean. the Netgear modem is connected to the ethernet port or LAN. Just as it is read.

- It is apparent it is not the modem, there's seems to be issue with comcast modems and Netgear wifi routers

- Switiching out all enthernet cables, even switched out the comcast cable modem. 

- I have tried following steps that one of the forums here listed to the letter and I am at a loss. 

- Again the issue appears to be with comcast cable modem (just says its a Gateway cable modem)

   Thanks for the helpful links.

   You don't need an Internet connection to talk to your own router.

   Did you?

   "LAN" and "wired" are spelled differently for a reason.

   "LAN" = "Local-Area Network".  That would include both your wired and
wireless connections.  The LAN Ethernet ports on your router are labeled
"LAN".  There are no places to hang labels on wireless connections, so
they are not labeled "LAN" in the same way, but they're still part of
your LAN.

   It may be apparent to you.  With my weak psychic powers, it's not
apparent to me, hence the question.  I'd expect it to be easier to
answer the question than to argue about how irrelevant the answer might
be.  My time is apparently more valuable to me than it is to you.  I'd
prefer to waste less of it this way.

> - I have tried following steps that one of the forums here listed to

   Again, with my weak psychic powers, that tells me exactly nothing
about what you did or what happened when you did it.

   Did I miss something, or do we still not know what the LED indicators
on the R6400v2 indicate?  Plenty of other unanswered questions, too.
Look for "?".

> [...] (just says its a Gateway cable modem)

   It has no maker or model number?  Really?
