You're welcome. And I thank you for the large can of red herring in
your problem description.

That's too "In short". And what about the non-Wired network?

"Won't" 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.

Did you notice that I did not participate in that conversation, and
have no idea of its contents?

I might have gotten distracted by the pointless Telnet nonsense,
which did not demonstrate a failure. I didn't look very closely after
that.

Always? Occasionally?

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".

To what is the router connected? Some kind of modem or ONT? Have
you tried bypassing the router, and connecting directly to that? How
did you decide that the router is at fault, and not some other gizmo?

Have you tried the usual panacea, a settings (misnomer: Factory)
reset and manual reconfiguration?

I fail to see any red hearings, but let us go through this further.
“And what about the non-Wired network?”
Sorry I hadn’t explicitly stated this, good point. Yes Wireless connections work perfectly.
When using a Wireless connection with the same device (So unplug the net cable on my computer and use wireless (Same device)) and all traffic works.
Note also, I have attempted to use the wired connection with the Wireless card disable to ensure there is no case of asymmetric routing, and this didn’t address the issue.
“"Won't" is not a useful problem description”
That is true, but
If I browse to something the error returned is “ERR_CONNECTION_RESET” or “ERR_CONNECTION_CLOSED”
Is a useful problem description with the two additional factors of
I still get DNS returned, and if I perform a Telnet to a host,
&
“wired connections still work perfectly for resources inside my network”
“I might have gotten distracted by the pointless Telnet nonsense”
That telnet “nonsense” was to show that there is still a connection of sorts, it will resolve DNS, it will route traffic to a target, so discarding it as nonsense seems to be counterproductive
All symptoms are consistent, none of them are intermittent
In terms of the LED Indicators they are flashing white for all connections, no evidence that the router believes there is an issue
“To what is the router connected? Some kind of modem or ONT”
A Cable Modem
“ Have you tried bypassing the router, and connecting directly to that”
No, because the router works fine when using wireless.
“How did you decide that the router is at fault, and not some other gizmo?”
Because the router works fine when using wireless.
“Have you tried the usual panacea, a settings (misnomer: Factory) reset and manual reconfiguration?”
Yep, at least 5 times now.
Any thoughts?

     My impression was that you were complaining about the time-out error.
  Not answering the question ("What makes you think that that behavior is
  abnormal?") didn't clarify what you intended to show. When you're
  complaining about comm errors, a test which shows a comm error is not
  obviously a demonstration of success.
  
  > [...] Wireless connections work perfectly.
  
     That's much more significant than any cryptic Telnet experiments.
  
     How many different wired devices exhibit the same problem(s)?

     "Same device", but not, I'd guess, the same IP address. And it is
  different hardware.
  
  > "wired connections still work perfectly for resources inside my

     Does that include between a wired and a wireless device?
  
     I've never seen it, but I can imagine a hardware problem in the path
  between the router's LAN Ethernet stuff and its WAN side. Wired-LAN to
  wired-LAN could work through such a problem if the network switch is a
  relatively independent functional block.

     If I were desperate, then I might try loading the old firmware one
  more time, doing another reset and manual reconfiguration, and verifying
  that multiple wired devices suffer from the same misbehavior. In that
  case, I'd tend to suspect the hardware.
  
     Assumptions:
  
      "If I browse to something" means multiple popular sites (Google,
        Netgear, ...)
  
  More than one computer/device exhibits the problem.
  
  No conflicting (static?) LAN IP addresses.
  
     Definitely not something I've seen or seen reported.

    So.
    An update.
    I Returned my router under warrantee. I set up the network on the new router.
    I had tested connections to the internet via a wired connection and they worked.
    I let the router performed a Firmware update.
    And…
    The Same Fault Occurred
    Firmware V1.2.1.22 on a Nighthawk RAX120 is An Issue.
    Do Not Install it.
