Router Web Page refuses to connect after updating settings

   Still not thrilled by it.  (What's the actual error message from the
web browser?)

> Firmware version: V1.0.0.51_1.0.1

   This must be some new meaning for "the latest".  I see
"V1.0.0.53_1.0.2" on the server.

   Relying on Netgear firmware to "Check for new version from the
Internet" is like relying on Netgear firmware for anything -- the result
is often disappointment.

   Visit http://netgear.com/support , put in your model number, and look
for Downloads.  (For older versions, under Firmware and Software
Downloads, look for "View Previous Versions".)  Find the kit(s).
Download the kit(s) you want.  Read the "Release Notes" file for
instructions.

> > Reset router:
> I mean power cycle

   That's not the common meaning of "reset" in this context.

   Visit http://netgear.com/support , put in your model number, and look
for Documentation.  Get the User Manual.  Look for "reset".  It's far
from a sure thing, but it's possible that a settings reset (and manual
reconfiguration) would help in this case.  (Restoring saved settings
could restore old problems.)

   Wrong forum.  It's in the list at:
      https://community.netgear.com/t5/x/bd-p/home-dsl-modems-routers

But yes, that firmware version agrees with "v2".  (Netgear "Community"
forum organization and administration are on a level similar to its
router-firmware quality.)

   It's worth a try, but a reproducible error is always easier to fix,
and a bug which never gets formally reported may never get fixed.

> I will try and older firmware version

   I'd start with the newer one, and than start working backward.
(And/or a settings reset.)


> Yes this is a minor issue, [...]

   I disagree, but it would bother some users more than others.
(Especially those with remotely operated equipment.)

   Netgear routers have some history of management web servers dying
with little or no provocation.  I don't recall reading of any cases of
this on a D7000v2, but that proves nothing.

> [...] Maybe my expectation is too high for a consumer grade router.

   I'd say not.  My D7000[v1] (currently V1.0.1.70_1.0.1) is not
bug-free, but can't remember ever catching its web server dying.
Generally, if that happens, it's a bug.
