R7000 and D7000 - Can't access admin page

I've had repeated problems with the Netgear R7000 Router and D7000 Modem+Router not allowing me to access the admin page. When I type the IP into my browser (Chrome), I get a "connection refused" error: "192.168.1.[x] refused to connect" and "ERR_CONNECTION_REFUSED".  No joy in Internet Explorer either.  Interestingly, I have exactly the same problem on both devices.  I have no issue connecting to admin pages for other NG devices on the network - just these two Nighthawk devices. 

 

The devices otherwise generally work OK (although I've found the wifi on each to be quite sketchy - regularly dropping out).  They respond to ping - it is just the admin page I can't get on to.

 

I'm slightly at a loss as I've checked what I thought could be all the obvious points:

 

1. The IP address is definitely correct - all my devices have static IPs on the same IP network, and I can see from other devices on the network that the MAC address of the NG devices matches their IP addresses.  

 

2. I have tried connecting via Ethernet directly to the NG devices with nothing else connected - so it is not a wifi problem or a problem elsewhere on the network. 

 

3. I have also tried via WiFi with an iphone (Safari browser) - but still can't get the admin page to load.  The NG devices also don't show up in the NG Nighthawk app, even when I am connected directly to the device's wifi network. 

 

I have tried resetting to factory settings using the reset button.  That restores the admin page for a bit but within a day or so I'm no longer able to access it.  Exactly the same happens on both devices.  

 

When I recently reset the devices, I did do a firmware upgrade to whatever the latest version was (perhaps a few weeks ago).  But I have had this problem for some time before the firmware upgrade. 

 

Any suggestions as to what is wrong would be gratefully received.  Thanks.

   D7000[v1] or D7000v2?  Look for "Model" on the product label.
Firmware versions?  Connected/configured how?  Are we talking about two
networks or one?

   _Which_ "the IP [address]"?  Hiding local/private IP addresses does
not improve security, but does obscure potentially important
information.

   Where is your "my browser" running?  What is the IP address of that
system? And it's connected to what, how?


   "connection refused" normally means that you're communicating with
something, but there's no appropriate server running there.  (In this
case, a web server.)  There have been cases reported where the
management web server can die (for no good reason) on various Netgear
router models/firmware versions, typically the result of a firmware bug,
but it's unusual these days.


   Or, your (hidden) IP address could be that of some other device,
where no web server is expected to be running.

 

> [...] They respond to ping [...]

 

   From which IP address to which IP address?  Copy+paste is your
friend.

   _Which_ "The IP address?  The correctness of any of your secret
details might be obvious to you, but, with my weak psychic powers, I
can't see any of them.


   Terminology: A "static" address is configured on the device itself.
What you configure on a (DHCP server on a) router is a reserved dynamic
address, not a static address.

   "connecting" _what_ [...]?  And then what happened?

   Can't see any of those details, either.

   As always, an actual version number would be more useful than your
opinion of what's "the latest" today (or "perhaps a few weeks ago").

   Not enough useful information yet.

Re: R7000 and D7000 - Can't access admin page

Thanks for the reply - in answer to your questions:

 

- Will check the D7000 when I have access tomorrow. It was purchased 4-5 years ago - I suspect v1. 

 

- Don't know how to check the firmware version on either model other than by looking at the admin page (is there another way to find out what version is running?) --> hence my best guess that it was updated within the last few weeks. 

 

- Single network running linked together by 4x NG switches (3x unmanaged JGS516/524 and 1x managed GS724T).  I have also tried connecting directly to the NG Nighthawks (ethernet cable from Windows 8 laptop to the Nighthawk) with nothing else plugged into the Nighthawk - still doesn't work so I don't believe the problem lies elsewhere in the network. 

 

- IP address is the IP address of the relevant NG Nighthawk device - i.e. the static IP that I had given that device when I was able to access the settings.  I am not talking about an IP reserved or assigned on the DHCP server, but a proper static IP set in the particular device's settings. 

 

- The NG Nighthawk devices are definitely still using the IPs I have given them (set as static IPs in their settings when the admin pages worked) as (1) when connected to my wider network, I can see that IP on the network as attached to the MAC of the relevant NG Nighthawk and (2) when connecting directly to the Nighthawk via ethernet from laptop with nothing else connected to the Nighthawk or laptop, PING to that IP from the laptop cmd prompt still works.  Laptop is configured with its own static IP on the same network and subnet.

 

- Browser is running on Win 8 laptop, but I get the same error with a Win 10 desktop (again running Chrome). 

 

- When I say "connecting" below via ethernet or wifi, I mean trying to access the admin page via the browser.

 

From what you've said, it does sound like a bug with the management web server.  

 

Thanks

   Ok.  You win on that one (for now).

 

> - Single network running linked together [...]

 

   I'd guess that there's more than one way to "link together" all those
gizmos.  What, exactly, is connected to what, exactly?  (Hint: If a
device has different types of DSL/Ethernet ports, then"connected to
device" is not enough detail.)  Start at your ISP connection, and work
toward the client devices.

 

> - IP address is the IP address of the relevant NG Nighthawk device

   When configured as a router, one of these devices has two IP
addersses: LAN and WAN/Internet.  What are the actual IP addresses?

   Still can't see any of those numbers from here.

   I wouldn't rule out the possibility, but with only vague/no
information about how your network and devices are arranged/configured,
all I an do is speculate.  And life is short.

Re: R7000 and D7000 - Can't access admin page

Somewhat frustratingly, I have swapped the two devices round and they now work perfectly - admin page fully accessible, even after several days.  I have absolutely no clue why that is - both are connected via Ethernet into Netgear switches that are linked together with Ethernet.  So problem solved, but with no real idea why that is.
