IP changed when I moved the cable, how do I get back to original IP?

I have been using this WNDR4000 Wi-Fi router for several years now with no problems whatsoever, until yesterday.

Here's what I did. I wanted to move this router to a different location in the house. I began by uplugging the cable from the host modem and the two cables serving a Netgear RN410 Nas.This router was only used for Nas access and for wireless devices.

I then plugged in the two Nas cables into the switch that is served by the host modem. Now the trouble became apparent.

I first get a disply on the Nas of 'STRNFAULT-10' if I remember correctly, on the Nas display. I realize something changed and began putting the cables back where I had found them. Nothing changed and I also could no longer log into the WNDR4000 router.

I log into the host modem and look at the connections. I find that the Netgear router had changed from IP port 2 to 56. I try to log into the Netgear router with the new IP and it fails. Rebooting the router changes nothing. I am panicking at this point.

 

Does anyone know how to get back the original IP for the Netgear router and more importantly, the Nas ips with ports 4 and 7?

I say ports, meaning the 4th or end number of the IP number.

   Understood, but as that step-by-step procedure to configure any
router as a WAP should make clear, configuring a WNDR4000 as a WAP is
not especially simple.


>> It was not hard to do. Basically I just gave the WNDR4000 a different name

for the SSID and turned both radio frequencies on. The FIOS G-1100 uses it's DHCP

to assign any wireless connections through the WNDR4000/N750.

 

The WNDR4000 shows no internect connection which used to confuse me until

I understood that the FIOS G-1100 was not configured in bridge mode and I had

only extended the network from the LAN port of the FIOS G-1100 to one of the

WNDR4000's LAN ports.

 

I think it's really a great piece of engineering that one router can serve IP addressing

through to another router in this fashion.

   Why "two cables"?

   What is your "the switch"?  What is your "the host modem"?

   Was it configured as a router or as a wireless access point?

 

> [...] Now the trouble became apparent.


   So far, the only thing which is apparent to me is that, other than
the WNDR4000, I have no idea what any of your equipment is, nor how any
of it is connected to the rest of it, nor what any of the relevant IP
addresses might be, nor what any LED indicators might be indicating, nor
anything else which might qualify as useful information.

 

   A cable has two ends.  Where do your cables go?  (Hint: If a device
has different types of Ethernet ports, then "connected to device" is not
enough detail.)

 

> [...] I also could no longer log into the WNDR4000 router.

 

   When you did what, exactly?  "could no longer" 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.


   Starting from some computer or other, which was connected somehow or
other to something or other, using some web browser or other, and some
URL or other, you got some kind of error or other?


> Does anyone know how to get back the original IP for the Netgear
> router and more importantly, the Nas ips with ports 4 and 7?

 

   Who knows what that "the original IP [address]" was?  If you expect a
device to keep the same IP address, then you might look for "Address
Reservation" in the WNDR4000 User Manual.  (Visit
http://netgear.com/support , put in your router model number, and look
for Documentation.  Get the User Manual.  You might also try that for
the NAS gizmo, whatever it might be.)

 

> [...] I am panicking at this point.

 

   Apparently, and it's not helpful.  A clear, accurate, concise
description of what your equipment is, and how it's all connected, would
be a better way to invest your time.  (And waste less of everyone
else's.)

 

> I say ports, meaning the 4th or end number of the IP number.


   "ports" means something different to everyone else.  Inventing your
own technical terms (especially when they conflict with existing ones)
is not the best way to communicate.  And, with multiple routers
involved, the rest of any IP address might be significant, too.

 

   Also, there are forums for NAS devices:

Re: IP changed when I moved the cable, how do I get back to original IP?

Thanks for your reply. After reading through the manual and various other posts here in the forum, I was able to get the Nas up and running again and am able to connect to it to see the shares/files, etc.

 

What I did was shut down the Nas then plug in the two ethernet cables (Yes, it has two ethernet ports) to my D-Link eight port switch and then power up.

 

On to the WNDR4000/N750 router.....

 

Reading through 'how to reset' I then performed a reset. After waiting for the lights to settle I connected one end of an ethernet cable to the 'Internet' port of the router.and the other to my ethernet port on my laptop. I then typed in the browser, 192.168.1.2. After a few seconds or so I get a screen that informs me to check the cable and connections, so on and so forth. Sorry, I did not take a screengrab to give here or to type in the details. I tried the sequence once more and get the same results. I'm sure the first thing I needed to do was to check this cable to make sure it was a good working cable. I did test it by connecting it from the desktop computer in the office on one end and connecting the other end to the FIOS router and it proved it was good. I could browse the internet and log into the FIOS router, browse the net.

 

So, at this point I am at a loss as to what to do next.

Re: IP changed when I moved the cable, how do I get back to original IP?

Update: Moments after posting the above I decided to try again. I don't know if leaving the router powered down overnight did the trick or what, but now after connecting the laptop to one of the router's ethernet ports and browsing to 192.168.1.1 I got the screen that gives me three options (if I remember correctly) to set up the router. I selected the option to allow me to do the setup. I could then see the menu selections on the side of the login splash screen as normal.

 

I then selected to restore from a backup configuration file that I had saved back on December 30, 2019. The router successfully restored the file, the lights flashed indicating to me that it is all back to where I started from before moving cables around. I checked for the SSID with my phone and do see the correct SSID's for 2.4 and 5G signals. I will next plug in the router to the D-Link switch after placing this router at the front of my house as I had originally started off to do before I got into trouble. This has been quite the learning experience and I have to thank the original, one and only replier to my post for pointing me in the right direction. Hopefully after moving and plugging this router into my switch everything will be good to go and we can close this discussion.

   I would not expect that to work.  The router _LAN_ Ethernet ports are
where you should connect a client device like your (unspecified) "my
laptop" (or your (unspecified) NAS).

which is good.

   Optimists are so cute.

 

   I assume that your (unspecified) "the FIOS router" provides your
Internet connection, and that you've connected one of its LAN ports to
one of the ports on your "my D-Link eight port switch", and that you
have some computers and/or other gizmos connected to "the FIOS router"
directly and/or to the switch.  Which should all be harmless.


   The next problem will arise when you add the WNDR4000 to this
arrangement.  If you simply connect the WAN/Internet port of the
WNDR4000 to one of the ports on your switch (or directly to a LAN port
on the main router -- they're practically equivalent), then, by default,
the WNDR4000 will create its own little subnet, and you can expect
trouble with communication between devices which are connected to the
LAN side of the WNDR4000-as-router, and devices which are connected to
the LAN of main router.  If you try it, then I'd expect you to see a
whole different set of IP addresses on the WNDR4000 LAN ("10.0.0.*", not
"192.168.1.*").

 

   If you want all your devices to talk to each other on one
big/extended LAN, then you'll need to configure the WNDR4000 as a
wireless access point.  Sadly, as I read the WNDR4000 User Manual, it
doesn't have a convenient one-step option to let you do that.  That
doesn't make it impossible, but it does make it rather complicated.
(And you thought that what you'd already done was educational.)  There's
a step-by-step for this here:


      https://community.netgear.com/t5/x/x/m-p/1463500

 

That's written for a C6300-as-WAP, but the steps are about the same for
any other router (any make/model) which lacks a one-step WAP option.  It
does require you to do a little work on the main router, too.

 

   Many newer Netgear (and other) routers have more convenient WAP
configuration options, so you might have less trouble with something
other than a WNDR4000 in this role.  In the User Manual for a Netgear
router, look for a section title like, "Set up the router as a WiFi [or
'wireless'] access point".  For more helpful pictures, fetch the R7000
User Manual, and look there.

 

   I'll bet that this sounded easy when you started out.

   Might be possible. I haven't investigated that device.


   The important thing is to have one router, not two.  That means that
you can disable the router functions of the G-1100, by putting it into a
"bridge" mode, or else you can disable the router functions of the
WNDR4000 by configuring it as a WAP.  If you put the G-1100 into
"bridge" mode, then the only thing which you can connect to it would be
the WNDR4000-as-router -- all the client devices would need to be
connected to the WNDR4000-as-router.  With the G-1100-as-router and the
WNDR4000-as-WAP, you could connect client devices to either of them.

>> Sorry, I have got to quit being so general, thinking everyone

I would be connecting to one of the LAN ports on the G-1100 FIOS

router. It has two of these ports available. One of them I connect an

ethernet cable to and the other end connects to an 8 port D-Link switch.

I now have an ethernet cable that connects from that switch and then the other

end is connected to a LAN port on the WNDR4000 router mounted on a

wall in the garage. The second LAN port on the FIOS G-1100 is now unused.

>> You say this is important but the problem is this FIOS G-1100 router

sits in the far left rear bedroom/office and the signal starts to get weak

the farther you walk to the front of the house. This was the reason I moved

the WNDR4000 to the garage, closer to the front of the house and to serve

the Nest Connect device which talks to the Yale Nest front door lock and any other

future device(s) I may place in that area in the future. I cannot find a place to

centrally locate the FIOS G-1100 router.

 

So far the Nest Connect has stayed online for days now since I trouble

with it previously staying online as I described earlier in this thread.

 

Years ago there was no good way to put two routers on the same SSID and

placed far apart to give good coverage in a household without problems I read.

I never tried it so I don't know for certain. Nowadays you can upgrade to a 'Mesh'

system from what I have been reading. But, I like many others do not want to

have to spend the coin if we don't have to.
