D7000 Not allocating Reserved IP to Device

[DaveOLW]

D7000 V2   V1,0,0,51_1,01,   Windows 7 64 bit

A Device (WIZ1x0SR1E7EA6)  is on all the time, D7000 keeps giving it a different IP Address, I have a IP Address set in the Reserved List but it does not give it that Address.

Why does it keep changing IP Address and why will it not give it the Reserved Address?

   So, it's really a "D7000v2"?

   If it's "on all the time", then when does this mystery "A Device" get
a different address?  When the modem+router restarts, or when?

   That looks wrong.  If you shut down everything, then start the
router, and allow only the mystery "A Device" to connect to it (and, I
suppose some computer with a web browser at some safely distant
address), and the mystery "A Device" gets the wrong address, then I'd
tend to blame the router firmware.  (Reports of bugs in D7000v2 firmware
are not unheard of.)

   If some other device on the LAN had been configured with a static
address of ".4", and the DHCP server noticed that and (cleverly) avoided
the conflict, then that might explain something, but I'd expect any such
trouble-making gizmo to appear in the Attached Devices list at the
conflicting address.  (Unless it was removed after the trouble was

made.)

   Another possible explanation would be the presence of another DHCP
server on your LAN.  If you disable the DHCP server in the D7000v2, and
no one can get a dynamic address, then that would seem to rule out that
hypothesis.

   Around here, on my D7000[v1] (V1.0.1.68_1.0.1), where everything
(like this) works, my reserved addresses, like my static addresses, are
outside the (small) DHCP pool, and I know what all the reserved and
static addresses are, so I don't need to worry about any possible
conflicts.

Yes it is  D7000 V2   V1,0,0,51_1,01,

This Device which I access remotely to start a Computer, together with a Swann CCTV on the network.  Reading the logs you can see several times during a day it allocating different IP address to the device.   Somtimes the router reboots.

If I reboot the router it will take several hours before it shows any detected devices, and then gives the wrong IP Address.

If by "access remotely" do you mean that you are trying to view your setup from outside your home?

Unless you have a fixed IP from your ISP to use with your router, then your router's IP address likely changes every time you do a reboot.

No I have DNS service and can access router OK the PROBLEM Is the router does Not allocate the Reserved IP address, so when I try to turn the computer it does not work. If I them acces router remotely and change the Port forwarding to the IP address the router has given it works, but having do this each time is not acceptable. I am getting no relies from Netgear Support.

   Perhaps _you_ can.  Any clues to the reason?  Around here (D7000v1),
the DHCP server lease time is a day ("option  lease   86400"), so I
wouldn't expect anything to happen "several times during a day".

   Spontaneously?

   Did you ever try the diagnostics I suggested earlier ("Message 2 of
5")?

   With this much screwy behavior, I'd (also) be tempted to do a
settings reset, and a manual reconfiguration.

   I wouldn't hold my breath.  A formal support request would be more
likely to get a prompt response than a posting here would.

   If nothing else works, and the problem device has a wired connection,
then I might configure it with a static address (et al.), and use the
time I'd save to look for a more reliable router.  (If I were convinced
that the router was to blame.)
