Nighthawk AC1900 WAN IP address

[yodaster]

I have just purchased a Nighthawk AC1900 router to place between my BT Smarthub and my home network.  I have turned off DHCP in the BT router and the Nighthawl serves as the DHCP.  The BT router has an IP address of 192.168.1.254.  The Nighthawk has a 192.168.1.1 with a gateway of 192.168.1.254.  The DHCP pool is 192.168.1.2-253.  I run powerline externders throughout the house.  I have turned off the WiFi on the BT router and configured the Nighthawk is serving as the wireless access point.  The Nighthawk then revers to having a WAN ip of 10.0.0.1 and give the warning that is has changed to this to prevent confilct with the ISP.  Is there a command line interface for the Nighthawk?  I have nothing plugged into the WAN port on the Nighthawk, only 1 cable into the LAN port. 

Does anyone have any suggestions on how to change the WAN IP or explain what I am doing wrong.  Thanks much.

   "AC1900" is a speed, not a model number.  Look for "Model" on the
product label.  Firmware version?

> [...] to place between my BT Smarthub and my home network. [...]

   Why?  What is the actual problem which you are trying to solve?

   Does your (unspecified) "my BT Smarthub" have a modem-only mode?
That would open a different possibility.

> [...] I have turned off DHCP in the BT router [...]

   Why?  What is connected to this (unspecified) "the BT router"?
Anything other then the (unspecified) "a Nighthawk AC1900 router"?

   Hint: If a device has different types of Ethernet ports, then
"connected to device" is not enough detail.

> [...] The BT router has an IP address of 192.168.1.254. [...]

   A router like this typically has two IP addresses, one for its
WAN/Internet interface, one for its LAN interface.  Which one is this?
(LAN, I'd guess?)

> [...] The Nighthawk has a 192.168.1.1 with a gateway of 192.168.1.254.

   Unlikely.  A WAP normally does not offer a DHCP server.

> [...] The Nighthawk then revers to having a WAN ip of 10.0.0.1 [...]

   I'd expect it to do that when it's configured as a full-function
router, not when it's configured as a WAP.

   Nothing supported.  And what would you do with it if it had one?

   That suggests that you haven't done the following:

   Visit http://netgear.com/support , put in your (actual) model number,
and look for Documentation.  Get the User Manual.  Read.  Look for
"Access Point".

   _If_ you want to configure your (unspecified) "the Nighthawk" as a
WAP, that is.

   Aside from not reading the User Manual?  I don't yet know what you're
trying to achieve.

try wiring it like this and rebooting the system.

bt hub------->netgear wan port------->from lan port on netgear to rest of devices. 

only plug the netgear into the bt hub. And make sure the bt hub is going to the wan port on the netgear if the netgear is in router mode.
