Using Netgear Nighthawk router with G1100 & ?Actiontec extender

So I've read the posts about changing the GUI on the G1100 in order to use my new Nighthawk but maintain my TV/DVR service, and thought I'd gotten things right.  My Nighthawk has internet access and wifi, all of which work, but I somehow the 5G from the G1100 is still on and apparently still has internet access, too.  My dilemma now is that, for reasons I am unable to determine, I can't access the GUI in the G1100 or the Nighthawk, even when wired directly into them.  It doesn't matter which of the wifi I'm on either, so I'm frustrated.  I changed the settings on the G1100 per the post that includes assigning a new static IP to the G1100, disabling DHCP, etc.  I have an ONT ethernet connection to my Nighthawk, from Nighthawk to G1100.  The TV service is connected via coax from the G1100.

Did you follow REF https://www.dslreports.com/faq/11233

?

In my own words that FAQ.

#1 In the primary NAT router:

a) find the DHCP Range.

b) Make sure that it does not occupy the whole subnet.

c) If it occupy the whole subnet, make it smaller.

For example with it at 192.168.1.1 with the subnet mask of 255.255.255.0, the first DHCP Address that it handles out is 192.168.1.2 and the last DHCP Address that it handles out is 192.168.1.254 - then you could change it so that the first DHCP Address that it handles out is 192.168.1.100 and the last DHCP Address that it handles out is 192.168.1.254 

#2 For that other router, you must:

a) Have it disconnected at this step.

b) Set it's LAN IP Address with the same Subnet as the primary but outside of the DHCP Range of the Primary router's DHCP Range.

For example with the primary IP Address 192.168.1.1 with the subnet mask of 255.255.255.0, the first DHCP Address that it handles out is 192.168.1.100 and the last DHCP Address that it handles out is 192.168.1.254 - then the other router's LAN IP Address could be 192.168.1.6

c) Disable the DHCP Server in the second RJ-45 WAN port NAT router.

#3 Once you make those changes, now you can connect both of those routers together but this time LAN to LAN.

If not, have the routers not connected to each other and reset them and re do it correctly.

Like dslr says - disconnect your G1100, you should be able to connect to your other router.

While the G1100 is still disconnected, reset it, login (still not connected), make all your settings changes, shut it down, then plug in to the nighthawk (LAN-LAN) and THEN power it on.
