RBR860 gateway address wrong on DHCP
I'm not sure what is upstream of the router. It's cable, provided by an outsourced ISP, and their attitude is "we don't support you because it isn't equipment we supplied". I get a static public IP address and a static gateway IP address.
On the RBR860, I set the Internet access to these static IP addresses.
The LAN settings have an address of 10.0.1.1 for the router, and then a range of addresses for the LAN, using DHCP, starting from 10.0.1.2. I want to use both wired and wireless.
I am getting failures when connecting other devices, both Windows and Mac, both wired and wireless. They are set to use DHCP. The router/gateway address gets set to 10.0.1.2, when using DHCP. Any traffic fails, trying to use the wrong router address. If I set the IP address manually on the device and make the address for the router to 10.0.1.1, then the device connects happily to the Internet.
Any suggestions why the router IP address is returned as 10.0.1.2? I expected the DHCP server to return 10.0.1.1 as the default router.

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.Is the RBR Internet Setup configured for DHCP or Static WAN configuration?
What happens if you set the LAN side DHCP subnet to 192.168.1.1 and DCHP IP address pool range to .100 thru .200?
I don't know the details of the equipment upstream.
Internet setup is configured for Static WAN configuration, using the static IP address provided by the ISP. I've got good cable in place. This system has worked for a long time, only recently have I had problems with DHCP.
I can't really try the 192.x.x.x range of addresses, there's a lot of devices on the network, that's a big change.
In the document you link to, I have the same LAN settings (only difference, I'm using the 10.0.1.x range). It says there
The router delivers the following parameters to any LAN device that requests DHCP:
- Gateway IP address (the router's LAN IP address)
That's the bit I'm not getting, I don't get the router's IP address.
Will need to get the upstream ISP brand and model when you can. Important to know this info.
What Firmware version is currently loaded?Has a power off for 1 minute then back ON with the ISP modem and router and satellites been performed since last update?
Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on the router and wait 2 minutes for it to connect.
Turn on computers and rest of network.
Has a factory reset and setup from scratch been performed since last FW update?Try using the 10.0.0.1 subnet as a test and see if any devices get connected?

Kind of makes it hard to work out what is going on at your end.
Is this gateway something that sits between the RBR860 and the Internet?
If so, the "gateway" word is usually associated with something that handles the router stage of your network as well as the Internet connection. If that has its own IP address, then the fact that your router has decided to use 10.0.1.1 is a sign that you have "double NAT" conflicts.
Two routers on your network can cause headaches. For example, you can end up with local problems with addresses on your network. Among other things, the other router can misdirect traffic to addresses that the Netgear router usually handles, such as routerlogin.net or the usual default IP address for a router, 192.168.1.1.
This explains some of the other drawbacks.
What is Double NAT? | Answer | NETGEAR Support
It is often easier to use just one router and then to set up the second router as a wifi access point (AP) with a wired connection to the main router. Netgear advises this, as does just about every site you will visit.How do I change my NETGEAR router to AP mode? | Answer | NETGEAR Support
But that has its own drawbacks:Disabled Features on the Router when set to AP Mode | Answer | NETGEAR Support
If you can access the gateway through #a web browser and the graphical user interface (GUI) then there are other things that you cab try. Like putting the IP address it assigned to the RBR860 in the "DMZ".
The bottom line is that we don't know enough about your network.
Just another user with time on their hands.

You are correct. The Orbi router is supposed to supply its LAN IP as the gateway IP and the DNS server using DHCP.
Congratulations on being the first person (in my memory) to report this situation. 10.0.1.x is a valid LAN IP subnet.
I would not expect any device using DHCP to be able to reach the internet - nothing!
Could you post a screenshot of the top part of the LAN Setup page?
Just guessing: the 90 days of 'complimentary support' have expired, so contacting Netgear requires purchasing a support contract?
