RBR40 and RBS40 generate different subnets for attached devices
I use RBR40/RBS40 mesh. Despite the fact that I have defined the subnet (192.168.0.x) for the LAN TCP/IP and directed to use Router as DHCP server with the starting and ending IP addresses within the...
I have found the "rogue" DHCP. My VoIP device had the internal DHCP server enabled. I turned it off, and the issue went away.
Thank you very much for your help.
Does the RBS show fully synced to the RBR on the RBRs web page?
Has a factory reset and setup from scratch with a wired PC and web browser been performed?

Might try this with the RBS in same room or near the RBR and setup from scratch using this process:

Thank you for your response.
I am not sure what the "fully synced" means. The attached devices tab shows devices connected to both the router RBR-40 and the to the satellite RBS-40. Moreover, the devices with IP addresses from both subnets appear connected to both router and satellite.
Fully Sync means the status shown on the RBRs web page shows GOOD or Wired for RBS that are ethernet connected.
Can you log into the RBS web page at it's assigned 192.168.0.# IP address?
Which devices are getting the different IP address from 192?
What Firmware version is currently loaded on the RBR and RBS?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

The status is GOOD.
To that "rogue" subnet connected all kind of devices, such as TVs, security, a tablet, a VoIP phone, Roku, a speaker.The router firmware version is V2.7.4.24.
The modem is Netgear Genie CM1150V firmware version V4.12.04.
Do these rogue IPs show up on the RBRs web page for each of these devices?
Can you post a screen capture of the RBRs web page with the MAC addresses redacted out?
Have you attempted to turn OFF all of these devices and then check the RBRs web page for devices, then turn them ON, one at a time then check the RBR web page and device to see what IP address gets assigned? Graduate turn them on one at a time to check the RBR and device?

As I mentioned in one of my previous responses, I have over 30 devices connected to the Orbi mesh network.Of those about the third connected to the "rogue" subnet 172.27.35.x. The rest are connected to the "prescribed" subnet 192.168.0.x.
Of the devices on the "rogue" subnet about the equal number connected to RBR and RBS.
To answer you how the "rogue" addresses are listed on the "Attached Devices" page, just imagine that in the column "IP Address" you see two kind of addresses: one kind starts with 192.168.0. and another start with 172.27.35. and the are mixed in the order.
I have downloaded WireShark and will try it later, when I have a bit more time.Thanks. Each device displays only one IP address? or do some devices appear two times in the display?
I am having a bit of confusion over how the heck the Orbi can communicate with devices in a different IP subnet.
