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.

- Turned on DHCP server on a Raspberry Pi on the network Using a DHCP pool of 192.168.1.201 to 192.168.1.251 The Pi has two network interfaces: 192.168.1.29 (WiFi) and 192.168.1.30 (Ethernet)
- Started Wireshark to capture every packet going through my PC's Ethernet port.
- Ran the same command (
ipconfig /all | find /i "DHCP Server"and got NOTHING.- Then I ran the command ipconfig /renew, and Wireshark recorded this:
The Orbi (192.168.1.1) and both Raspberry Pi network connections responded with DHCP offers. Because the Orbi offer was received first, it was the one the PC accepted.
So, I am somewhat at a loss to understand the situation. (Like, why does that command work for you and not for me.) Most of the internet hits I got on searching for DHCP servers are at least 10-12 years old. (There were a bunch of programs written about 2009!)
These devices with the strange IP addresses:
- They have only a single network adapter?
- They show up in the Orbi Attached Devices list only once?
- This strange IP address shows up in the Orbi Attached Devices list?
