RBR750 DHCP
I have an Orbi RBR760 connected to my cable modem, also Netgear. My network Gateway / DHCP is 10.0.0.x. Works as advertised, most of the time. However, I noticed a number of connected devices that...
Thanks for the replies
The Modem is a Nighthawk AX6 (CAX30). WIFI disabled (in all of the many places it shows up). I have tried to turn off the router mode, the Orbi end of things then stopped working. I had to factory reset the Nighthawk to get back online. It does have a 170.x.x.x ip address from my ISP. DHCP for the LAN is 192.168.1.x the scope allows for only two IP addresses. firmware v1.4.10.8
RBR750 is in Router mode. Firmware v4.6.5.14, one satellite. Used to have two, one refuses to do anything, so I unplugged / deleted it. DHCP scope is 10.0.0.2 - 10.0.0.77
When I look at attached devices there are 6 that have 192.168.2.x for an IP address, and to add to the mystery, they all work / internet / all good. They show a gateway of 192.168.1.1 ARP -a presents me with the Orbi MAC address.
What I do not have is the DHCP scope of 192.168.2.x configured on any device on the network. Even if I was, it shouldn't work. I used to be a Banyan / Cisco network engineer, so this bother me.
While my Bandwidth and connectivity with the Orbi has been great, I find them extra special flakey.. I had a firmware problem last winter and Supports only answer was to do a hard reset. If I can't run this down, I may have to put the Orbi stuff on craigs list and go purchase something better.
Wow. What a puzzle!
To recap:
- The CAX30 WAN port has a public IP address.
- The CAX30 LAN port has 192.168.1.1
- Nothing is connected directly to the CAX30 besides the RBR750.
- The RBR750 WAN port has IP 192.168.1.2
- The RBR750 LAN port is IP 10.0.0.1
- The RBR750 DHCP range is 10.0.0.2 - 10.0.0.77
- The router Attached Devices page shows devices with both 10.0.0.x and 192.168.2.x IP addresses.
- When you dump the entire ARP table on a PC, there are entries with both 10.0.0.x and 192.168.2.x IP addresses.
Can you share the type of devices that have 192.168.2.x IP addresses?
