Orbi always loses configuration after cable modem reset
Hi - I have a Orbi RBR50 and one RBS50. My firmware version is V1.12.0.18 I have always had a problem where my Orbi base unit will lose its configuration information every time my cable modem res...
Your cable modem is hardwired with an IP address of 192.168.100.1. This is described in the manual here: http://www.downloads.netgear.com/files/GDC/CM400/CM400_UM_17July2015.pdf
With your Orbi setup to use a LAN IP of 192.168.1.1 and a subnet mask of 255.255.0.0 you have included the address space used by the modem in you LAN and created a conflict between the Orbi LAN and the cable modem's IP address. I'm not certain what's happening exactly, but it's very likely this is the source of your issue with Orbi sensing a conflict and resetting the LAN to 10.0.0.1.
You should change your Orbi LAN subnet to something different, like 172.16.X.X.
I'm curious. Why are you using 255.255.0.0? What are you doing that you need 65534 IP addresses on your LAN?
What subnet are you using for your Orbi LAN? For example, is it 192.168.100.X?
