Network resets
For my own reasons I have my RBR50 configured to run on the network range of 192.168.100.x. Twice now the network range has been reset to 192.168.1.x with a message about the reason being the old rang...
I have no knowledge of how my ISP has configured the Cable Modem. I was offered the ISP's WiFi, but I prefer to run my own WiFi Router. I don't like to be limited to what the ISP says I should do. If you think the Cable Modem also has a 192.168.100.x address, I can configure to a different range. I picked this one at random. I don't like "default" network configurations and have a tendency to change things to make it harder to "someone" to break into my network or spoof me into thinking they know about my network. (How many have pressed the "Windows Tech Support" folks for at least the IP address of your computer and been told that it's 192.168.0.1?) For this reason, I change as many things as I can to make my system "non-default".
Yes, change your address range to something other than 192.168.100.0 and you should be good.
Search the below webpage for "192.168.100" and you will find discussions of Arris modems handing out DHCP addresses in the 192.168.100.X range. What you are seeing may indicate intermittent issues with your cable service. (Or power outages, or you pulled the plug, etc.)

From the above link: "When the modem can't access the cable infrastructure, it turns itself into a DHCP server and hands out IP addresses in the range 192.168.100.xx. This is useful for people at home whose configurations are such that their home networks won't work properly without some sort of DHCP server provided by the ISP."
- well, I've moved to a different range. Time will tell if that fixes the problem.
