What brand and model is the router connected to the CM modem? 

 

Power off the modem and disconnect the wifi router from the modem and connect 1 wired PC to WAN port#1. Power ON the modem, after it's ready can you connect to the modem at 192.168.100.1 at all?

Router is Orbi RBR50

The Modem does not have WAN port. It has LAN 1 and LAN 2. Do I connect my computer to LAN 1? Here is the photo of back of my modem.

    Use LAN 1 for your Ethernet connection.  Leave LAN 2 empty.  The CM1100 supports link aggregation which your RBR50 does not.

    THese are considered WAN ports as these are assigned by the ISP for WAN IP addresses. Yes, I have this modem as well. Good Modem.
