I'm changing cable companies, and I'm going to wind up with a new cable router. My current router has a gateway ip address of the 192.168.1.x variety, and I have no idea if the new one will be the same. I'm running BI with 4 Dahua cameras with fixed IP addresses and no VPN. Is there anything I need to do before my new router is disconnected, or can I make all the necessary changes after the new one is installed?
