It's getting quite interesting this topic and I don't get 75% of what you are talking about as I am not IT specialist...
So you are simply saying to disable DHCP?
Yes, I assume you connect to the router via web browser
Disable DHCP, then note what the IP of the ROUTER is because this will be your DEFAULT GATEWAY, default I think is 192.168.1.1 could be wrong but it will look something like that
Then read this it should help
