Sounds like a different network. If you cannot connect via IP then it's an IP conflict in the addressing or routing.
Example your ip is 192.168.233.2 but the IP of the router is 18.104.22.168
Unless you have the routing setup right you ain't never talking to the router on that one. You'd need static route added that told the router the 192 network is available via X link.
If you are trying to understand networking, instead of dick around and bullshit yourself; take CISCO CCNA classes at a community college. Costs nothing and you will understand networking from the ground up, for the rest of your life.
