Connecting a Router to a Router

[blazure]

So, we would like to get Internet from the new router and have it go through a second (old) router on one port and another wired connection on another port. Currently, when we connect the old router to a port, no traffic goes through and dns cannot be resolved. Are there any troubleshooting ideas?
