Set up 2ed router for wifi end point....

I think end point is the correct term....

My current router is a Linksys WRT3200acm.......only issue is WiFi is weak at other end of house....
I picked up a Linksys E2500 (N600) that I would like to use to extend my WiFi signal....

I have a CAT5 line going to the other end of the house that I will plug into the E2500....

But how do I set up the E2500 to be an "end point"....

I assume I turn DHCP off and give it a static IP....
What else do I need to do...???

Thanks
Steve
